This study presents the effects of different operating variables on energy consumption of refrigerator-freezer that had two phases. The first phase is to investigate the effects of the number of door opening, duration of each door remain open, ambient temperature, cabinet load and thermostat setting position on energy consumption during the open door conditions. The second phase is to investigate the effects of the ambient temperature, cabinet load, thermostat setting position and open surface water pan area inside the cabinet on energy consumption during the closed door conditions. All the experiments were conducted in the environmental controlled chamber. The result shows that there is a great influence of different variables on energy consumption and average consumption is about 3.3 kWh day-1. The effects of number of door opening, ambient temperature and cabinet load are more compared to the others. The open door energy consumption is 40 more compared to the closed door test. It is found that the average of the maximum energy consumption is 27.3 more compared to average consumption and 55.6 more compared to average of the minimum consumption. If the users be serious, a significant amount of energy could be saved with the proper utilization of refrigerator-freezer.
