Abstract: A refrigerator has a refrigerator compartment, a freezer compartment, and a low-temperature storage chamber formed in the refrigerator compartment and having a temperature lower than that of the refrigerator compartment. The refrigerator includes a compressor, a condenser, a first throttling device, a channel control valve, a refrigerator cooling unit, and a freezer cooling unit connected in series to form a refrigerating cycle. The refrigerator cooling unit and the freezer cooling unit are accommodated in the refrigerator compartment and the freezer compartment, respectively. The refrigerator also includes a second throttling device connected in parallel with the refrigerator cooling unit, a first air fan for sending cold air heat-exchanged by the refrigerator cooling unit to the refrigerator compartment, a second air fan for sending cold air heat-exchanged by the freezer cooling unit to the freezer compartment, a suction duct for introducing air inside the refrigerator compartment to the refrigerator cooling unit, a discharge duct for introducing air cooled by the refrigerator cooling unit into the refrigerator compartment and into the low-temperature storage chamber, and an electrically-operated damper accommodated in the discharge damper. When the electrically-operated damper is opened, an amount of air to be introduced into the low-temperature storage chamber is greater than an amount of air to be introduced into the refrigerator compartment.

Abstract: PURPOSE:To facilitate the control of a cooling fan by guiding a detecting value from an outside air temperature sensor to a controlling microcomputer, comparing it with a prescribed set value preset to the controlling microcomputer, breaking a delay timer function when the detecting value exceeds the get value and driving the cooling fan. CONSTITUTION:A controlling microcomputer 5 fetches a detecting value from an outside air temperature sensor 7 upon start of a compressor 1, converts it by an A/D converter 8 and compares the converted value with respective set values preset to the controlling microcomputer 5. When the set value exceeds the detecting value form the outside air temperature sensor 7, a delay timer 9 is cancelled and a cooling fan is driven synchronizing with starting of the compressor 1. When the set value is lower than the detecting value, the cooling fan 3 is not driven. Accordingly, the compressor 1 can be easily and effciently cooled based on an outside temperature and a wasteful power consumption can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To improve safety of an illuminating device of a refrigerator in the case of using a combustible refrigerant. SOLUTION: In this illuminating device 21, a in-storage lamp 29 and a socket 28 are integrated with each other, and a connecting part (a pin 26) to a lead wire 24 is an insert type using a connector 25. The occurrence of spark in lighting due to looseness of a connecting part of the in-storage lamp 29 and the lead wire is prevented to eliminate an ignition source. Accordingly, even if a combustible refrigerant leaks in the storage in the refrigerator using the combustible refrigerant in refrigerating cycle, unsafe condition can be prevented.

Abstract: PROBLEM TO BE SOLVED: To achieve a curtailing of power consumption and a lowering of noise by improving a heat radiation effect in a natural radiation system concerning a radiation system of a refrigerator to achieve a shift to a natural radiation system from the radiation system of a large refrigerator employing a heat radiation with the conventional force fan. SOLUTION: This refrigerator comprises the body 1 of a refrigerator, a back 4 of the refrigerator, a side part ventilation path 5, a heat radiation pipe 14 provided on the back 4 of the refrigerator proximity to the side part ventilation path 5, a machine room 7 and a wall and heat of the machine room 7 is discharged above the body l of the refrigerator passing through the side part ventilation path 5 by heat transmission effect attributed to a draft effect by heat radiation of the radiation pipe 14. This improves radiation effect by a natural radiation system thereby achieving a curtailing of the power consumption and a lowering of noise.

Abstract: PROBLEM TO BE SOLVED: To prevent an amount of a refrigerant from becoming excessive in a refrigerator having a freezing function when the temperature of a front face portion of a partition formed in a front opening portion becomes higher than a dew generating temperature. SOLUTION: A dew generating temperature is calculated based on measured results of an ambient temperature measuring device 22 and an ambient humidity measuring device 23 of a refrigerator body 21 having a freezing function. The calculated dew generating temperature is compared with temperatures measured by temperature measuring devices 24, 25, 26 on a front face portion of a partition. In case that the measured temperatures are higher than the dew generating temperature, a refrigerant is made to circulate through a bypass condenser 31 so as to reduce a heat absorbing load of the inside of the refrigerator thus enabling a reduction of a power consumption.

Abstract: PROBLEM TO BE SOLVED: To reduce the operation sound at the time of a blower for a cold storage room and a blower for freezing room being driven at the same time, in a cooling system where the cold storage room and the freezing room are severally independent. SOLUTION: When a blower 4 for a cold storage room and a blower 7 for a freezing room 7 operate at the same time, the blower 7 for a freezing room is operated at a speed lower than its usual speed being set in advance, and when the blower 4 for a cold storage room stops its operation, the blower 7 for a freezing room is operated at the usual speed. Accordingly, the operation sound of the blower can be lowered while keeping the cooling capacity.

Abstract: PROBLEM TO BE SOLVED: To improve the operational reliability of a compressor when the power supply is turned on and also 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 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 blower fan 7 is held in a state of low-speed operation only for a prescribed time ΔT2 thereafter and a normal control is conducted after this state of low-speed operation passes.
