Description

  The present invention relates to an apparatus for improving the efficiency of a photovoltaic power generation facility provided with a two-phase flow generating nozzle, and in particular, it is easy to adjust the left-right rotation angle, so that the injection efficiency can be increased to contribute to the efficiency improvement of the photovoltaic power generation facility. It is related with the efficiency improvement apparatus of the photovoltaic power generation equipment provided with the made two-phase flow generation nozzle.

  Unlike existing energy sources such as fossil raw materials, sunlight is a clean energy source that has no dangers of greenhouse gas emissions, noise, and environmental destruction that induce global warming, and is not at risk of exhaustion. Unlike other wind power and sea power, solar power generation equipment has the advantage of being free to install and cheap to maintain.

  However, in the case of the most widely used silicon solar cell, an output decrease of 0.5% occurs every time the temperature of the solar module increases by 1 ° C.

  Because of this characteristic, the output of photovoltaic power generation recorded the highest value in the spring and autumn instead of in the summer when the sun was the longest, and such a temperature rise is the main cause of reducing the power generation efficiency of photovoltaic power generation .

  In addition, such a solar module has a disadvantage in that dirt is likely to accumulate on the solar cell plate due to weather phenomena such as yellow sand and bad weather.

  When dirt accumulates in the solar module, the light absorption rate of the solar module is significantly reduced, so that the power generation efficiency can also be reduced.

  In addition, when rain or snow falls on the solar cell plate in winter, the power generation efficiency may be reduced.

  In order to prevent a decrease in power generation efficiency due to such dirt, snow, and rain, an efficiency improvement facility (maintenance facility) for solar power generation facilities is used.

  The efficiency improvement equipment of the photovoltaic power generation equipment has a function of cooling down the temperature of the solar module, and cleaning and removing dirt, snow, rain, etc. accumulated on the solar cell plate, so that the solar module has a constant output. It fulfills the function of maintaining and managing solar power generation equipment so that it can generate electricity.

  If the cooling effect on the solar module of the efficiency improvement facility of the solar power generation facility is not smooth or the cleaning action of the solar battery plate is not smooth, the output of the solar module is reduced.

  In order to solve this problem, the present applicant has already filed “Registered Solar Power Generation Efficiency Improvement Device” (hereinafter referred to as “Prior Art 1”) of Korean Registered Patent No. 10-0914965 and Korean Registered Patent No. No. 10-1326240 “Two-phase flow generation nozzle and efficiency improvement equipment of solar power generation equipment using the nozzle” (hereinafter, “preceding 2”).

  However, in the preceding 1 and the preceding 2, the entire apparatus has to be disassembled and assembled in order to adjust the right and left rotation angle of the injection nozzle, which is troublesome. In the preceding 2, the air inflow path from the outside is insufficient, and the injection There was a problem that efficiency decreased somewhat.

  In addition, in the preceding 1, the rotation opening / closing unit 400 provided for changing the path through which the cooling water flows has a large number of parts including the elastic spring 433, so that assembly, fastening and installation are inconvenient. There was a problem.
