Daikin America has partnered with TOPS Friendly Markets to complete the first refrigeration conversion of a U.S. supermarket from R-22 to Creard R-407H refrigerant. At the TOPS store in Alden, NY, 1200 pounds of Creard R-407H has been used to provide more than 25 cooling tons in medium-temperature refrigerated cases and displays
Daikin's new Creard R-407H refrigerant is a low global-warming-potential (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 1380, one of the lowest GWP options for refrigeration systems, providing a combination of performance while being economical relative to the products it is replacing. This comes in response to regulations to phase out ozone-depleting substances resulting from the Montreal Protocol.
Daikin engineers worked closely with TOPS to address key requirements:
- A GWP of less than 1500 to position TOPS with a sustainable solution for the useful life of the equipment in the event of any future climate related regulatory policies.
- Equivalent or better energy efficiency and refrigeration capacity across the entire operating range.
- A close match in temperature, pressure, and volumetric flow rate properties to R-22, to use the same expansion devices, distribution system, and piping.
- Traditional chemistry, with proven material compatibility with legacy R-22 equipment.
- Cost-effectiveness in long-term operation.
Tim Bowen, TOPS Markets maintenance manager, states, "Creard R-407H is 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 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."
