8th IIR Gustav Lorentzen Conference on Natural Working Fluids

The proceedings of the 8th IIR Gustav Lorentzen Conference on Natural Working Fluids held in Copenhagen on 7-10 September 2008 comprise 130 papers. They provide a wealth of information on a broad range of natural refrigerants and their applications. Fifty papers deal with CO2, 15 are on heat pumps, 8 cover ammonia, 8 deal with hydrocarbons, 8 are on sorption and 10 deal with secondary refrigerants including two-phase and slurry technology.

Main topics covered include: hydrocarbons; microchannels; sorption; not-in-kind technologies; heat pumps; secondary refrigerants and slurries; CO2; ammonia; safety issues; and refrigerant combinations and novel fluids.

Refrigerant Cycle Data: Thermophysical Properties of
Refrigerants for Applications in Vapour-Compression Systems

The aim of this booklet is to give the most important thermophysical property data for a number of different refrigerants with applications to vapour-compression systems in an easily accessible form. Tables provided cover basic cycles at different evaporating and condensing temperatures, the pressure ratio, volumetric capacity and isentropic compression work. The coefficients of performance of cycles with isentropic compression are given, as is the thermodynamic efficiency of each cycle. Data given cover the following refrigerants: R-32, R-125, R-134a, R-152a, R-290, R-404A, R-407C, R-410A, R-507, R-508A, R-600a, R-717, R-744 and R-1270.
