天津市某绿色建筑暖通设计方案分析

以天津市某绿色建筑的计算负荷为基础,通过分析不同冷热源方案全寿命周期成本,确定采用地源热泵为系统的冷热源。对地源热泵系统地源侧的年吸、释热量进行计算和分析,确保系统长期运行的稳定性。结合建筑部分负荷运行时间和地源热泵机组部分负荷性能参数,对热泵机组的选型进行分析。此外,对水系统的运行策略和室内空气品质的调控性加以分析。

Design Plan of One Green Building in Tianjin

The building load of one green building in Tianjin was taken as the foundation,considering the life cycle cost of different heating and cooling sources,the ground source heat pump(GSHP) was chosen as the heating and cooling source of the system.The heat absorption and release to the side of soil of GSHP was calculated to ensure the stability of the system for long-term operation.The unit selection of GSHP was analyzed combining the operation time of part load of the building and the part load performance parameters of the heat pump unit.In addition,the operation strategy of water system and the regulation and control of indoor air quality were analyzed.
