    Abstract: A refrigeration cycle device has a compressor, a radiator, an auxiliary heat exchanger, a decompressor, an evaporator, and an interior heat exchanger. The auxiliary heat exchanger performs a heat exchange between refrigerant and air and causes the refrigerant to radiate heat. The evaporator performs a heat exchange between air and refrigerant after being decompressed in the decompressor before the air is heated in the auxiliary heat exchanger. The interior heat exchanger has a first heat exchanging portion and a second heat exchanging portion and performs a heat exchange between refrigerant flowing in the first heat exchanging portion and refrigerant flowing in the second heat exchanging portion. The first heat exchanging portion is disposed in a refrigerant path between the radiator and the decompressor and is connected to the auxiliary heat exchanger in series. The second heat exchanging portion is disposed in a refrigerant path between the evaporator and the compressor.

    Abstract: A cold storage heat exchanger that exchanges heat with air flowing therearound includes: a refrigerant passage through which refrigerant flows; and a cold storage body housing a cold storage medium that exchanges heat with refrigerant flowing through the refrigerant passage and stores an amount of heat from the refrigerant. The cold storage medium includes: a low carbon number paraffin comprising at least one of C12 paraffin and C13 paraffin; and a high carbon number paraffin comprising at least one of C15 paraffin and C16 paraffin. A concentration of the high carbon number paraffin in the cold storage medium is higher than 60 percent by weight and lower than 100 percent by weight. A concentration of the low carbon number paraffin in the cold storage medium is higher than 0 percent by weight and lower than 40 percent by weight.

    Abstract: An air conditioner includes a first inlet-side inside/outside air switching part, a first outlet-side outside/inside air switching part, a second inlet-side inside/outside air switching part and a second outlet-side inside/outside air switching part. In a dehumidifying heating mode, the first outlet-side inside/outside air switching part makes a switch to a ventilation path that guides air having passed through a first heat exchange part into a space to be air-conditioned, and the second inlet-side inside/outside air switching part makes a switch to a ventilation path that guides outside air to a second heat exchange part. In a defrosting mode, the second inlet-side inside/outside air switching part makes a switch to a ventilation path that guides inside air to the second heat exchange part, and a flow rate of refrigerant flowing through the second heat exchange part is reduced more than in the dehumidifying heating mode.

    Abstract: A regenerative heat exchanger includes a refrigerant pipe, a regenerator, and an air passage fin. The air passage fin is disposed in an air passage defined outside of the refrigerant pipe and the regenerator, and is thermally connected with the regenerator directly or through the refrigerant pipe. At least one of the regenerator and the air passage fin is configured such that a thermal resistance between a part of a regenerative material located on an upstream side and air flowing through the air passage becomes larger than a thermal resistance between a part of the regenerative material located on a downstream side and air flowing through the air passage.

    Abstract: An air conditioner includes a circulation flow channel in which a refrigerant circulates, an evaporator provided in the circulation flow channel to cool air by heat exchange with the refrigerant passing through the circulation flow channel, a first cold storage unit provided in the evaporator at a position adjacent to a tube in which the refrigerant flows in the evaporator, and a second cold storage unit provided in the circulation flow channel at a position different from the evaporator. The first cold storage unit is configured to store therein a first cold storage material which changes in phase by the heat exchange with the refrigerant passing through the tube, and the second cold storage unit is configured to store therein a second cold storage material which changes in phase by the heat exchange with the refrigerant passing through the circulation flow channel.

    Abstract: A first header tank and a second header tank of a cold-storage heat exchanger are located away from each other. Refrigerant tubes include refrigerant passages through which the first header tank and the second header tank communicate with each other. The refrigerant tubes are spaced away from each other. Cold energy containers storing cold energy storage members are provided to close air passage portions defined between the refrigerant pipes. A region including the air passage portions are separated into a first region including a center part of the region and a second region that is remaining part of the region. A proportion of the cold energy containers in the second region is larger than that in the first region.
