摘要： A heat exchange system for realizing an adequate heat exchange among a plural type of fluids uses a refrigerant radiator and a radiator which are combined to have one unit for enabling heat exchange between a refrigerant and a coolant, and decreases an inflow amount of the coolant flowing into the radiator when coolant temperature of the coolant flowing into the radiator is equal to or higher than a second standard temperature, which is set to be lower than a temperature of the refrigerant flowing into the refrigerant radiator, and is equal to or lower than a predetermined first standard temperature. In such manner, heat from the refrigerant is effectively transferred to an outside air by reducing an unwanted heat exchange between the refrigerant and the outside air.

摘要： In a heat pump cycle, refrigerant tubes of an outdoor heat exchanger serving as an evaporator for evaporating refrigerant, and cooling fluid tubes of a radiator for dissipating heat from a coolant of an electric motor for traveling serving as an external heat source are bonded to the same outer fins. The heat contained in the coolant flowing through the cooling fluid tubes can be transferred to the refrigerant tubes of the outdoor heat exchanger via the outer fins. Thus, in the defrosting operation which involves defrosting the outdoor heat exchanger by flowing the coolant through the radiator, the loss in transfer of the heat contained in the coolant to the outdoor heat exchanger can be suppressed, and the heat supplied from the electric motor for traveling can be effectively used for defrosting the outdoor heat exchanger.

摘要： A composite heat exchanger includes a first heat exchanger configured to exchange heat between feed air and a refrigerant, and a second heat exchanger configured to exchange heat between the feed air and engine coolant. The composite heat exchanger is integrated so as to enable heat transfer between discharge refrigerant flowing through the first heat exchanger and the coolant flowing through the second heat exchanger. Furthermore, the composite heat exchanger is configured to change an amount of the heat exchanged among the feed air, the discharge refrigerant and the coolant in the composite heat exchanger by changing at least one of a volume of the feed air, a refrigerant discharge capacity of the compression mechanism, and an inflow amount of the heat medium.

摘要： A heat pump cycle includes a compressor having a suction port and a discharge port, a heating heat exchanger which heats air, a gas-liquid separator, and a cooling heat exchanger which cools air upstream of the heating heat exchanger in an air flow direction. The heat pump cycle further includes an intermediate pressure passage which guides gas refrigerant from the gas-liquid separator to the suction port. A variable open-close portion opens the intermediate pressure passage and decompresses the gas refrigerant in the intermediate pressure passage, so that the gas refrigerant is introduced into the suction port when a bypass dehumidifying-heating mode is selected as a dehumidifying-heating mode in which the air having been heated in the heating heat exchanger becomes equal to or higher than air in an air-conditioning target space in temperature.
