A building energy-saving device based on photovoltaic technology

Abstract

The invention discloses a building energy-saving equipment based on photovoltaic technology, which belongs to the technical field of building energy-saving equipment. The device electrically controls the photovoltaic panel on the upper side of the air conditioner to perform 90° light irradiation detection through a controller, and at the same time, the data detection unit commands unit time to generate electricity Quantity detection and photovoltaic panel inclination detection will record the detected values ​​in the data recording unit, and the data screening unit will filter again to calculate the angle at which the photovoltaic panel is in the rotation process. Afterwards, the controller controls the photovoltaic panel to rotate to the most suitable angle to receive light at this time, so that the light intensity received in this time period is the largest, and at the same time, the controller detects the light on the photovoltaic panel again by controlling the data detection unit every one hour. The intensity of the surface of the panel is adjusted by adjusting the inclination angle of the photovoltaic panel so that the intensity of light shining on the photovoltaic panel is always at the maximum.

Description

technical field [0001] The invention relates to the technical field of building energy-saving equipment, more specifically, to a building energy-saving equipment based on photovoltaic technology. Background technique [0002] Comprehensive building energy saving is the sum of energy saving in every link during the whole life of the building. It refers to the use of energy-saving building materials, products and equipment, the implementation of building energy-saving standards, the strengthening of the operation and management of energy-saving equipment used in buildings, and the rational design of building enclosures in the process of site selection, planning, design, construction and use.

AI Technical Summary

Problems solved by technology

[0003] Building energy-saving equipment includes air-conditioning, lighting, hot water supply equipment and other equipment. At present, in the process of using building energy-saving air-conditioning, some air-conditioning equipment using photovoltaic technology has begun to be used, but the existing photovoltaic technology air-conditioning equipment is large Most of them can work when the photovoltaic panels can absorb sunlight. For example, some air conditioners placed on the roof, because the photovoltaic panels are generally fixed and cannot be moved due to the movement of the sun, resulting in photovoltaic panels and the sun after a certain period of time. The direction of the light is on the back side, which cannot absorb the light energy to generate electricity to work, and can only work through its own electricity. The energy consumption of such a building is still relatively large
