Alilämmitys

Alilämmitys is a type of heating system used in buildings, particularly in cold climates. It is based on the principle of heat transfer through a heat exchanger, where a refrigerant fluid is circulated to transfer heat from a heat source to a heat sink.

The alilämmitys system typically consists of an outdoor unit, which houses the compressor and fan, and an indoor unit, which includes a heat exchanger, fan, and air distribution system. The refrigerant fluid is pumped between the two units through a series of coils, allowing heat to be transferred from the outdoor unit to the indoor unit.

In operation, the system works by using the compressor to compress the refrigerant fluid, causing it to release heat. This heat is then transferred to a heat exchanger, where it is absorbed by a fluid, such as water or air. The cooled refrigerant fluid is then pumped back to the outdoor unit, where it is reheated and the cycle is repeated.

Alilämmitys systems are commonly used in residential and commercial buildings in Finland and other Scandinavian countries, where the climate is cold and heating is a necessity. They are also used in other parts of the world with similar climates. The systems are known for their efficiency and ability to provide high-quality heat to buildings.
