Description
Flat solar collectors are an economical option for use in domestic systems of water heating and heat supply.
They consist of a planar absorber (absorber), a glass coating (usually this is tempered glass with a low metal content), a heat-insulating layer on the reverse side, and a frame (most often of aluminum or sheet steel).
Advantages of flat collectors:
* simplicity of a design and installation;
* low initial cost;
* long service life;
* a large area of the working surface (surface that absorbs solar radiation);
* Absorbing element (absorber) catches 95% of the radiation;
* reliability (resistant to seasonal climatic phenomena);
* heat and waterproofing (a layer of mineral wool);
* installation using conventional materials for hot water supply.
A solar collector is a device for collecting the radiant energy of the Sun (solar power plant) carried by visible light and near infrared radiation and converting this energy into heat. When this occurs, the heating material is a coolant circulating in the collector.
Solar collectors are widely used in everyday life and in industry. They are used for hot water supply and heating of private houses, cottages, cottages, hotels, restaurants, temporary buildings, various industrial enterprises, sports complexes, children's institutions, hospitals, for heating water in swimming pools, etc.
