Abstract

Refrigeration is the process of removing heat from a confined space in order to lower the temperature below that of the surrounding environment. Refrigeration is the process of cooling a surface or volume by boiling and condensing a refrigerant. In order to prevent the accumulation of the ice that could layered-up around the cooling coil defrosting mechanism is employed in refrigerators. We used four different defrosting procedures and compared them based on the amount of time it took to defrost. Among the procedures given, defrosting the ice using a dryer is the best and fastest.
