摘要

Heating-air conditioning system comprises a high performance heat exchanger (4m) with a soldered heat exchange matrix consisting of flat tubes on the coolant side and ribs on the air side with a number of louvers producing a turbulence in the air flow direction. Preferred Features: The average distance between the heat exchange ribs on the air side is less than 1.0 mm and the average distance between the flow channels is less than 7 mm.
