Abstract

At least one radiator (1) is connected in series with at least one evaporator (2) of a mechanical refrigeration circuit. The pump unit (3) pref. consists of a pair of pumps (4,5) in parallel and capable of functioning in alternation. The radiator is provided with a branch pipe (6) which leads to a three-way valve (7) situated between the radiator and evaporator. The circuit may also include an expansion vessel (10). A current of external atmospheric air (11), blown by one or more fans, comes into contact with the radiator and then with the air-cooled condenser (9) of the mechanical refrigeration circuit which includes a compressor (17) an expansion valve (18) and the evaporator (2) connected with the appropriate piping.
