Honeywell’s refrigerant Solstice® N71 (R-471A) | Long-term, safe, efficient & reliable solution for large retail stores

Honeywell’s new refrigerant Solstice® N71 (R-471A) is non-flammable, ASHRAE-class A1, HFO-based with a GWP of 148 suitable for medium-temperature applications. Its unique combination of features makes it a compelling solution for large food retail stores, where the implementation of flammable refrigerants in larger volumes or high-pressure refrigerants represent a safety challenge in commissioning, operation, and maintenance activities.

Consequently, opting for a low-pressure, non-flammable refrigerant circulating through display cabinets to keep food products at the right temperature is the best guarantee of people’s safety. Solstice® N71 (R-471A) will allow existing installations to be upgraded to a long-term refrigeration solution, at significantly reduced investment cost and carbon footprint The high efficiency of Solstice® N71 (R-471A) will also contribute to reducing end users’ need for energy and their electricity bills.

Overall, the performance of the refrigeration systems does impact on the cost-to-serve for food retailers. The recent soaring of electricity prices, and the current geopolitical challenges of containing the carbon footprint of electricity production, speak in favor of high-performance HFO refrigeration systems. Finally, the quality of refrigerated food products can only be guaranteed by a reliable refrigeration system, able to run under challenging conditions like high ambient temperatures in the summer season. Thanks to their high critical temperature, HFO refrigerants allow systems to perform efficiently and reliably also at high ambient temperatures. In our presentation, we will review the properties and applications of the new refrigerant Honeywell’s Solstice® N71 (R-471A).
