The performance of HFO-1234yf as a substitute for R-134a was evaluated in a household freezer/refrigerator. A series of 'Refrigerant charging test', 'Pulldown test', 'Cooling speed test' and 'energy consumption test' were carried out under AHAM(Association of Home Appliance Manufacturers) standard. The results of drop-in test were compared with those of R-134a. Test was also conducted at severe ambient air condition (43℃). The result shows that HFO1234yf is as good as R-134a in a cycle performance but the diameter of capillary tube should be changed to larger one for cooling speed.
