Building envelope integrated solar thermal

项目摘要

Vacuum flat plate solar thermal systems offer advantages over both vacuum tube systems by collecting a greater fraction of the available solar resource and flat plate systems by allowing higher temperatures to be achieved with better efficiency. The vacuum envelope if at a pressure of less than 0.1Pa effectively suppresses gaseous conduction and convection allowing thin panels to be developed with increased suitability for building envelope integration.Solar energy availability and thus solar thermal heat generation is often out of phase with heat demand for water or space heating, requiring effective thermal storage to allow demands to be met. In this project designs for durable vacuum flat plate systems will be developed and prototype laboratory scale systems produced for performance evaluation. A detailed model of vacuum plate solar systems linked to different types of thermal storage will be developed. This model will allow different options and approaches for thermal storage, sensible, latent and thermochemical to be simulated to assess the level of solar savings fractions that can be achieved for a range of representative hot water and space heating loads. Prototype stores will be developed and characterised in the lab before outdoor testing of an integrated system comprising vacuum flat plate collector and thermal store.

真空平板太阳能热系统通过收集更大部分的可用太阳能资源而提供优于真空管系统的优点，并且通过允许以更好的效率实现更高的温度而提供优于平板系统的优点。如果真空外壳的压力小于0.1Pa，则可有效抑制气体传导和对流，从而开发出更适合于建筑外壳集成的薄面板。太阳能的可用性以及太阳能热发电通常与水或空间加热的热量需求不同步，需要有效的热存储来满足需求。在该项目中，将开发耐用真空平板系统的设计，并生产实验室规模的原型系统用于性能评估。将开发一个与不同类型的热储存相联系的真空板太阳能系统的详细模型。该模型将允许不同的选项和方法的热存储，显热，潜热和热化学模拟，以评估太阳能节能分数的水平，可以实现一系列代表性的热水和空间加热负荷。在对真空平板集热器和蓄热器组成的集成系统进行室外测试之前，将在实验室中开发和表征原型蓄热器。
