Furthermore, the invention relates to a method for generating heat of compression with a liquid pumped through a throttle into the liquid container and for transmitting the generated heat of compression to a fluid to be heated.
  • the cold water inlet is located in the area of the bottom of the steel container; the process is located near the upper end.
  • the cold water introduced into the steel container is heated by the heat given off by the heating coil system as a result of the flow of the heated oil. Consequently, heated water can be withdrawn above the drain.
  • a regulator is used for temperature detection the water in the steel container and controls depending on the measured temperature to the pump.
  • JP 56119490 A a thermal power plant is known in which the pump circuit is designed as an open circuit.
  • An oil container filled with oil serves as an oil balance tank and as a container for arranging a heat exchanger.
