  • heat exchangers are carried out with a package of a plurality of pairs of round heat transfer plates that are pressure stable in the container.
  • the container must have at least one sufficiently stable flat end plate to support the package of round heat transfer plates and to be able to absorb the high pressure acting on them.
  • heat exchangers can be operated with full or partial flooding, as well as single or multiple tanks.
  • Refrigeration and air conditioning systems have in the refrigerant circuit in addition to the heat exchanger a subordinate this downstream, separate container as a liquid separator and a compressor, which are connected to each other via pipes on.
  • the droplets entrained in the evaporation of a refrigerant on the heat transfer plates are separated from the gas phase in a known manner. This deposition is necessary so that no liquid can with the liquid separator on ⁇ associated compressor to re-liquefy the refrigerant from the subsequently be sucked in the form of drops, otherwise the compressor may be damaged.
  • the object of the invention is to develop a structural unit comprising a heat exchanger with a plate heat exchanger and a liquid separator for separating droplets from vaporized refrigerant, in particular for refrigeration and air-conditioning systems, which saves space, material and refrigerant as well as being compact.

Abstract

L'invention concerne une unité modulaire comprenant un échangeur de chaleur et un éliminateur de gouttelettes pour éliminer des gouttelettes contenues dans un agent réfrigérant vaporisé, en particulier pour des installations de réfrigération et de conditionnement d'air, qui est de structure compacte. Selon l'invention, dans le réservoir sous pression (1) dans lequel sont montées de plaques de transfert de chaleur (2) dans la zone inférieure et dans lequel l'agencement des plaques de transfert de chaleur (2) dans la zone inférieure permet de créer au-dessus desdites plaques de transfert de chaleur (2) une zone supérieure servant d'espace pour éliminer les gouttelettes contenues dans l'agent réfrigérant vaporisé, les plaques de transfert de chaleur sont disposées sensiblement parallèles à l'axe longitudinal du réservoir sous pression.
