Abstract

In a refrigerating unit with a cooling evaporator (16) in a cooling chamber (12) and a freezing evaporator (18) in a freezing chamber (14) a common compressor (20) is arranged via a switchable valve (22) to force eithr refrigerant in proper order through the cooling evaporator (16) and the freezing evaporator (18) or only through the freezing evaporator (18). A means (28) is arranged on the cooling evaporator (16) to sense its temperature, the means (28) controlling that refrigerant is supplied tothe cooling evaporator (16) when the temperature goes above a certain higher value which allows the cooling evaporator to defrost and controlling that the supply of refrigerant to the cooling evaporator (16) is cut off when the temperature goes below a certain lower value which ensures that the cooling chamber gets a sufficient cooling capacity. To prevent goods in the cooling chamber (12) from freezing when freezing of goods takes place in the freezing chamber (14) a heat-insulating insert (30) is arranged between the means (28) and the cooling evaporator (16).
