Modelación Matemática de Sistemas de Calentamiento de Agua con Colectores Solares de Tubos Concéntricos.

Abstract

The investigation work on the mathematical modeling of water heating systems with solar collectors of concentric tubes of Project justification and objectivization; Physical variables were collected temperature and wind velocity, upon comparing the solar resource to the energy demand the solar panel area to be used is theoretically determined. In the mathematical modeling the optical and thermal factors are considered and the system efficacy is determined resulting in 71 a value considered to be high which pemnited the solar system standardization for water heating The standardization consists of determining the solar collector area in function of two variables user Number and available solar radiation, this standardization is for domestic and commercial uses with an incident radiation of 200 to 1000 Wrm significant values for Ecuador with the functioning tests of the solar collector, the water temperature variation in function of time was tabulated and illustrated the collector Efficiency for different radiation intensities is determined, comparative analysis in the matorials to be used for the isolator and reflecting plates was cartied out The equipment is paid in three years for a 4 people family with the use of 20o teroperature water per day and a tontperature Of 40 C with an area of 1.15 ii cost at 500 dollars
