Evaporative cooling air conditioning system for photovoltaic power plant cooling and dust removing

Abstract

The present invention discloses an evaporative cooling air conditioning system for photovoltaic power plant cooling and dust removing. The system comprises an evaporative cooling unit and a power drive unit. The evaporative cooling unit is connected to a photovoltaic cell water spraying unit and an air cooling unit which are arranged to face the photovoltaic cell in a photovoltaic power plant. The power drive unit is connected to an evaporative cooling unit, the air cooling unit and the photovoltaic cell. According to the evaporative cooling air conditioning system, the evaporative cooling technology is applied to the photovoltaic power plant, the effective cooling of a photovoltaic cell is realized, the dust at the surface of the photovoltaic cell can be removed, and the power generation efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration, and in particular relates to an evaporative cooling air-conditioning system for photovoltaic power station cooling and dust removal. Background technique [0002] With the promotion and application of renewable energy in the country, photovoltaic power generation has become a green and environmentally friendly form of power generation, but the power generation efficiency of photovoltaic cells is easily affected by various factors such as outdoor light intensity, outdoor temperature and dust. [0003] For grid-connected large-scale photovoltaic power plants, because photovoltaic cells are exposed to sunlight for a long time, they are prone to accumulate dust, and it is more troublesome to clean and remove dust. The power generation efficiency should be reduced by about 0.5%. It can be seen that it is very necessary to cool down the photovoltaic cells. [0004] For the p...

Problems solved by technology

[0002] With the promotion and application of renewable energy in the country, photovoltaic power generation has become a green and environmentally friendly form of power generation, but the power generation efficiency of photovoltaic cells is easily affected by various factors such as outdoor light intensity, outdoor temperature and dust.

[0003] For grid-connected large-scale photovoltaic power plants, because photovoltaic cells are exposed to sunlight for a long time, they are prone to accumulate dust, and it is more troublesome to clean and remove dust. The power generation efficiency should be reduced by about 0.5%. It can be seen that it is very necessary to cool down the photovoltaic cells

[0004] For the problem of how to cool photovoltaic cells, most of them use mechanical refrigeration at present. However, using mechanical refrigeration to cool photovoltaic power plants not only requires a large investment but also consumes a lot of energy.
