Freezers and Coolers

RSS

CO₂ is primarily used in cascade systems that include ammonia, in booster systems in supermarkets, and as a stand-alone refrigerant for transcritical-configured systems.

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.

The Food Marketing Institute (FMI) Connect event showcased some of the newest products that those who work in the food sector will more than likely see on a future install or service call.

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).

Some forward-thinking businesses are employing tomorrow's refrigeration technology today. Here are a few examples.

Technicians need to to be aware that ice machine servicing expertise might be just one small part of the technology they could encounter on a single piece of refrigerated equipment. 

Some of the newest electronic technologies were on display at the 2014 National Restaurant Association Restaurant, Hotel-Motel Show.

Petitioners contend DOE didn’t take all stakeholder comments into account when promulgating the rule.
