ulkoyksiköllä
Ulkoyksiköllä refers to the outdoor unit of an air conditioning or heat pump system. In split systems, which are common for both cooling and heating, the system is divided into two main parts: an indoor unit and an outdoor unit. The ulkoyksiköllä is responsible for heat exchange with the outside environment. It typically houses the compressor, condenser coil, and an outdoor fan.
During cooling mode, the ulkoyksiköllä expels heat absorbed from the indoor air into the surrounding atmosphere.
