摘要： A vehicle thermal management system including an electric powertrain, a single thermal loop, and a controller is provided. The electric powertrain includes a high voltage battery. The single thermal loop is for managing thermal conditions of the high voltage battery and a vehicle cabin and may include a climate control system, a blower, and a front evaporator in fluid communication with the vehicle cabin. The controller is programmed to, responsive to detection of a climate control system off request, output a command to direct the blower to push air through a heater core to the vehicle cabin at a predetermined temperature such that a temperature within the vehicle cabin is maintained at a predetermined temperature and refrigerant continues to flow through the front evaporator. The system may include a vehicle cabin temperature sensor and an ambient temperature sensor, each in electrical communication with the controller.

摘要： An air conditioning system for use in a vehicle includes at least one compressor, a condenser disposed downstream of the at least one compressor and a plurality of evaporators disposed downstream of the condenser with first and second evaporators fluidly coupled to each other in parallel. The at least one compressor, the condenser, and the plurality of evaporators are fluidly connected by refrigerant lines to form a refrigerant circuit. The air conditioning system also includes a plurality of shut-off valves, with one shut-off valve installed at a refrigerant inlet and another shut-off valve installed at a refrigerant outlet of the first evaporator. The shut-off valves are controlled to prevent undesired collection of refrigerant in the first evaporator.

摘要： There is disclosed a vehicle air conditioning device of a heat pump system which delays proceeding of frosting onto an outdoor heat exchanger, thereby eliminating or inhibiting deterioration of a heating capability due to the frosting. The vehicle air conditioning device executes a heating mode in which a controller lets a refrigerant discharged from a compressor 2 radiate heat in a radiator 4, decompresses the refrigerant by which heat has been radiated, and then lets the refrigerant absorb heat in an outdoor heat exchanger 7, and on the basis of a difference TXO=(TXObase−TXO) between a refrigerant evaporation temperature TXObase of the outdoor heat exchanger 7 in non-frosting and a refrigerant evaporation temperature TXO of the outdoor heat exchanger 7, the controller corrects a target subcool degree TGSC that is a target value of a subcool degree of the refrigerant in the radiator 4 in an increasing direction in accordance with increase of the difference ΔTXO.

摘要： An air-conditioning system with a refrigerant circulation circuit, which has improved control precision for maintaining a compartment temperature and improved response characteristics. The refrigerant circulation circuit includes a variable displacement type compressor, the discharge capacity of which is controlled by a control valve. The control valve detects a differential pressure between two pressure monitoring points in the refrigerant circulation circuit as an index for estimating the refrigerant discharge capacity of the variable displacement type compressor and performs feedback control of the discharge capacity of the compressor such that the differential pressure converges to a set differential pressure. A controller determines or recomputes the set differential pressure based on information from a mode switching unit or an air-flow-rate switch and instructs the control valve to change the set differential pressure accordingly. The switch information from the mode switching unit or the air-flow-rate switch signals the controller of a sudden change in the cooling load before the occurrence of the change or at the same time as the change occurs.

摘要： In a refrigerating cycle with a by-pass line 5 detouring the condenser 2 in an auxiliary heating mode the amount of circulated refrigerant is controlled in accordance with load, etc. so that the heating can be suited to such conditions. A regulator 20 for controlling the outlet pressure of the evaporator to a fixed level allows to use an evaporator 4 having ordinary pressure resistance. An accumulator 6 for temporarily storing low-pressure refrigerant liquid is provided between the outlet of evaporator 4 and a compressor 1. In an auxiliary heating mode the amount of the circulated refrigerant passing the by-pass line 5 is controlled by the accumulator 6. Simultaneously the regulator is controlling the outlet pressure of the evaporator to an essentially fixed level.

摘要： The valve opens in response to a predetermined small pressure differential acting across the valve. As the pressure differential increases, the valve throttles the flow and when a high pressure differential exists the valve closes. The valve is designed to be placed in a by-pass circuit in an automotive air conditioning system to provide adequate flow under low cooling loads to cool and lubricate the compressor. Under normal and high evaporator loads, the by-pass flow is throttled or closed off completely to avoid needless consumption of energy.

摘要： A climate control circuit for a transport climate control system is provided. The circuit includes a compressor, a plurality of evaporators, a suction flow control device, and a controller. The suction flow control device is downstream of the plurality of evaporators and directs the working fluid from each of the evaporators to one of a main suction port and an auxiliary port of the compressor. The controller determines whether each of the evaporators is operating in a fresh temperature range or in a frozen temperature range. For each of the evaporators operating in the fresh temperature range, the controller instructs the suction flow control device to direct the working fluid from the corresponding evaporator to the auxiliary suction port. For each of the plurality of evaporators operating in the frozen temperature range, the controller instructs the suction flow control device to direct the working fluid to the main suction port.
