The
energy of sun light falling on the surface of the drive
does not change completely to heat
energy. It comes from the loss of half
of the heat storage. Heat consumption carried
out in different ways. Radiation rays outside
air to a transparent substrate and on the
upper surface. Reasonable costs of
heat through the
bottom and edges of the drive.
To
find the job des creation requires two drive indicator - the amount of energy
absorption and heat consumption in the social en ironmen. Pro fib table energy
is determined by the differ en cebetween the energy absorption between the floe
woof heat to the environment.

To measure the amount of water entering the system drives tables hid a flow meter. Heat trans for fluid in the accumulator it turns out with

Conclusion
With this article can
be use full to determine the coefficient of heat and attempts
to work with the help of solar radiation intensity and determine the humidity in
