Abstract
Exterior variable displacement compressor (EVDC) has been more and more widely used for modern vehicles. Comparing with interior variable displacement compressor, EVDC can solve the problems of bad control precision, slow feedback timing, unremarkable energy saving effect, system surge and evaporator freeze. This article presents the advantage and working theory of EVDC, emphases on the internal structure of EVDC, control theory, vehicle calibration and control for EVDC.关键词
