Abstract: The present invention provides a vehicle air conditioning system and a vehicle air conditioning method that increase heating performance while recovering exhaust heat from onboard equipment. The vehicle air conditioning system comprises: a refrigerant circuit; a heat medium circuit including a high-temperature medium circuit and a low-temperature medium circuit; an interior heat exchanger that exchanges heat between a heat medium and air; an exterior heat exchanger that exchanges heat between the heat medium and outside air; an exhaust heat recovery circuit; and a switching part. The following are provided as operating modes; an exhaust heat-recovery heating mode in which the heat medium in the high-temperature medium circuit is supplied to the interior heat exchanger and exhaust heat from onboard equipment is recovered by the heat medium in the low-temperature medium circuit, while the heat medium that has recovered and transferred exhaust heat to the refrigerant is supplied to the exterior heat exchanger; and an exhaust-heat-as-main-heat-source heating mode in which the heat medium in the high-temperature medium circuit is supplied to the interior heat exchanger and exhaust heat from onboard equipment is recovered by the heat medium in the low-temperature medium circuit, while the heat medium that has recovered and transferred exhaust heat to the refrigerant is caused to bypasses the exterior heat exchanger.

Abstract: A vehicle air conditioner includes a refrigeration cycle unit, a heater core, a cool air bypass passage, an air volume ratio regulator, and an auxiliary heat exchanger. The heater core is disposed in a heating passage located downstream of an evaporator with respect to an airflow. The auxiliary heat exchanger is provided in the refrigeration cycle unit. The evaporator includes a cold energy storage configured to store cold energy. The cold energy storage stores cold energy when the compressor is in operation, and dissipate cold energy while the compressor stops. The auxiliary heat exchanger is located downstream of the evaporator and upstream of the heater core with respect to the airflow. The auxiliary heat exchanger is configured to change enthalpy of refrigerant by heat exchange between the refrigerant and air having been cooled by the evaporator and to be heated by the heater core.

Abstract: The present disclosure relates to a temperature control system of an electric vehicle. A circulation flow path includes 1st-4th and a high-temperature flow paths. A liquid temperature adjustment device is disposed on the first flow path. A compartment heat exchanger is communicated with the liquid temperature adjustment device through the first flow path, and communicated with a heat-dissipation device through the second flow path. A motor cooling circuit is communicated with the heat-dissipation device. A flow path switch is connected with a first inlet, a second outlet and a fourth outlet through the first flow path, the third flow path and the fourth flow path. The high-temperature flow path is bridged between the second flow path and the fourth flow path. The first flow path is selectively communicated with the third flow path or the fourth flow path by the flow path switch. Therefore, the issues and inconvenience are solved.

Abstract: A battery thermal management system includes a passenger cabin air-conditioning refrigerant loop including at least one evaporator in fluid communication with a chiller and a battery pack coolant loop in fluid communication with the chiller. A controller is configured to determine whether a temperature of the at least one evaporator falls within a predetermined temperature range, and if so to cause a valve to bypass a refrigerant from the air-conditioning refrigerant loop to the chiller. Evaporator temperature is determined by providing at least one evaporator temperature sensor.
