Definitions

  • the invention relates to a heat pump in which the first medium is circulated by a pump in an enclosed system with a heat exchanger, in which it is emitting heat to a second medium.
  • Ordinary heat pumps are working like known refrigerator olants in which the first medium is cooling the surroundings and transmits the hereby absorbed heat to the second medium which e.g. could be water circulating in a central heating plant.
  • the circulation pump applied for the first medium is usually operated by an electric motor.
  • the closed system is oil-filled, that the pump is an oil engine, and that the oil tubes of the heat exchanger have a flow passage cross section compressing the oil to a high pressure.
  • a high pressure means the rate of 3-400 ato.
  • the oil engine is installed in an insulated oil receptacle in the enclosed system, thereby utilizing even the waste heat of the pump motor.
  • the heat pump comprises an oil receptacle, in which is installed a pump 2 with an electric driving engine.
  • the suction side of the pump 2 discharges into the oil receptacle 1, whereas the pressure side of the pump through a tube 3 is connected to a heat exchanger.4.
  • the oil from the pump 2 is under substantial pressure directed through a helical tube with a relatively narrow flow passage, whereby the oil is heated.
  • the oil is * led from the tube 6 through a helical tube with a relatively large flow passage cross section, whereby the oil pressure wll be lowered.
  • water is likewise directed absorbing the heat from the oil.
  • the water supplied to the second heat exchanger 5 through a tube 8 can e.g. be return water from a central heating plant. From the second heat exchanger 5 the water is passing through a tube 9 to the first heat exchanger 4. From the latter the water heated in the heat exchangers 4 and 5 is directed through a tube 10 to the central heating plant.
  • the oil pump 2 is operated by a 4.5 kW motor with a capacity of 10 1/min.
  • the total quantity of oil being 33 1, and the specific heat of the oil being 0,5 cal/g/degree C.
  • a highly recommendable oil is the type of oil used in the hydraulic system of a jet aeroplane, as this kind of oil retains mainly a uniform viscosity over a large interval of temperatures.
  • the first heat exchanger 4 comprises a 40 m helical oil tube with an internal diameter of 4 mm
  • the second.heat exchanger 5 comprises a 15 m helical oil tube with a considerably larger internal diameter.
  • the return water in the tube 8 has a temperatur of about 50 degrees C, whereas the water having passed the heat exchangers in the tube 10 holds a temperatur of 60 degrees C.
  • the oil in the tube 6 between the two heat exchangers 4 and 5 has a temperatur of 60 degrees C, while the oil in the tube 7 has a temperature of 55 degrees C.
