Danfoss, a manufacturer of high-efficiency electronic and mechanical components and controls for air-conditioning, heating, refrigeration, industrial, and water systems, recently conducted an online survey to gauge industry acceptance of CO2 refrigeration systems in North America.
In follow-up to the document that Tecumseh issued in January 2016 regarding recommended refrigerants, the company says it is making the required changes to its compressors and condensing units in order to meet the performance, reliability and safety requirements for use with alternatives to R-404A and R-134a refrigerants.
Of course, reclaimers can only reclaim what contractors and technicians recover, and while the R-22 numbers may never match the hoped-for projections, the industry is already looking to the future and preparing to address new challenges in a post-hydrochlorofluorocarbon (HCFC) world that also is likely facing a phasedown of hydrofluorocarbons (HFCs).
The Green Tech Line of refrigeration and air conditioning components is designed for use with natural refrigerants R-290 (propane), R-600a (isobutane), and R-744 (CO2). These high-quality, hydrocarbon (HC) and CO2-ready system components include valves, controllers, transducers, filter driers, and microchannel heat exchangers.
The Chemours Co., a global chemistry company in titanium technologies, fluoroproducts, and chemical solutions, announced that it has broken ground on a new HFO-1234yf production facility. The new facility, located at the Chemours Corpus Christi plant in Ingleside, Texas, will triple the company’s capacity for its HFO-1234yf-based-products, which are low-global warming potential (GWP) and better for the environment.
This line for hydrocarbon (HC) refrigerant (R290/R600a) use includes electronic expansion valves (EEVs), thermostatic expansion valves (TXVs), reversing valves, check valves, ball valves, and solenoid valves.
The VTC series compressor and electronic controller dynamically matches the capacity of the compressor to the cabinet’s cooling demand. The series features a capacity range from 300 to 1,500 Btu per hour, and is optimized for use with eco-friendly hydrocarbon (HC) refrigerant R-290 (propane).
New ice rinks generally use ammonia as a refrigerant, but R-22 was the choice for many years, and the ice making systems in older rinks can contain several thousand pounds of R-22. In the approaching cold, hard reality of a post-R-22 world, how will rinks keep their ice cold and hard?
