Definitions

  • GB-A-2 167 543 discloses a heat pump according to the preamble of claim 1.
  • a heat pump consists of a compressor 1 , whose suction is connected by a feed piping 2 with a coolant outlet 33 from a pair of heat exchangers 3 air/coolant. Coolant in the outlet 33 from the heat exchangers 3 air/coolant transmits the heat taken off the air.
  • the compressor 1 compresses this coolant, by means of which the coolant temperature further increased, usually to values around 85° C. Coolant is from the compressor 1 led into a heat exchanger 4 coolant/water. Water heated in this way is further used for a heat consumer, for instance for a building heating etc.
