The Heat Efficiency of Solar Ground Water-Heating Collectors

摘要

A numerical heat model of a ground solar water-heating collector (GSWC) has been developed and its heat losses have been investigated. The heat losses in the GSWC and in "ordinary" Hat collectors are shown to be similar. The model can be used to choose the constructive parameters of the GSWC and to estimate the temperatures in a ground layer under different conditions on the surface (opened and closed surfaces) and at a varying densities of solar radiation and surrounding temperatures.
