Definitions

  • the present invention relates to a heat pump system of the kind defined in the preamble of Claim 1, and to an arrangement for facilitating the exchange of a refrigerant unit forming part of the system.
  • a fault in known heat pumps which in many cases form the sole means of heating dwellings, such as houses and apartments, or entire housing districts, can cause heating to be interrupted for several days, before the fault is repaired.
  • the amount of freon present in the heat pump exceeds 3 kg, it is necessary to summon an authorized refrigeration engineer and to transport necessary equipment to the location of the pump in order to drain refrigerant from and return refrigerant to the system, or alternatively to fill the system with fresh refrigerant.
  • the fault cannot be repaired on site, it is necessary to take the faulty component to a repair shop or to return said component to the gene- ral supplier.
  • the loss of heat and the loss of hot tap-water creates a great deal of discomfort and irritation, and even if a reserve heat ⁇ ing facility is provided, this facility is often under- dimensioned and perhaps difficult to start-up.
  • a further object of the invention is to reduce the freon content of such systems to less than 100 g for each kWh delivered by the system, by provi ⁇ ding a compact constructional method and through the use of highly effective components, therewith enabling the layman to carry out work on systems having a power rating of up to 30 kWh.
  • Figure 1 is a block diagram illustrating a heat pump system
  • Figure 2 illustrates the mechanical construction of the system in a cabinet intended therefor
  • Figure 3 illustrates an arrangement for lifting and transporting a refrigerant unit.
  • FIG. 1 is a block diagram which illustrates an ex ⁇ emplifying embodiment of a heat pump system.
  • the system includes a heat pump unit which is generally referenced 1 and which includes a refrigerant circuit comprising a compressor 5, a first heat-exchanger 6 which is con ⁇ nected thermally to a heating system located externally of the heat pump unit and generally referenced 2, an expansion valve 7, a filter 8, and a second heat- exchanger 9, which is connected thermally to a heating source located externally of the heat pump unit 1 and identified generally by the reference numeral 3.
  • the refrigerant circulated in the circuit consists of one of the refrigerant types retailed under the designation freon.
  • the heating system 2 includes a water heater 20 having an inlet side connected to a cold water pipe KV and an outlet side connected to a hot water pipe W. Connected in series with the water heater 20 are three heating elements 21 and a circulation pump 22 mounted in the heat pump unit 1 feeds a heat transporting medium, normally water, from the heat exchanger, through a heating loop in the water heater 20, and from there through the elements 21 back to the heat exchanger 6.
  • the heating system includes two valves 23 across which the connection to the heat pump unit 1 is made.
  • the heat source 3 includes a pipe loop 31 which is connected to the second heat-exchanger 9 and which is intended to be mounted in a bore hole in the ground for instance, for the purpose of utilizing ground heat.
  • the loop carries a freezing-point lowering aqueous solution which is pumped around the loop with the aid of a circulation pump 32 mounted in the heat pump unit 1, said unit also including an expansion vessel 33 and valves 30 fitted in the connecting pipes.
  • Figure 2 illustrates a cabinet 10, from which the front panel has been removed and which accommodates the heat pump unit 1.
  • the cabinet is constructed from a frame ⁇ work 19 of square tubes and the top of the cabinet is provided with four pipe connectors 24 to which the pipes of the heating system and of the heating source respectively are connected. Also provided is a lead- through 25 for electrical wiring.
  • a control panel 26 mounted at the top of the front of the cabinet is a control panel 26 provided with switches and control lamps.
  • an electrical connector panel 27 mounted beneath the control panel is an electrical connector panel 27, which is normally covered by a front plate and on which the electrical installations are mounted.
  • the cabinet is mounted on a base frame 13 which rests on the foun- dation surface 14. Extending from the base frame 13, in the four corners of the cabinet are spacer supports 12 on which a bottom plate 11 is detachably fitted.
  • the components of the refrigerant circuit are assembled on the bottom plate 11 to form a unit which can be easily removed from the heat pump unit and replaced with a further refrigerant unit and which is released from the remainder of the heat pump, by opening the four pipe couplings 28 and moving the flexible pipes or hoses 29 to one side and by also disconnecting the electric cables (not shown) from the compressor 5 and also disconnecting a transducer or sensor (not shown) from the control equipment. Subsequent to releasing the refrigerant unit, the unit can be easily withdrawn from the cabinet for service or for replacement.
  • the arrangement includes a rectangular outer frame 15 made of angle iron and having vertically dis ⁇ posed outer sides with the horizontally arranged legs of the angle iron facing towards each other.
  • the length of the frame corresponds roughly to twice the depth of the cabinet 10 and mounted in the one half of the outer frame is a raisable and lowerable inner frame 16.
  • Mounted on the vertical inner surfaces of the inner frame 16 are rollers 17.
  • rollers 17 are mounted in a manner such that in the raised position of the inner frame said rollers will partially project up over the edge of the outer frame 15 and form a roller conveyer together with rollers 18 mounted in the other half of the outer frame and projecting up over the frame edge. Subsequent to having lifted the bottom plate 11 of the refrigerant unit away from the base frame 13, with the aid of the inner frame 16, the bottom plate 11 carrying said unit can be withdrawn from the cabinet 10 and transported along the foundation surface 14 with the aid of transport rollers 19 mounted beneath the outer frame 15.
  • Raising of the bottom plate 11 is made possible by the fact that the vertical extension of one half of the outer frame 15 of said transport device is so adapted that said frame half will fit exactly into the space between the base frame 13 of the cabinet and the bottom plate 11.
  • the inner frame 16 can be displaced relative to the outer frame 15, by means of a lever arm mechanism 34-36, and locked in this new position, the inner frame having reached this position by rolling on rollers 37 up and along keys or wedges 38 fitted on the outer frame 15.
  • the bottom plate 11 is lifted from the supports 12 by the rollers 17 and can be moved out over the transport rollers 19, as described above.
  • the unit When mounting a refrigerant unit in a heat pump cabi ⁇ net, the unit is positioned on the transport rollers 19 of the second frame half of the outer frame and moved to the cabinet, whereafter the one frame-half with the inner frame 16 in its raised position is moved in over the frame part 13 of the cabinet and the refrigerant unit can now be rolled into the cabinet.
  • one outer frame-half of the transport arrange ⁇ ment has been lowered against the base frame 13 of the cabinet and is locked to said base frame by the weight of the refrigerant unit.
  • the inner frame 16 is lowered with the aid of the lever arm mechanism 34-36 such that the bottom plate will now rest on the supports 12 and is screwed firmly to said supports.
  • the heat pump is ready to be started-up.
