PERFORMANCE SIMULATION OF A HYBRID, PV/AIR HEATING WALL

摘要

The main objective of this work was the development of a software tool enabling potential manufacturer to optimise design of a PV/T unit. The PV/T units' energy yield is a function of the position (e.g. different building orientations, different shadow conditions over the day) and operating conditions (e.g. temperature level, consumer energy requirement and daily profile of energy consumption). The developed user-friendly tools may be used for simulation of PV/T units' energy contribution under variety of construction and operating conditions. The simulation program has been used to simulate the performance of PV/Air-heating wall as a promising application of hybrid, PV/T systems. A multi-parameter analysis has been carried out using two reference constructions of the PV/T-Wall under Danish climatic conditions. The first reference assumes PV/T unit with a small light transparency (app. 20%) within the solar spectrum and the second reference assumes a light transparency of 80%. After determination of an optimum airflow rate for both systems, another study was performed in order to determine the set of design parameters, which will lead to the best annual energy yield.
