An evaporator for a refrigeration system is formed as a heat exchanger consisting of a horizontal container (1) with longitudinal tubes (2) traversed by a heat transfer medium, for example water or brine. The container is provided with collection chambers (4, 5) for the tubes at the ends of the inlet and outlet of the heat transfer medium. The liquid refrigerant is passed in through an inlet (8) at one end of the container and is discharged through an outlet (9) at the top of the container at the other end thereof. Somewhere in the centre of the container, the container is divided into two parts by means of a vertical partition (10) so that the first part of the container operates as a so-called flowing evaporator, in which the refrigerant boils up around the tubes. The vertical partition operates as a spillway for the boiling liquid refrigerant, of which a certain part, by means of the boiling, flows over the upper edge of the partition. In this way it is ensured that oil in the refrigerant is forwarded with the evaporated refrigerant back to the compressor. <IMAGE> |
