Refrigeration System Innovation

Abstract

Developmental research to design and fabricate the Refrigeration System Innovation, and to evaluate its efficiency on processing time, repair cost, operating cooling temperature, and operating current rating of the unit on removing, discharging, and refilling of lubricating oil as compared with adapting the Conventional Method (CM) and using the Original Refrigeration and Air-Conditioning (ORAC) Unit. The solenoid’s installation of the valve, access valves, and pressure switches interconnected functions with the original components of the system to ease the entire operation of discharging and refilling lubricating oils for maximum usage of the unit. Results revealed that the processing time of removing, discharging, and refilling the lubricating oil is six times faster; repair cost efficiency of 2 ¼ times lower; efficiency on operating cooling temperature was 10% improvement; efficiency in the operating current by 4% improvement. Adapting the RSI is a highly recommended HVAC-RT program to produce globally competitive RAC technicians
