[Abstract]:In theory, the use of regenerative tubes in R134a automobile air conditioning system can significantly improve the refrigeration performance. However, some experimental studies show that the use of regenerative pipes has a negative impact on the system and offsets the benefits. The improvement of refrigeration performance is not obvious and there are some safety risks. In this paper, a comparative experimental study on different length regenerative tubes is carried out by using a comprehensive performance test bench of air conditioning system, and the relationship between the adverse effect of the system and the length of the tube is obtained. In addition, through the expansion valve regulation experiment, the condensing air volume control experiment and the oil quantity control experiment, the method to avoid the adverse effect is obtained, which provides a certain theoretical basis for the matching adjustment of the regenerative system.
