The U.S. Department of Energy’s (DOE’s) Fuel Cell Technologies Program will host a webinar with the Clean Energy States Alliance and the Technology Transition Corp. titled “Fuel Cells for Supermarkets” on April 4 from 1 to 2 p.m. Eastern time. The webinar will detail the experiences that supermarkets in four states have had with stationary fuel cells.

The need for energy efficiency and the desire for intelligent energy efficiency have created a hunger for data. This trend started 10 years ago (or more) in the building controls industry and is now being seen in the refrigeration controls sector.

It is a familiar lament for those who work on supermarket refrigeration. There is a problem. The owner wants it fixed immediately. The technician can apply a quick fix, but that won’t deal with potential recurring problems - and the fact that the equipment may not be operating all that efficiently or even be all that up-to-date.

Anthony, a manufacturer of glass refrigerator and freezer doors as well as display cases, has announced that it has completed a licensing agreement with Glacier, a maker of beverage doors and package doors for commercial refrigeration systems. Anthony is a portfolio company of Aurora Capital Group and Glacier is a business unit of Universal Industries.

This article explores how a restricted metering device will affect system performance and efficiency. The system is a commercial refrigeration system with a TXV as the metering device. The refrigerant being used is HFC-134a. Very similar results will occur if an automatic expansion valve (AXV) is used.

The actual frequency and tasks performed will vary from system to system. However, here are some generic maintenance tasks which can be applied to many refrigeration systems. These tasks can be divided into two groups: one for maintaining the cabinet and one for maintaining the refrigeration system.
