    摘要: In a refrigeration unit including a variable performance compressor driven by an inverter motor, a sensor is configured to detect a physical amount corresponding to a refrigerant pressure on the high-pressure side of a refrigerant circuit. A measured value of the physical amount is compared with a first reference value corresponding to a first predetermined pressure of the refrigerant and a second reference value corresponding to a second predetermined pressure lower than the first predetermined pressure. A protective operation can start if the comparison result indicates that an actual refrigerant pressure is higher than the first predetermined pressure. The performance of the compressor can be gradually lowered if the comparison result indicates that an actual refrigerant pressure is between the first predetermined pressure and the second predetermined pressure.

    摘要: The liquid refrigerant from the compressor 20 and the condenser 21 is alternately supplied to the cooling device for the freezing room 27F and the evaporator for the refrigeration room 27R through the three-way valve 24, so that the freezing room and the refrigeration room are alternately cooled. Here, the ratio of the refrigerant supply time to each evaporator is controlled based not on a deviation between a target temperature set for each storage room and an actual storage room temperature measured in each storage room, but on an integrated value obtained by integrating the difference of these deviations. In a cooling storage, in which from one compressor a refrigerant is selectively supplied to multiple evaporators respectively disposed in multiple storage rooms of varied thermal loads, a one-storage room cooling mode is prevented from being unnecessarily switched to a alternate cooling mode.

An freezing apparatus (10) has a compressor (11) driven by a motor (16), circulating refrigerant discharged from the compressor (11) through a condenser (12), a dryer (13), a constant pressure expansion valve (14), and an evaporator (15) provided on the outer peripheral surface of the freezing cylinder (21). At the outlet of the evaporator (15) there is provided a temperature sensor (41) for sensing refrigerant temperature. A controller (42) controls the rotational speed of the motor (16) through an inverter circuit (43) such that the sensed refrigerant temperature is equal to a specified refrigerant temperature, allowing the freezing apparatus (10) to keep ice-making performance thereof. As a result, the auger type ice making machine can keep ice-making performance regardless of changes in ambient temperature or water temperature, securing stable ice generation and consistent quality of ice.

    摘要: An electric motor 25 for driving a compressor 21 that composes a refrigerating cycle is speed-controlled by an inverter circuit 31. When an inside temperature Tx detected by an inside temperature sensor 35 is not less than a predetermined temperature (for example, 5° C. in the case of a refrigerator and −18 C in the case of a freezer), a microcomputer 34 suppresses the rotational speed of the electric motor 25 via the inverter circuit 31 to thereby restrict current flowing through the electric motor 25 and a power circuit 40. Accordingly, great current does not flow through the electric motor 25 upon the start of the operation in a refrigerator or a freezer. Further, in this case, the rotational speed of the electric motor 25 is controlled to be increased as the inside temperature Tx becomes lower, whereby the cooling speed of the inside 10 is increased with the current flowing through the electric motor 25 prevented from increasing.

    摘要: A liquid refrigerant from a compressor and a condenser is alternately supplied to a cooling device for the freezing room 27F and an evaporator for refrigeration room through a three-way valve, so as to conduct the cooling of a freezing room and a refrigeration room. When the thermal load condition of a refrigerating cycle is light, the three-way valve switches to the “F side opened-state” after the compressor is stopped, and thereby conducting pressure balancing, without the liquid refrigerant flowing into the evaporator for refrigeration room. A cooling storage, wherein from one compressor a refrigerant is selectively supplied to multiple evaporators, is constituted so as to prevent one evaporator side from becoming a supercooled state, and furthermore, quickly conduct pressure balancing after stop of the compressor.
