    Abstract: An adsorption core has (i) a heat medium tube in which a heat medium flows and (ii) an adsorption agent that adsorbs a fluid in a vapor phase outside of the heat medium tube when being cooled by the heat medium and desorbs the absorbed fluid when being heated. The heat medium tube has (i) a core member that is made of metal having a higher hardness with respect to copper and (ii) a covering layer that is made of copper and covers an outer surface of the core member. A sintered body of a copper powder and the adsorption agent is provided in a peripheral portion of the heat medium tube.

    Abstract: A motor-driven vehicle includes an electric motor, a power storage device, a control device, and a refrigerant circuit. The refrigerant circuit has a compressor, an indoor heat exchanger, an expansion valve, and an outdoor heat exchanger. The indoor heat exchanger exchanges heat with the refrigerant compressed by the compressor. The refrigerant which passes through the indoor heat exchanger is decompressed by the expansion valve, and the outdoor heat exchanger exchanges heat with the decompressed refrigerant and allows the refrigerant to return to the compressor. When the remaining capacity of the power storage device is equal to or more than a predetermined value, the control device operates the compressor and decreases a passing-through air volume of a first air guide device that controls a passing-through air volume of the outdoor heat exchanger.
