冷库制冷系统液体冷媒除霜结束时的回气管温度研究

摘要

Hot liquid refrigerant defrosting is a new defrosting method. In this paper, the method of hot liquid refrigerant defrosting was firstly introduced. And then .taking the evaporator muffler temperature as the control parameter that indicated the ending of defrosting, the experimental device and method were described and the experimental data was analyzed. The experimental results demonstrated that taking the muffler temperature as the control parameter that indicated the ending of defrosting in cold storage refrigeration system was feasible. Furthermore, when the temperature in cold storage refrigeration system was higher, the muffler temperature at the end of the defrosting would be lower,and vice versa.%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.
