An experimental integrated absorption heat pump effluent purification system. Part II: operating on water/Carrol solutions

An experimental integrated absorption heat pump effluent purification system (IAHPEPS) was built and originally operated with water-lithium bromide as a working mixture. The experimental results of IAHPEPS operated with water-Carrol as a working mixture are presented. Tap water was used as effluent and distilled water was obtained after purification. Pure effluent production rates ranged between 1.2 and 4 kg h−1. The actual coefficient of performance (COP)A varied from 1.35 to 1.55. The heat pump effectiveness (HPE) varied from 0.74 to 0.82. The results from the small scale system indicate the likely results from industrial scale units which could be operated with low quality heat such as waste heat, solar or geothermal resources.
