Abstract
A 37,85-m? (10,000 gallons) per year (nominal) passive solar-powered water distillation system has been installed and is operational in the Venus Deep Space Station at Goldstone, California. The system replaced an old, electrically powered water distiller. The distilled water produced with its high electrical resistivity is used to cool the sensitive microwave equipment. A detailed thermal model has been developed to simulate the performance of the distiller and study its sensitivity under varying environment and load conditions. The quasi-steady-state portion of the model is presented together with the formulas for heat and mass transfer coefficients used, Initial results indicated that a daily water evaporation efficiency of 30% can be achieved, A comparison made between a full day performance simulation and the actual field measurements gave good agreement between theory and experiment, which verified the model.
