The CoreSense™ Diagnostics electronics modules in Copeland Scroll® compressors unlock advanced capabilities in fixed-speed and two-stage compressors. Designed to help contractors troubleshoot residential air conditioning systems, the modules use the compressor as a sensor.
Time of use (TOU) rate structures have long been touted as a necessity for utility companies to incentivize homeowners and building owners enough to embrace demand response systems. According to John Galyen, president of Danfoss North America, “Smart meters will change the game.”
Low pumper compressors can be devilish to diagnose properly. None of us wants to replace a compressor that is not bad. With more than 40 years of experience, I want to offer some thoughts.
In recent months, Tecumseh Products Co. has made a number of announcements related to a line of refrigeration compressors that are optimized for HC refrigerants, an expansion of its line of large frame rotary compressors, and the introduction of direct current (dc) compressors.

Many servicemen experience service calls where the compressor has both a low head pressure and a high suction pressure. There are three main reasons why a compressor will simultaneously have a low head pressure and a high suction pressure.
Scroll compressors by the company for commercial and light commercial applications include R-410A, R-134A, R-407C, and R-22 fixed and variable-speed models.
Expansion of the company’s North American large-frame rotary compressor lineup includes new solutions for the residential, specialty, and industrial air conditioning markets.
Compressor electronics technology can enhance compressor and system performance by sensing and interpreting information found inside the compressor, providing new levels of protection and diagnostics.
The manufacturers creating new HVAC technologies are teaching others all about it.
