| Research Abstract |
Frost formation can often lead to a deterioration of the performance of consumer products such as refrigerators and heat pumps. Generally, defrosting is carried out by melting the frost on the heat exchangers of the devices periodically. Here, we propose a new mechanical method in which the heat exchangers can still maintain their low temperatures while defrosting. To evaluate the frosting process, we used in this experimental investigation a new parameter, which is the force required scrap off the frost from the cooling surface. We have succeeded at controlling the mechanism of crystallization and inhibiting the crystal growth of frost-crystal.
