Definitions

  • the invention relates to an electric heat pump according to the preamble of claim 1 and to a condenser module according to the preamble of claim 7.
  • Electric heat pumps in a so-called modular construction with components integrated in a common hood have been known for some time.
  • a cold, gaseous refrigerant is drawn in and compressed by a compressor.
  • the compressed refrigerant is then conveyed at elevated pressure and temperature via a line into the condenser, from which it emerges in liquid form after heat is removed.
  • a disadvantage of this known system is that pressure losses occur in the line and the condenser, which means that a correspondingly higher performance of the compressor is required.
  • the system also at least partially loses losses of the latter.
  • the compressed hot fluid can thus freely from the compressor and directly into the interior of this and at the same time penetrate the housing surrounding the condenser, or its inner wall structured as a condenser, whereby the pressure losses can be reduced to the absolute minimum, that is to say practically to zero.
  • the compressor losses can also be added to the overall efficiency, since heat is also transferred from the hot compressor jacket to the refrigerant.
  • the protection of the present invention should not only relate to complete electric heat pumps, but also to individual condenser modules within the meaning of claim 7.
  • the electric heat pump according to the invention is made in a manner known per se from a compressor 1, a condenser 2, a evaporator 3 and a thermostatically controlled expansion valve 4 constructed as main components.
  • the arrangement also includes the supply of the liquid refrigerant via line 6 to the evaporator 3, a solenoid valve 7 in the supply line 8 of the hot, gaseous refrigerant also to the evaporator 3 for the purpose of defrosting it and a filter dryer interposed between the condenser 2 and in the supply line 6 9 as auxiliary components.
  • a liquid separator 5 is connected upstream in the suction line 1.1.
  • the housing 10 In the interior of the housing 10, preferably in a concentric position, there is a heat exchanger in the form of a coil of coils wound from a finned tube as a condenser 2.
  • the compressor 1 is mounted inside the latter.
  • the compressor 1 encapsulates the two system components 1 encapsulated in the pressure-resistant housing 10 and 2 together with their connecting lines form the capacitor module 11.
  • the pressure-resistant housing 10 is also preferably surrounded by insulation 10.8 and has a heat and sound insulation.
  • the pressure-resistant housing 10 can be inseparably welded together to form an encapsulation of the capacitor module 11, which is inaccessible throughout its useful life, from a aforementioned components, namely the base 10.2, the cylinder shell 10.3 and the cover 10.4.
  • connection lines with the connections of the coolant circuit are marked in FIG. 2 with the following designations: 1.1 denotes a pipeline leading from the evaporator 3 to the liquid separator 5 and from there to the compressor 1, via which the compressor 1 sucks in the expanded, gaseous refrigerant from the evaporator 3.
  • the Refrigerant compressed under high pressure emerges from the compressor 1 via the pipe section 1.2 into the interior of the housing 10 surrounding the condenser 2.
  • the refrigerant condensed by giving off heat to the water flowing in the condenser 2 is collected at the deepest point of the bottom 10.2 which is curved downward. From there it comes to the connection of the pipeline 6 and the auxiliary components of the system arranged in the latter, but not shown in FIG.
  • All of the connecting lines 1.1, 1.3, 6 of the condenser module 11 which run to the evaporator 3 and also the hot water line connections 2.1 and 2.2 are each equipped with a plug-in quick-action coupling which is expediently acted upon by the internal pressure prevailing therein and is therefore automatically secured and not shown in the drawing.
  • the condenser module 11 or the integral electric heat pump module each represents a plug-in exchange unit.
  • a feed cable (not shown) is required.
  • the reference symbol 4.1 denotes the control line of the thermostatically controllable expansion valve 4.
  • the system and auxiliary components located outside the capacitor module 13 are the same as those in FIG. 1.
  • the condenser 2 forms at least part of the housing 10, the inner wall 14 and / or the outer wall 15 having structures 14, for example ribs, which increase the surface area to ensure good heat transfer.
  • This version also has the advantage that water connections leading into the interior of the pressure-resistant housing are eliminated, the condensation part or the structured inner wall still being located within the pressure-resistant housing.
  • the modular electric compact heat pump described above is suitable as an exchange unit, especially in the transition period, for individual heating of single-family houses, for floor heating depending on the heat output required individually or in parallel (instead of a large heat pump), but also as a cooling unit with integral heat recovery . It is able to provide 50 to 70% of the annual heat requirement of modern buildings and can also be operated with a water or glycol evaporator instead of the air evaporator 3 shown here.
