When things come for a selection then the difficult situation generates, because there are too many options are available for everything in the market. A vast number of variables are present in the market for you. You can select yours one according to your desire. The same is applied to commercial ACs. There are too many systems on the market to count. If you are confused then I positively hope that my article can help you for selecting the commercial air conditioner.
Single Split System:
Single split systems are the best option for small buildings. It is the most famous kind of commercial air conditioning system. Single split Ac work with an outdoor unit to circulate air, which passes through the building’s ducts. At very affordable rates they permit you to control the temperature in each room with a control panel. The key benefit of single split Ac is that if one gets out of order and needs to be repaired, the other systems around your building will continue working because each unit is self-contained.

Multi-Split System:
As compared to a single split system multi-split system can save your space, because a single split requires an outdoor unit per indoor unit. But in the case of a multi-split system single outdoor unit provides power to nine indoor units that you can install onto the wall or ceiling. No need to spotlight that each multi-split system is able to spot temperature changes. When this happens the unit self-adjust, which means less energy consumed. Now inverters are available and we should thank them, each air conditioner has the ability to perform at various speeds. But the negative fact of a multi-split commercial air conditioner is that they need more piping so they might be not suitable for all buildings.
VRF or VRV System:
VRF stands for variable refrigerant flow and VRV stands for variable refrigerant volume, these two names are for the same commercial air conditioning. The buildings are the best option for huge buildings and it is available in two designs. Few VRF/VRV systems use a heat pump function that cools the place with open floor plans. VRF or VRV systems secondly use a heat recovery system that cools while using waste heat for hot water. The benefits of VRF OR VRV air conditioners are; its first feature is we can install it very fast, it is easy to operate, and the key benefit is it is reliable.
VAV or CAV System:
VAV stands for variable air volume system and CAV stands for constant air volume. These two names are for the same commercial air conditioning. These air conditioners are ideal for large spaces. It has a major benefit of its supply and returns function is that they use a single duct. It keeps the temperature at the point you set it at. You can easily control it with a thermostat, which directs the damper to the correct position based on your default settings.
Conclusion:
These all commercial air conditioner have their own benefits. I hope this overview will help you to select the commercial air conditioning for your building. If you need air conditioners for small buildings then choose a single split system, it is also cost-effective. But if you have a lack of space then give preference to a multi-split system. On the other hand, if you need air conditioners for larger buildings, for larger buildings you have two options VRF OR VRV air conditioners and VAV or CAV air conditioners. But the CAV uses only a single duct. So all the functions of these common types of commercial air conditionings I have narrated. Pick that one who suits your urges.
What Is a Commercial Air Conditioner?
A commercial air conditioner is a cooling system made for a large building, such as an office, a shop, a school, a hospital, or a factory. It is larger and more powerful than a home air conditioner, because it must cool a large space with many people, lights, and machines. A commercial system often has more than one indoor unit, a large outdoor unit, and a network of ducts or pipes that carry cool air or refrigerant around the building.
Choosing the right commercial air conditioner is important, because the wrong system can cost too much to run, cool some rooms too much and others too little, and break down often. A good system keeps the temperature steady, uses energy well, and is easy to maintain.
More Types of Commercial Air Conditioners
Packaged rooftop unit: A packaged unit sits on the roof of a building. All the parts are in one box, which makes it easy to install and to service. It is common in shops and offices with a flat roof.
Chiller system: A chiller cools water, and the cold water is pumped around the building to cool the air. Chillers are used in very large buildings, such as hospitals and hotels, because they can cool a large area with one central system.
Ductless mini-split: A ductless system has an outdoor unit and one or more indoor units, with no ducts. It is good for a building with no ductwork, or for cooling a single room or zone.
VRF or VRV system: VRF stands for variable refrigerant flow, and VRV stands for variable refrigerant volume. The two names are for the same type of system, which was first made by Daikin. A VRF system can cool some rooms and heat others at the same time, and it can change the amount of refrigerant that goes to each indoor unit, which saves energy.
How to Choose a Commercial Air Conditioner
| Factor | What to check |
|---|---|
| Size of the building | Floor area, ceiling height, and number of rooms |
| Number of people | More people means more heat, so a larger system is needed |
| Climate | Hot and humid places need a system that also removes moisture |
| Energy use | Look for a high SEER or EER rating, and for inverter technology |
| Noise | Check the noise level, especially for offices and schools |
| Maintenance | Choose a system with easy access to filters and parts |
Cooling power is measured in tons or in British Thermal Units, known as BTUs. One ton of cooling is about 12,000 BTUs per hour. A professional should do a load calculation, which is a check of how much cooling the building needs, before you choose a system. A system that is too small will run all the time and still not cool the building. A system that is too large will turn on and off often, which wastes energy and wears out the parts.
How to Care for a Commercial Air Conditioner
- Change or clean filters often. Dirty filters block air flow and make the system work harder. Check filters each month, and change them when they are dirty.
- Clean the coils. The outdoor coil should be kept clean and free of leaves and dirt, so heat can leave the system.
- Check the drains. A blocked drain can cause water to leak inside the building. Check the condensate drain often.
- Book a yearly service. A trained technician should check the refrigerant, the electrical parts, and the controls each year, before the hot season starts.
- Use a thermostat well. Set the thermostat to a steady temperature, such as 24°C, and avoid changing it often. Use a programmable thermostat to save energy at night and at weekends.
Frequently Asked Questions
What is the difference between VRF and VRV?
VRF stands for variable refrigerant flow, and VRV stands for variable refrigerant volume. They are the same type of system. VRV is the name used by Daikin, which first made the system, while VRF is the general name used by other makers.
How long does a commercial air conditioner last?
A commercial air conditioner often lasts 15 to 20 years with regular care. The exact life depends on the type, the use, and how well it is maintained.
How can I save energy with a commercial air conditioner?
Keep filters clean, set the thermostat to a steady temperature, use a programmable thermostat, and book a yearly service. An inverter system, which changes its speed to match the cooling need, also saves energy.
What is a ton of cooling?
One ton of cooling is about 12,000 BTUs per hour. It is a measure of how much heat the system can remove from a building in one hour.
Do I need a professional to install a commercial air conditioner?
Yes. A commercial air conditioner should be installed by a licensed professional, because it needs the right size, the right refrigerant, and safe electrical work. A poor install can lead to leaks, high bills, and a short life.
