Thermal power regulating process of an air stream directed inside an air conditioned vehicle passenger compartment

摘要

External air (AE) enters a centrifugal pump (26) and flows through a first heat exchanger (ECH1) liked to a refrigerating liquid and compressor (28). A flap valve (30) deflects some air through a second exchanger (ECH2) with cooling water and the mixture (Fsou) passes to the cabin. A calculator (ECU) eliminates the need for cabin and first heat exchanger temperature sensors (Csou,C1) by detecting compressor operation and using stored tables
