Air conditioning
Air conditioning means not only cooling but also regulating the entire indoor climate – temperature, humidity and air quality.

How air conditioning systems work
In principle, an air conditioning system works in the same way as a heat pump:
The liquid coolant flows from the outdoor unit of the system to the inside of the building.
On the way, the pressure is reduced and the temperature of the coolant falls below room temperature.
An exchange of air then takes place via the indoor unit of the air conditioning system, with the aid of a fan.
Whilst the room is cooled, the coolant heats up again and flows towards the outdoor unit.
The outdoor unit emits the heat, the coolant cools and the cycle begins again.
In heating operation, this cycle is simply reversed – the heat from the external air is emitted into the room via the indoor unit.
