part is a layer of insulation-soil or air-soil. Soil temperature fluctuations and heat emissions have been investigated through the soil bottom. The heat emissions in SWHCs and water heating collectors are quite similar.
Abstract
Soil solar water heating collectors (SWHCs) are the subject of consideration; their bottom part is a layer of insulation-soil or air-soil. Soil temperature fluctuations and heat emissions have been investigated through the soil bottom. The heat emissions in SWHCs and water heating collectors are quite similar.
