Calculation of temperature data from an automatic solar heat supply system

<p><span lang="EN-US">This paper calculates the temperature in an automated solar heat supply system. The study used automatic controller to monitor data of entire developed system has a flat collector, heat-insulating translucent glass, and double glazing with reduced pressure. coolant is made thin-walled corrugated stainless pipe. from flow heats liquid removed cold water siphon enters its place. There constant circulation heat, which increases transfer efficiency by eliminating additional partitions between panel thermal insulation. sensors that register using field-programmable gate array (FPGA) STM32, designed system, actuators include power relays. During experiment, it was found save energy 2% due use relays, significant impact on service life equipment.</span></p>
