    Abstract: PROBLEM TO BE SOLVED: To prevent a temperature within a freezing chamber from being increased when a compressor is started to be energized in a refrigerator. SOLUTION: A freezing chamber 1 is comprised of, within a cooler chamber 10, a refrigerator fan 6, a freezing chamber air blowing-out port 16 for feeding out cold air to a freezing chamber 1, a refrigerator chamber air blowing-out port 17 for feeding out cold air to a refrigerator chamber 2 and an air blowing- out port changing-over means 18 for changing-over the air blowing-out port. Cooling of the cooler chamber 10 is carried out before starting of cooling operation at the freezing chamber 1. When a cooling at the freezing chamber 1 is started, air in the cooler chamber 10 having a higher temperature than that of the freezing chamber 1 is restricted from being flowed into the freezer chamber 1 and then the temperature in the freezer chamber 1 is prevented from being increased.

    Abstract: PROBLEM TO BE SOLVED: To improve a cooling efficiency and an ability to keep food fresh by elevating a humidity in a refrigerating chamber of a refrigerator which includes a freezing chamber and the refrigerating chamber. SOLUTION: A freezing refrigerator comprises a cooling system and a plurality of cooler fans A9a and B15 which cool respective rooms, wherein the cooling system is constructed such that one connecting line which connects a freezing chamber evaporator 7a with freezing chamber pressure reducing means and another connecting line which connects a refrigerating chamber evaporator 11, refrigerating chamber pressure reducing means and a closure valve with each other are branched off in parallel and are connected with a suction line, an ability controllable compressor 6a and a condenser 17 in series. Due to such a construction, it becomes possible to supply cool air to each room in a proper amount necessary for cooling the room so that an efficient cooling can be realized by restricting an influence to other rooms. Furthermore, in the refrigerating chamber 3, the ability controllable compressor 6a, the condenser 17, the closure valve and the cooler fan B15 are operated in response to an indoor condition by system control means so that a humidity can be elevated easily.

    Abstract: PROBLEM TO BE SOLVED: To prevent a temperature within a freezing chamber from being increased due to operation of a refrigerator fan when a temperature of an evaporator is high as compared with temperature of sucked air in a cooling device at the time of starting an operation of a compressor. SOLUTION: There are provided an evaporator temperature sensing means 17 for sensing a temperature of an evaporator 4 and a suction air temperature sensing means 18 for sensing a temperature of a cold air suction port 16. At the time of starting an operation of a compressor 3, only when a temperature signal detected by the evaporator temperature sensing means 17 is higher than a temperature signal detected by the suction air temperature sensing means 18, a cooling control means 9 controls stopping of the refrigerator fan 5 in such a way that the air is not circulated to the freezing chamber 1.

    Abstract: PROBLEM TO BE SOLVED: To improve a food preserving condition of a freezing refrigerator having a freezing chamber and a refrigerating chamber by elevating a humidity of the refrigerating chamber while elevating a cold-air blow-off temperature of the refrigerator. SOLUTION: A freezing refrigerator comprises a refrigerating cycle for refrigerating, a refrigerating cycle for freezing, and switching means which switches these two cycles, wherein the refrigerating cycle for refrigerating is formed by connecting a compressor 27, a condenser 28, a first throttling device 29, an evaporator 25 for refrigerating, a second throttling device 30, and an evaporator 22 for freezing in series, while the refrigerating cycle for freezing is formed by connecting the compressor 27, the condenser 28, a third throttling device 31, and the evaporator 22 in series. Due to such a construction, during a freezing chamber refrigerating operation, the refrigerating is carried out using the refrigerating cycle for freezing so as to refrigerate at a low evaporating temperature, while during the refrigerating chamber refrigerating operation, the refrigerating is carried out using the refrigerating cycle for refrigerating so as to operate at a high evaporating temperature so that a blow-off cold-air temperature is elevated and a humidity in the refrigerating chamber is held high even if an amount of food accommodated in the refrigerating chamber is small.

    Abstract: PROBLEM TO BE SOLVED: To prevent foodstuffs in a refrigerator chamber from being frozen or icing within the refrigerator chamber, reduce drying in the refrigerator chamber and improve keeping a freshness of the foodstuffs in the refrigerator at a low cost. SOLUTION: One evaporator 19 is partitioned by a partition member 20 into a first evaporator region 21 and a second evaporator region 22. A cooling air passage 23 of a freezing chamber includes a first evaporator region 21 and a freezing chamber cold air circulating means 24. With such an arrangement as above, air in the freezing chamber and air in the refrigerator chamber are cooled independently from each other and each of suitable temperatures of the discharged air can be attained, so that the temperature within each of the chambers can be made uniform at a low cost.

    Abstract: PROBLEM TO BE SOLVED: To sane space of an ineffective volume of a cold storage chamber and to reduce noise of a fan of a chilled gas circulating means for cold storage. SOLUTION: An evaporator 21 for cold storage integrally molded with a heat exchanger for a cold storage chamber 2 and an arbitrary wall for constituting a chilled gas circulating duct 24 is provided to reduce a disposing space of the evaporator 21. A constitution of the duct 24 can be simplified. Further, at the time of normal cooling, the chamber 2 is cooled therein to a predetermined temperature by a natural convection by means of heat exchanging via the evaporator 24 as a rule, and hence noise of a fan of a chilled gas circulating means 25 for cold storage can be reduced.
