基于天花板辐射控制的房间温度计算模型。房间热网络模型精确地表示了所有墙壁和房间内部辐射交换中的热质量，用于估算拉普拉斯传递函数，随后用于控制研究。首先，描述了一种计算热源和温度变化对工作温度影响的传递函数的有效方法。然后，将控制工作温度的反馈比例控制系统与控制室温的反馈比例控制系统进行比较。数值模拟表明，对于相同的热舒适性，基于工作温度而不是空气温度的天花板辐射供暖控制的响应时间显著较低。 初步实验结果还表明，基于工作温度的热舒适性得到了改善。关键词:辐射供暖、天花板供暖、室温、控制装置、房间、工作温度、计算、比较、热舒适性、空气温度、热流、能源Scitation:研讨会，ASHRAE Trans。1991年，第97卷，第2部分

A numerical model of room temperature control based on the operative temperature is developed for a room with radiant ceiling heating. A room thermal network model that accurately represents thermal mass in all walls and room interior radiation exchanges is employed for estimation of Laplace transfer functions that are subsequently used for control studies. First, an efficient technique for calculating the transfer functions for the effects of heat sources and temperature changes on operative temperature is described. Then, a feedback proportional control system that controls operative temperature is compared with one that controls room air temperature. Numerical simulations indicate that for equal thermal comfort the response time is significantly lower for control of radiant ceiling heating based on the operative temperature as opposed to the air temperature. Preliminary experimental results also indicate improved thermal comfort based on the operative temperature.KEYWORDS: radiant heating, ceiling heating, room temperature, controls, rooms, operative temperature, calculating, comparing, thermal comfort, air temperature, heat flow, energy sources
