(1)、It is good in all the environmental protection characters
(2)、It is non-toxicity, non-inflammable.
(3)、It has higher speed in made cool, and can save energy
(4)、It doesn’t need change the parts and line of the former refrigeration system for R502 in the air-conditioning.
Thrr04 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 the special saving-energy refrigerant for the central air-condition system. It can be used in the business air-conditioning industry cooling, the system of transport cooling to replace R-502. |
