网安基地展示中心暖通空调系统绿色设计及节能减排分析
Green design and energy saving and carbon emission reduction analysis of HVAC systems in NCC Exhibition Center
摘要：
网安基地展示中心项目以绿色建筑三星级为目标，采用了地埋管地源热泵、毛细管辐射供冷供暖、过渡季新风免费供冷、三维热管排风热回收、变频调速、空气净化、展厅CO2浓度监控、地下车库CO浓度监控、采光顶温度监控及自动通风系统等多项绿色节能技术。结合GB/T 50378—2014《绿色建筑评价标准》的相关要求，介绍了该项目暖通空调绿色设计方案。通过建立参照基准模型，计算分析了暖通空调各系统的节能减排效益。经计算分析可知，该项目年单位面积耗电量降低至26 kW·h/m2，年单位面积碳排放量降低至13.66 kg/m2，体现了高能效、低能耗、低碳排放的效果。
Abstract：
For achieving the three-star green building certification, the NCC Exhibition Center adopts numbers of energy saving and environmental protection technologies such as the ground-source heat pump system with buried pipes, capillary radiant cooling and heating, free cooling with outdoor air during the transition season, three-dimensional heat pipe exhaust heat recovery device, variable frequency control, air purification device, CO2 concentration monitoring system in the exhibition hall, CO concentration monitoring system in the underground garage, automatically controlled ventilation systems with skylight temperature monitoring, etc. This paper presents the HVAC green design scheme of the project in combination with the relevant requirements of GB/T 50378-2014 Green building assessment standard. By setting a baseline model, the energy saving and carbon emission reduction benefits of various parts of the HVAC system are calculated and analysed. The annual electricity consumption index of this project is as low as 26 kWh/m2 and the annual carbon emission is as low as 13.66 kg/m2, which reflects the high energy efficiency, low energy consumption, and low carbon emission.
