This study is to design and verify the Climate Control System for this BN car, the key work is to solve the 3 disadvantages of their current product, KY car.It starts the work from the bench marking for KY and I7 car, and then define the system level target, casecade the design work from system level to function components level. And with the system bench help, the system integration work is done, and the high discharge temperature issue is deeply studied with some backup solutions. Meanwhile, it is compared with QCT method of system bench performance test. Finally, the Climate Wind Tunnel test shows very good performance result, the system performance and target is verified.During this study work, it is almost a classic vehicle original design procedure. And some key issues are deeply studied and solved. It is really a suml/ressful Climate Control System developing case.
