The Energyconsumption Simulation Of Architecture And Study On The Aquifer Characteristic For The Groundwater Heat Pump System Application

Nowadays, problems of energy and environment are increasingly serious. The study and application of Green Architecture technology with the topic of energy-saving and environmental protection, have been widely spread in the field of architecture. The architecture energy consumption is mostly from heating and air-conditioning, so the energy-saving design of envelop structure and air-conditioning system is the first step for the architecture energy-saving realization. As a kind of Green Architecture technology, groundwater heat pump systems (GWHP) have been widely applied home and abroad, for its virtues of stable performance, high-efficiency and energy-saving.The accurate and detailed data of dynamic load simulation and energy consumption analysis can be used for quantify evaluation of different energy-saving measures used in different areas and architectures; the data is also the selection judgement of well design and heat pump capacity. Therefor, some organizations require that the dynamic load simulation should be used to calculate architecture annual energy consumption , for the purposes of evaluating the architecture energy consumption.The energy consumption of an examples building with different outer wall heat preservation capacity , different outer windows and different ventilation schemes was simulated in this paper. The influence of different factor on heating and air-conditioning energy consumption was analyzed. A suitable energy-saving case data was selected for the next section of this paper. Based on the selected data , the flow-heat transfer in different aquifer was studied by numerical simulation. The distribution characteristics of temperature field and pressure field were analysed. The influences of different geological conditions, wells group location, temperature difference of supply-return groundwater on temperature field and pressure field were compared; some methods for heat transfixion avoiding were put forward . The most difference of GWHP from other heat pump system is the heat/cold source-groundwater. The groundwater system is a key of GWHP system. Based on a practical example, the use of groundwater and production and injection was summarized .
