The Different Types and Benefits of Aircon Models Used for Commercial Buildings and Homes

October 12,2017

Are you planning to install a new air conditioning system at home or in the office? With so many types such as window, ductless, and split aircon in the market, how do you pick the right one when considering factors such as the size of the room or space, the amount of heat generated in the space, the layout of the room or rooms, and other factors?

Aircon Systems Used in Commercial Buildings

Aircon systems used in offices and business spaces are designed to provide more cooling options for large spaces or multiple rooms over prolonged periods of time. They also include features that are not found in aircon models used for homes and are connected to more complicated ventilation and heating systems, thus the term heating, ventilation, and air condition (HVAC) is used for these commercial systems.

It’s no wonder that the installation, maintenance, and troubleshooting of commercial aircon systems are also trickier. When installing a new system, it is important to hire an expert aircon technician for the planning, purchase, and inspection of the units to ensure that you’re getting the best HVAC possible.

The following are the most common aircon systems used in various commercial buildings in Singapore.

  • Constant Air Volume. As the name implies, the CAV system produces constant air volume supply with its precise temperature and humidity control. They are generally energy-efficient, easy to control, and have a low initial cost.
  • Variable Air Volume. This is an aircon system which is made up of several parts for easier control of the heating and/or cooling options. What makes this ideal for most commercial spaces is the ability to control the temperature and humidity precisely through the reheat box or a terminal fan. It also has a low operating cost and has less ductwork.
  • Variable Refrigerant Flow. This model is recommended for medium-sized spaces such as hotels and retail buildings, because they can provide simultaneous heating and/or cooling, are installed easily, have low energy consumption, and are easy to control.
  • Chilled Beams. This is a system that uses both heating and cooling coils and produces air based on induction. They are sometimes used in combination with other aircon systems, because they produce a consistent air flow that reduces fan energy. However, they are difficult to maintain, because the water temperature and humidity must be constantly monitored.
  • Split System. This type of aircon system is the most recommended model for small commercial spaces such as shops, cafes, and offices with less than ten rooms, because they are cheap, energy-efficient, and are self-contained. The single split models, however, can also be used in combination with other single splits if the building has several rooms, although you will need more external space to house all the units.
  • Multi-Split System. This works similarly to the single split models, but you can connect up to nine units for slightly larger business or office spaces, such as restaurants, medical clinics, and large shops. Some businesses prefer the multi-split because they save space and can be mounted on the wall or ceiling so they don’t obstruct the view. However, they have a more complicated pipework and will take longer to install than the single split.


Aircon Models Used at Homes

Aircon models used at homes are much more compact and user-friendly than the commercial aircon systems, although both essentially use the same basic technology at heart. However, the installation, maintenance, and troubleshooting of home air conditioning systems by a licensed aircon technician in Singapore is just as important.

If you’re not sure which aircon model will suit your needs at home, talk to a trusted aircon technician to help you plan, purchase, and install the best aircon model you can afford.

  • This is the most common aircon model used for a single room, because it can easily fit in a wall slot or a window sill. Some of its benefits include energy efficiency, easy installation, compact design, and multifunction features.
  • Split or Ductless. The split type is composed of two parts that are found outdoors and indoors, and unlike the window aircon type, you do not need a slot in the wall because it can control the temperature in not just one but two rooms at the same time. Other benefits include lower running cost, efficient cooling system, and lower electric bills (as opposed to using several window aircon models).
  • The aircon system is found not just on the wall but in any part of the room. It can cool the room more effectively than the other models, but it is considerably noisier than the window and split types. It is ideal for very small spaces, such as a studio apartment or small bedrooms, and it dehumidifies and cools the space at the same time.
  • Larger homes need a centralized air conditioning system to avoid the use of several units that will use up more energy. In a central air conditioning system, a large compressor and packaged units are connected to the ductwork of both the heating and cooling system throughout the home. It makes less noise, improves air quality, and will not affect the view of the house because the units can be placed outdoors.
