Thermal Environment Simulation of Buildings on the Ground in Low Enthalpy Geothermal Engineering

Abstract:

By using a variety of energy-saving technologies, low-grade geothermal energy will be efficiently used for improving the indoor thermal environment with few high-grade electric energy in low enthalpy geothermal engineering. In order to be more targeted and precise, geothermal energy conservation engineering should be designed and controlled on the basis of characteristics and variation of indoor thermal environment. Taking the low enthalpy geothermal engineering in the Air Force Command Academy veteran cadre living area as an example, it generalizes the building and simulates the indoor thermal environment by DeST software. The results show that the thermal enironment of rooms which are on the different storeies and different orientations is different. it is be obvious regularity, the thermal enironment of rooms in the high storey and low storey is worse than the middle storey in winter, the thermal enironment of rooms in north is worse than in south, the thermal enironment of rooms in west is worse than in east, and the thermal enironment of rooms in the corner is worse than in the middle. All of these may be a guide to equipment selection, layout of pipe network and terminal equipment, and can provide a theoretical basis for energy conservation design and operations control.
