130-Ton unit in development
The Western Cooling Challenge (WCC) was developed by the Western Cooling Efficiency Center (WCEC) at UC Davis to “accelerate the development, commercialization, and market adoption of packaged air conditioners that are dramatically more energy efficient than current equipment” (Dr. Mark Modera, Director of the WCEC). The Challenge responds to requests from building owner and electric utility affiliate members of the WCEC, motivated by state and corporate goals for energy efficiency and sustainability. For example, the California Public Utility Commission’s Energy Efficiency Strategic Plan gives specific priority to the application of climate-appropriate cooling technologies.
Trane and ICI have partnered to develop the VoyagerDC® and PrecedentDC® packaged cooling series. A VoyagerDC unit was rigorously tested and qualified to WCC standards in July, 2012. Trane is the first major HVAC manufacturer to offer a Challenge-certified product line. Trane VoyagerDC and PrecedentDC units apply Integrated Comfort’s patented DualCool® technology to achieve Challenge-level performance. These pre-packaged units are ideal for new buildings and for replacement of older, lower efficiency rooftop units on existing buildings.
… one of the most cost effective ‘climate-appropriate’ cooling technologies available for commercial buildings.
As Jonathan Woolley of the WCEC comments, “Many are not yet aware that new electric utility rates will saddle commercial building owners with large additional charges for power used during peak periods. Since air conditioning is the largest portion of electricity used at these times, the potential for 40% savings is enormous. Trane’s Voyager DC met our performance goals on the mark, and promises to be one of the most cost effective ‘climate-appropriate’ cooling technologies available for commercial buildings”.
Trane and ICI have already produced WCC-qualifying pre-packaged rooftop units in sizes ranging from 10 tons (in the Trane Precedent line) up to a 40 ton Voyager DC. Future WCC Trane DC units are anticipated up to 130 tons. Trane VoyagerDC units are being monitored in the field by both PG&E and Southern California Edison.
