AC-83-05-3 -- Development of a Residential Gas Absorption Heat Pump PDF

A residential absorption heat pump system has been developed based on a new absorption pair. This new system uses R123a (CC1₂FCHCIF) as the refrigerant and ETFE (ethyltetrahydrofurfylether) as the absorber. The properties of this new pair, when compared to an ideal pair, show they are quite satisfactory, especially for a heat pump application. The thermodynamic analysis of the new pair shows the potential of very good performance.

Actual tests show that heating Coefficients of Performance (COP) in the range of 1.50 are possible with the system. At that level of performance, the system is very competitive with other heating and cooling technologies especially in more northerly climates.
