Last month’s article covered a 400-series refrigerant blend’s total temperature glide, effective temperature glide, fractionation, superheat, subcooling, and average evaporator and condensing temperatures using a pressure/temperature chart. This article deals with system pressure drops and net temperature glide in a refrigeration and/or air conditioning system.
Operators of facilities that use ammonia refrigeration equipment must write and enforce standard operating procedures, buy the proper personal protective equipment (PPE), and practice what they preach with regard to safety — not only from top to bottom in their own organizations, but also with visitors, contractors, and other industry stakeholders.
Danfoss' 25th EnVisioneering Symposium, “Refrigerants2Sustainability: Risks, Options, & Opportunities in Commercial Refrigeration,” addressed how an increasing industry-wide focus on refrigerants and energy is driving changes in the design, deployment, and maintenance of refrigeration equipment and supermarkets.
The U.S. Environmental Protection Agency (EPA) has released a pre-publication version of a proposal to expand and amend the National Recycling and Emission Reduction Program, also known as the Section 608 program, which governs the handling, use, and sale of ozone-depleting (ODS) compounds used as refrigerants.
Honeywell’s Solstice®N40 (R-448A) refrigerant for supermarket refrigeration has been named a finalist for the R&D 100 Awards. The R&D 100 Awards, sponsored by R&D Magazine, honor the 100 most innovative technologies and services of the past year.
A-Gas Americas has acquired Refri-Claim, an EPA-certified reclaimer, from ICOR International. The acquisition includes all the assets of the existing Refri-Claim business.
The recent refrigerant delistings made under the U.S. Environmental Protection Agency’s (EPA’s) Significant New Alternatives Policy (SNAP) program have made some customers — especially in the supermarket refrigeration sector — skittish about making a major investment in new refrigeration equipment.

HVACR industry leaders and White House officials gathered today at the Eisenhower Executive Office Building in Washington, District of Columbia, to reaffirm their 2014 pledge to invest $5 billion over 10 years in the research, development, and commercialization of low-GWP (global warming potential) refrigerants.
At a White House Industry Leader Roundtable today, the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) provided a progress report on its 2014 pledge to invest $5 billion in research over the next 10 years for new refrigerants and HVACR equipment to support energy efficiency.
