Approximate method for calculation of the air temperature when leaving the heat storage in solar heathouses

Solar energy is one of the rapidly developing branches of science, engineering and technology. The basis of such development is the creation and improvement of highly efficient power plants for converting solar energy into heat and electricity. Today's solar systems are already cost-effective, reliable and easy to operate. Their use is gaining popularity in developed countries. It becomes not only economical, but also prestigious. According to the literature [1,2], solar systems can save fuel and energy resources up to 60-70% or more.
