The aim of this paper is to study comparative analysis of household direct cool vertical evaporator refrigerator with 134a and R1600a refrigerant. In this household refrigerator, usable cabinet space is improved by 25~30 % with roll bond vertical evaporator by instead of conventional c or o type roll bond evaporator. This improvement in usable space is based on volume of existing evaporator ie freezer section of house hold direct cool refrigerator .Based on 43°C pull down test , freezer section becomes warmer by approximately 9°C~-12°C so it can be considered as refrigerator without freezer compartment. Further extension to above experiment R134a compressor and refrigerant is replaced by R600a compressor and refrigerant. Based on 32°C energy consumption test, vertical evaporator refrigerator with R600a refrigerant consumes 7~8 % less energy than vertical evaporator refrigerator with R134a refrigerant.
