液体冷媒除霜是一种新型的除霜方式。本文首先介绍了液体冷媒除霜的方法,而后对以蒸发器回气管温度作为除霜结束控制参数的实验装置、实验方法和实验数据进行了分析。实验研究结果表明,把回气管温度作为液体冷媒除霜系统除霜结束时的控制参数是可行的,库温高的制冷系统除霜结束时的回气管温度较低,库温低的制冷系统除霜结束时的回气管温度则较高。 Liquid refrigerant defrosting is a new type of defrosting method. This paper firstly introduces the method of liquid refrigerant defrosting, and then analyzes the experimental device, experimental methods and experimental data with the return air temperature of the evaporator as the defrosting end control parameter. Experimental results show that it is feasible to use the return air temperature as the control parameter at the end of defrosting of the liquid refrigerant defrosting system. The temperature of the return air pipe at the end of defrosting of the refrigeration system with high reservoir temperature is low, and the refrigeration system with low reservoir temperature Return air temperature at the end of the frost is higher.
