These fractional-horsepower, low-temperature Copeland Scroll compressors utilize liquid-injection technology to cool discharge temperatures and reduce compressor stress while also meeting upcoming federal regulatory requirements.
Refrigeration service technicians often run service calls in which they find a compressor with a higher-than-normal suction pressure along with a lower-than-normal head pressure. Many times, the refrigeration equipment is still running, but the product temperature is too warm, which causes product quality and safety to suffer.
The capacity of a compressor can be affected by a refrigeration system’s ever-changing pressures. In addition, suction pressure entering the compressor will change the density of the suction gasses within the compressor and affect its capacity.
Members of The NEWS’ trainer panel examined compressor valves and determined the best methods for maintaining valves, diagnosing faulty ones, and implementing proper troubleshooting techniques when they go bad.
TG Series units are oil-free, variable-speed, magnetic-bearing, and centrifugal compressors. The compressors provide full- and part-load energy efficiency and feature a small footprint, light weight, low vibration, low sound, intelligent controls, and soft-starting characteristics.
Several leading compressor manufacturers weighed in with insights and advice for contractors and technicians as they learn how to work safely with the equipment utilizing these so-called alternative refrigerants as they transition into primary refrigerant choices.
