In this troubleshooting situation you are dealing with equipment that has only been in operation for two months. And during that time frame, the customer has complained that at times the box temperature is higher than it should be, but the unit then seems to recover and freeze OK.

The settlement is a victory for the manufacturers and contractors who may have been substantially harmed by the standards had they remained in place. Yet, many in the industry are concerned about the growing need to litigate in order to ensure regulations are developed properly and fairly.

With thousands of dollars of perishable product under refrigeration at any given time, restaurant owners and managers prize speed of service above all else from their refrigeration contractors. 

DOE has denied AHRI’s petition for reconsideration of walk-in standards. Is it getting harder to reach consensus on efficiency standards?

The DOE, AHRI asserts, did not follow proper protocol when promulgating the WICF final rule and issued energy-conservation standards that many in the industry feel are unfair, not technologically feasible, and unnecessarily burdensome to HVACR manufacturers.

The discussion will focus solely on the mechanics of measuring the relevant values and the downstream calculations needed to rate the efficiency of WICF refrigeration system basic models that are either sold as mixed or matched systems.

The U.S. Department of Energy (DOE) has issued a pre-publication Federal Register notice in response to the Air-Conditioning, Heating, and Refrigeration Institute’s (AHRI’s) petition for reconsideration of DOE’s final rule on energy efficiency standards for walk-in coolers and freezers (WICFs). DOE announced it is denying the petition.

On Aug. 4, the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) and Lennox Intl. Inc. filed a petition asking the U.S. Court of Appeals for the 5th Circuit to review the U.S. Department of Energy’s (DOE) final rule establishing energy conservation standards for walk-in coolers and freezers (WICF).
