Comparing the Effect of Process Fluid for Wet Ground Heat Exchanger

Abstract

Nowadays, a considerable part of the energy need is provided from non-renewable energy sources such as coal, oil and natural gas. Although fossil fuels are formed in long periods, especially these days they are consumed very rapidly. Therefore, the investigations on renewable energy sources, which can be used as an alternative to fossil fuels are increasing with each passing day. Recently, in order to increase heat transfer in the ground heat exchanger, the applications of moistening the soil are existing in the literature. In this research study, the effects of process fluid on heat transfer were investigated comparatively in a wet-soil source heat exchanger. The contribution to the thermal efficiency of air and water as a process fluid was examined. In this study, it is aimed to reduce energy costs. It has been determined that it will make a significant contribution to energy saving in energy-efficient smart buildings.
