Big Box Retailer Goes Outside the Box
Big Box Retailer Goes Outside the Box Macy's recently completed a major store remodel in Walnut Creek, California that merged three independent buildings into a single new facility. While the new department store looked great, the existing R-22 reciprocating compressors had become an unreliable maintenance and energy expense—negatively impacting the profitability and performance of this otherwise revitalized retail outlet. A down economy and an already tight retail market encouraged one of America's oldest, most famous retailers to explore a new cutting-edge Danfoss Turbocor air conditioning solution.

Flagler College Uses Two Chillers For Superior Performance
Flagler's New Wave Of TechnologyA young college in an old town chose Danfoss Turbocor technology to help solve energy, humidity, and noise problems during recent building renovations. Flagler College in St. Augustine, Florida combined a chiller from McQuay International (a large Danfoss Turbocor customer) with mechanical services by a W. W. Gay Mechanical Contractors (a Danfoss Turbocor network contractor, Jacksonville, Florida) to provide cooling at a primary classroom building. This first chiller so impressed the owner that they opted to buy a second one for an art building renovation.

New Compressor Technology Retrofit for Operating Engineers Trust Fund Building
New Compressor Technology Retrofit for Operating Engineers Trust Fund BuildingThe Operating Engineers Pension Trust, Local 12 out of Pasadena, CA, was looking for efficiency improvements for their HVAC system. They became particularly interested in refrigeration compressor improvements and installed two new low-friction, oil-free refrigeration compressors developed by Danfoss Turbocor. The newly installed Turbocor compressors have opened the door to additional cooling savings, predicted to be as high as 50 to 70 percent vs. their older compressors.

Retrofit of an Air-Cooled Chiller with an Oil-Less Centrifugal Compressor
County of San Diego's East County Family Resource Center Case StudyThe County of San Diego's East County Family Resource Center is a 22,000 sq ft office facility served by one 88-ton York air-cooled chiller (230 Volt, R-22) with two reciprocating compressors. The chiller had been riddled with problems since installation: compressor failures, excessive noise, and significant oil in the refrigerant. In April 2005, one of the reciprocating compressors failed again; the replacement cost was estimated to be $12,800. Rather than replace the compressor like for like, the chiller was retrofitted with one R-134a 80-ton oil-less centrifugal Turbocor compressor, a transformer to step the voltage from 230V to 480V, an electronic expansion valve (EXV), and a variable frequency drive to control the two condenser fans.

Advanced Compressor Technology Solves Retrofit Problem
Sinclair Case StudyKeith Sinclair had a problem. He owned an attractive and ideally located office building in South Pasadena, in Los Angeles County. The five-story building at 1499 Huntington Drive had 28,000 square feet of rentable office space, and Sinclair’s goal was to keep it rented. But in recent years, a failing comfort system was causing occasional building cooling failures, and the rising costs of system maintenance were cutting into the profitability of the building. He needed a change. The solution he selected is one from which others in the same situation can learn and profit.

Technology Brief...The Danfoss Turbocor Compressor
Chiller InstallationThe California State Railroad Museum, located in Old Sacramento, is a complex of historic buildings and unique attractions for visitors of all ages. The museum features lavishly restored trains, engaging exhibits, and special events throughout the year.

In order to preserve precious artifacts, museums are often required to provide climate-controlled space 24 hours per day, 365 days per year in their exhibit halls. Unfortunately, this requirement often translates to high energy and maintenance costs.

Faced with skyrocketing maintenance costs and budget shortfalls, the museum decided to replace its existing 360-ton, centrifugal chiller with two, 160-ton, McQuay chillers equipped with Turbocor centrifugal compressors. The new chillers were installed in the summer of 2004 and are expected to save the museum over $25,000 in annual energy costs alone. The site will also serve as a demonstration site for this new technology.
