The pendulum in terms of ice machines has been swinging back and forth between complex to basic systems. Sometimes the trend was to the complex with detailed diagnostics. The swing to basic brought simple systems designed to run efficiently. But now there is a new level of up front high tech developments to make things simpler down the line.
Aside from the fact that an entire separate section of McCormick Place was turned into a tasting room for the International Wine, Spirits, and Beer Event, the main floor at the National Restaurant Association expo had a number of exhibitors showing ways to deal with an apparent growing interest in wine.
When a refrigeration system fails, many times the cause can easily be diagnosed.

Top topics these days for people involved in the food retail sector are energy, sustainability, and compliance and how to discuss those with decision makers within that sector. Data plays a significant role in selling an energy project. Once the project is sold and installed, we need to deliver proof of savings.

A sign at one of the booths at the National Restaurant Association Show stated: “Being on the Food Page is Good. Being on the Front Page is Bad.” That concern was certainly the focus of the refrigeration-related exhibitors where drink and food safety were reflected in the quality of ice and the effectiveness of freezers and coolers.
After 85 years, it takes more than cosmetics to keep a publication fresh; the right attitude needs to permeate the organization. “This publication, The NEWS, was started by my great-grandfather in 1926,” said BNP Media co-CEO Taggart Henderson.
History, they say, repeats itself. The HVACR industry is not immune to the truth of this saying. A good case in point was the introduction of R-410A earlier this century, compared to the introduction of R-22 in the 1930s.
We all create our own individual histories every day. At the same time, we become part of a larger history. With that in mind, we asked a few industry colleagues what the most significant changes were that they have witnessed in the HVACR industry.
Honeywell has announced that Bitzer has approved the use of HFC-407F (marketed by Honeywell as Genetron® Performax™ LT refrigerant in North America) as an HCFC-22 retrofit solution for medium-temperature systems, such as supermarket refrigerated cases.
