Investigations of mathematical models in solar collectors

摘要

There has been prepared the calculations methods of heat productivity of sun collectors which enables to determine the expedient of maintenance of polymers in sun collectors in the temperature mode given for different region and climate conditions. Show that, thermo endurance - T_0 maybe using as characteristic of thermo endurance of optic materials. If heating flow, destruction temperature and internal surface temperature is measured during test, it is possible to determine value T_0 and other necessity characteristics. As a result of the taking test was lead to comparison evaluation of considered materials. Working range of heating flow and up level heating embark have been determined.
