The use of “green” energy supplied by natural disasters can significantly reduce utility costs. For example, by arranging solar heating of a private house, you will supply with virtually free heat carrier low temperature radiators and underfloor heating systems. Agree, this is already saving.
You will learn all about “green technologies” from the article we have proposed. With our help, you can easily understand the types of solar installations, methods of their construction and the specifics of operation. You will surely be interested in one of the popular options that are intensively working in the world, but not too much in demand in our country.
The review presented to your attention is disassembled design features systems, connection diagrams are described in detail. An example of calculating a solar heating circuit for assessing the realities of its construction is given. To help independent craftsmen, photo selections and videos are attached.
On average, 1 m 2 of the earth's surface receives 161 watts of solar energy per hour. Of course, at the equator, this figure will be many times higher than in the Arctic. In addition, the density of solar radiation depends on the season.
In the Moscow region, the intensity of solar radiation in December-January differs from May-July by more than five times. but modern systems so efficient that they can work almost everywhere on the earth.
On average over the year, depending on climatic conditions and latitude of the area, the solar radiation flux to the earth's surface ranges from 100 to 250 W / m2, reaching peak values at noon with a clear sky, in almost any (regardless of latitude) place, about 1,000 W / m 2. In the conditions of central Russia, solar radiation "brings" to the earth's surface energy equivalent to approximately 100-150 kg of fuel equivalent per m2 per year.
Mathematical modeling of the simplest solar water heating installation, carried out at the Institute high temperatures Russian Academy Sciences with the use of modern software and data of a typical meteorological weather showed that in the real climatic conditions of central Russia, it is advisable to use seasonal flat solar water heaters operating from March to September. For installation with area ratio solar collector to a storage tank volume of 2 m 2/100 l, the probability of daily heating of water during this period to a temperature of at least 37 ° C is 50-90%, to a temperature of at least 45 ° C - 30-70%, to a temperature of at least than 55 ° C - 20-60%. The maximum probabilities refer to the summer months.
"Your Solnechny Dom" develops, assembles and supplies, both with passive and active circulation of the coolant. You can find a description of these systems in the corresponding sections of our website. Orders and purchases are made through.
The question is often asked whether solar heating installations can be used for heating in Russia. On this occasion, written separate article- "Solar heating support"
