When hundreds of the top ammonia refrigeration engineers, manufacturers, contractors, and end users gather in one place, technical talk is sure to follow. Such was the case at the most recent International Institute of Ammonia Refrigeration (IIAR) Conference in Nashville, Tennessee.

This article, the second in a series, features important maintenance considerations in order to keep a refrigerant recovery unit operating properly. 

On May 27, 2014, the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) filed a petition for review in the U.S. Court of Appeals for the Seventh Circuit against the U.S. Department of Energy (DOE) in response to its final rule regarding energy conservation standards for commercial refrigeration equipment. 

The G-Series ½-6 horsepower (hp) outdoor condensing unit has been added to the company’s line of outdoor condensing unit products. The new series enhances serviceability while delivering operational efficiency gains for the end user. 

A while ago I took my wife to a bed and breakfast on a lake. It was an older place, but how they (mis-)treated one of the ice machines — which itself appeared to be pretty old — was something else.

The U.S. Department of Energy (DOE) has announced new energy efficiency standards for electric motors and for walk-in coolers and freezers. According to the DOE, these standards combined are expected to provide businesses with $26 billion in energy savings through 2030.

The goal of the project was to provide energy-efficient HVAC solutions that reduce the client’s energy costs while providing flexible cooling/heating options to a multi-tenant/multiuse facility.

Star Refrigeration Group announced that it has launched a new United States subsidiary, Azane Inc., to manufacture and supply its “low-charge ammonia” technology in the U.S. The company developed the technology to meet the challenges that the HVACR industry was facing as Europe started the phaseout of R-22 refrigerant.

Demand for commercial refrigeration equipment in the United States is forecast to increase 3.1 percent per year through 2018 to $10.7 billion, according to a new study from The Freedonia Group Inc., a Cleveland-based industry market research firm.
