本综述通过两种根本不同的方法（即光谱选择性和光热效应）处理了节能窗户开发中的关键问题。因此，本次审查分为两部分。第一部分回顾了基于理想窗户概念的工程考虑因素，包括光谱选择性、玻璃规模、季节因素和相关热传递。特别是，引入了具有优化工程参数和物理特性的光谱选择性窗口设计和金属基薄膜。第二部分介绍了一种通过纳米结构薄膜和涂层的光热效应实现隔热的新方法。限制通过窗户的热流的关键是隔热，传统上隔热是由带有隔热层的多层玻璃结构构成的。最近提出了一种不依赖于任何绝缘介质，而是依赖于纳米材料涂层的光热效应的新概念并进行了实验验证。光谱选择性和光热效应这两个概念都是针对节能窗户应用而引入的。通过薄膜和涂层的各种纳米结构的光热效应，提出了开发节能窗户的新方向。
This review deals with critical issues in the development of energy-efficient windows from two fundamentally different approaches, namely, spectral selectivity and photothermal effect. This review is therefore divided into two parts. The first part reviews the engineering considerations based on an ideal window concept in terms of spectral selectivity, glazing scale, seasonal factors, and related thermal transfer. In particular, spectrally selective window designs and metal-based thin films are introduced with optimized engineering parameters and physical properties. The second part introduces a new approach of thermal insulation via the photothermal effect of the nanostructured thin films and coatings. The key that limits the heat flow through windows is the thermal insulation, which is traditionally constructed by multi-pane structures with an insulating layer. A novel concept not relying on any insulating media, but photothermal effects of nanomaterial coatings has been recently proposed and experimental verified. Both concepts of spectral selectivity and photothermal effects are introduced for energy-efficient window applications. A new direction is proposed in the development of the energy-efficient windows via the photothermal effects in various nanostructures of thin films and coatings.
