摘　　要：间歇空调启动过程中建筑室内的温度变化会影响室内的热舒适性。空调启动过程中房间室内温度变化不仅与房间围护结构特性等多种因素有关,而且与使用的空调末端形式有关。通过实验的方法对比研究了房间冬夏两季不同空调末端形式启动过程室内的温度变化规律。实验结果表明,空调启动后房间室内温度随时间均呈指数规律变化,当时间足够长时,房间内温度趋于稳定。理论表达式揭示了空调启动过程中室内温度变化规律,并与实验结果吻合较好。当空调末端使用风机盘管时,冬季温变指数B=0.0741,夏季B=0.0301,均高于毛细管辐射空调。在其他外界条件相同的情况下,房间温变指数受空调末端形式影响很大。The indoor air temperature changing during the starting time of intermittent air-condition would affect thermal comfort. And during starting time, the air temperature characteristics are influenced not only by the building envelope features but also by the terminal forms of air-condition. By experiment, this paper comparatively studies the indoor temperature changing rules of different terminal forms in winter and summer. The solutions show that the variation of indoor air temperature with time follows index number laws and becomes stable when time is long enough. The theoretical analysis reveals the law of air temperature variation and coincides well with the experimental results. When using fan coil, temperature variation index B=0.0741 in winter while B=0.0301 in summer, which is larger than using capillary radiation air condition. In the same outside condition, the temperature variation index is highly affected by the terminal form of intermittent air condition.
