Commercial air conditioning comes in both centrally driven systems and local systems. Traditionally offices tended to have a central cooling and heating fan unit whereby the temperature controlled air is distributed throughout the building by a system of ceiling or floor ducts. A series of ventilation grills and baffles are balanced to ensue an even air distribution throughout the building.
However, modern technology allows many inverter units to be run off a single compressor and this is an alternative method of providing air conditioning to commercial premises. Technological advances allow long refrigerant pipe runs of up to 170m and the small diameter pipes which are now used result in less volume of refrigerant gas.
A slightly more complex solution would be to adopt a system with standard gas boiler heating as a backup. This method will help you to overcome are the issue if you are in a low temperature climate.
If inverter units are used in commercial buildings, these are often ceiling cassettes which come in a variety of specifications (1, 2 and 4 way cassettes). Perimeter areas and corridor areas often use air conditioning console units. Wall mounted inverter units are common throughout commercial buildings and are now becoming increasingly used in hotels. The attraction of these units is the opportunity for residents to control inverter output temperatures locally and very accurately. Most commercial air conditioning installations have state-of-the-art control equipment often centrally based but with local sensing. Computer based control units are now available that integrate functions such as temperature control, lighting, alarms and fire protection functions.
In heating mode, liquid refrigerant in the outside coils extracts heat from the air and evaporates into a gas. The indoor coils release heat from the refrigerant as it condenses back into a liquid. A reversing valve, near the compressor, can change the direction of the refrigerant flow for cooling as well as for defrosting the outdoor coils in winter. When the outdoor temperature drops significantly, a less-efficient panel of electric resistance coils, similar to those in your toaster, kicks in to provide indoor heating. As a result, air-source heat pumps are no very efficient for heating homes in areas that are subjected to prolonged cold spells.
