Top 10 Reasons for Regular professional Air conditioner Servicing



















Buying a new aircon is one of the most fulfilling things. You can control the quality of air in the room as you wish especially when it is hot and humid during the day. In fact, without a proper function aircon, it will be extremely difficult to enjoy indoor times in Singapore. The place is mostly known for the hot and humid. As you continue using the aircon as some point will need to be serviced. In most cases, the manufacturer will specify when the servicing should be done to ensure that it is operating at the highest efficiency possible.

Lack of proper servicing can cause the aircon to lose up to 5% efficiency, and the result will be a hike of operating cost up to 20%. Apart from maintaining efficiency, there are many other benefits of proper aircon services. These are the main reason reasons for why you should have regular aircon servicing:

• To improve air quality
The main purpose of an aircon is to improve the quality of the air circulating in a room. It is designed to provide a highly conducive environment to work in. When the air condition is new, it works at almost 100% efficiency and this ensures that the quality of air is top notch. If the effectiveness of the machine starts going down, it will lower the quality of the air. You need to have the aircon serviced regularly to ensure that the quality of air is maintained. Otherwise, you will never enjoy the benefits the machine is designed for.

• To increase energy efficiency
The efficiency of a machine is simply the state and quality at which the machine is operating at. Though no machine can hit the 100% mark, the best should be operating at 99%. If an Aircon is poor serviced or not serviced at all, it will lose its efficiency. This drop will have an effect on the quality of machine operation and the energy consumption- you will be paying more to maintain the aircon. Having it served properly serviced on a regular basis as advised by the manufacturer will help in maintaining and improving the energy efficiency.



• Reduce airborne disease risks
By cleaning the air, the aircon helps in removing allergens and bacteria that are known for causing the spread of airborne diseases. If the machine is denied the proper serving, it will not remove allergen and bacteria from the air effectively. The result will be spread of airborne diseases such as common cold, tonsillitis, and sore throat. The result will be low production in the office and sometimes the absence of the workers. How would it be if a client finds that everyone in the office is coughing? It is, therefore, important to have the machine serviced so as reduce the possibility of airborne diseases.

• Reduce cost of repair
Reducing cost of repair is one of the main benefits of servicing machines regularly. While servicing, you can easily identify the areas where the problem is developing from and collect it. This will reduce significantly the need to have some replaced or repaired. This is how the cost of repair will be reduced. If the aircon is allowed to run till it becomes faulty, then the cost of repair might be very high compared to when regular aircon services have been provided.

• Increased life span
With every servicing that is done, the machine is given a new life. It starts working again as if it was new. Regular maintenance ensures that the machine lifespan has been extended. One mistake that many people make is denying their air conditioners servicing hoping to save money. The potential danger is that it might, and one day it will just go silent. The damage might be too severe to the point that even repair cannot save air conditioner. These are challenges that regular professional servicing addresses.

• Reduce breakdown
What if one day you aircon just break down when you most need it. It can happen when you are having a general meeting with shareholders or meeting with friends at your home. Break down mostly comes as a result of failure to service and repair the defective parts of the machine. By hiring professional services, the possible causes of breakdown are identified early before and rectified. In fact, it is very hard to have a regularly serviced aircon breaking down unless you hired unqualified persons to do the job.

• Peace of mind and reliability
Nothing can provide a homeowner with peace of mind than knowing that an air conditioner is working properly. It can sometimes be annoying to know that you are operating with a machine that is likely to fail anytime. Having the machine serviced regularly will give you confidence that it is okay. You will have least worries that it is likely to fail you when you need it the most. It will also be highly reliable in the service delivery -the machine will be running at its best.



• Improved performance
An air conditioner performance will deteriorate with time. As the wear and tear affect the machine, the performance will definitely drop. To improve on this, you have to ensure that the aircon is serviced regularly and properly. Improved performance will also play a key role in ensuring that the best quality of air has been delivered to the room.

• Significant saving
By servicing the air conditioner regularly, it has been proved that it will reduce repairs and breakdowns. Both are situations that can cause you a lot of money if they happen. It is also true that a properly serviced aircon has less operational costs and this can specifically will be seen on power bills. The bottom line is that the machine will save you more money in the long run by servicing.

• To abide by warranty
For any air conditioner that you but, it must have a warranty. Though you are guaranteed to enjoy some privileges by having the warranty, you are also supposed to adhere to a set conditions including regularly having the machine serviced as scheduled. It is, therefore, important to have the aircon serviced for warranty purposes.

These are 10 of the main reasons why you should have your aircon professionally serviced. It is necessary mostly for the quality of air that is the main reason for buying an air conditioner. The benefits of regular aircon servicing are indeed immense. Hire a professional service provider if the manufacturer does not offer the service.

Serving Your Air Conditioner- All You Need to Know





















Singapore is warm most part of the year. But as the year nears the middle—around June and July, and the tropical rainforest climate set in, it can prove to be quite impossible to do away with an air conditioner.

But, as with all the mod cons you know, the only way the AC can provide that sweet, cool relief is when it’s in a very good working condition. You have to understand that an air conditioner works by transferring the heat inside your room to the outside environment, filling the room with cooler air from outside.

The mechanics involved could prove to be even more complex if you can get to learn how the contraption actually works.

It’s for such reasons that it’s recommended that you settle for only a good air conditioner. One that will be serving you for quite some time before you see the need to get it serviced or replaced.

How to tell if Your Air Conditioner Needs Servicing

You don’t need to be a rocket scientist to know if your air con is turning into a dud. All you need to watch for are the signs that calls for its repair. Then make sure the air con is repaired right on time, before it gets worse or stops working altogether.

Here are some signs to look for if you’re in doubt on whether or NOT you air con is in need of repair:

When it’s still hot in the room
This one should go without mentioning. When your room suddenly starts getting heated up, odds are the air con system has stopped working.

Try setting the system at full blast and see if the room is as cold as it used to be when you first installed the air con. Any downhill variation to the level of coolness the air con used to generate while still new indicates the need for repair.

For all we know, something could be wrong with the system’s compressor or the Freon’s level could just be too low. A good air con servicing company should be able to point out the exact problem before fixing it for you.



Excessive Noise
One thing we all look for in the air conditioner we buy is its ability to run smoothly in the background without creating any distraction or noise.

That’s to be expected of a new air con. But as time goes and the air con starts wearing out, you may start to hear some noises. This is a clear indication that some parts are loose or need to be replaced.

The noise could be emanating from the outdoor unit or the indoor unit. Whichever the case this is a clear indication that the air con is in thorough need of servicing.

Thermostat Problems
The problem doesn’t have to be the air conditioner itself. It could be the thermostat for all we know.

The easiest way to tell if the problem is the thermostat or the air con is to find out if the temperature in your house is evenly distributed in all rooms. If one room is cold and the other one hot, odds are the thermostat stopped working and should therefore be repaired or replaced.

A Pungent Smell
Unless you’re convinced the foul or pungent smell in the room is from something else, there’s a fair chance it could be as a result of one of your air con’s insulating wires burning out.

The best way to find out is to try and check out the direction from which the smell is coming from. If your nose is directing you towards the cooler, waste no time and call an air con servicing company.

When the system is Leaking Moisture
There shouldn’t be any moisture leaking from your air con system if it’s in a good working condition.

Reason being, moisture leakages could be a dead giveaway that your system is refrigerating.

Some people don’t find this problem serious enough to sweat for. But one thing you have to understand is that refrigerant leakages pose as a serious health risk. You might want to call a service company right away to save your family from the health complications associated with it.

Also, if the water pools happen to be next to the AC, odds are the drain tubes aren’t disposing properly. They could either be blocked or broken. It’s important that you have it fixed fast enough before it leads to a series of other serious problems including mold growth.

How to Extend the Lifespan of Your AC and Minimize on Repair

It’s to be expected that your AC will someday fail to work, if NOT fail to work efficiently. But there comes a time when the failure is as a result of pure negligence or failure to take necessary precautions when there was time for it.

That being said, here are a number of ways you can extend the lifespan of your air con or minimize on the number of repairs you make:

- Don’t Overwork it
It’s simple logic—the more you make your AC run, the shorter the lifespan and the more you’ll be calling for its servicing.

The best way to extend the life of your AC is to make good use of shades and blinds during the day. The air coming from outside through the window could be enough such that you won’t even see the need to put on your air con on some days.



You could also install an awning to shield your house from the intense sunlight coming from the south through the window.

Alternatively, you could also get a floor or a ceiling fan to run alongside your AC when the heat is NOT intense enough to necessitate its running.

- Schedule Maintenance Checkups
You could use the services of the dealer who helped you install the AC or get a professional company dealing with AC repairs and schedule yearly checkups and cleanups.

It’s good that you have the checkups slated before mid year when the climate will be at its hottest point and the AC will as such be running full time.

Here are some of the tasks you must ensure the company you settle for pays a special consideration to during the maintenance and checkup trips:

i. Inspecting and cleaning the coils

ii. Cleaning and replacing some of the filters

iii. Replacing and adjusting some of the fan belts

iv. Lubricating all the motors and bearings

v. Checking the AC refrigerant and pressures

v. Verifying the operating temperature

vi. Inspecting all controls and safeties

Why You Should Not Perform DIY Aircon Servicing





















Anyone working for a company offering aircon servicing could go on and on for days telling you about the horror stories of customers dealing with air conditioning breakdowns at the most inappropriate time of the year. Everyone fears the day when they turn on their air conditioning and feel nothing but warm air flowing out of the vents. Unfortunately, those horror stories and fears aren't enough to convince most people to keep up-to-date with their aircon services and some even go to the point of actually trying to fix the problems themselves.


The good news is you don't have to dwell on what could happen if you don't schedule your home for regular aircon servicing. You don't have to listen to all of those horror stories because the problems of those others have nothing to do with you and your home. You have enough to worry about and don't need to add the "what if" scenarios and fears to the list.

There is something related that you cannot afford not to think about, though. You cannot afford to stop thinking about how forgetting aircon services affect the comfort of your home. Below are some of the reasons why you should not perform DIY Aircon servicing rather, you should opt for professionals.

Your Home Environment

How hard do you work to keep your home clean and sanitary? How much time have you spent painting walls, putting up window treatments, and moving around furniture in your home? If you are like most people, you spend lots of time fixing up your home so it feels comfortable, warm and inviting to your loved ones and friends.

Part of setting up that warm environment is making sure that your air conditioning is working properly. When the air goes out you have the wrong kind of "warmth" in the home. Things get unbearable very fast and all the other comforting elements of your decor no longer matter.
Without the right skills, you will just make everything even worse and thus you should contact a reputable aircon servicing company to handle the issue and maintain the serenity of your home environment.

From Comfort to Safety

You now know how important aircon servicing is to the comforting vibe of your home, but it is also very important for the safety of everyone spending time in your home. This is especially true if you live with or spend a lot of time with the elderly or young children and babies.

The older and younger members of your family may not be physically equipped to deal with a breakdown of the air conditioning. Every year elderly people and children die because of the heat and all too often it is inside a home where there is no functioning air conditioning.

Preventing the Worst

If you sign up for aircon services and keep your appointments at least twice a year, you can cut out much of the worry over the comfort and safety of your home. When you allow an aircon servicing company to upkeep your home you drastically reduce your chances of experiencing a major problem with your system.

Since many elements of your air conditioning system are shared with your heating system, it is important to combine aircon servicing and servicing for your heater. The same technician can come into your home in the spring and fall to make sure your system is ready to pump out the air whether it is about to get cold or hot outside.



Over time, it's exhausting to maintain everything that goes wrong having a home. In the event you relate to all of this, you might be carrying out homeownership all wrong. There might be an easy method to accomplish things that won't be so exhausting.

Instead of fixing things simply because they fail, how about maintaining things before they really fail? It may be hard to think of things in this manner if you're always fixing things throughout the house, but there are things that are much better maintained than fixed.

Your Ac System

Maybe you need to replace parts of your ac. If so, you are aware how expensive and mentally draining it can be to handle ac problems. You might be real familiar with local companies providing aircon servicing during emergencies, but how familiar have you been with air con services that deal with maintenance?

Aircon servicing is one thing better carried out by maintenance than emergencies. Air con services should enter your house once every year to evaluate on the body. Most prefer to do this in the year, that is right before the season whenever you will probably be relying upon the body to cool your house. By performing aircon servicing at this time you make sure situations are working properly and all sorts of required part replacements are carried out before you decide to absolutely need your ac system.

It is much cheaper and time effective to own this yearly visit from your air con services than it is to simply fix the body when it finally gives out you.

Property Up Keep

It is always cheaper and the majority less hassle to look into the future. Instead of searching for what is going wrong with your home at this time, start looking as to the "can become a problem later on".

Maintaining over time is a constant chore, but it's a lot less stressful than fixing problems. You'll generally pay a smaller amount to maintain all aspects of your house than you'd pay to fix them when they fail. Additionally, you will possess a lot less drama and chaos in your life if your home is well maintained.



You do shoulder lots of responsibility whenever you become a homeowner. In the event you keep an eye on maintenance rather than fixing, you'll feel less stressed!

Also, its important to remember that anything worth doing in life will require consistency. You can't lose a large amount of weight without working out and watching what you eat consistently and you can't win the Olympics in your favorite sport without years of consistent hard work and perseverance.

The same thing goes with your aircon services. You have to be very consistent with your appointments so they are perfectly spaced around through the year. This type of dedication can save you lots of money as you avoid breakdowns and expensive part replacements over the years. This is essentially how you get the most from your aircon services.

7 Ways To Prepare Yourself For The Haze in Singapore







Haze is one of the most common occurrences in Singapore. Most of the time, it occurs between May and October. The most common cause is wild fires in the forests neaby Indonesia. Winds from Indonesia blow the smoke particles towards various parts of Singapore. Therefore, they affect the air condition in these areas.

In 2016, the condition is supposed to get even worse. It may reach hazardous levels. According to most studies and researches, the air quality in the country has been quite poor. It has been the major cause for a national environmental authority to announce that the air levels have deteriorated further to hazardous levels. In this post, we’ve discussed 7 effective ways to prepare yourself for haze in 2016.

Minimize Outdoor Activities 
Although it is almost impossible to escape from haze, you can minimize your exposure. People suffering from respiratory or heart ailments should reduce outdoor activities and physical exertion. Engaging yourself in strenuous activities may cause you to inhale some pollutants in the air into your lungs.

Take Precautions Indoors
Even when you’re indoors, you need to take some precautions. It is important to keep windows, doors and some other ventilation outlets shut. In case you’re using an air conditioner, you should only turn it on after ensuring that air vents and filters are clean. You should also invest some amount in an air purifier. Such devices can keep particulate levels in a closed space quite low.

If you want some organic choices, you should use houseplants like Snake plant or Chinese Evergreen to absorb some toxic pollutants. Plants also add more value to your house and make it look beautiful.



Wear a Mask 
You should not use any random surgical or paper masks. These turn out to be a waste of time and money. When it comes to harmful air particles, you should only use appropriate masks. Respiratory masks always prove to be more effective in keeping out harmful particulate matter.

According to experts, you should change the masks when they become distoreted or soiled. Respiratory masks can be easily obtained from local pharmacies. These days, you can even buy them online.

Boost the Immune System 
It is very important to take certain steps to boost your immune system. You need to exercise regularly to increase your body’s metabolic rate, and strengthen the immune system. A healthy diet is also very important. You need to take proper medications to eliminate cases of a runny nose.

In order to avoid any serious problems regarding haze, you need to reduce your intake of caffeine and alcohol. They can cause fluid loss and make your body lose more nutrients. In addition to this, if you’re experiencing any symptoms of excess mucus production, you should take certain steps to dilute mucus. This can be one of the most effective ways to prepare yourself for haze in 2016.

Close Windows in the Car
Whenever you’re outdoors, you need to take some steps to reduce your exposure to haze in Singapore. For instance, you should close all the windows of the car while driving. This can help you against polluted air. In addition to this, you should also cover your nose and mouth with a mask. If you’re already suffering from asthma, you need to be even more cautious. Certain precautions will help you avoid an unnecessary asthma attack.



Keep Yourself Hydrated
The best way to prepare yourself for haze is to keep yourself hydrated. It will allow your kidneys to flush out toxins which might have been absorbed by your skin and lungs. You should also take care of your diet, and increase your intake of Vitamic E and C. Vitamin C includes certain foods like strawberries, oranges, and guavas. On the othe rhand, Vitamin E mostly includes nuts and seeds. It is also better to include Omega-3 fatty acids in your diet.

Consult a Doctor Immediately 
In case you experince any symptoms associated with haze, including cough, shortness of breath, dry eyes or runny nose, you should seek medical attention immediately. This is even more important for people suffering from skin conditions like eczema or breathing problems like asthma. It is very important to monitor your health and consult a doctor regularly. In 2016, it will be even more important to take certain precautions to prepare yourself for haze in Singapore.

How To Plan Your VRV System Design



















If you are looking for the right answer to the question as to how VRV or Variable Refrigerant Volume air conditioners could be useful, then the next few lines could be interesting and informative. When buying air conditioners, we keep in mind quite a few things. Amongst them initial cost of purchase is perhaps the most important consideration. However, we must also keep other things in mind such as the recurring energy costs, durability, longevity and other factors and attributes. It would also be pertinent to mention here that the look and feel of the air conditioning unit when it is set up in the home or workplace is also an important consideration when it is being purchased. In this article we will try and have a look at the reason why there is a growing demand for VRV system designed air conditioners. We will also try to find some answers to the question how to plan your VRV system design.

Why It Could Be A Great Option
The VRV system design is relatively new technology and therefore not many people might be aware of it. However, when it comes to complete, cost effective and great looking designs and air conditioning solutions, there are reasons to believe that going in for VRC would be a good option. However, it is important to have some basic idea about these designs and systems and only then should one move forward. Over the next few lines we will try and have a look at the various things to be kept in mind when it comes to planning the best VRV system design.

Have Clear Idea About The Space To Be Covered
Though VRV is a proven technology and is known for its efficiency and versatility, before going in for this method of air conditioning, you must have the right design plan available with you. To begin with it is ideal to opt for ductless air conditioning design features. Secondly, you must also be aware that these VRV air conditioners come in different capacities. There are a few which are designed for commercial purposes and there are others which are specifically suited for residential spaces. There are also single room VRV solutions suitable for small room sizes of around 200 to 300 square feet. Hence the first starting point is to have a clear idea about the area that is planned to be covered using these air conditioning designing systems.



Long Term Sustainability
You have to bear in mind that these air conditioning systems are expensive and therefore they should be suitable and sustainable from the long term point of view. They do help a lot in saving on electricity and energy consumption because of their inbuilt features. They do come with inverters and outdoor units having dual compressor units. Hence when going in for design features, you should be sure that it provides constant cycling and offer the best of load matching capabilities even when there are wild swings in voltages. The temperature fluctuations outside might be very unpredictable and could oscillate from one extreme to the other in countries like Singapore. Hence when going in for the VRV system design, this factors should also be taken into account.
Design Features

An air conditioner apart from protecting the inmates from too much of heat and cold also plays a big role in adding style and sophistication to the room. It gives a special look and ambience. Therefore this aspect should be kept in mind when it comes to coming out with the design features for your VRV system. The walls should be built differently and the air conditioning system should match with the overall color scheme of the room.

Choosing The Right Types
When we talk about VRV systems, we usually refer to two major types. They are pump systems with pump heat facility and pipe heat recovery type. While both can perform the function of heating and cooling, the former can do only one at a time. On the other hand the latter will be able to perform both the tasks simultaneously. In other words it can regulate different temperatures in different rooms and closed places keeping in mind specific needs and requirements. Hence, when going in for system design for VRV units this point must always be kept in mind.

Complete User Control
One of the major differences between conventional air conditioning units and VRV units is the number of condensing units, including evaporators and compressors. However, when you decide to go in for a VRV unit, you can have one conduction unit which can be connected to many numbers of evaporators. Each of these evaporators can be controlled individually. Hence, this is a very important aspect to be kept in mind when it comes to choosing the right design for your VRV system.



Take The Help Of Professionals
At the end of the day there is hardly any doubt that VRC is a recent technology and it is also quite complex and complicates. As end users it might not be possible for us to find out the right design structures which are needed to get the maximum benefit out of it. Under the above circumstances, the best way forward would be to take the help or professionals engineers and architects before you install these systems. It would be always advisable to seek their counsel and advice before even designing or constructing the room or space where the air conditioning units will be sitting. This will help you to get the best out of it in terms of performance, energy efficiency, longevity, durability and finally the best value for money.

Conclusion

At the end of the day there is hardly any doubt that VRV is going to be future as far as air conditioning technology is concerned. We might have homes where different members of the family would like to have different heating and cooling systems. In such an eventuality the best of VRV designing systems with the best of cooling and heating systems would certainly make a big difference. It is all about gathering the right information and knowledge and then moving forward based on what the experts have to say.

Pros & Cons On Casement Aircon





If you are a resident in Singapore, then having an aircon is essential for you to have a comfortable life in your home. With the help of a good quality aircon you can control the temperature of your home as per your preference. But you can have worry free and comfortable life in your home only if you will have right kind of aircon for same. Since there are several type of aircon available in the Singapore, so choosing the right one can be a complicated task for people. So, here I am sharing some pros and cons on casement aircon and you can take your decision for same in wise manner.

Benefits of casement aircon 

Easy to install: If we compare the installation part then a spilt aircon will have various parts in it and you will need to install that all to get it working. You may need to do various diggings for aircon cooling pipes and draining pipe in a spilt aircon system. However, things are not that much complicated to install a casement aircon in your home. You just need to do the fitting of casement aircon on your window and then you can get it working quickly. That means it will be really easy for you to do the installation and you will be able to have better outcome for same with ease.

Ideal for small homes: If you have a small home or room then a casement aircon is perfect for that. It can do the cooling for your small room in easy ways. That is definitely a great benefit of this kind of aircon system because when you reach to home, then you wish to get quick cooling. A casement aircon does fast cooling for you and that is defiantly a great benefit that you can get with this particular aircon system in your home.

Fewer risk involve: If you live in an apartment where you have lack of space for installing outside unit of aircon, then you will need to install the outside unit on the windo or on grill. This will be a risky subject because if that outside unit fall down, then it can damage so many people. Other than this, it can cause more money as well to you. At the other hand you do not need to worry about the security part with casement aircon. It slid down inside a well attached system and it remains connected with your window in a firm manner. So, you will have fewer risk attached with it.

Need less permission: In an apartment you may need to take a lot of permissions to install the outside unit of split air conditioner. However, you need almost no permission to install the casement aircon in your home. In fact most of the places will allow you to install it without any issue and if you need any permission then you can have that permission also with ease.



Cost effective: One more amazing benefit of casement aircon is that it is highly cost effective compared to other options. Most of the split AC can charge you more money compared to casement aircon. So, if you have less budget to install an aircon in your home then you can try this option and chances are really high that you will get one in your budget that too with great ease.

Drawbacks of casement aircon

No easy to refill: Any AC would not give proper cooling to your unless it had enough amount of cooling liquid in it. That means if your casement aircon will lose its coolant or if you need to refill it, then it will not be an easy thing in any ways. In fact, you may need to take out the entire unit for that and after that you will need to do the refilling. Overall, this will be a very complicated and tedious process for you and you may need to hire some expert for that.

Not good for bigger areas: If you have a bigger area or bigger house, then casement aircon might not be a good solution for you. For smaller rooms it can do great work, but it may not do the proper splitting of cool air in the entire room. Due to this issue you may not get cooling at other corners of the room. IF you wish to have proper cooling in your bigger home, then you will need to get in touch with bigger areas. That will be one of those things that you may need to keep in your mind while choosing it.

Less energy efficient: While most of the modern day spilt aircon are highly energy efficient, we can’t say the same thing for casement aircon. Mostly this kind of aircons are not highly energy efficient and sometime it may increase your electricity bill in a negative manner. So, when you install it then you may need to keep thing also in your mind to avoid any kind of complication or trouble.



Make more noise: If you like to have a comfortable house, then you may not get that using casement aircon. This particular aircon makes a lot of noise in your house and you may not have a comfortable good night sleep while using it. So, if you are ok with noise, then you can go ahead with this option, but if you are not fine with sound, then you will not be able to get better outcome for same in easy ways.

In addition to this there are so many other things are also there are goes in favor of casement aircon and so many other factors are also there that goes against it. So, when you think about choosing casement aircon for your home, then make sure you keep these things in your mind. And if you will do your serch wisely, then this is an assurance that you will get only the best outcome with it and you will not have any kind of other complication as well.

All That You Need to Know About VRV Aircon







With the ever increasing demand more efficient Aircons, many manufacturers have been trying to come up with products that meet the customers’ expectations. It is a fact the aircons’ quality has been improving every day thanks the innovativeness of the manufacturers. Among the best aircons that the market has ever seen are the variable refrigerant volume commonly referred to as the VRV. VRV is a relatively new HVAC system that has been in existence approximately 30 years. It was a technology that was developed and introduced into the market by Daikin, a Japan company and a leading manufacturer of HVAC in the world.

VRV is a protected name by the Daikin Industries who invented this technology and thus, other manufacturers have resulted into using the term variable refrigeration flow (VRF). The working principles of both are same. VRV is a multi-split type air conditioner that is designed for commercial building application and large homes. What makes it effective for these kinds of premises is the fact that it can control the temperatures of individual rooms independently. VRV aircon is designed with a single outdoor unit that connects to multiple indoor units. These indoor units are the ones that are installed in individual rooms where they are operated independently by a room thermostat while the outdoor unit provided the required refrigeration.

Technically, VRV is an air conditioning/heating system that connects multiple indoor units through the refrigeration piping to a single outdoor unit. It may come as a heat pump or a heat pump with heat recovery system. The heat pump with heat recovery system allows the indoor units to select either the heating or cooling modes regardless of the mode at that the outdoor unit is in. But this is different in heat pump systems where the indoor units rely on the mode that the outdoor unit is in.

To achieve such variations, VRV is installed with an aircon inverter which adds a DC inverter to the compressor and this supports variable motor speeds. It is these variable motor speeds that allow for variable refrigeration volumes to enable independent control of indoor units.

VRV system is indeed on of the greatest HVAC systems in the market and it is doing incredibly well. But like any other device, it has its pros and shortcomings.



Here are some of the main pros that are associated with VRV aircon:

• High energy efficiency
The energy efficiency of this system is incredibly high. Compared to the traditional aircons, VRV will save you up to 50% of the energy consumption. This cut in cost has been achieved by the fact that there is only one outdoor system that is controlling all the indoor systems. If it were traditional aircons, each of the indoor system would be connected to its outdoor system. You can imagine a commercial building with more than fifty rooms and how many HVAC systems would be required and the energy needed to run them. Installing VRV will eliminate all outdoor systems and this is how it helps in cutting the cost of the energy thus improving the efficiency of running the entire system.
