Definitions

  • the invention relates to a device for generating refrigeration in a closed Refrigerant circuit for cooling a refrigerant, in particular of a water-brine mixture, with a compressor in the refrigerant circuit gaseous refrigerant drawn from a steam drum and compressed and with supplies high pressure to a condenser, from which the liquid refrigerant after a pressure release across the liquid space of the steam drum Evaporator is supplied in which the refrigerant by the evaporation of the Heat is removed from the refrigerant and from which the gaseous refrigerant Steam space is fed to the steam drum again, the Heat exchanger surface of the evaporator as a plate heat exchanger with im Cross-countercurrent to each other and formed media Liquid space of the steam drum is arranged.
  • Such devices for refrigeration which are also called compression refrigeration machines are known from US-A-3 538 718.
  • the heat exchanger in the Center of the housing arranged so that it is a distance from all Has side walls of the housing.
  • this is also known Construction by liquid evaporation of the refrigerant in the heat exchanger Refrigerant entrained to the surface of the liquid level, which then sinks back to the bottom of the steam drum due to the density differences, however, this circulation takes place without being influenced by the arrangement of the Heat exchanger in the housing. Because of this, it is necessary to have both a Device for regulating the liquid level as well as a pressure regulator to use.
  • the invention has for its object to provide a device for refrigeration as a compact unit, the performance of which can be predetermined by the generation of a defined natural circulation for the refrigerant.
  • the solution to this problem by the invention is characterized in that the heat exchanger surface of the plate heat exchanger is integrated in the steam drum designed as a pressure-resistant housing in such a way that both the supply nozzle and the discharge nozzle on one side and a deflection chamber for the coolant flowing horizontally through the plate heat exchanger arranged on the other side outside the housing of the steam drum and defined between the two side walls of the plate heat exchanger and the parallel housing walls of the steam drum drop channels are formed for the refrigerant circulated by gravity in natural circulation.
  • the combination of evaporator and steam drum according to the invention results not only in a space-saving construction, but also in the arrangement the heat exchanger surfaces of the evaporator in the liquid space Steam drum an evaporation process in natural circulation, in which the liquid Refrigerant enters the plate heat exchanger from below and as a gaseous one Refrigerant emerges from the top of the plate heat exchanger, but not evaporated refrigerant through integrated drop channels through the side walls of the Evaporator and the steam drum are formed as a result of Difference in density due to gravity flows down.
  • the way emerging natural circulation of the refrigerant and thus also the performance of the Device are influenced by the free cross section of the fall channels.
  • a Another decisive advantage of the invention is the fact that any Leakage of the plate heat exchanger with regard to the refrigerant through the Arrangement of the heat exchanger surfaces in the liquid space of the steam drum are unproblematic and do not cause refrigerant to leak into the Atmosphere.
  • a droplet separator can be located in the steam chamber of the steam drum be arranged.
  • the steam drum with a curved bottom can be arranged below the plate heat exchanger be the volume of the liquid space or the filling quantity of the Reduce refrigerant.
  • the device to generate only the steam drum 1 to recognize the consists of a pressure-resistant housing with an inlet connection 2 for the refrigerant consisting of a liquid-vapor mixture and with a steam nozzle 3 for the exit of the vaporous refrigerant is.
  • a droplet separator in the steam chamber in both exemplary embodiments 4 is arranged.
  • the welded Plate heat exchanger 5 designed heat exchanger surface of the evaporator.
  • the illustrated embodiment is an im Cross-countercurrent operated plate heat exchanger 5, the liquid Refrigerant from below in vertically upward channels of the Plate heat exchanger 5 occurs and partially evaporates, so that at the top of the plate heat exchanger 5 gaseous refrigerant from the Plate heat exchanger 5 emerges and into the steam space of the steam drum 1 reached.
  • the liquid refrigerant is used here (as in particular in FIG. 2 and 4) in natural circulation by gravity in Liquid space of the steam drum 1 circulated. This revolution will caused by drop channels 10 through the side walls of the evaporator and the steam drum are formed.
  • the plate heat exchanger 5 is a refrigerant via a supply nozzle 6 fed, preferably a water-brine mixture. This coolant arrives after flowing through the plate heat exchanger 5 in the horizontal direction into a deflection chamber 8, from which the refrigerant again in the opposite Direction flows through the plate heat exchanger 5 before it leaves through a discharge nozzle 7. By the evaporation of the refrigerant in the plate heat exchanger 5, heat is extracted from the refrigerant.
  • the steam drum 1 While in the embodiment of Figures 1 and 2, the steam drum 1 is designed with a flat bottom, the steam drum 1 has after the embodiment of Figures 3 and 4 an outwardly curved Bottom, which results in an enlarged liquid space. For that To reduce volume are in the embodiment in the lower part of the Steam drum 1 displacement body 9 arranged.
