Study of Absorption Cycle Heat Pump Based Heating Units and Their Potential in the UK (United Kingdom) Domestic Central Heating Market. Volume 3: Working Fluids

摘要

As part of a study of the absorption cycle heat pump and its potential in the UK domestic central heating market, this report describes an investigation of potential working fluids and working fluid pairs. A database of over 130 potential refrigerants, over 270 potential absorbents and over 500 possible pairings has been compiled. Physical and physiological property data have been sought for the fluids listed although for fluids other than those used in well known systems the data were scant particularly in relation to mixture properties. To enable design work to be conducted, property data tables were set up for six mixtures of the more well known fluids. In addition, a hypothetical fluid pair was 'constructed' with desirable but realistic properties to enable cost sensitivities to be explored at the design stage. Many data are required to complete the database and continued research may be desirable if further work on the absorption cycle heat pump is to be conducted.
