  • Patent number: 10996007
    Abstract: A vehicle air-conditioning apparatus includes a refrigerant circuit including a heat exchanger, a fan which sends air to the heat exchanger, and a controller which controls the refrigerant circuit and the fan. The vehicle air-conditioning apparatus is mounted on a vehicle. The controller determines if a position of the vehicle or a speed of the vehicle satisfies a predetermined condition. The controller acquires a physical quantity, the physical quantity having already been correlated with a clogging amount of the heat exchanger and the correlation being dependent on whether the predetermined condition is satisfied. The controller determines whether or not clogging occurs in the heat exchanger based on the physical quantity.

  • Patent number: 10882001
    Abstract: A process for removing a foulant from a gas stream. The gas stream is cooled in a series of heat exchangers, causing a portion of the foulant to desublimate and become entrained in a cryogenic liquid. This foulant slurry stream is pressurized, cooled, and separated into a pressurized foulant solid stream and the cryogenic liquid stream. The pressurized foulant solid stream is melted to produce a liquid foulant stream. Heat exchange processes, both internal and external, are provided that close the heat balance of the process. In this manner, the foulant is removed from the gas stream.

  • Patent number: 10843527
    Abstract: A vehicle air conditioner has a bypass pipe which passes a radiator, an outdoor expansion valve, and opening/closing valves. A controller is configured to execute a heating mode to open a first solenoid valve and close a second solenoid valve, and a dehumidifying and heating mode to close the first solenoid valve, open the second solenoid valve, let a refrigerant radiate heat in an outdoor heat exchanger, let the refrigerant absorb heat in a heat absorber, and generate heat in an auxiliary heater. When changing from the heating mode to the dehumidifying and heating mode, the controller sends the refrigerant to a receiver drier, controls a compressor to reduce a difference between pressures before and after the second solenoid valve, opens the second solenoid valve, closes the first solenoid valve, shuts off the outdoor expansion valve, and shifts the compressor to control in the dehumidifying and heating mode.
