Abstract

This paper studies the importance of temperature control in household refrigerator on the economic and environmental plan. Refrigerator energy consumption is greatly affected by room temperature, door opening and thermostat regulation. A household refrigerator powered by photovoltaic energy was tested in laboratory to determine the effect of thermal regulation on energy consumption. Our investigation reveals that there is a difference in minimal average temperature between the thermostat and the evaporator for three different thermostat positions. This difference in temperature was justified by three parameters : the bad contact between the thermostat bulb and the surface of the evaporator, thermostat thermal inertia and the error due to the mechanical control of the thermostat. Finally, we represent the annual economic deficit caused by the thermal regulation on the number of families around the world.
