摘要： A vapor compression system control implementations that maintain surface temperature uniformity of at least one cold plate throughout pulsed thermal loads from a minimal or zero load state suddenly to a high or 100% of design capacity state where the heat pulse occurrence, frequency, and durations are not known a priori. Vapor compression system control implementations that maintain surface temperature uniformity of at least one cold plate throughout pulsed thermal loads from a minimal or zero load state suddenly to a high or 100% of design capacity state where the heat pulse occurrence, frequency, and durations are not known a priori. Rapid thermal pulse applications require a robust control strategy of the cold plate assembly to maintain cold plate surface temperature uniformity. In one implementation, a control system for the cold plate assembly that maintains a uniform cold plate temperature given controlled supply and suction conditions is contemplated.

摘要： A bypass line is described that is capable of equalizing pressure within an HVAC system. The bypass line can also cause less noise than other solutions. A bypass line under the present disclosure can comprise a line from a high pressure side to a low pressure side of an HVAC system. Valves and orifices can be disposed within the bypass line. The valves and orifices help to slow the speed of fluid from high pressure to low pressure locations, thus reducing noise during pressure equalization.

摘要： A heat pump vehicle air conditioning system passes hot gas to a condenser and a vaporizer for the vehicle cabin exterior. Even with low outside air temperature, it can efficiently defrost using the cooling cycle. The system includes a cabin-interior condenser downstream of a cabin-interior vaporizer within an HVAC unit connected via refrigerant switching means to a cooling cycle. Cooling is accomplished by a compressor, cabin-exterior condenser, first decompression unit with on-off valve function, the cabin-interior vaporizer, and an accumulator. A cabin-exterior vaporizer disposed outside of the vehicle cabin is connected with a second decompression unit via an on-off valve function and to the exit-side liquid refrigerant pipe of the cabin-exterior condenser. A bypass circuit having a third decompression unit with on-off function is connected between the accumulator and the exit-side liquid refrigerant pipe of the cabin-exterior condenser.

摘要： There is disclosed a vehicle air conditioner capable of preventing or inhibiting deterioration of a vehicle interior heating capability which is caused by frost formation to an outdoor heat exchanger. The vehicle air conditioner includes a compressor 2, an air flow passage 3, a radiator 4, a heat absorber 9, and an outdoor heat exchanger 7, and executes a heating mode in which a refrigerant discharged from the compressor radiates heat in the radiator, is decompressed and then absorbs heat in the outdoor heat exchanger. The vehicle air conditioner includes an accumulator 12 disposed on a suction side of the compressor, and a bypass circuit 24B disposed from a refrigerant outlet side of the radiator to an inlet side of the accumulator. A controller has a mode in which the refrigerant flowing out from the radiator is passed through the bypass circuit, does not flow through the outdoor heat exchanger, but flows into the accumulator.
