Abstract: This paper presents a dynamic thermal model based on DesignBuilder simulation software platform, for a simple office building model with an integrated ventilated PV façade/solar air collector system in climatic conditions of Bratislava, Slovakia. Thermodynamic simulation has been applied in order to express thermal performance of a ventilated PV façade coupled with phase change material through the whole reference year. Attention is focused on simplified approaches which capture the important elements of the problem. The results of simulation show that natural ventilation of PV façade with added phase change material have ability decrease temperatures of PV panel during extreme days more than 20 °C and shift time of peak temperature even more than 5 hours.

Abstract: Sneak circuit analysis technique is an important analytical tool that can promote the safety and reliability of the circuit control system. It applied to aerospace control engineering widely now. Comparing a thermal system and electric circuit system, the concept and method of sneak path analysis for complex thermal system are proposed by this paper. And the development and application vista of thermal system sneak path analysis and specific implementation are analysed.
