Refrigerants

The Research and Technology (R&T) Committee of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has established a Flammable Refrigerants Subcommittee that will seek to develop a set of application requirements for the use of ASHRAE-designated 2L, or mildly flammable, refrigerants.

In many ways, refrigerant recovery and reclamation is an example of human ingenuity at its best. An innovative and essential product is created, and then a way is devised to prolong its usefulness by collecting it after years of service, purifying it, and using it again.

The ongoing phaseout of hydrochlorofluorocarbons (HCFCs), such as R-22, holds many unknowns for the HVACR industry as 2020 approaches, but at least one sector of the industry anticipates tremendous opportunity: the reclamation sector. 

Recovering refrigerant from HVAC and refrigeration systems is an important day-to-day task for HVACR technicians. Here’s a look at some of the latest tools that help make this important job easy, along with tips from the recovery equipment manufacturers on how to efficiently and safely recover refrigerant.

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.

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.

The first United States ice rink to use CO2 refrigeration is benefiting from lower operational costs and reduced environmental impact just two months after opening.

The EPA announced it’s increasing the options for refrigerants used in various types of refrigeration and air conditioning equipment in the U.S. to offer alternatives with low global warming potential.
