某超大型地下空間工程空氣能綜合應用
Comprehensive application of air energy in underground space of a super large project
摘要：
西安某地下工程總建筑面積超過70萬m2，地下平均深度超過10 m，為充分利用地下空間空氣能，將地下2層的通風有組織地排至空氣源熱泵室外機側及冷卻塔進風側；空調新風通過敷設在地下的水平土建風道夏季預冷、冬季預熱。建立了模型，計算分析地下空間空氣能利用的節能潛力。工程運行實測數據與分析結果較為吻合。
Abstract：
An underground space project with a total floor area of more than 0.7 million square meters in Xi’an has an average underground depth of more than 10 meters. In order to make full use of the air energy in the underground space, the ventilation of the underground space is systematically discharged to the outdoor unit side of the air-source heat pump and the air inlet side of the cooling tower. The outdoor air of the air conditioning unit is precooled in summer and preheated in winter through the horizontal civil duct laid underground. Through the establishment and calculation of a theoretical model, analyses energy-saving and economic potential of air energy utilization in underground space. The measured data after the project operation are in good agreement with the analysis results.
