How Air Conditioning Works

Air Conditioning can both cool and heat your environment while filtering the air and removing humidity providing the required level of comfort, regardless of the weather conditions.

HEATING is provided economically by "reversing" the operation of the conditioner. Instead of expelling the hot air and circulating cool air it does the reverse - hence the term 'reverse cycle' air conditioning.

There are various types of air conditioning systems and configurations, from the simple and inexpensive room air conditioner to the more elaborate split and ducted systems, so talk to one of Jaicrest's air conditioning engineers to find out which solution is best for you.

How Heating Works

When switched to the heating cycle a valve simply reverses the flow of refrigerant, so that heat is gained by the outdoor coil and used to heat the inside air.

The operation of the heat pump is possible because even on very cold days usable heat can be extracted from the outside air.

How Cooling Works

When cooling, the air conditioner operation is similar to that of the home refrigerator. The indoor air circulating fan draws air into the conditioner through an air filter and over a cold coil (containing refrigerant), cooling the air before it is circulated back into the room.

In addition to being cooled, the air is dehumidified when moisture in the air condenses on the cold coil. This condensate is caught in a drip tray and drained away.

The refrigerant carries the heat absorbed by the cooling coil (evaporator) to the outdoor heating coil (condenser) via the compressor and expansion and reversing valves. The outdoor air circulating fan forces air over the hot condenser coils, cooling the refrigerant.
