HVAC SYSTEM FOR A VEHICLE AND METHOD OF USE

The present disclosure provides an HVAC system for a vehicle having a first heat source and comprising a primary loop through which a coolant circulates and a secondary loop through which refrigerantcirculates. The primary loop having two parallel sub-loops, namely a first sub-loop and a second sub-loop in which the coolant may circulate. The first sub-loop of the primary loop includes the firstheat source, a second heat source, and a first heat exchanger. The first sub-loop may partially extend into a case of the HVAC system to place the first heat exchanger adjacent an air heater. The second sub-loop of the primary loop includes the first heat source, the second heat source, and a second heat exchanger. The HVAC system having a plurality of operation modes for efficiently conditioningair in a cabin of the vehicle. 本申请涉及用于车辆的HVAC系统及使用方法。本发明提供了种用于车辆的HVAC系统，其具有第热源并且包括冷却剂循环通过的主回路和制冷剂循环通过的次级回路。主回路具有两个并联的子回路，即冷却剂可在其中循环的第子回路和第二子回路。主回路的第子回路包括第热源、第二热源和第热交换器。第子回路可部分地延伸到HVAC系统的壳体中以将第热交换器放置在空气加热器附近。主回路的第二子回路包括第热源、第二热源和
