Description

1 Cooling method of solar panel through fine atomization of fluid jet nozzle and solar panel cooling system using the same {COOLING APPARATUS FOR SOLAR PANEL USING FINE FOG OF SPRAY NOZZLE AND COOLING METHOD FOR SOLAR PANEL}

The present invention relates to a cooling device for a solar panel, which is provided at the lower portion of the solar panel and is capable of generating fine atomization with an injection nozzle capable of adjusting the front, rear, left and right angles. It relates to a solar panel cooling device through fine spraying.

The photovoltaic power generation system has many advantages, such as no waste or noise vibration, no secondary environmental pollution, and a lifespan over 20 years, resulting in low cost of operation and maintenance.

However, in reality, when a solar module converts solar energy into electrical energy, the efficiency is greatly changed by a given environment, and in particular, the effect of overheating of the module temperature has a significant effect on power generation efficiency.

In terms of international and domestic related standards, the efficiency is based on the solar module temperature of 25 ℃ and the insolation intensity of 1,000W / ㎡. When the surface temperature increases by 1 ℃, the power generation decrease of about 0.3 ~ 0.5% occurs. In particular, in Korea, there are many differences depending on the season. The temperature of the photovoltaic module rises to 60 ~ 90 ℃ until the beginning of June ~ September, which is the summer season. Shortening the service life can lead to serious economic losses.

In order to solve the deterioration caused by the temperature rise, in the case of the existing solar panel cooling technology, the cooling nozzle is configured to spray from the top of the solar panel to cool by using the temperature difference between water and the solar panel, so cooling efficiency is very high. It is low, and when a cooling nozzle is provided at the top of the photovoltaic panel, shadows are generated on the photovoltaic panel, resulting in a decrease in solar efficiency.

In addition, in the case of the existing solar panel cooling technology, a cooling fluid nozzle for cooling and a spray nozzle for cleaning the solar panel are provided in a two-fluid nozzle system. In the case of the two-fluid nozzle method, there is a problem in that the cooling efficiency of the solar panel is lowered due to more energy consumption than the one-fluid nozzle method.

According to a report from the Korea Institute of Industrial Technology, the Nano Pollution Control Lab. It can be made small. As an example, in steam humidification, 720 kW of energy is required to heat and evaporate water, but in a two-fluid waterless system, it is possible to use 80 kW as a compressed air power to refine water. (Table 1).

Way Energy consumption Remark Steam humidification 720.89 kWh 2 Fluid nozzle method 81.63 kWh (compressor) Compressor power per volume 0.15 kWh / N㎥ 1 Fluid nozzle method 2.22 kWh (high pressure pump) Pump pressure 6 MPa, pump efficiency 75%

First, the injection nozzle 200 is provided on the bottom or the ground of the solar panel 100 to spray the cooling solution for cooling the solar panel 100 in the form of fine particles. The cooling solution sprayed in the form of fine particles cools the solar panel 100 using evaporation heat that is evaporated by an external temperature. In the conventional case, as shown in Figure 1, the injection nozzle 200 is provided on the top of the photovoltaic panel 100, there is a problem that the energy efficiency by dropping the shadow on the photovoltaic panel 100.

When the first fluid is sprayed in a parabolic form, the time in the air increases, the contact time with the outside air increases, and the temperature increases, while the first fluid increases in phase in the form of water vapor near the solar panel 100. Heat exchange occurs efficiently with the solar panel 100.

The evaporation heat setting module 310 sets an appropriate evaporation heat value of the evaporated fine spray particles. Using the data synthesized by the spray nozzle sensor 460, the spray particle measurement sensor 450, the wind speed sensor 430, and the external temperature sensor 440, the solar panel 100 responds sensitively according to the external environment.

According to claim 4,
The cooling solution is selectively mixed with the washing solution and sprayed in the form of fine particles through the spray nozzle 200,
The cooling solution and the washing solution sprayed in the form of the fine particles are one fluid characterized in that cooling and washing can be simultaneously performed by cooling or washing the solar panel 100 using evaporation heat evaporated by the external temperature. Solar panel cooling method through fine spraying of spray nozzle.
