application: retrofitedrefrigerant for r22
1. it provide a direct replacementthat is simple, efficient and economical. a simpler replacementthan r22. 
2. it is a kind of hfc refrigerant,and its odp value is zero. 
3. it is compatible with bothtraditional and new lubricants. in most cases, it doesn't need tochange the lubricant during replacement process. 
4. all the spot tests are successfulup to now, and it doesn't need to change the expansion valve oftemperature regulation. may need to adjust the degree ofsuperheat. 
5. existing equipment can still beused. 
6. its gwp value is 50% lower thanr22.
