Control of mechanism of crystallization and inhibition ofcrystal growth of frost-crystal

霜冻的形成往往会导致冰箱和热泵等消费品的性能恶化。通常，除霜是通过定期融化设备热交换器上的霜层来进行的。在这里，我们提出了一种新的机械方法，使换热器在除霜的同时仍能保持低温。为了评估结霜过程，我们在实验研究中使用了一个新的参数，即从冷却表面刮掉霜层所需的力。我们成功地控制了结晶机理，抑制了霜晶的生长。

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.
