IIR documentSummary
The mathematical model of evaporating tower (ET) in heat pump air circulation evaporation separation (HP-ACES) system was built and the effect of inlet solution and air parameters on the heat and mass transfer characteristics of ET was investigated. Results shows that inlet solution parameters have greater effect on the total heat transfer capacity of ET than inlet air parameters. The total heat transfer capacity increases 4.2kW and 3.85 kW with the increase in inlet solution temperature and mass flow, respectively. The inlet solution and air temperatures and solution mass flow are beneficial to the thermal efficiency of ET while inlet solution temperature and dry air mass flow per unit cross-sectional area have negative effect on the concentrating efficiency of ET. Additionally, inlet solution temperature and dry air mass flow have negative effect on the concentrating efficiency.
