What does air conditioning do?

Cooling
Air conditioners offer precise temperature control. You can always create a comfortable climate, with the right temperature. Not only does it create comfort, it makes you feel fresh and active whatever the conditions outdoors.

Heating
Air conditioners can also provide heating. You can enjoy a constant temperature all year round, no matter what the outside temperature. It is an environmentally friendly alternative to traditional heating because it takes energy from the outside air and brings it inside.

Cleaning
Air conditioners produce clean, healthy air. Indoor units are equipped with filters that take dust, pollen, smoke and other allergens from the air. The level of filtration can be increased if required.

Dehumidifying
In cooling mode an air conditioner dehumidifies the air. Correct humidity levels limit the growth of dust mites and moulds, which has a positive effect on allergy sufferers. 40% to 60% humidity is a comfortable level for humans, which also ensures a longer life of your house and appliances.

Ventilating
Ventilation can be integrated in to the air conditioning system. It extracts the inside air and pushes in fresh, conditioned air from outside. When the air conditioning is turned off, the ventilation can work independently. Ventilation systems can also be installed without the air conditioning installation.

How does it work?

In simple terms air conditioning works by absorbing energy in one place and releasing it in another place.

The process requires an indoor unit and an outdoor unit with copper piping connecting the two. Refrigerant flows through the pipes between the units. The refrigerant absorbs the energy in one unit and transfers it to the other unit for release.

Cooling Mode

Indoor unit
A fan blows hot indoor heat over a heat exchanging coil containing refrigerant. The cold refrigerant absorbs heat from the air and cooled air is blown in to the room

Copper Piping
Refrigerant circulates through the system via the copper piping, transferring the heat from the indoor unit to the outdoor unit.

Outdoor unit
Through compression, the refrigerant is heated and its boiling point increases. In the outdoor unit, the obtained heat is released to the outdoor air by a fan which blows the outdoor air over a heat exchanger.

Refrigerant
The liquid refrigerant flows back to the indoor unit.

Back to the Indoor unit
The refrigerant is decompressed which enables it to absorb heat from the indoor air and the cycle starts over.
