Heat Transfer in Windows

This lecture covers the heat transfer mechanisms in windows, including spectral transmittance, reflection, and absorption of incident radiation. It discusses the fraction of radiation reflected, transmitted, and absorbed by single-layer windows, as well as the radiative properties of different materials used in windows. The lecture also explores the concept of radiosity in windows and the impact of coatings on the overall transmittance and reflectance. Additionally, it delves into the design considerations for flat plate solar collectors and enclosures with windows, emphasizing the importance of understanding radiative properties for efficient heat transfer.
