A compressor designed for use with CO2 as the refrigerant was on display at the Tecumseh (www.tecumseh.com) booth. The EPACO2OL is designed for use in a number of applications, such as commercial refrigeration, air conditioning, heat pumps, and hot water. Officials described it as a prototype and said they were gauging OEM interest in the concept.
Other technology from Tecumseh included the Silensys®, an outdoor condensing unit for commercial applications from 1/2 to 3 hp, and the Navajo evaporative condensing unit, which consists of dual compressors and fans for optimal efficiency in low, medium, and high cabinet operations. The latter concept, said the company, allows for mixing and matching compressor displacement for each cabinet in the 1/2- to 2/3-hp range.
