Ground Source Heat Pump Air-Conditioning System Design in a Public Building in Xi'an

地源热泵系统因其节约常规能源、充分利用可再生能源以及减少环境污染和资源破坏等优点,在实际工程中逐渐得到广泛的应用。本文针对西安某工程项目采用的地源热泵复合式系统的设计过程进行了介绍,重点对地下换热器的设计进行了详细地说明,并从经济性和环境效益方面对地源热泵复合系统和常规的蒸汽溴化锂机组+城市供热系统进行了比较,分析了地源热泵复合系统的节能和环保方面的优势。

Ground source heat pump system is widely applied in practice for its conventional energy saving, making full use of renewable energy, reducing environmental pollution and destruction of resources. An actual project in Xi＇an which adopted ground source heat pump system is introduced in this paper. The design method of the borehole heat-exchangers is introduced in detail. It is found that the complex ground-source heat pump system has the advantage of energy-saving and environment protection from the comparison of the economic and environmental benefits analysis between the ground-source heat pump combined system and conventional steam generating units LiBr ＋ urban heating system.
