Abstract (en)
[origin: WO2007115879A1] The invention relates to a method for operating a refrigerating device comprising a refrigerating circuit (15; 25; 35; 45) equipped with two evaporators (16, 17) which are arranged in a parallel manner in relation to each other and which cool refrigerating compartments (12, 13) that are thermally separated from each other and that have different temperatures, and also a refrigerating compressor (22) with which both evaporators (16, 17) can be supplied separately with a coolant. According to the invention, when a first compartment (12) requires a coolant, the evaporator (17) of the second compartment is initially supplied with a coolant, in a preparation step, and then the coolant circuit is closed to the evaporator (17) of the second compartment (13), and then only the evaporator (16) of the first compartment (12) is supplied with the coolant. In said preparation step, fluid coolant which is enriched in the evaporator of the second refrigerating compartment is flushed out such that it can be reused in the evaporator of the first refrigerating compartment. As a result, the coolant is displaced towards the evaporator of the coolest of the two refrigerating compartments, said displacement can be produced in the stationary phase of the coolant compressor and can be achieved in a simple and economical manner.
