摘要
研制了创新型制冷循环综合实验仪,使用了R134a绿色环保型制冷剂,改进了制冷循环系统,采用延时继电器设计了电流表和功率因数表的保护电路。
A new refrigeration cycle integrative instrument was developed. Using non-polluting cold-producing medium R134a and devising the protective circuit of ammeter and power factor meter with time delay relay, it improved the properties of the refrigeration cycle instrument.
