Performance Analysis of Humidifying Dehumidifying Solar Desalination Unit

Abstract:

The Humidifying-Dehumidifying desalination unit with active heating and natural air cycling is studied in this paper. Each component is analyzed by energy balance. The instantaneous performances of unsteady heat transfer and mass transfer are calculated. Take midsummer and midwinter as represent, the air temperature in evaporator and condenser, seawater temperature in water box and water output in one day are calculated by program. The environment parameters, operating parameters affecting the output of unit are analyzed, and it's obtained that: the solar radiation intensity, atmosphere temperature are the main factors affect water output of the unit, well wind speed and the initial seawater quality in boxes hardly affect water output.
