摘要(Abstract):

介绍了当前制冷装置和热泵系统中常用的除霜方法和除霜控制的研究现状,着重讨论了用一个温度点预测结霜量方法和最佳除霜点控制方法。其中的技术参数可为制冷和热泵系统的设计人员提供参考。
Some defrosting methods in refrigerating plant and heat pump system and some researches about defrosting control were introduced.The method of forecasting the amount of frost with one temperature and the methods of getting the optimal defrosting point were emphasized.Some technical parameters can be used in refrigeration and heat pump system design.

关键词(KeyWords): 除霜;除霜控制;最佳除霜点
