IIR Rankine Conference 2020: Which alternative working fluids for ORC systems?
HFOs (hydrofluoroolefins), HCFOs (hydrochlorofluoroolefins) and hydrocarbons were the main alternatives to HFC245fa presented during the IIR Rankine Conference 2020.
Focus on the new refrigerant HCFO1224yd(z)
The Japanese chemicals manufacturer Asashi Glass Chemicals developed a new refrigerant as an alternative to R245fa.
R1234yf as a working fluid in Organic Rankine Cycle systems
A recent review article presented the use of HFO R1234yf and its mixtures in Organic Rankine Cycle (ORC) systems, namely in applications for waste heat recovery from internal...
Foam blowing agents: use of R1233zd(E) is expanding
Honeywell announced that TCL, one of China’s largest appliance manufacturers, selected HFO1233zd(E) as foam blowing agent in its domestic refrigerators.
Trends: compressors
- Global compressor sales JARN has published an extensive overview of compressor markets in 2009. On the whole, the compressor market has suffered from the decrease in the air-conditioning market (-2.9% compared with 2008). Sales of rotary...
The tax on HFCs officially adopted in France
French tax on HFCs, officially adopted on December 30, 2018, will enter into force in 2021. Companies can already get a 40% income tax discount if they use alternatives to HFCs.
US: HFO blowing agent approved by EPA
Honeywell recently announced that its new HFO-based Solstice Liquid Blowing Agent (LBA) had received final approval from EPA to be used in foam insulation in refrigerators and other applications in the US. Whirlpool Corporation will be the first...
Purdue conferences highlights: development of high-temperature heat pumps
High-temperature heat pumps are currently subject to intense R&D work, as illustrated by several papers presented at Purdue last year. All Purdue papers can now be downloaded from the Fridoc database.
