Definitions

  • the invention relates to a device for hot water by wastewater heat recovery by means of a compressor and an evaporator having heat pump, in particular by means of a small heat pump for household applications, with a hot water tank, which is fed by the evaporator of the heat pump with heat energy.
  • the recovery of waste heat is usually realized in known from the practice devices by wet steam cycle.
  • the compressor used in this heats up during operation usually to temperatures in the range between about 70 ° C and 90 ° C, which are thus usually much higher than the maximum of 60 degrees lying temperature of the hot water tank. Due to this elevated temperature, the compressor releases significant heat to the environment, which can easily be more than 50 watts. This compressor heat is lost so that the small heat pump does not achieve sufficiently high efficiency for economical operation.
  • the hot water tank is in thermal communication with the compressor of the heat pump via at least one heat pipe, wherein the hot water tank is disposed above the compressor and wherein the at least one heat pipe to a discharge of waste heat during operation of the compressor to the hot water tank is used.
  • the invention further proposes that the heat pipe is connected in good thermal contact by means of a unilaterally or bilaterally unsolvable connection by gluing, welding or soldering to the hot water tank or the compressor.
  • the heat pipe is connected in good thermal contact by means of a unilaterally or bilaterally releasable connection via fixed to the hot water tank or the compressor connected clamping pieces or similar connection means.
  • the heat pipes consist of at least partially elastically formed tubes. This initially allows a largely free choice of positions of hot water tank and compressor, only assuming that the compressor is located lower than the hot water tank. Due to the elastic design of the pipes of the heat pipes, the vibrations occurring during operation of the compressor can be absorbed more easily, so that they are not transmitted to the memory. This allows for a total quieter operation of the device.
