Problems solved by technology
In addition, in the heating mode, the HVAC air volume is relatively small, so the heating capacity is also limited
If the size of the indoor heat exchanger is to be increased, it is necessary to re-design the HVAC and re-invest in the mold, which increases both development time and production costs
On the other hand, the current heat pump air-conditioning system with three heat exchangers cannot meet the ambient temperature for defrosting in the standard GB / T 24552-2009 "Performance Requirements and Test Methods for Windshield Defrosting and Defogging Systems of Electric Vehicles" Should be specified as -18℃±3℃

Description
technical field [0001] The invention belongs to the technical field of a heat pump air conditioner for a new energy vehicle and a battery pack thermal management, in particular to an integrated passenger compartment air conditioner for a new energy vehicle and a heat pump system for thermal management of a battery pack. Background technique [0002] Due to factors such as shortage of oil resources and environmental protection, governments and automobile manufacturers around the world are vigorously promoting new energy vehicles. For the development of new energy vehicles, the power battery is the top priority of the three-electric system of new energy vehicles. At present, ternary lithium batteries are recognized as power batteries suitable for new energy vehicles due to their high energy density. However, ternary lithium batteries are particularly sensitive to temperature. Therefore, the thermal management of new energy vehicles is highly valued by everyone. In addition, ...
