Leading in Efficiency and Reliability with
90.1.This new standard requires higher efficiencies than past technologies can deliver. It mandates higher efficiency levels for scroll water chillers in comparison to reciprocating chillers. In fact, energy efficiency is so paramount the US Federal Government has adopted standard 90.1. Federal Executive Order mandates energy consuming devices procured must be in the top 25% of their class. In the case of chillers, ASHRAE 90.1 is the product standard for measurement.
Risk. Not only has ASHRAE 90.1 been adopted by the US Federal Government, it’s expected to be adopted domestically, if not globally, in the future. Make sure that your chillers as well as your entire HVAC system complies, or you may be caught retrofitting your project with new equipment and paying extra design dollars if the code changes during construction.
Trane’s CGWF was designed with the end user’s requirements in mind. Efficiency and reliability were primary design concerns with this latest generation machine.
Efficiency
The energy efficiency of the scroll chiller results in energy costs lower than any other comparable chiller. Full load efficiencies are improved beyond reciprocating chillers, but part load efficiencies are simply unmatched by any other manufacturer.
Superior efficiencies are obtained by combining many of the traditional scroll chiller energy efficient features with the Trane scroll compressor technology. HERE’S HOW:
•Scroll compressor’s positive displacement design
•Dual refrigerant circuits
•Multiple compressors
•Optimum system design
•Reduced friction
•No valves
•Advanced heat transfer surfaces
Scroll Chiller Energy Usage Savings
Reliability
The Trane scroll chiller with many new improvements, now brings an exciting new compressor to the commercial market — the Trane scroll compressor. Trane has designed the scroll compressor to be a leader in reliability. HERE’S HOW:
•Simple design with 64 percent fewer parts than equal capacity reciprocating compressor.
•Scroll compliance allows liquid and dirt to pass through without damaging compressor (liquid slugging resistant).
•Advanced microelectronics protect both compressor and motor from typical electrical fault conditions.
•Scroll compressors have less than a third the torque variations of a reciprocating compressor.
•Years of laboratory testing have optimized compressor and chiller systems reliability.
