Choosing An Efficient Heat Accumulator For Solar Air Heating Collectors With Flat Reflectors

Abstract

In the countries of the world, the energy problem is becoming global, and there is a need to rebuild the energy base and find ways to use environmentally friendly renewable energy sources. In this article, the author has researched the process of using efficient thermal accumulators to increase the energy efficiency of the solar air heating collector. There are various ways to solve this problem, and it is the use of solar air heating collectors in autonomous energy supply systems, and the author proposed an energy-efficient thermal scheme of a solar air heating collector with a flat reflector with a heat accumulator. The method of using different heat accumulators was used to increase the energy efficiency of the solar air heating collector with a flat reflector with a heat accumulator, and the energy efficiency of using pyrolysis liquid and paraffin with heat-technical parameters close to the water as a heat accumulator was also shown. The created solar air heating device with a flat reflector with a heat accumulator can be used in autonomous heat supply systems, which allows for covering 60% of the heat load during the year in the climatic conditions of the city of Karshi.
