Method for controlling operation of cooling system having two evaporators

摘要

Method for controlling operation of a refrigerator having two evaporators 5,7 , in which a flow control valve 3 is controlled for selectively carrying out an F-cycle for making refrigerant to flow from a compressor 1 to an F-evaporator 5 for cooling down a freezing chamber 8 or a R-cycle for making the refrigerant to flow to a R-evaporator 7 for cooling down a refrigerating chamber 9, including the steps of (a) if one of temperatures of the freezing chamber 8 and the refrigerating chamber 9 meets an upper limit temperature of the freezing chamber 8 or the refrigerating chamber 9 relevant to the one of temperatures preset at a controlling part, putting the compressor 1 into operation and controlling the flow control valve 3 for carrying out the F-cycle or the R-cycle relevant to the one of temperatures, (b) if the one of temperatures meets a lower limit temperature of the freezing chamber 8 or the refrigerating chamber 9 relevant to the one of temperatures preset at the controlling part as the F-cycle or the R-cycle relevant to the one of temperatures is progressed, controlling the flow control valve 3 for shifting from the F-cycle or the R-cycle relevant to the one of the temperatures to the F-cycle or the R-cycle not relevant to the one of temperatures, and (c) if the other one of temperatures of the freezing chamber 8 and the refrigerating chamber 9 meets the lower limit temperature relevant to the other one of temperatures as the F-cycle or the R-cycle relevant to the other one of temperatures is progressed, stopping the compressor 1.
