AC units

AC unitsBefore buying an air-conditioner, you should always obtain reliable information on the various types of commercial air conditioning systems for your HVAC needs.

There are many types of HVAC units available on the market for commercial buildings, which are all designed to provide fresh air to keep the interior at a constant temperature and preserve air quality. A properly maintained system can surely provide a comfortable indoor environment all year round. Explore the various types of commercial air conditioning systems:

Split Air Conditioner

A split air conditioner has both an indoor air-handling unit and an outdoor condensing unit. The outdoor unit is installed outside the room along with a compressor, condenser, and expansion valve. The indoor unit includes the evaporator and the cooling fan. Split systems are typically used in small commercial buildings to cool one or two rooms. Today’s split units are attractively designed and do not take up much space.

Heat Pump

Heat pumps feature a special valve in the refrigeration piping to allow the refrigeration cycle to be operated in reverse. A heat pump can both cool and heat the indoor air by reversing the valve. Air source heat pumps use the outside air as its heat source in heating mode, and as its heat sink in cooling mode. An additional electric resistance heater can assist the heat pump at lower outdoor temperatures. During cold seasons, be prepared to defrost the heat pumps.

Packaged Air Conditioner

Packaged air conditioners are designed to cool more than two rooms or larger offices. There can be two arrangements with the package unit. First, all the components such as the compressor, condenser, expansion valve, and evaporator are fitted in a single box. In the second arrangement, the compressor and condenser are fitted in one casing. The compressed gas passes through individual units, with the expansion valve and cooling coil placed at different rooms.

Now that you know more about the different options available to you, it should be easier to purchase the right HVAC system for your building’s requirements.
