Abstract

The theory of a glazed transpired collector solar air heater in natural convection mode has been developed. This was aimed at generating a framework for the experimental study of the performance of the collector. The theory involved the definition of some of the collector's main geometries, the formulation of the energy balance on the collector and the driving forces within the collector. Dimensional analysis was then applied to the formulations to obtain relationships between important dimensionless groups. The theory of the glazed transpired collector in natural convection mode provides a basis for the development of the collector for application in the areas of space heating and crop drying. This type of collector provides a solution to the challenge of space heating and crop drying at locations where electricity is not available and photovoltaic power is not affordable. It could also contribute to energy savings since it requires no electricity to work.

自然对流模式下玻璃蒸发式太阳能集热器的理论
建立了自然对流模式下的玻璃蒸发集热器太阳能空气加热器理论。这是为了产生一个框架的性能收集器的实验研究。该理论涉及到集热器的一些主要几何形状的定义,集热器上的能量平衡的公式和集热器内的驱动力。然后将量纲分析应用于公式中,以获得重要的无量纲群之间的关系。自然对流方式上釉蒸腾集热器的理论研究为该集热器在空间加热和作物干燥等领域的应用提供了理论基础。这种类型的集热器提供了一种解决方案,解决了在电力不可用和光伏发电负担不起的地方空间加热和作物干燥的挑战。它还有助于节约能源,因为它不需要电力来工作。

期刊介绍: The Journal of Solar Energy Engineering - Including Wind Energy and Building Energy Conservation - publishes research papers that contain original work of permanent interest in all areas of solar energy and energy conservation, as well as discussions of policy and regulatory issues that affect renewable energy technologies and their implementation. Papers that do not include original work, but nonetheless present quality analysis or incremental improvements to past work may be published as Technical Briefs. Review papers are accepted but should be discussed with the Editor prior to submission. The Journal also publishes a section called Solar Scenery that features photographs or graphical displays of significant new installations or research facilities.
