摘要： Vehicle air conditioning device executes the dehumidifying mode in which a controller lets refrigerant discharged from compressor 2 radiate heat in radiator 4, decompresses the refrigerant from which heat has been radiated and then lets the refrigerant absorb heat in heat absorber 9 and outdoor heat exchanger 7, or lets the refrigerant discharged from compressor 2 radiate heat in radiator 4 and outdoor heat exchanger 7, decompresses the refrigerant from which heat has been radiated and then lets the refrigerant absorb heat in heat absorber 9. In the dehumidifying mode, the controller executes simple control to compare a target value of an index that is a basis of control of the outdoor expansion valve with an actual detected value and to change a valve position of the outdoor expansion valve from a magnitude relation between the value in an enlarging direction or a reducing direction as much as a constant value.

摘要： A refrigerating cycle apparatus includes: a compressor that compresses and discharges refrigerant; a radiator that makes the refrigerant discharged out of the compressor to radiate heat; a pressure reducing device that decompresses the refrigerant flowing out of the radiator; an evaporator that evaporates the refrigerant decompressed by the pressure reducing device; and a decompression control part that controls operation of the pressure reducing device. The decompression control part controls the operation of the pressure reducing device in a manner that a physical quantity which has correlation with a pressure of the refrigerant in the evaporator approaches a predetermined defrosting standard value when a time-priority defrosting mode is set.

摘要： A cooling device that can maintain or improve a cooling ability without being affected by fluctuation in an ambient temperature. Gas is supplied to a cooling target to cool the cooling target. A cooling device includes a cooling gas including gas having thermal conductivity higher than the thermal conductivity of the air, a partition wall that closes and stores the cooling target and the cooling gas and is capable of circulating the cooling gas, a cooling section that cools and circulates the cooling gas, a pressure determining section that determines the pressure of the cooling gas, and a cooling control section that controls the cooling section. The cooling control section causes the cooling section to change the pressure of the cooling gas and/or change the circulation speed of the cooling gas on the basis of a result of the determination of the pressure determining section.
