of refrigerating units.
“Dismantling”.
Operating principle of
heatpumps
Heat pumps operate on the same principle as a refriger-
ator: same technology, only with reversed benets. The
refrigerator extracts heat from foods, which is released
into the room through ns on the back.
The heat pump extracts heat from our environment:
air, earth or ground water. The extracted heat is condi-
tioned in the unit and supplied to the heating water. Even
when it is extremely cold outside, the heat pump draws
enough heat to heat a house.
