Completed a commercial walk-in cooler refrigerant conversion for Abu Omar Halal in Austin, Texas. The existing refrigeration system was operating with R-422B refrigerant and was converted to R-448A for improved long-term serviceability and efficiency. The existing refrigerant was properly recovered, the liquid line filter drier was replaced, and the refrigeration system was evacuated to a deep vacuum to remove moisture and contaminants before charging with virgin R-448A refrigerant. After startup, refrigerant charge was carefully adjusted while monitoring operating pressures, superheat, and subcooling to ensure proper system performance. A new refrigerant identification label was installed, and final testing confirmed stable operation and proper box temperature before the equipment was returned to service.
