What are the Different Types of Commercial HVAC Systems?

13 March 2020

Commercial buildings require a system that can manage and regulate their overall temperature and ventilation. This system, which is known as heating, ventilation, and air conditioning (HVAC) system, can do the temperature regulation on the said buildings. Aside from temperature, the HVAC system can also remove contaminants in the air, which helps prevent the spread of contagious diseases.

To date, HVAC systems are grouped and classified into three major types. 

Single Split System

One of the most popular types of HVAC systems is the single split system since it is affordable and suitable for most small commercial buildings. This type of system can effectively control the temperature of small offices, server rooms, shops, restaurants, and other small commercial spaces.

The single split system has an air conditioner for you to cool the refrigerant. It also has furnaces and an evaporator coil that can convert the refrigerant and circulate the air through the ducts. A thermostat or control panel is present for the control of the whole system. One benefit of using this type of HVAC is that functional units will still work even if there is one damaged unit. One drawback, however, is that each indoor unit requires an outdoor unit, which can take up a lot of space.

Multi-Split System

Alternatively, a multi-split system allows you to connect up to nine indoor units with one outdoor unit. This specific ratio can save you a lot of space when compared to the single split system. For the system to operate at variable speeds, inverter technology is used specifically for this type of system.

Through the inclusion of special sensors, the use of a multi-split system can help you detect changes in temperature. As the changes are detected, the system will then make necessary temperature adjustments that will match the optimal one. The heat pumps of the system also work with the natural inclination of heat to move around your vicinity. Both of these components help you save more money and energy compared to furnaces and air conditioners. One disadvantage of this system, though, is that it will cost you more money to install the whole system since it requires more pipework.

VRF/VRV System

The variable refrigerant flow system (VRF)/variable refrigerant volume (VRV) system is most suitable for buildings that are spacious and huge. Commercial buildings such as retail or large office space, hotels, and others can maximise the use of this system. This system can be grouped into two: heat pump and heat recovery.

A heat pump system can give your building heating or cooling functionality, which can be a great system for open plan areas. A heat recovery system, on the other hand, can provide heating and cooling altogether, which is recommended for buildings with numerous smaller rooms.

VRF/VRV systems are reliable, efficient, and easy to control. They are also flexible and won’t affect your daily business operations while installing them. Contrarily, the purchase and installation costs of these systems are deemed higher than other systems.
