ORANGEBURG, NEW YORK, October 15, 2018 — Daikin America provided 1,200 lbs. of Creard R-407H for a system conversion at the TOPS Friendly Market in Orangeburg, NY. The refrigerant will provide more than 25 cooling tons in medium-temperature refrigerated cases and displays. It has replaced R-22.
Daikin’s new Creard 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. Creard 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, sources report.
Customer Requirements and Results
The Daikin Engineering team worked closely with TOPS to address the following key requirements:
After the conversion from R-22 to Creard R-407H, the system was monitored for three months, from March through May, 2018. Throughout the test, data was collected related to operating pressures, temperatures, and the energy consumption of the system. The power consumption during the test months when compared to R-22 was 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 R-22 and R-407H.
TDH Refrigeration performed the retrofit during a single overnight shift, following traditional retrofit procedures.
“We followed the same conversion steps as with other commercially available retrofit refrigerants,” said Bob Randon, president, TDH Refrigeration. “The R-22 to R-407H 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.”
Customer Reaction Positive
Tim Bowen, TOPS Markets maintenance manager, stated: “Creard R-407H is and will be a great help to TOPS Markets’ bottom-line due to its energy efficiency, cost, and requiring minimal changes to our equipment. Since Creard R-407H has demonstrated to be a cost-effective, low-GWP match with R-22, this really becomes a great solution for TOPS Markets as we move forward with our conversion program this year.”
“We feel great about the choice of working with Daikin and Creard R-407H,” added Chris Watson, director of construction and maintenance for TOPS Markets. “And as far as helping the environment, there’s no comparison at all: Creard R-407H is clearly best in class.”
