lämmönkeruu
Lämmönkeruu refers to the process of collecting thermal energy from a source for heating or cooling purposes. This concept is central to various heating and cooling technologies, most notably heat pumps. Heat pumps work by transferring heat from a lower-temperature source to a higher-temperature destination. The "lämmönkeruu" phase is where the heat pump extracts thermal energy from its surroundings.
There are several primary sources for lämmönkeruu. These include ambient air, ground (geothermal), and water bodies
The efficiency and effectiveness of lämmönkeruu depend heavily on the chosen source, the climate conditions, and
