Abstract: A cold storage heat exchanger includes multiple refrigerant tubes, a cold storage container that is bonded to the refrigerant tube and defines a compartment receiving a cold storage material, and an inner fin arranged inside of the cold storage container. The cold storage container has a portion that stops and fixes the inner fin, and the cold storage container has a space where air is sealed. The space of the cold storage container is located at an upper side of the member that stops and fixes the inner fin. Accordingly, a stress applied to the cold storage container in the expansion of the cold storage material can be reduced.

Abstract: A refrigeration cycle device includes a flow path switching unit configured to determine whether an outside-air heat absorption unit is required to be defrosted. The flow path switching unit is further configured to: cause a heat medium to circulate separately between a first circulation circuit configured to cause the heat medium to circulate through a heat source and a second circulation circuit configured to cause the heat medium to circulate between an evaporation unit and the outside-air heat absorption unit, when it is determined that the outside-air heat absorption unit is not required to be defrosted; and switch a flow path of the heat medium to cause the heat medium in the first circulation circuit to circulate through the outside-air heat absorption unit, when it is determined that the outside-air heat absorption unit is required to be defrosted.

Abstract: A refrigeration cycle device includes: a compressor; a heat radiating unit that causes refrigerant to heat air supplied to a space inside a vehicle cabin; a decompression unit that decompresses the refrigerant; an outside air heat absorbing unit that causes the refrigerant to absorb heat from outside air; a waste heat absorbing unit that causes the refrigerant to absorb waste heat of a waste heat device; a shutter that opens and closes a passage for the outside air introduced into the outside air heat absorbing unit; and a control unit that closes the shutter when it is determined that an amount of waste heat of the waste heat device is larger than an amount of heat absorbed by the refrigerant in the outside air heat absorbing unit and the waste heat absorbing unit.

Abstract: A heat generator includes an electrode terminal, a heating element, an electrically conductive housing, and an insulator. The electrode terminal is stacked on the heating element in a stacking direction. The housing houses a stacked body formed of the heating element and the electrode terminal. The stacked body includes a pair of side wall surfaces each extending in the stacking direction, an element side end surface, and a terminal side end surface. The element side end surface is in close contact with the case inner wall surface. Both the terminal side end surface and the pair of side wall surfaces are entirely in close contact with the case inner wall through the insulator. The housing includes a pair of facing walls facing and extending along the pair of side wall surfaces to serve as a positioning member that restricts the heating element from moving in the intersecting direction.

Abstract: A cold storage heat exchanger includes multiple refrigerant tubes, a cold storage container, an inner fin, a cooling air passage and an air-side fin. The inner fin is arranged inside of the cold storage container. The cooling air passage, in which air flows to cool a space, is provided to contact a surface of the refrigerant tube on a side opposite to the cold storage container. The air-side fin is arranged in the cooling air passage and thermally connected to the refrigerant tube. The cold storage container includes multiple recess portions bonded to the inner fin, and multiple protrusion portions located on an outer side of the recess portions. The protrusion portions of the cold storage container are bonded to an outer surface of the refrigerant tube.

Abstract: A compressor module includes: an evaporator configured to evaporate a refrigerant of a vapor compression refrigeration cycle; a liquid storage configured to store the refrigerant in a liquid phase; a compressor configured to suction and compress the refrigerant; and a flow passage forming member to which the evaporator, the liquid storage and the compressor are installed. The flow passage forming member forms at least a portion of a flow passage of the refrigerant. The compressor is positioned on a lower side of the flow passage forming member, and the flow passage of the refrigerant includes a suction-side refrigerant flow passage, through which the refrigerant in a gas-phase to be suctioned into the compressor flows. The suction-side refrigerant flow passage has a rising portion that rises upward as the rising portion approaches the compressor.

Abstract: An air conditioner includes: a heat pump cycle including a compressor, a heating part and a low-temperature side water-refrigerant heat exchanger; a heat medium circuit; and a blower. In the air conditioner, when a heating capability of the heating part is increased by using the heat generated by the heat generating part, a heating preparation control is executed, in which a refrigerant discharge capability of the compressor is set to be equal to or less than a predetermined reference discharge capability and a blowing capability of the blower is set to be equal to or less than a predetermined reference blowing capability, until an inlet-side heat medium temperature of the heat medium flowing into the heat medium passage of the low-temperature side water-refrigerant heat exchanger becomes equal to or higher than a target heat medium temperature.

Abstract: An air conditioner for a vehicle includes a refrigeration cycle, a heating unit and a control unit. The refrigeration cycle includes an air-conditioning evaporator, a chilling evaporator, an air-conditioning side flow path, a detour flow path and an air-conditioning flow rate adjustment unit. The control unit includes a determination unit that determines whether a condensation condition is satisfied when a refrigerant is flowing through the chilling evaporator via the detour flow path in a state where an inflow of a refrigerant into the air-conditioning evaporator is prohibited. When the determination unit determines that the condensation condition is satisfied, the control unit controls the air-conditioning flow rate adjustment unit to allow an inflow of a refrigerant into the air-conditioning evaporator as a condensation suppression operation for suppressing condensation of a refrigerant in the air-conditioning evaporator.
