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.

Designed for high-efficiency heat pump and air conditioning systems, the new Copeland Scroll® variable-speed compressor allows heat pumps to achieve 13 HSPF, 20-plus SEER efficiency, and 40 percent greater year-round energy savings than standard heat pumps, says the company.

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.

Service technicians know that keeping compressors operating properly can present challenges, especially in supermarket refrigeration applications.

Replacing a compressor is neither simple for a technician nor inexpensive for the customer. Before replacing a compressor, a technician needs to ensure that it is truly defective. Unfortunately, sometimes good compressors get replaced as a result of a misdiagnosed problem.

As part of a renovation plan, Florida State College at Jacksonville researched a number of upgrade scenarios for its chiller plant. Initial recommendations for a conventional chiller failed to meet budget and energy-savings requirements. During the re-evaluation process, the college team visited Flagler College to see a chiller actually using the compressors.

Ask any fashionista and she’ll tell you her outfit is nothing without accessories. The winners in The NEWS’ eighth annual Dealer Design Awards’ Components and Accessories category know this to be true too, but they aren’t dealing in cheap jewelry and ridiculous shoes.
