Definitions

  • the present invention relates to an air-water compression monobloc heat pump.
  • an air-water compression heat pump has a heat transfer fluid circuit intended to draw heat from the ambient air and to transfer it to a water circuit directly or indirectly providing a heating function; the air set in motion by a fan gives up its heat to the heat transfer fluid circulating in a heat exchanger called an evaporator and the fluid returns this heat to the water put into circulation in a heat exchanger said to be a condenser generally constituted by a coil with coaxial tube.
  • the refrigerant circuit includes, o r be the evaporator and the condenser, a compressor and an expander.
  • a monobloc heat pump In a monobloc heat pump, almost all of the aforementioned component parts are grouped in the same body arranged outside the room for storing or using hot water.
  • the connection between the body and the room is made by means of a thermally insulated and doubled water pipe to allow the outward flow and the return flow, as well as by means of at least one cable d and control.
  • the object of the invention is in particular to simplify the construction and installation of a one-piece air-water heat pump without adversely affecting its performance, by including the condenser coil in a closed box constituting a support base at least for the compressor assembly of the heat pump, this compartment being filled with a thermally insulating material and being exposed to the ambient air by its only lateral surface.
  • the box also constitutes a support base for the evaporator assembly of the heat sink.
  • the base of the heat pump adds to its function of supporting the pump components (compressor assembly, evaporator-motor-fan assembly and casing) a highly insulating housing function for the condenser. It also forms a sub-assembly that is easy to manufacture and store.
  • the heat transferred by the heat transfer fluid to the water circulating in the condenser in fact undergoes minimal losses since the base of the heat pump is surmounted by the compressor compartment and is in contact with the ground or a screed attached to it. this ; moreover, a moderate layer of snow is enough to insulate the base and to further reduce heat losses in cold weather.
  • the base may have a flat bottom in contact with the ground or the screed; it can also be manufactured by molding in metallic or synthetic material, the insulating material preferably being an insulating foam injected in situ around the coil.
  • the heat pump illustrated in FIG. 1 comprises three assemblies, namely an evaporator assembly 10, a compressor assembly 20 and an assembly con density 30, as well as a covering 40.
  • the evaporator assembly 10 includes a motor-fan unit 11 with variable speed as a function of the outside temperature, an evaporator 12 with a helical exchanger coil, an air outlet grille 13 and soundproofing means 14.
  • the compressor assembly 20 has in a cover 21, the compressor 22, a power and diagnostic unit 23 and a regulation unit 24.
  • the compressor 22 and the housing 23 are mounted for example on slides 25 which facilitate the extraction of these components.
  • the condenser assembly 30 comprises a closed box 31 containing an exchanger coil 32 constituted by a coaxial counter-current tube embedded in a filling 33 made of insulating material; this filling is for example a polyurethane foam injected in situ into the box to fill it completely.
  • the box 31 constitutes the base of the heat pump and in particular supports the compressor assembly 20.
  • the base 31 is removably attached to a concrete screed 34, with the interposition of a layer of bituminous felt 35, by means of a screw 36 cooperating with a threaded plug 36a embedded in the screed.
  • the head of the screw 36 is housed in a recess in the upper face of the base 31.
  • a lateral annex 37 is removably attached to the box 31 to form a housing for the hydraulic and electrical connections 39.
  • the thermal insulation of the condenser coil 32 results both from the integral insulating filling 33, from the immediate vicinity of the compressor assembly arranged on the upper face 41 of the box 31, from the laying of the flat bottom 42 of the box on the ground by the layer 35 and screed 34 and the exposure of the air box by its only cylindrical lateral surface 43 capable of isolation by a layer of snow in cold periods.
  • the base 31 of the heat pump is manufactured for example by molding in a metallic or non-corrodible synthetic material. It has on its upper face 41 elements for holding the components of the compressor assembly 20, for example the slides 25 previously mentioned, and housings 44 for vertical rods 45 supporting the covering 40.
