随着矿物燃料的日益消耗和能源需求量的俱增,人们力求从非常规能源中寻求能源。就低温热利用来说,太阳能已挤进可利用能源的行列。以水或空气作为传热工质的平板集热器是利用太阳能的重要装置之一。平板太阳能集热器可用于家庭或建筑物的热水供应和采暖空调。这些集热器的性能预测对于系统设计来说至关重要,而且其性能取决于许多参数。为了预测太阳能平板集热器的性能,本文列出了三个诺谟图。
With the increasing consumption of fossil fuels and the increasing demand for energy, people are seeking energy from unconventional sources. For low temperature heat use, solar power has squeezed into the ranks of available energy sources. Flat water collectors using water or air as a heat transfer medium are one of the important devices that utilize solar energy. Flat-panel solar collectors can be used for hot water supply and heating and air conditioning in homes or buildings. The performance prediction of these collectors is crucial to the system design and its performance depends on many parameters. In order to predict the performance of solar panel collectors, this article lists three nomograms.
