  • a heat exchanger evaporator
  • a heat exchanger condenser
  • Some of the moisture contained in the process air condenses on the evaporator.
  • the condensate formed in the process flows away from the evaporator under the action of gravity and is caught or collected in a condensate pan of the floor pan which is arranged geodetically deeper than the evaporator.
  • the heat exchangers of the heat pump are arranged above the condensate pan in order not to come into contact with the condensate present in the condensate pan.
  • a partition is arranged above the condensate pan, on which the heat exchangers stand or which carries the heat exchangers. The installation space below

  • the evaporation of the refrigerant takes place predominantly in the evaporator of the heat pump.
  • the refrigerant flows into the evaporator as a mixture of liquid and gas.
  • the refrigerant then reaches a compressor of the heat pump as a gas, where it is compressed.
  • the compressor is also the drive that drives the refrigerant through the closed circuit.
  • the compressed refrigerant arrives from the compressor to the condenser of the heat pump, in which it is liquefied while releasing heat.
  • the liquefied refrigerant passes into an expansion device, in particular a valve, a diaphragm or a capillary, in which the internal pressure of the refrigerant is reduced and in which the refrigerant is already partially converted back into gas.
