초록

This study was performed to design the optimal block type expansion valve through analyzing the characteristics of the block type expansion valve in automotive air conditioning system using HFC-134a. Because an alternative refrigerant (HFC-l34a) is being used instead of CFC-12 for automotive air conditioning system, newly designed air conditioning components are necessary due to changes in characteristics. The performance tests were accomplished through the test bench, that is manufactured based on the study. And then it was carried out to measure the variation of temperature and pressure at each part of the air conditioning system according to the compressor speed.
