Modelling and Experimental Verification of an Unglazed Metal Façade Collector Model

Original language description

The paper presents a theoretical model for energy performance simulation of an unglazed metal façade collector (UMFC). Different configurations of UMFC were developed and experimentally tested with the use of an indoor solar simulator to perform a verification process. The verification of the model demonstrated that there is a good agreement between the simulated and experimentally obtained results. The sensitivity analysis has been performed to demonstrate the influence of the wind-forced convection model on the theoretically calculated efficiency. However, the results of the analysis indicated that it is extremely important to identify an appropriate wind-forced convection correlation for the estimation of the thermal performance of a UMFC. A large number of correlations for wind-forced convection presented in the literature demonstrated that there is no universally acceptable correlation. The difference was caused by different combinations of experimental and operating conditions (ambient air temperature, wind range, wind tunnel/outdoor/indoor measurement, instrumentation, surroundings, etc.). Therefore, it was highly recommended to provide a long-term verification process of the model since the climatic and operating conditions (especially wind-related conditions for instance wind speed, wind direction, wind turbulence, etc.) are different compared to an indoor verification process.
