在过去的十年里，随着人们对地板辐射供暖系统重新产生兴趣，最优控制的问题变得有争议。Friedlander（1986年）和Adelman（1988年）根据室外温度和所需供水温度之间存在直接线性关系的原则，推荐室外重置控制。ASHRAE（1987）还指出，由于恒温器需求和向空间输送热量之间的时间差，供水温度应根据外部温度变化。相比之下，MacCluer（1989）提出了比例流量调制的概念，并声称必须控制输送到楼板的热量速率，而不是温度。 为了评估这些问题，在1990-91年的加热季节，通过实验室环境中的物理实验，对比例通量调制和各种类型的温度调制方法进行了比较研究（Leigh 1991a，1991b）。结果表明，与各种类型的温度调制方法相比，比例磁通调制方法通过在设定点附近保持稳定的室内温度，并通过演示对任何内部负载干扰的即时响应，具有良好的性能。温度调制方法对复位率很敏感。通过流量抑制进行的温度调节显示出对锅炉水温的敏感性。 强烈建议使用室内温度反馈，以帮助补偿这些潜在误差，从而最大限度地减少温度调节对设定点的偏移。关键词:热流、温度控制、供暖、地板供暖、辐射供暖、水温、控制、比较、室温、室外温度、优化。引用:研讨会，ASHRAE Trans。1994年，第100卷，第一部分

With renewed interest in radiant floor-heating systems in the past decade, the issue of optimum control has become controversial. Friedlander (1986) and Adelman (1988) recommend outdoor reset control based on the principle that there is a direct, linear relationship between outside temperature and the required supply water temperature. ASHRAE (1987) also states that the supply water temperature should be varied in accordance with outside temperature due to the time lag between thermostat demand and heat delivery to the space. In contrast, MacCluer (1989) proposed the concept of proportional flux-modulation and claimed that the rate of heat sent to the floor slab must be controlled, not the temperature. To evaluate these issues, a comparative study of proportional flux-modulation and various types of temperature-modulation approaches was conducted through physical experiments in a laboratory setting during the 1990-91 heating season (Leigh 1991a, 1991b). The results show that proportional flux-modulation favourably compares with various types of temperature-modulation approaches by maintaining a stable indoor temperature around the setpoint and by demonstrating immediate response to any internal load disturbance. Temperature-modulation approaches show sensitivity to the reset ratio. Temperature modulation via flow inhibition shows sensitivity to the boiler water temperature. Indoor temperature feedback is highly recommended to help compensate for these potential errors and thus minimise the offset from the setpoint with temperature modulation.KEYWORDS: heat flow, temperature control, heating, floor heating, radiant heating, water temperature, controls, comparing, room temperature, outdoor temperature, optimisation.
