초록

R-134a 대체 냉매인 HFO-1234yf의 성능을 가정용 냉동/냉장고에서 평가하였다. AHAM(Associ- ation of Home Appliance Manufacturers) 규격에 의거하여 HFO-1234yf를 Drop-in하여 냉매 봉입량 시험, Pulldown 시험, 냉각속도 시험 그리고 소비전력 시험을 수행하였으며, R-134a 실험 결과와 비교하였다. $43^{\circ}C$ 고온 가혹 조건에 서도 시험을 수행하였다. 결과적으로 HFO-1234yf 냉매는 Cycle 성능면에서는 R-134a와 유사하나, 냉각속도는 모세관경을 더 크게 변경시켜야 한다.

The performance of HFO-1234yf as a substitute for R-134a was evaluated in a household freezer/refrigerator. A series of tests such as 'refrigerant charging test, pull-down test, cooling speed test, and energy consumption test were carried out under the AHAM (Association of Home Appliance Manufacturers) standard. The results of a drop-in test were compared with those of a test conducted using R-134a. A test under a severe ambient air condition ($43^{\circ}C$) was also conducted. The result shows that the refrigeration cycle performance of HFO-1234yf is as good as that of R-134a ; however, the diameter of capillary tube should be increased in order to improve its performance in the cooling speed test.
