2003年9月7,由天津大学机械学院热能工程系完成的《组合型埋地换热器地源热泵与生态能源建筑研究成果》通过了天津市科委组织的专家鉴定。 该项目建立了梅江综合办公楼生态能源示范工程。其冬季供热、夏季制冷空调系统来自于埋地换热器的地源热泵系统,埋地换热器采用桩埋管、垂直竖井埋管与水平埋管相结合 On September 7, 2003, the “Combined Ground Heat Exchanger Ground Source Heat Pump and Ecological Energy Building Research Achievements” completed by the Department of Thermal Energy Engineering of the Tianjin University Mechanical College passed the expert appraisal organized by Tianjin Science and Technology Commission. The project has established the Meijiang Comprehensive Office Building Ecological Energy Demonstration Project. The winter heating and summer cooling and air-conditioning system comes from the ground source heat pump system of the buried heat exchanger, and the buried heat exchanger uses the piled pipe, the vertical shaft buried pipe and the horizontal buried pipe.
