The amendment, deemed the “Dubai Pathway,” is expected to be completed in 2016 and puts to rest an ongoing discussion regarding HFC usage that’s persisted among Montreal Protocol members for more than five years.
Emerson Climate Technologies Inc. addressed issues like the delisting of specific gases in certain applications and energy consumption reduction regulations at its E360 event held Sept. 3 at the Westin Dallas Fort Worth Airport Hotel in Dallas.
Association said it has long supported including HFC refrigerants in the phasedown plan
November 7, 2015
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) applauded the decision of the Parties of the Montreal Protocol (MP) to work toward an amendment in 2016 to include HFC refrigerants in the treaty’s purview, with a goal of working toward a schedule to phasedown their use across the globe.
At the just-completed 36th Montreal Protocol Open Ended Working Group (OEWG) meeting in Dubai, the Parties achieved agreement on a mandate for the contact group. This is a significant step towards amending the Protocol, a step which has not been achieved in at least six years.

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.
