  • REFRIGERATION CYCLE DEVICE
    Publication number: 20220034561
    Abstract: A refrigeration cycle device includes a refrigerant circuit switching device. The refrigerant circuit switching device is configured to switch among at least a first circuit and a second circuit. The first circuit conducts refrigerant, which is outputted from a heat releasing device, to a liquid storage and conducts the refrigerant, which is outputted from the liquid storage, to a first depressurizing device and conducts the refrigerant, which is depressurized by the first depressurizing device, to an external heat exchanger. The second circuit conducts the refrigerant, which is outputted from the external heat exchanger, to the liquid storage and conducts the refrigerant, which is outputted from the liquid storage, to a second depressurizing device and conducts the refrigerant, which is depressurized by the second depressurizing device, to an evaporating device.

  • Manufacturing method of air passage switching door
    Patent number: 6872348
    Abstract: An air passage switching system includes a switching door that is disposed rotatably in a case to open and close an air passage of the case. The switching door includes a door body, a rotation shaft provided in the door body, and a seal member made of an elastomer and adhering to an outer peripheral portion of the door body. The seal member contacts on a sealing surface of the case when the switching door closes the air passage. A plurality of recess portions are formed on the outer peripheral portion of the door body to be arranged in an outer peripheral direction. Thus, adhesion between the door body and the seal member can be strengthened.
