Definitions

  • the present invention relates to a chamber for housing the components of the refrigerant circuit of a heat pump, provided with means to avoid excessive overheating of some of said components.
  • the invention falls within the sector of the thermodynamic machines for heating and/or cooling a residential or industrial environment; in particular, the present invention is specifically suitable for a monobloc heat pump for outdoor use, having the compressor and the refrigerant circuit confined in a separate chamber from the evaporator.
  • a housing chamber having at least one wall (but preferably each wall) equipped with a soundproofing system designed according to a "mass-spring-mass" principle, i.e. walls made up of three layers of different material (a first inner wall layer of soundproofing material, a second intermediate wall layer of sound-absorbing material, a third outer wall of soundproofing material), suitably coupled to ensure a high acoustic insulation degree from the sound waves produced by the aforementioned compressor and by the other components of the refrigerant circuit.
  • a “mass-spring-mass” principle i.e. walls made up of three layers of different material (a first inner wall layer of soundproofing material, a second intermediate wall layer of sound-absorbing material, a third outer wall of soundproofing material), suitably coupled to ensure a high acoustic insulation degree from the sound waves produced by the aforementioned compressor and by the other components of the refrigerant circuit.
  • the acoustic insulation contributes to raising the temperature inside the same, at the expense of the energy efficiency of the thermodynamic cycle and with the risks that a temperature level not compatible with the correct operation of some of said components is reached.
  • the purpose of the present invention is to obviate such kind of problems, by providing a housing chamber for the compressor and at least part of the refrigerant circuit of a heat pump, innerly provided with a heat-insulating casing which helps reducing the inner temperature and avoids excessive overheating of the circulation pump.
  • any dimensional and spatial term refers to the positions of the elements as shown in the annexed figures, without any limiting intent relative to the possible operating conditions.
  • figure 1 shows a heat pump, specifically an air-water heat pump of the monobloc type for outdoor installation: however, what is described hereinbelow may be extended to any other type of heat pump, for example of the water-water or air-air type, or even to similar thermodynamic machines.
  • At least one of said walls comprises, in sequence, from the inside to the outside of the chamber 1, the following layers of material:
  • the increased dimensions of the aforesaid additional accumulator SA are such that a part of the same (preferably the substantially lower part) is not wound by the thermo-insulating casing 2, so that the cold walls of such portion outside the casing 2 exchange heat directly with the interior of chamber 1.
  • thermo-insulating envelope 2 inside chamber 1 may usefully take place even in case that said chamber 1 is devoid of any soundproofing system, when it is also desired to obtain the aforementioned advantages of a lowering of temperatures and, in particular, the operating temperatures of components such as the circulation pump P and the expansion valve EXP.
