摘要
详细分析了过冷制冷循环特性和空调常用的四种制冷剂(R22、R134a、R407C、R410A)的过冷度对制冷循环制冷量、耗功和性能系数COP的影响,并拟合了过冷度对循环性能参数影响的关系式。针对冰蓄冷系统给出了过冷度控制数值和冷量提高的程度。
This paper has analyzed the characters of sub-cooled refrigeration cycle and introduced the influence on refrigerating effect, power consumption and coefficient of performance （COP） by sub-cooling degree of some refrigerants （R22. R134a. R407C. R410A）. It also presents the relational expression between sub-cooling degree and performance parameters. For ice storage system, the paper gives some advices to choose sub-cooling degree and increase refrigerating effect.
