  • Publication number: 20230332774
    Abstract: A hot water supply device and a hot water supply system are provided. A controller actuates a circulation pump at a constant output and actuates a heating mechanism for heating by a combustion mechanism when an instantaneous hot water operation is started in response to a temperature drop of a fluid while hot water supply of a hot water supply tap is stopped, until a minimum drive time elapses. The minimum drive time is set based on a flow rate detection value of a flow rate detector under a condition that the circulation pump is actuated at a predetermined constant output and an instantaneous hot water circulation path is formed.

  • Patent number: 11785827
    Abstract: A display device that can switch between normal display and see-through display is provided. Visibility in see-through display is improved. A liquid crystal element overlaps with a light-emitting element. The light-emitting element, a transistor, and the like overlapping with the liquid crystal element transmit visible light. When the liquid crystal element blocks external light, an image is displayed with the light-emitting element. When the liquid crystal element transmits external light, an image displayed with the light-emitting element is superimposed on a transmission image through the liquid crystal element.

  • Patent number: 11247536
    Abstract: A vehicle air conditioner capable of making a determination that the dehumidification is unnecessary in a vehicle interior early to make a prompt transition from a dehumidifying mode to a heating mode and reduce power consumption is provided. A control device executes a heating mode to let a refrigerant discharged from a compressor 2 radiate heat in a radiator, decompress the refrigerant, and then let the refrigerant absorb heat in an outdoor heat exchanger 7, and a dehumidifying mode to let the refrigerant flow into the outdoor heat exchanger without flowing to the radiator to radiate heat therein, decompress the refrigerant, and then let the refrigerant absorb heat in a heat absorber 9 and let an auxiliary heater 23 generate heat. The control device shifts from the dehumidifying mode to the heating mode on the basis of the heat absorber suction air temperature Tevain being lowered more than a target heat absorber temperature TEO.

  • Patent number: 11203251
    Abstract: There is disclosed a vehicle air conditioning device which inhibits generation of noise in a solenoid valve 30 disposed on an inlet side of a radiator 4 and improves durability of the solenoid valve. A second operation mode is executed to shut off an outdoor expansion valve 6, close the solenoid valve 30, open a solenoid valve 40 and thereby send a refrigerant discharged from a compressor 2 through a bypass pipe 35 to an outdoor heat exchanger 7. When a first operation mode to open the solenoid valve 30 and close the solenoid valve 40 and thereby send the refrigerant to the radiator 4 is shifted to the second operation mode, a controller opens the solenoid valve 30 at a timing to stop the compressor 2.

  • Patent number: 11192428
    Abstract: A vehicle air-conditioning device is provided which is capable of eliminating or suppressing vibration and noise generated due to the application of a counterpressure to an opening/closing valve. The vehicle air-conditioning device includes a refrigerant circuit R having a compressor 2, a radiator 4 to perform heat exchange between a refrigerant and air, an outdoor heat exchanger 7, a heat absorber 9, and a solenoid valve 40. The compressor 2 and the solenoid valve 40 are controlled to air-condition a vehicle interior. A decompression speed at a refrigerant inflow side of the solenoid valve when the compressor 2 is stopped and the solenoid valve 40 is closed is faster than that at a refrigerant outflow side thereof. When operation is stopped from a state in which the compressor 2 is operating with the solenoid valve 40 being in an opened state, the opened state of the solenoid valve 40 is maintained even after the compressor 2 is stopped.
