Air conditioning system design for Dongying Meeting and Exhibition Center
摘要：
展览中心为屋面膜结构的高大空间，夏季因上部空间冷负荷很大，采用分层空调系统，人员活动区域采用全空气低风速空调系统，两侧喷口送风，下侧回风，上部空间设置机械通风系统。会议中心的大空间采用双风机全空气低风速空调系统，办公区采用风机盘管加新风系统。水系统采用两管制、一次泵变流量系统。冷热源采用地源热泵加冰蓄冷系统。
Abstract：
The exhibition center is a large space building with the roof of membrane structure. For the large cooling load in the upper part in summer, the stratificated air conditioning system is adopted. The occupant zone is served by an all-air low-velocity system and air is supplied by nozzle outlets in two opposite side walls and returned from the downside. A mechanical ventilation system is designed in the upper space. The large space in the meeting center is served by a double-fan all-air low-velocity system and the office zone a fan-coil unit plus fresh air system. The water system is of two-pipe with variable flow primary pumps. The cold and heat sources are ground-source heat pump plus ice storage system.
