摘要:地源热泵是利用浅层地能进行供热制冷的新型能源利用技术,是热泵的一种。地源热泵通常是指能转移地下土壤中热量或者冷量到所需要的地方。冬季地源把热量从地下土壤中转移到建筑物内,夏季再把地下的冷量转移到建筑物内。
本设计为万象办公楼地源热泵空调、新风及热水项目,其建筑面积10000㎡。方案采用地源热泵空调系统,室内末端采用风机盘管+新风系统,冷热源采用地埋管+冷却塔。设计包含空调负荷计算,空调方案选择,室外地埋管系统,室内水管系统设计,冷却塔水力计算,热平衡计算,以及末端设备选型及计算。完成设计以后,达到舒适、环保、节能、经济要求,根据各种计算结果,通过性价比分析,进行了设备选型,确保设备 容量、压力、噪声等方面满足要求,最后绘制了相关的设计及施工图,完成整个空调系统设计。

Abstract: Ground Source Heat Pump,a kind of heat pump,is a new technology that use shallow geothermal energy for heating and cooling.It is Usually refers to shift heat or cold from the underground soil volume to where needed it.Ground Source Heat Pump also takes advantage of the capabilities that the underground soil can store thermal energy and refrigeration.In the winter,ground-source heat pump transferred to the soil from the ground to a building while it transferred the cold air to it in summer.
This design is The Wanxiang office building in Changzhou, Ground Source Heat Pump and fresh air hot water Air-conditioning System. The building covers an area of 10000 square meters. The system adopts Ground Source Heat Pump air-conditioning system, office building indoor air conditioning. The cold and heat sources adopt buried tube + cooling tower. The designs include air conditioning load calculation, air conditioning program selection, outdoor buried tube system, and indoor plumbing systems design, cooling tower hydraulic calculation, air tubes and hydraulic calculation of water and related end equipment of air-conditioning selection and calculation. The air conditioning and hot water systems designed to achieve comfortable, environmental protection, energy-saving, economic. According to various calculation results through cost-effective analysis, the selection of equipment to ensure that the equipment capacity, pressure, satisfy noise requirements. The last to draw the related design and construction drawings, complete the final design of the entire air-conditioning system.
Key Words: Ground Source Heat Pump Air conditioning system; buried pipe; cooling and heating load; fresh air system.
