INITIAL EXPERIMENT RESULTS ON THE RESEARCH OF PROTOTYPE FRESHWATER DISTILLATION EQUIPMENT WITH HIGH EFFICIENCY

Tóm tắt

Distilling freshwater using solar energy is a promising way for sustainable development since the energy used is free and clean [1],[2],[3]. In this paper, the freshwater distillation equipment using a parabolic concentrated solar collector has been experimentally studied. The experimental system consists of a parabolic concentrated solar collector with 1.3m in diameter and 0.45m in depth. The material of reflective surface’s parabolic collector is Inox so that it can reflect solar radiation. The parabolic type\'s solar collector is adjusted according to the movement of the Sun every 15 minutes so that the reflective surface of parabolic is perpendicular to the solar radiation. At the focal point of the parabolic collector mount the freshwater distillation equipment. Performance of the freshwater distillation equipment using a parabolic concentrated solar collector is tested under the local conditions of Định Quán, Đồng Nai Province from 13/6/2012 to 30/11/2012. The experiment shows that, the influence of the solar radiation and wind speed on a capacity of the equipment. The capacity of this equipment can range from 6 to 8 L/day of fresh water from 8 AM to 4 PM.
