引言 虽然平板型集热器到现在已经使用了三十多年,但对它各运行部分工作特性的深入细致地研究只是在近期才开展的。大体上所有的集热器都是由几个基本的部分组成: (1)吸热板 短波太阳辐射照射在吸热板上被吸收转变成热能。 (2)绝热箱 消除或者大量减少收集系统的热损。 (3)盖板
INTRODUCTION Although flat-panel collectors have been in use for more than three decades now, in-depth and detailed studies of the operational characteristics of each of them have only recently been undertaken. In principle, all collectors are made up of several basic components: (1) Short-wave solar radiation of the heat-absorbing plate is absorbed and converted into heat energy on the heat-absorbing plate. (2) The heat box eliminates or substantially reduces the heat loss of the collection system. (3) cover
