Mostra Convegno Confirms the Large Chiller Market is Ready for R1234ze
Large sized chillers featuring Danfoss Turbocor centrifugal compressors using R1234ze were noticeably present at Mostra Convegno this year.
The recent Mostra Convegno in Milan highlighted a significant acceptance of R1234ze as a standard refrigerant in large chillers. Oil-free technology and Danfoss Turbocor compressors showed clear leadership in this segment and a growing presence at the fair.
Several large chillers were highlighted as being ready for R1234ze and no fewer than seven OEMs* were showcasing oil-free chillers equipped with Danfoss newest compressor, the TG310. The high visibility of large chillers with R1234ze confirms the industry has accepted HFOs as the future low GWP refrigerant for chillers of these types.
“It is a very pleasing reassurance of our low GWP strategy”, says David Williamson, sales leader Europe and Middle East for Danfoss Turbocor Compressors. “When HFO 1234ze first came to the market, many people were questioning the market acceptance of HFO due to the light flammability. It is not questioned anymore. The industry is now at ease with a mature compressor technology for superior full and part-load efficiencies and can now also reduce the GWP thus the overall carbon footprint”, he adds.
With fast growing demand, Danfoss customers are in safe hands. The company is well-positioned with a broad portfolio of oil-free components approved for R1234ze including expansion valves, system protections and heat exchangers to complement the TG310; therefore, helping OEMs rapidly transition to this HFO in a broad range of applications, both industrial and commercial.
The availability of HFO refrigerants also gives facility supervisors a long term solution to the management of cooling equipment, even in retrofit configurations. The cooling capacity is lowered by about 25% with an equivalent chiller using R134a but the energy efficiency is slightly increased.
“We anticipate the demand will increase still further when we will extend the TG model range using HFO. In the coming months, we will offer compressors that can either operate with R134a, R1234ze or HFO blends”, concludes Williamson.
