This paper carried out a comparative analysis with papers on the analysis and analytic research ofconventional solenoid. In case the current of solenoid valve is cut off, a flow path is formed from pressureport (Pc) connected with the crankcase of compressor to Ps port. At this time, the size of Pc port hole wasso adjusted (Type-2) that it was smaller than 4.0mm(Type-1) of original hole by 0.2mm. After that, it wasthought that an effect would be produced on the flow change of refrigerant which came into the solenoidvale, therefore the flow characteristics in moving from Pc port to Ps port was predicted and comparativelyanalyzed. According to the results of flow analysis, a velocity of approximately 46m/s and 129m/s was shownat the maximum in case of 0.2 and 1.5 MPa in Type-1, and the maximum velocity of approximately 500m/sand 1400m/s was shown in case of Type-2.
