阐述了PROA添加剂 (polarizedrefrigerantoiladditive)的润滑和增强盘管传热的原理 ,对PROA添加剂在工程中的应用进行了测试 ,测试结果表明制冷机 (活塞式 )的COP值明显提高 ,而且制冷机使用年限越长 ,加入PROA后制冷机 (活塞式 )的COP值增加越明显
The principle of lubrication and enhanced coil heat transfer of PROA additive was elaborated. The application of PROA additive in engineering was tested. The test results show that the COP value of the refrigerator (piston) is significantly increased, and the service life of the refrigerator The longer the COP value of the refrigerator (piston type) increases after the PROA is added
