AQUECIMENTO SOLAR: Proteção mecânica e otimização do uso pela exposição controlada dos tubos coletores solares

Abstract

The present work was motivated by the perception that in days of great insolation the solar heating system pours water through the sigh in the form of steam, causing waste of water and bringing the system to a temperature above that recommended by the manufacturer of aquatherm and PPR pipes. The system analyzed in this research had coupled vacuum collectors and did not allow the solution normally adopted for these cases which is the mixture of hot and cold water selectively in two reservoirs. To solve the problem, a solution was thought to cover the collectors when the reservoir water would reach above a certain temperature and find out when the temperature reaches below a certain value, in addition, it should cover the collectors in the night time increasing the mechanical protection avoiding its unnecessary exposure. For such purpose was initially considered the use of arduino, temperature sensors of the type DS18B20, real time clock and LCD type display to present the information of temperature, however, following the current trend it was found that it could be used ESP8266 type module that would add internet capacity to the system. It was discovered platform called BLYNK that allows the control of Internet of Things devices in the cloud even without in-depth knowledge of mobile device programming or functioning of the internet.
