EMERSON CLIMATE TECHNOLOGIES PUBLISHES PAPER ON THE MEASURES OF REFRIGERATION SYSTEM PERFORMANCE

White Paper Introduces New, More Representative Measure for Refrigeration Applications

ST. LOUIS, December 21, 2007 – Emerson Climate Technologies, a business of Emerson (NYSE: EMR), announced today that the company has published a white paper for the commercial refrigeration industry. This paper, Annual Energy Efficiency Ratio: A Better Measure of Refrigeration System Performance, is the next white paper in Emerson Climate Technologies’ ongoing campaign to promote good industry policies and practices. It addresses the industry’s need for a more representative measure for refrigeration system performance.

“Our industry currently has measures in place to calculate the performance of commercial refrigeration systems; however, none of these measures fully address the various conditions that impact refrigeration systems,” said Rajan Rajendran, director of applications engineering for Emerson Climate Technologies, Inc., Refrigeration Division. “With the introduction of the Annual Energy Efficiency Ratio (AEER), Emerson Climate Technologies is proposing a new measure that truly addresses the industry’s needs.”

This white paper reviews the benefits and pitfalls of the Energy Efficiency Ratio (EER), the existing method for measuring the efficiency of refrigeration. The paper then introduces AEER, a new method that more accurately measures how a refrigeration system actually operates. Unlike EER, AEER takes seasonality into account, by analyzing a weighted average performance for a refrigeration system, using varying condensing temperatures tied to the actual weather data for a specific location.

Annual Energy Efficiency Ratio: A Better Measure of Refrigeration System Performance illustrates the positive impact of encouraging AEER measurement usage on the refrigeration industry as a whole. It provides an informative case study demonstrating EER versus AEER compressor evaluations and offers detailed appendices with term definitions, calculations and equations.
