EFFICIENCY ENHANCING SYSTEM FOR A PHOTOVOLTAIC POWER GENERATING FACILITY USING A TWO PHASE FLOW

摘要

The present invention relates to an efficiency enhancing system for a photovoltaic power generating facility. The efficiency enhancing system for a photovoltaic power generating facility according to the present invention maintains or enhances efficiency by spraying cooling water onto the photovoltaic power generating facility, which consists essentially of solar modules for collecting solar light and generating electricity, wherein the efficiency enhancing system comprises: a storage tank for storing the cooling water; a cooling water spraying means for spraying the cooling water onto the solar modules; and a pump for pumping the cooling water stored in the storage tank and supplying the pumped cooling water to the cooling water spraying means through a cooling water supply pipe. The cooling water spraying means comprises a Venturi pipe which generates negative pressure therein to introduce air from the outside. According to the above-described efficiency enhancing system for a photovoltaic power generating facility of the present invention, the Venturi pipe is employed to spray the outside air together with the cooling water, thereby enabling improved cooling and washing of the solar modules, and the consumption of the cooling water to be reduced, by means of a two phase flow.
