中德生态园被动房技术体验中心暖通空调设计

HVAC design for passive house technology experience center in Sino-German Ecopark

介绍了该工程的概况和暖通空调系统设计,包括设计参数、冷热负荷、冷热源、空调水路系统、空调通风系统、防排烟系统及自动控制系统等。根据热回收式新风机组和末端无动力冷梁对冷水温度高低需求的不同,分设地源热泵机组作为冷热源;采用全热两级热回收式新风机组为室内提供新风。结合工程特点,不同高度空间建筑采用不同的送风形式,大报告厅采用旋流风口,入口大厅采用喷口。对整个建筑的气流组织进行了优化设计,总结了设计中的经验和体会。

Presents the general situation of the project and its heating ventilation and air conditioning system design, including the design parameters, cooling and heating loads, cold and heat sources, air conditioning water system, air conditioning and ventilation system, smoke control and extraction systems and automatic control system. Depending on the different temperature requirements of chilled water for outdoor air handling unit and chilled beam, selects different ground-source heat pump units. Adopts a two- stage total heat recovery outdoor air handling unit to supply outdoor air. In view of architecture characteristics of the buildings, selects various air distribution modes for spaces according to their heights, swirl diffusers in the lecture hall and jet nozzles in the entrance hall. Optimizes the air flow distribution of the whole building, and summaries some experiences and lessons for the design.
