13 May Refrigerant Retrofit with Priority Cool®’s Product Performs Impressively
A refrigeration expert specializing in Green Energy solutions, gas retrofit and hydrocarbon refrigerants was pleasantly surprised to find that Priority Cool®’s product more than surpassed his expectations.
Mitch Byrne, president of Power Technology Chicago, Inc., had decided to experiment with a hydrocarbon refrigerant retrofit because the United States is coming under renewed pressure from the EPA and SNAP protocols to clamp down on the use of HCFC refrigerants and find suitable alternatives. Considered natural refrigerants, gasses like Hydrocarbon Refrigerant, CO2 and ammonia have become increasingly popular in Europe, he noted.
To see for himself, Byrne recently conducted a case study in which he replaced R134A refrigerant with Priority Cool®’s Hydrocarbon Gas called HC-12a/134+. He removed the older, ozone-depleting gas from refrigeration equipment and substituted Priority Cool®’s specially designed replacement, which runs at lower pressures and produces colder coils. This product has also been formulated to replace R12 gas.
Byrne used a standard side by side residential cooler/freezer to make the conversion for his case study.
“The results were very impressive,” Byrne notes. “The new gas performs far more efficiently while cooling as good as or better than the old refrigerant.”
First, he measured the amp draw at 1.3 amps and recorded the refrigerant’s low side pressure at 14 PSI. Then he recovered 5.8 ounces of the old gas from the unit. Next he removed the old filter drier and soldered a new one into the liquid line. For an hour the system was pulled into a deep vacuum. He charged in Priority Cool® Hydrocarbon gas HC-12a/134+ at only 35 percent of the original charge—2.03 ounces. He monitored the system for proper temperature and cycling and found that it held the temperature well. The amps dropped from 1.3 to 1 amp, a decrease of more than 23 percent. Just as significantly, the low side pressure dropped to 3 PSI.
“I now understand why this is such a hugely popular gas across Europe,” says Byrne. “The energy savings are substantial and, at the same time, I can see how reduced operating pressures could drastically prolong the life of the compressor and other critical system components.”
Byrne says he plans to convert many more domestic and commercial refrigeration units to Hydrocarbon Refrigerants over the summer and report back his findings.
