When mobile switching valve 26 along R direction (along the refrigerating chamber direction) when opening, cold-producing medium circulates under the refrigerating chamber operator scheme, that is, press the sequential loop of compressor 20, condenser 22, heat pipe 24, flow switching valve 26, refrigerating chamber expansion gear 30, refrigerator evaporator 34 and compressor 20.
Therefore, the cold-producing medium that is in the HTHP gaseous state of discharging from compressor 20 is condensed into high-pressure liquid by condenser 22, introduces in the switching valve 26 that flows via heat pipe 24 subsequently.
Here, in mobile switching valve 26, because the passage along refrigerating chamber 14 sides of R direction is opened, then carry out the operation of refrigerating chamber 14, the cold-producing medium of wherein introducing in the switching valve 26 that flows is introduced refrigerator evaporator 34 by refrigerating chamber expansion gear 30, with refrigerated compartment 14, return compressor 20 (operation 106) subsequently.
When refrigerating chamber 14 is cooled under the refrigerating chamber operator scheme along with above-mentioned flow of refrigerant, can not produce the deficiency of cold-producing medium.
As mentioned above, parallel circulation is carried out in the following sequence: carry out the operation of operation, refrigerant-recovery operation and the refrigerating chamber 14 of refrigerating chamber 12 under the situation that compressor 20 cuts out, so that carry out the operation of refrigerating chamber 12 and refrigerating chamber 14 independently.Subsequently, judge that whether the compressor condition of closing satisfies (operation 108), and if judge that the compressor condition of closing satisfies, then compressor 20 cuts out (operation 110), and parallel cycling is finished.
As being apparent that according to foregoing description, in method of operating according to a kind of refrigerator of embodiment and this refrigerator of control, evaporimeter is installed in respectively in each of refrigerating chamber and refrigerating chamber, and, when refrigerator begins to operate, at first carry out the operation of refrigerating chamber, to adopt triple valve conversion coolant channel in parallel circulation, so that carry out the operation of refrigerating chamber and refrigerating chamber independently, realize energy-conservation thus.And, omitted the check-valves that is used to prevent the refrigerant flow direction freezer evaporator, realize the reduction of manufacturing cost thus, and shorten the operation necessary refrigerant-recovery operating time of refrigerating chamber.
