  • Patent number: 10926604
    Abstract: An air conditioner for performing air-conditioning of an interior of a vehicle cabin includes a casing, an evaporator, a blower, a controller, and a cooling passage. The casing defines a ventilation passage through which air flows from an air introduction port toward an air outlet. The evaporator cools the air flowing through the ventilation passage. The blower is disposed on a downstream side with respect to the evaporator in the ventilation passage and generates an airflow in the ventilation passage. The controller controls an output from the blower. The cooling passage causes a position located on a downstream side with respect to the blower in the ventilation passage to communicate with a position located on an upstream side with respect to the evaporator in the ventilation passage. A controller is installed in the cooling passage.

  • Patent number: 10926609
    Abstract: There is disclosed a vehicle air conditioning device which is capable of judging, as early as possible, refrigerant shortage, for example, due to leakage of refrigerant with elapse of time, and protecting a compressor. The vehicle air conditioning device includes a compressor 2, a radiator 4, an outdoor expansion valve 6, and a heat absorber 9. A control device possesses normal time data indicating a relation between a suction refrigerant temperature Ts and a discharge refrigerant temperature Td of the compressor when a refrigerant circuit R is charged with a sufficient amount of the refrigerant. The control device calculates, from the normal time data, a discharge refrigerant temperature estimated value Tdst at normal time on the basis of the current suction refrigerant temperature Ts, and compares the value and the current discharge refrigerant temperature Td, thereby judging refrigerant shortage of the refrigerant circuit.

  • Patent number: 10894608
    Abstract: A thermal management system for a pulse load on an aircraft. The thermal management system utilizing the reserve fuel from the aircraft to create thermal capacitance such that the instantaneous capacity of the cooling system to remove heat from the aircraft may be sized less than the rate of heat generated by the pulsed load (e.g. laser, radar, rail gun etc.) The reserve fuel is maintained at a temperature in a reservoir and cooled via a cooling system. Fuel from the reservoir is selectively mixed with fuel exiting the pulsed load heat exchanger to provide fuel to the inlet of the heat exchanger at a predetermined temperature, the temperature based at least upon the heat generated by the laser, flow rate of fuel and efficiency of the heat exchanger.
