讨论了两栋建筑的现场数据，这些数据表明，持续运行的、由风机驱动的混合箱的风机能耗可以抵消因中央风机缩小而产生的节能。介绍了建筑物的风机能量数据，并对其进行了讨论，同时还对替代的空气分配方案进行了模拟。还介绍了基于铭牌额定值和理论计算的相对风扇功率估计。讨论在冷空气分配系统中最小化风扇能量的选项。 关键词:建筑、空调、低温、空气、风机、能耗、风道末端、模型、计算、配风。引文:研讨会，ASHRAE交易1993，第99卷，pt。1.

Discusses field data from two buildings with cold air distribution which indicate that the fan energy consumption of continuously-operating, fan-powered mixing boxes can offset the energy savings resulting from downsized central fans. Presents the fan energy data from buildings and discusses them, along with simulations of alternative air distribution options. Also presents estimates of relative fan power based on nameplate ratings and theoretical calculations. Discusses options for minimising fan energy in cold air distribution systems.KEYWORDS: Buildings, air conditioning, low temperature, air, fans, energy consumption, air terminals, models, calculating, air distribution.
