Thermodynamic screening of some HFCs and HFEs for high-temperature heat pumps as alternatives to CFC-114.
Author(s) : DEVOTTA S., PENDYALA V. R.
Type of article: Article, IJR article
Summary
The theoretical performances of a few selected fluids, screened from about 30 hydrofluorocarbons and fluorinated ethers, have been comparatively assessed for high-temperature working fluids as alternatives to R114 by using some basic and derived heat-pump parameters for an ideal Rankine cycle including pressure ratio, specific compressor displacement and theoretical Rankine COP. The following fluids have been assessed: R134, R143, R236ca, R236cb, R236ea, R236fa, and R254cb. While all the fluids assessed offer better COP values, R143 offers the best values. Use of R143 necessitates better safety design, owing to its flammability. R134 also offers attractive COP values next to R143.
