Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce the load of a compressor without haling the operation of a fan by changing over from a small capacity running capacitor to a large capacity running capacitor only for a predetermined time when a temperature sensor of a condenser detects that the detected value exceeds an upper setting value. SOLUTION: When power is switched on, a compressor 4, a fan 7 and PSC fan motor 26 start operation with a small capacity running capacitor 28 and it is determined whether or not both detected temperature of the room temperature sensor 14 and the detected temperature of the freezer compartment sensor exceed the predetermined values. In the case when they exceed the upper limit temperature, it is necessary to change over to a large capacity running capacitor 29 since an input load to the compressor 4 is increased. It is also necessary to change over to a small capacity running condenser 28 after a predetermined time elapses.

Abstract: PROBLEM TO BE SOLVED: To improve the operational reliability of a compressor when the power supply is switched on and to shorten the time required for the refrigerator temperature during a power failure to return to a prescribed temperature. SOLUTION: In a refrigerator, a compressor 4 and a blower fan 7 are turned on and an on-off control of a damper device 10 are started immediately after the power supply is switched on. When both of the temperature DA of a condenser temperature sensor 23 and the temperature DF of a freezing chamber temperature sensor 9 are a set temperature Dmax or above at this time and further when the temperature DC of the condenser temperature sensor 23 is an upper-limit set value DCmax or above at the time point after a prescribed time ΔT1 passes from that time, the damper device 10 is held in a closed state forcedly only for a prescribed time ΔT2 thereafter and a normal control is conducted after this closed state passes.

Abstract: PURPOSE:To raise reliability of a compressor by feeding back a refrigerant to a compressor as a complete gas refrigerant even starting after defrosting by providing accumulators between an evaporator and the compressor and in the compressor. CONSTITUTION:A refrigerator includes a compressor 1 for compressing a refrigerant, a condenser 2 for cooling a refrigerant for condensation thereof, a capillary tube 3 for reducing the pressure of a liquid refrigerant, and an evaporator 4 for vaporizing a liquid refrigerant. A suction accumulator 5 is located between the evaporator 4 and the compressor 1, and a compressor accumulator 8 is located in the compressor l. Upon defrosting a liquid refrigerant is vaporized by the evaporator 4 and pressure is raised in a suction line 7 so that the liquefied refrigerant is rendered to liquid separation in the suction accumulator 5. Further, upon the compressor 1 being started the liquid refrigerant thrusted into the compressor 1 is phase-changed to a gas refrigerant owing to abrupt expansion of the liquid refrigerant in the compressor accumulator 8 and is fed back to the compressor 1.

Abstract: PROBLEM TO BE SOLVED: To easily use a changeover room, and to improve an accommodation property by providing the changeover room that can be changed as a freezer, a low-temperature room, and a cold room, and by providing the damper device of the changeover room for controlling the supply of chill to the changeover room in the connection duct of the changeover room being provided on the back surface of a vegetable room. SOLUTION: Chill cooled by a cooling room 23 is ventilated to a changeover room 21 by a fan device 24 via a connection duct 25 of the chageover room and a discharge duct 26, a proper amount of chill is sent by a damper device 27 of the changeover room being provided on the back surface of a vegetable room 17 for maintaining suitable temperature as a freezer, a low-temperature room, and a cold room. In this manner, the connection duct 25 of the changeover room with the damper device 27 of the changeover room is provided on the back surface of the vegetable room 17, thus dispensing with the provision of the connection duct 25 of the changeover room on the back surface of the changeover room 21, increasing volume inside the changeover room 21, and improving the usability and its accommodation property of the changeover room 21.

Abstract: PROBLEM TO BE SOLVED: To reduce load on a compressor applied at the time of power being tuned on, when outdoor temperature and inside temperature of the refrigerator are high. SOLUTION: When both the temperature detected by a chamber-temperature sensor and the outdoor temperature are at least a predetermined temperature, (i.e., in the case power is turned on at uncooled time of both the outdoor and chamber temperatures being high), a flow-rate of refrigerant passing through a refrigerant flow-rate variation device 26 is controlled (forcedly decrease the refrigerant circulation amount) by the device 26 for a predetermined time, after the lapse of predetermined time from turning-on of the power). Thus, rapid discharge-pressure rise of the compressor 18 is restrained to reduce the load on the compressor 18, and its reliability can be enhanced (to prolong the service life of the compressor 18 is attained).
