Alternative Defrost Strategies for Residential Heat Pumps [PDF]

, 2018
Heat pumps are an energy efficient way to provide adequate heating to an indoor space. In contrast to electric or gas heating, a heat pump works to draw the free heat from the cold outdoor ambient and transfer thermal energy to the heated space.

An Experimental Investigation of Defrost Heaters Applied To Domestic Refrigerators

, 2019
The frost accumulated over evaporator surface upsurges the thermal resistance between air in evaporator chamber and evaporator surface, also the air side pressure drop increases and reduces the performance of the refrigerator.
