Performance and Exergy Analysis of Open Absorption Heat Pump

Abstract:

An open absorption heat pump(OAHP) in second type was built in this paper in order to recycle the heat and water from the flue gas. the coefficient of performance(COP) and the exergy efficiency were analyzed with the method of process simulation. Results showed the COP is 0.64, and latent heat recovery ratio is 19.6%. The temperature and humidity of flue gas, the temperature and flowrate of cooling water would influence on the COP. The increase of these parameters would lead to COP increase. The exergy efficiency of the system was 19.2%. The absorber, the generator and the condenser produce most exergy loss. The exergy efficiency of condensation was 0, which was using to recovery condensation water. The exergy efficiency would be strengthen by reducing the exergy loss of absorber and generator.
