Precision Refrigeration will introduce a new refrigerant into selected models throughout this year after internal trials suggested it would deliver a greener performance than products it currently uses.
The company says it is putting its faith in Honeywell’s Solstice N40 refrigerant after it was introduced to the line by refrigerant distributor IDS Climalife.
Precision ran a comparative test with their existing refrigerant to see if Solstice N40 would be a greener alternative and it says the product came up trumps.
Solstice N40 is 100% non-ozone depleting, possesses low toxicity (ASHRAE class A) and is non-flammable (ASHRAE class 1), which makes it significantly safer in use than alternatives such as hydrocarbons and ammonia, according to Precision.
“We expect further performance improvements with gas charge expansion valve adjustments,” said Steve Goldsmith, refrigeration engineer at Precision. “Solstice N40, based on new hydro-fluoro-olefins, is an exciting new alternative refrigerant than gives us the opportunity to maintain our position as one of the country’s most innovative commercial refrigeration companies.”
Precision evaluated the temperature performance and energy consumption of one of its standard LCU323 three-door freezer counter cabinets using R404A against one using Solstice L40.
Temperature performance and energy consumption were tested to EN153 over a 24-hour period, with the cabinet empty of product and the door closed.
It found that Solstice N40 offers better refrigeration performance than R404A with a lower energy consumption. Precision said that Solstice N40 also exhibits lower recovery time after defrost and significantly better pull-down time alongside a reduction of about 65% in GWP over R404A.
