Thermal characteristics of a glazed transpired solar collector with perforating corrugated plate in cold regions

Abstract

Solar heating applied to rural buildings is without a doubt an interesting alternative for reducing energy consumption in cold regions. The thermal performance of transpired solar collector is enhanced by the impingement of jet. To make a better use of the jet impingement, a GTC (glazed transpired solar collector) with perforating corrugated plate is developed. A mathematical model based on the energy balance equations is built to predict the thermal performance of the collector. The simulated results are validated by experiments and they show good agreement with each other. The effects of various key parameters, such as inlet and ambient temperature, total volume flow of air, radiation intensity, height and width of the collector and porosity of the absorber plate, on the thermal performance of the GTC are studied. The thermal performance and economic characteristics of the collector are compared with other transpired solar collectors. The results indicate that the GTC with perforating corrugated plate is applicative enough for its advantages in economy and thermal performance in rural areas of cold regions.
