This paper deals with che test and measurement of the performances of heat transfer and fluid resistance in the rear cooler of a air compressor by using transversally corrugated, spirally grooved and plain enhanced pipes as heat-transfering elements and compressed air and water as heat-exchanging media .

In view of the generally existing problems of the leakage,unstability and the large loss of fluid resistance about the check gate of taper valve,this article analyses theoretically the cause of such leakage and puts forward some tentative ideas of improvement.

With pipe/tube fluid resistance considered, a MAU fluid network model was built by a series of fluid circuits of different refrigerating components including single-phase pipes and two-phase electronic expansive valve(EEV), evaporator, pipes in parallel or series.
