Specifications:

s new  R-407H refrigerant is an economical, low GWP blend designed for new refrigeration systems and as a replacement for R-22, R-404A, and R-507 in existing systems.  R-407H has a GWP of 1,380 (Assessment Report 5), one of the lowest GWP options for refrigeration systems, providing a unique combination of outstanding performance while being economical relative to the products it is replacing.

 R407H is a blend of R134a, R32 and R125. It has a GWP of 1495, compared to R22's GWP of 1810.

After the conversion from R22, the system was monitored for three months (March through May, 2018). Data was collected for operating pressures, temperatures, and the energy consumption of the system. Power consumption during the test months when compared to R22 was reported to be 2% higher after the first fill and system shakedown, and then improved to 0.5% lower energy consumption after the controller was tuned. The cooling capacity remained the same between R22 and R407H.

"We followed the same conversion steps as with other commercially available retrofit refrigerants," said Bob Randon, TDH Refrigeration's president. "The R22 to R407H refrigerant conversion was completed with only a few adjustments required at system EPR valves. Monitoring of equipment operation and product temperatures post conversion have provided good results."

Tim Bowen, TOPS Markets maintenance manager, indicated that R407H had proven to  be a cost-effective, low-GWP match with R22. "This really becomes a great solution for TOPS Markets as we move forward with our conversion programme this year," he said.
