Definitions

  • the invention relates to a heat recovery system for cooling systems with evaporators and refrigeration units, as are usually used in agricultural operations for cooling the milk or in larger food businesses for cooling meat, poultry and other goods.
  • Heat recovery systems that operate with a heat exchanger operating in a water tank is arranged.
  • the heat exchanger gives off the heat to the water contained in the water tank, so that the water tank heats up slowly. If the water in the water tank has reached a higher temperature, the efficiency of the system is worse, that is to say, extremely speaking, when the water in the water tank has reached the same temperature as the heat in the compressor, there is no longer any heat exchange and the residual heat must be above that known air condensers are dissipated. Such systems do not work well either.
  • the invention has for its object to provide a heat recovery system with which cooling heat and thus otherwise lost energy can be sensibly recovered to the limit of what is theoretically possible.
  • This object on which the invention is based is achieved in that a countercurrent condenser is connected to the compressor of the refrigeration unit, which is fed by the normal water line, the refrigerant coming from the compressor being returned to the system after cooling down and the heated water flowing to a water storage tank in the upper region thereof, which is connected to the normal water pipe in its lower area.
  • the water storage tank is equipped with an additional heater.
  • the countercurrent condenser circuit formed in this way can be switched on and off as desired by the main system according to a further feature of the invention, the procedure preferably being such that this countercurrent condenser circuit and the water storage tank are combined in a compact system which can also be easily connected to existing systems .
  • the countercurrent condenser is outside the water storage tank and that the water introduced into the countercurrent condenser is released directly into the storage tank.
  • thermostatic sensors check valves, safety devices, etc. are of course provided, which make the corresponding control of the entire working group safe and simple and as automatic as possible.
  • the heat recovery system is seen schematically at 9 and consists of a countercurrent condenser 1 0, which connects at 11 to the line of the compressed refrigerant and is fed at 12 with water from the normal water line.
  • the water supplied at 12 flows through the countercurrent condenser and arrives in a water storage tank 14, specifically in its upper area, this water storage tank 14 also being exposed to the normal pressure of the water pipe in its lower area, as can be seen at 15.
  • the additional electrical heating for the water storage tank can be seen and at 17 the heated water is drawn off from the water storage tank.
  • the separation between the hot water area and the cold water area in the water storage tank 14 takes place thermodynamically, ie there is no partition wall here.
  • the dash line provided in the drawing in The separation area between hot water and cold water is only shown to clarify the boundary and is not actually designed in this way.
  • valve means enabling the connection of the heat recovery system 9 to the conventional refrigeration system are only shown schematically in the drawing and it goes without saying that further thermostat controls, such as can be seen at 18, can be provided on the water storage tank.
