System for commercial HVAC

A heating, ventilation, and air conditioning (HVAC) system is a must-have system for any residential, industrial, or commercial building. The system keeps the indoor environment conducive for occupants by controlling the humidity, temperature, air quality of the building.

- COmmon types of
HVAC Systems-

Split HVAC System

The split HVAC system gets its name from the way it's set up as well as its components. The system comprises of the following parts:

  • An indoor unit, such as an air handler

  • An outdoor unit, which is the condenser 

  • A programmable or non-programmable thermostat

  • A humidity control or filtration system

  • Ductwork, which moves conditioned air from the system to the building

There are two types of split commercial air conditioners:

  • Single-split

  • Multi-split

Single Split System

The single-split is an affordable commercial air conditioning system that is suitable for small spaces such as cafes, server rooms, shops, and offices. The compact system is easy to install, and this is why it’s preferred for new buildings or renovated commercial spaces.


  • Cheaper to install and, therefore, ideal for small commercial spaces

  • Each of the units is self-contained. Therefore, if one breaks down, the others will still be working.

  • Energy-efficient. Each indoor unit can be used to deliver air conditioning only to the room that needs it.

  • The best solution for a single room that requires an additional HVAC system


  • It occupies a lot of space as it has an outdoor unit for each internal unit

Multi-Split System

With multi-split systems, you can connect several indoor units to one external unit. These systems are usually installed in larger spaces such as retail shops, doctors' units, and restaurants.

A multi-split system has a lot of pipework and needs to be properly installed. Get a professional to do the job as installation mistakes can reduce your HVAC efficiency by 30%.


  • Takes up less space. One outdoor unit can be used with several indoor units.

  • It preserves the external appearance of your building

  • The installation doesn’t require your building to have ductwork


  • The installation cost is higher

  • The installation can take longer as there is more pipework to be done

VRV or VRF System

The Variable Refrigerant Volume (VRV) or Variable Refrigerant Flow (VRF) system uses a refrigerant as its heating and cooling element. This is the best system for use in medium or large commercial spaces since it has a single condenser that can be used for more than one evaporator.

Each of the system’s internal units uses Electronic Expansion Valve (EEV) to control the refrigerant supply, ensuring it is in line with the demand from the building space.

There are two types of VRV system:

  • Heat pump systems, which are used for either cooling or heat pumping. These are large multi-splits units that are more efficient for open spaces.

  • Heat recovery systems, which can cool and heat buildings simultaneously. The systems save energy and are ideal for use in commercial spaces comprising of several rooms.


  • Ideal for medium and large commercial spaces

  • Easy to install in buildings under expansion

  • Quick installation without inconveniencing occupants of the building


  • Expensive to install

  • If the unit breaks down, the whole HVAC system will be affected
