摘要： A cooling system has a primary stage; and a secondary stage including a secondary pressure reducing device configured to adopt a passive state and an active state, a cooling section for cooling an electric storage device, a pump, a secondary compressor, and a valve device arranged to selectively direct the refrigerant to the pump or to the secondary compressor. The secondary stage is controlled to operate in a first mode where the secondary pressure reducing device adopts the passive state, and the valve device directs the refrigerant to the pump; and control the secondary stage to operate in a second mode where the secondary pressure reducing device adopts the active state, and the valve device directs the refrigerant to the secondary compressor. In the second mode, the refrigerant is conveyed by the secondary stage is condensed in cooperation with the primary stage.

摘要： A method of minimizing C-Rate fluctuations with an electrically powered accessory (EPA) is disclosed. The EPA is configured to be used with at least one of a vehicle, a trailer, and a transport container that has a first controller. The EPA has a second controller. The method includes determining, by the first controller, a first C-Rate of a Rechargeable Energy Storage System (RESS). Also, the method includes comparing the first C-Rate to a first predetermined threshold. The method also includes when the first C-Rate exceeds the first predetermined threshold, the first controller sending a first request to the second controller to adjust a load of the EPA. The method further includes the second controller determining a first operational mode of the EPA based on the first request. Also the method includes when the first operational mode of the EPA allows a load change, the second controller adjusting the load of the EPA.

摘要： A method for controlling heating of a vehicle thermal management system including an HVAC subsystem may include: determining, by a controller, a target temperature for heating a passenger compartment of a vehicle when the HVAC subsystem operates in heating mode; determining, by the controller, whether an internal temperature of the passenger compartment is lower than the target temperature; adjusting, by the controller, an opening amount of a heating-side expansion valve of the HVAC subsystem to a first opening amount and opening the heating-side expansion valve when the internal temperature is lower than the desired target temperature; and decreasing, by the controller, RPM of a compressor of the HVAC subsystem when the internal temperature is higher than or equal to the desired target temperature. The first opening amount is an opening amount of the heating-side expansion valve with which a heat capacity generated by a heating operation of the HVAC subsystem reaches a maximum heat capacity.

摘要： A temperature control system includes a heater core utilizing heat of a heat medium; an engine heat exchanger utilizing exhaust heat of an engine to heat the heat medium; a condenser utilizing heat other than the exhaust heat to heat the heat medium; a heat circuit having the heater core and condenser; a communication flow path making the engine heat exchanger communicate with the heat circuit; and a connection state switching mechanism switching a flow state of the heat medium, between a first state and a second state. In the first state, the heat medium flows through the heat circuit, while flowing through the heater core, and in the second state, the heat medium flows through the heat circuit without flowing through the heater core. The heat circuit is arranged at a front of a passenger compartment, and the engine heat exchanger is arranged at a rear of the compartment.

摘要： This electric compressor control device comprises: a control unit of an inverter which controls a motor that drives a compressor; a physical quantity calculation unit which calculates, on the basis of one or a plurality of predetermined detection values acquired from the inverter, a physical quantity that varies depending on a workload of the compressor; a number-of-revolutions acquisition unit which acquires the number of revolutions of the motor; a storage unit which stores information representing a first threshold that varies depending on the number of revolutions of the motor, and defines whether or not the physical quantity is a normal value; and a refrigerant abnormality determination unit which determines whether or not there is an abnormality in a refrigerant system by comparing the calculated physical quantity with the first threshold, depending on the acquired number of revolutions.

摘要： Thermal management in a vehicle involves a compressor to output a refrigerant in vapor form for circulation in a refrigerant loop. A thermal management system includes a heating, ventilation, and air conditioning system in the refrigerant loop including an evaporator and an HVAC condenser, and an exterior condenser in the refrigerant loop configured to vent heat to an exterior of the vehicle. A first variable refrigerant flow valve controls a flow rate of the refrigerant output by the compressor into the HVAC condenser, and a second refrigerant flow valve controls a flow rate of the refrigerant output by the compressor into the exterior condenser. A controller controls the first refrigerant flow valve and the second refrigerant flow valve based on a target output temperature for the HVAC condenser.
