1)、 it is the last replacement of R-22 and R-502 and good in all the environmental protection characters.
2)、It is non-toxicity, non-inflammable.
3)、It is the same as R-22 but better than R-502 in the warming capability.
4)、It doesn’t need change the main parts and line of the former refrigeration system for R-22 and R-502.
Thrr03a won the Chinese ENCOURAGEMENT FOR SCIENCE AND INVENTION in 2000 years and listed as the important environmental protection technique item by Chinese EPB and was accepted by SNAP plan of American EPB. It is an alternative replace to R-22 and R-502 which used in the business air-conditioning, industry cooling, the system of air-conditioner, transport cooling. |
