Making ammonia work in traditional HFC territory, trying transcritical CO2 systems in ice rinks, and examining ways to apply refrigeration principles to heat transfer rates were just three topics of 13 papers (five in Spanish) presented at the most recent Industrial Refrigeration Conference and Expo.
Refrigerants Pose Potential Fire Hazard for Homeowners, Technicians
July 15, 2013
The EPA is currently investigating instances where propane has been marketed and used as a substitute for HCFC-22 (R-22), a widely used refrigerant in home air conditioning systems.
The Food Marketing Institute (FMI) Energy and Store Development Conference will be held Sept. 8-10 at the Hilton Baltimore in Baltimore. Highlighted educational sessions include Food Retailing 2013: Tomorrow’s Trends Delivered Today, Supermarket Energy Reduction Plans, and more.
The dramatic market shift away from HCFC-22 has given rise to a number of new refrigerant options for distributors to sell and technicians to use. The fastest-growing and most-troubling concern being reported today is the practice of mixing alternative refrigerants with R-22.
Fluorocarbon Industry Yields Goods and Services in Billions of Dollars
July 15, 2013
The Alliance for Responsible Atmospheric Policy (Alliance), an industry coalition, has released a report detailing that the U.S. fluorocarbon industry’s total annual sale of goods and services amounts to $158 billion.
Unapproved Propane-Containing Refrigerants Pose Fire and Explosion Risk
July 2, 2013
The U.S. Environmental Protection Agency (EPA) is warning HVAC technicians, home improvement contractors, propane manufacturers and sellers, and homeowners of the potential safety hazards related to the use of propane or other unapproved refrigerants in residential air conditioning systems.
The road to wider use of HC refrigerants remains a rocky one — although it is still being navigated. The latest developments involve more revisions to the regulatory landscape, the tweaking of a refrigerant mix to make it more energy efficient in certain applications, and, as always, warnings about flammability.
Refrigerant Contains 'Extremely Flammable' Mixture of Propane and Isobutene
July 1, 2013
HRAI released a statement revealing that fire services could be at an additional risk when responding if the building has a highly flammable hydrocarbon refrigerant in its air conditioning system.
R-1234yf Refrigerant Is Determined to be Safe to Use
June 24, 2013
Utilizing input from Daimler, SAE International initiated additional safety research looking at R-1234yf, a new low global warming potential (GWP) refrigerant that can be used in automotive applications. SAE said its original risk assessment is still valid: risks are well below the risks commonly viewed as acceptable.
