Heat Transfer and Optimization

The single effect evaporation desalination process combined with adsorption heat pump (ADVC) is modeled analyzed as a function of the system design and operating parameters. The analysis gives variations in the thermal performance ratio, the specific heat transfer area, and the specific flow rate of cooling water. The performance evaluation is made as a function of the brine boiling temperature, the difference in the temperature of the compressed vapor and the boiling brine, and the water content in the adsorption bed. Results show that the thermal performance ratio of this configuration is the highest among all single effect evaporation desalination systems. Moreover, the specific flow rate of the cooling water and the specific heat transfer area are similar to those of other single effect configurations. It should be stressed these promising features makes the ADVC system highly attractive to small and remote communities and of special interest in situations where energy cost is high.
