To obtain the heat content (enthalpy), it would be necessary to know both the pressure and temperature at this point and then use a thermal dynamic superheat table for this specific refrigerant.

Many single-phase compressors require a start capacitor to assist in starting the motor. These capacitors will occasionally fail, causing a compressor to fail to start.

From the introduction of scroll technology to the onset of variable speed, HVACR compressors have come a long way. Unequivocally, these aren’t your grandfather’s compressors.

Danfoss had a fruitful and satisfying 2018 AHR Expo. Not only was its Turbocor® TTH/TGH High Lift Compressor named the winner of the 2018 AHR Expo Innovation Awards in the Green Building category, the company also took home the coveted Product of the Year award.

LG Electronics USA Inc.’s Component Solutions division recently introduced three new compressors at the 2018 AHR Expo.

During a press conference at the 2018 AHR Expo, Doug Murdock, president and CEO, Tecumseh Products Co. LLC, said the company, both at the show and in the coming year, will continue to launch and innovate with products customers want.

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.

Brent Schroeder, group president, heating and air conditioning, Emerson’s Commercial and Residential Solutions platform, numerous other Emerson leaders, and a handful of local and state dignitaries were on hand to turn the first shovels of dirt for an expansion project on a site that currently employs approximately 1,700 people.

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.
