Whether or not HCs become major refrigerant players in the U.S. depends on who you talk to. Advocates point to extremely lower global warming potential, low cost, and a proven track record in Europe and Asia. Others see the flammability issue, A3 safety rating, and current building and fire codes limiting use to smaller applications.

While troubleshooting or installing refrigeration systems using a thermostatic expansion valve, it is a relatively common task to measure the superheat value of the refrigerant leaving the evaporator. However, there is a major consideration when using this measurement to analyze the operation of a system.

A study from Carel has tried to get a precise handle on supermarket refrigeration energy savings at various levels of upgrades and at the same time has assigned some new terminology to the steps — ‘traditional,’ ‘evolved,’ and ‘excellent.’

The use of ammonia as a refrigerant has been around for approximately 160 years, dating back to its first use in France in the 1850s. It first appeared in the United States in the 1860s when it was used for artificial ice production. Its latest uses are a testament to the growing popularity of ammonia refrigerants.

‘Tis the season more people pay attention to refrigeration — the natural kind.

Featuring a space-saving design, the Serenity Series Cubelet Ice Machine, FS-1500MLH-C, produces up to 830 pounds of chewable cubelet ice per 24 hours. The shallow depth provides easy access to the dispenser bin.

In the move to new refrigerants, while the seals, compression ratios, efficiency ratings, and other considerations were painstakingly engineered, other system components were taken for granted. So the refrigerants changed, but what about the standards governing products that transport and contain those refrigerants?

For applications such as cafes, executive offices, sports suites, kiosks, and outdoor kitchens, the GEMU090 undercounter Pearl Ice® ice machine is 15 inches wide, over 33 inches high, and over 22 inches deep.

In late 2010, Sprouts Farmers Market set out to meet the EPA’s most stringent GreenChill standards with construction of its Thousand Oaks, Calif., store. Sprouts tapped Hill Phoenix to design a refrigeration system that not only would be environmentally friendly, but also energy efficient and cost effective to install and maintain.

Many servicemen experience service calls where the compressor has both a low head pressure and a high suction pressure. There are three main reasons why a compressor will simultaneously have a low head pressure and a high suction pressure.
