Study on the heat gain through a twin glass window (TGW) using an organic PCM

Abstract

The glazed windowing systems are the essential components for a wide range of structures, and their heat transfer performance does have a substantial impact on increasing an human comfort as well as lowering electricity usage. The current study analyzes the heat transfer characteristics of a twin glass window (TGW) unit, under the influence of a commercially procured organic phase changing medium (PCM). The results have been compared the performance of the normal TGW without the presence of PCM and the inferences are discussed. The two TGW units had been erected in an prototype room space facing south direction in a South Indian region. Through a lengthy experimental investigation, the room space temperatures, glazing surface temperatures, transmittance of the glazing surface and the heat exchange rate across the TGW unit of both the normal TGW unit as well as PCM amalgamated TGW units were assessed. The testing findings demonstrated that amalgamating PCM is being a potential solution reduce the indoor temperature having TGW unit, without sacrifice of entering sun light inside the room space. By this way, it would help to reduce the cooling load of the air-conditioning system, which results in the reduction of total eenrgy consumption of the building space.
