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.

Claims (5)

  1. Wärmepumpe, die ein Paar der Wärmeaustauscher (31, 32) Luft/Kühlmittel aufweist, die mit deren Ausgängen (33) an die Zuleitung (2) des Kühlmittels angeschlossen sind, die mit dem Eingang des Kompressors (1) verbunden ist, dessen Ausgang mit dem Eingang des Wärmeaustauschers (4) Kühlmittel/Wasser verbunden ist, dessen Ausgang mit der Rücklaufleitung (5) des Kühlmittels verbunden ist, die auf zwei Zweige (51, 52) aufgeteilt ist, von denen jeder mit einem Verdampfungseingang (310, 320) von jedem der Wärmeaustauscher (31, 32) Luft/Kühlmittel verbunden ist, dadurch gekennzeichnet, dass der erste Zweig (51) der Rücklaufleitung (5) des Kühlmittels vor dem Eingang in den Verdampfungseingang (320) des zweiten Wärmeaustauschers (32) Luft/Kühlmittel als die erste Anwärmleitung (81) gebildet ist, die mit dem ersten Wärmeaustauscher (31) verkoppelt ist, und der zweite Zweig (52) der Rücklaufleitung (5) des Kühlmittels vor dem Eingang in den Verdampfungseingang (310) des ersten Wärmeaustauschers (31) Luft/Kühlmittel als die zweite Anwärmleitung (82) gebildet ist, die mit dem zweiten Wärmeaustauscher (32) verkoppelt ist, und jeder der Zweige (51, 52) der Rücklaufleitung (5) des Kühlmittels verschließbar ist.
  2. Wärmepumpe nach dem Anspruch 1, dadurch gekennzeichnet, dass die Zweige (51, 52) der Rücklaufleitung (5) des Kühlmittels die Absperrventile (9) aufweisen, die mit der Steuereinrichtung verkoppelt sind.
