摘　　要：经调研,多数办公类项目均采用传统的热湿耦合降温除湿方式处理室内负荷,该方式需冷源常年提供7℃左右冷冻水,主机能效相对较低且室内空调末端处理空气过程中产生的凝结水易滋生细菌,从节能低碳及健康角度考虑均有必要研究更好的技术方案。对比了采用传统空调与干式风盘、主动式冷梁、冷辐射吊顶及全空气变风量复合干式风盘系统的热湿处理过程及优缺点,结合某办公项目实例进行了具体的温湿度独立处理方案分析计算,系统能效可达到约6.2,优化冷源方案利用高温冷机负担室内负荷并预冷新风,其承担负荷比例高达73.5%。A survey of existing projects showed that most office projects adopt the traditional cooling and dehumidification method of heat and humidity coupling to handle indoor cooling loads,which requires a cold source to provide chilled water at about 7℃all year round.Theenergy efficiency of thehost isrelatively lowand condensate water is easy to breed bacteria in the process of air treatment at the terminal units of the air-conditioning system.Therefore,from the perspective of energy saving,carbon reduction and health,it is necessary to find a better technical solution.This paper compared the heat and humidity treatment processes of different systems and their respective advantages and disadvantages,including the use of traditional air conditioning with dry fan coil unit system,the active cold beam system,the cold radiation ceiling system and all-air variable air volume composite dry fan coil system.In combination with the case of an office project,this paper analyzed and calculated the specific independent temperature and humidity control scheme.The energy efficiency of the system can reach approximately 6.2.The optimized cold source scheme utilizes a high temperature chiller to bear indoor loads and precool fresh air,with a load bearing ratio of up to 73.5%.
