Firstly a conventional development process of anti-frosting in automotive AC system with fixed capacity air compressor is described in this article. With the development process of anti-frosting in a modified automotive AC system as example, and with test measurement method and CFD virtual analysis method, the root of the problems during the development course is reproduced intuitively. Then the factors, i.e. EAT sensor type and position as well as set value, AC unit structural difference, monomeric test rig, system test rig and vehicle test, etc, which affect the development of anti-frosting performance of AC system with fixed capacity compressor are analyzed in the paper.
