Study on the Energetic Parameters in a Photothermic Sensor with Black Polymeric Film

Abstract

In this paper the design of sensor photothermic prototype with polymeric film absorbing, the materials  radiation properties, the analysis of different energy losses in the system and the energy balance will be presented. The evolution of incidental solar illumination on the horizontal plan of sensor and the temperature distribution are studied. Results showed that the temperature obtained by thermal conversion depends on the absorbing characteristics of the polymeric film, radiation intensity and time exposure.

Keywords: film, solar energy, greenhouse effect, design, radiation, illumination.
