INTERMEDIATE COOLING AGGREGATE IN A COOLING AND FREEZING PLANT

摘要

The present invention relates to a device for controlling the supply of oil to a cooling and freezing plant which includes a number of freezing compressors (14-17) and a number of cooling compressors (26-31), whereby the cooling medium preferably is of a type wherein oil is mixed with or floating on top of cooling medium liquid. In order to provide effective cooling of cooling medium vapour from the freezing compressors and simultaneously effective oil separation in the one and same device, the intermediate cooling aggregate (62) includes an oil separator (66) which is adapted to separate oil and cooling medium from each other by spraying an incoming oil and cooling medium mixture against surfaces along which oil may flow downwards and cooling medium depart upwards.
