ATMOsphere America, a conference focusing on how natural refrigerants are being used in refrigeration, air conditioning, and heating systems, returns for its fifth edition, June 16 and 17, at the Westin Michigan Avenue in Chicago.
EOS Climate announced it has completed its first project to generate Verified Emission Reductions (VERs), also known as carbon credits, from the reclamation and reuse of hyrdofluorocarbon (HFC) refrigerants.
UK retailer Sainsbury’s has become the first customer to take delivery of Carrier Transicold’s prototype natural refrigerant trailer unit — a new generation of transport refrigeration system for trailers that operates exclusively with CO2 refrigerant.
The Chemours Co. announced it is investing in large-scale manufacturing to expand supply of its Opteon™ family of refrigerants. Chemours will invest $230 million over three years to construct a new facility at its Corpus Christi site in Ingleside, Texas, with start-up expected in the third quarter of 2018.
An undercharge of refrigerant will cause low head and suction pressures, but that is not the only thing that will cause both pressures to be low. An undercharge will have low condenser liquid subcooling readings on the high side, where a dirty air filter for the evaporator will not produce low condenser liquid subcooling readings.
The supermarket industry realized a long time ago that it is impossible to solve environmental problems related to refrigerant leaks using a repair-based approach (i.e., with policies that focus on leak repair and record-keeping). Yet, the U.S. Environmental Protection Agency’s (EPA’s) main regulatory program to address harmful refrigerant emissions reflects a repair-based policy.
The U.S. Environmental Protection Agency (EPA) is cautioning homeowners, HVAC contractors, and service technicians of the safety hazards related to recharging existing home air conditioning systems with a propane-based refrigerant.
California’s Air Resources Board (ARB) has released a proposed strategy aimed at curbing emissions of short-lived climate pollutants, including hydrofluorocarbons (HFCs). The proposal targets near term emission reductions that will help California meet its 2030 greenhouse gas reduction targets.
Compressor manufacturer Bitzer has approved the hydrofluoroolefin (HFO) refrigerants R-1234yf and R-1234ze(E) for its CSH and CSW screw compressors. The two alternatives to R-134a have a global warming potential (GWP) of less than 10.
Honeywell has entered into a supply agreement with a Chinese manufacturer to produce Honeywell Solstice® yf (HFO-1234yf), further extending its global supply base for this low-global warming potential (GWP) hydrofluoroolefin refrigerant.
