Definitions

  • the present invention relates to a combined refrigerating/hot water device comprising a compressor for compressing the refrigerating fluid, a condenser for condensing the refrigerating fluid from the compressor, a capillary tube for expanding the refrigerating fluid from the condenser, evaporating means for evaporating the refrigerating fluid from the capillary tube and, finally, a return pipe connecting the outlet on the evaporating means to the input on the compressor.
  • the condenser is placed inside a cistern of a water-heater for heating the water inside.
  • a further drawback of this solution is that the freezer and cistern must be connected by two pipes in which the refrigerating fluid flows at a pressure of usually around 10 Atm.
  • the aim of the present invention is therefore to overcome the above drawbacks by providing a device for collecting the heat dissipated through the condenser on food refrigerating and/or freezer appliances, that can be connected easily and cheaply to a cistern of a normal electric water-heater though with little or no effect on the normal efficiency of the said appliances without the heat collecting feature, thus providing for considerable saving in energy.
  • Further aims of the present invention are to avoid having to run the high-pressure refrigerating fluid pipes from the refrigerator to the cistern and to provide simple, ordinary means for connecting the said two appliances so as to enable maximum freedom of choice as to the position and distance between the appliances and make installation of the said device as simple and fast as possible.
  • the present invention relates to a combined refrigerating/hot water device
  • a compressor for compressing the refrigerating fluid
  • a condenser for condensing the refrigerating fluid from the compressor
  • a capillary tube for expanding the refrigerating fluid from the condenser
  • evaporating means for evaporating the refrigerating fluid from the capillary tube
  • a return pipe connecting the outlet on the evaporating means to the input on the compressor, characterised by the fact that means are provided for heating the water by collecting and storing the heat available on the condenser, the said means being connected to a tank of water by connecting means comprising a pipe, as well as means for regulating the flow of water so that cold water can only circulate from the bottom of the tank to the water heating means and the hot water only from the heating means to the top of the tank or hot water pipe.
  • top-loading freezer 1 comprises compressor 2 for compressing the refrigerating fluid, condenser 3, 4 for condensing the refrigerating fluid from the compressor, capillary tube 5 for expanding the refrigerating fluid from the condenser, expanding means, not shown in the diagram, for evaporating the refrigerating fluid from capillary tube 5 and return pipe 6 connecting the outlet on the evaporating means to the input of compressor 2.
  • the condenser has been divided into two parts: the first, in the shape of a coil, 3, is placed inside an insulated storage tank 7 full of water while the second, 4 , is left exposed.
  • Storage tank 7 has two 3/4" coupling marked 8 and 9 which act as an inlet and outlet for receiving and supplying water from and to cistern 13 respectively.
  • One end of pipe 10 is fitted to coupling 8 while the other is fitted to flow regulating valve 11 which will be described in more detail later on.
  • the other two apertures on valve 11 are connected one to input 12 of cistern 13 and the other to external cold water pipe 14.
  • Coupling 9 is connected to one end of pipe 15 the other end of which is connected to "T" fitting 16.
  • Pipes 10 and 15 are ordinary water pipes capable of withstanding the 8 Atm pressure, the safety valves on standard cisterns are usually set to.
  • this shows a flow regulating valve 11 consisting of : a 1 ⁇ 2" coupling 19 the cold water from mains pipe 14 flows in through; a space 20 closed off at the bottom for allowing the cold water to flow straight into cistern 13 along inlet pipe 12; and a centre pipe 21 which is longer at the top than inlet pipe 12 and allows the water at the bottom of cistern 13 to reach inlet 8 of storage tank 7 via 3/4" coupling 22 and pipe 10.
  • Fig. 2 also shows part of cistern 24 and water inlet pipe 12 on cistern 13.
  • coil-shaped condenser 3 for heating the water and exposed part 4 depends on the temperature the water is to be heated to, the condensation temperature the refrigerating fluid is used at and the efficiency required from freezer 1. If overheating or -cooling of the refrigerating fluid is to be avoided (in view of the slight fall in freezer efficiency involved), a special refrigerating fluid for operating at a condensation temperature of 70-80°C could be used.
  • electric resistor 23 The function of electric resistor 23 is to ensure hot water is produced even when freezer 1 is not running as well as to supply the energy needed for heating large quantities of water which the heat collecting device alone could not bring up to the required temperature.
  • valve 11 The function of flow regulating valve 11 is therefore to isolate storage tank 7 from the main water circuit and ensure it only "communicates" with cistern 13. Another advantage of valve 11 is that it prevents sharp changes in temperature around the condenser (i.e. the water in tank 7) which provides for better sizing and more rational use of the entire refrigeration circuit.
  • the top part of pipe 21 could be made of flexible material, e.g. plastic, capable of withstanding operating temperature so that it can be fitted more easily into ordinary cisterns of water-heaters on which it may be difficult to fit pipe 21.
