摘要： A vehicle-mounted cooling system includes an air-conditioning refrigerant circuit including a refrigerant passage, a compressor, a heat source-side heat exchanger and a use-side heat exchanger, a battery, and a battery cooling unit cooling the battery using the refrigerant. A control device controls a drive state of the compressor in response to an air-conditioning request and a battery cooling request. The control device includes an abnormality determination unit configured to determine whether an abnormality has occurred in the air-conditioning refrigerant circuit, and a control mode change unit configured to perform, under a situation where the battery cooling request has occurred and it is determined that an abnormality has occurred in the air-conditioning refrigerant circuit, a change of a refrigerant-circulation control mode while permitting the battery cooling unit to continuously cool the battery based on the refrigerant, the refrigerant-circulation control mode representing how the refrigerant is circulated in the air-conditioning refrigerant circuit.

摘要： An exemplary vehicle is disclosed having a compressible fluid system including at least one sensor configured to determine a fluid pressure present within the compressible fluid system, and a circulator configured to circulate air in the engine compartment. The vehicle is configured to activate the circulator in response to a decrease in the fluid pressure, and in some approaches may also open a grill shutter or other fluid passage into the engine compartment. Exemplary methods may include providing a circulator configured to selectively circulate airflow, e.g., into an engine compartment of a vehicle, and detecting a fluid pressure decrease within a compressible fluid system in the engine compartment. The circulator may be activated to circulate air in the engine compartment in response to at least the detected fluid pressure decrease.

摘要： An integrated cooling system having two separate evaporator coils is provided. Each evaporator coil has its own shutoff, thereby allowing for individual control over the cooling of each of two vehicle spaces. The evaporator coils may be disposed within the vehicle to cool the passenger compartment and a battery compartment, respectively. The separate control afforded by the cooling system provides the flexibility of shutting off cooling to the vehicle passenger compartment for the comfort of the vehicle occupants, while still providing cooling to the battery, as needed. The cooling system includes a number of control features which provide for automatically shutting off cooling to one or more of the evaporator coils based on parameters such as air temperature and refrigerant pressure.

摘要： When a heating mode is set in a refrigerant cycle system, air is heated in a condenser by condensing high-pressure gas refrigerant, a part of high-pressure refrigerant from the condenser is decompressed in a pressure reducing unit to a middle pressure, and the other part of high-pressure refrigerant from the condenser is heat-exchanged with the middle-pressure refrigerant having passed through the pressure reducing unit in a refrigerant-refrigerant heat exchanger. Therefore, middle-pressure refrigerant having passed through the pressure reducing unit is evaporated in the refrigerant-refrigerant heat exchanger and the evaporated middle-pressure refrigerant is introduced into a gas injection port of a compressor. Thus, in the refrigerant cycle system, heating capacity can be improved due to the gas refrigerant injection into the compressor.
