Ongoing industrialization and food retail modernization efforts in many of the world’s developing countries, such as China and India, will help grow the global commercial refrigeration equipment market to $38 billion in 2018.
As California goes, so goes the rest of the country. That adage has often proved true especially when it comes to regulations related to refrigeration and refrigerants. The state's aggressive environmental and regulatory positions have caused the rest of the United States to monitor policy making and enforcement out West.
The U.S. Environmental Protection Agency (EPA) is considering changes to its Section 608 requirements for refrigerant handling, including technician certification. The changes being considered would subject HFC refrigerants to the same handling regulations that are currently imposed on CFCs and HCFCs.
The Modular Silicon Expansion Valve (MSEV) from DunAn Microstaq (DMQ) is a fast-responding electronic expansion valve that can be used in a variety of refrigeration applications, including display cases, freezers, and walk-in and reach-in coolers.
This case study documents one year of operating experience with a transcritical carbon dioxide (TC CO2) booster refrigeration system at Delhaize America’s Hannaford supermarket location in Turner, Maine. This store, which began operation in June 2013, is the first supermarket installation in the U.S. of a TC CO2 booster refrigeration system.
