建造了一个实验设施，由两个3 x 4.4 x 3.8米（9.8 x 14.4 x 12.4英尺）的房间组成，房间结构相同。该测试设施旨在同时比较两种不同的控制策略，每种策略都在单独的房间中实施。每个房间都安装了一台燃气锅炉，为地板辐射供暖系统提供热水。回路中还安装了一个电热储水箱，以便直接从储水箱向楼板供应热水。后一种安排有助于准确评估不同流量调节控制策略的性能。评估了四种不同的控制策略。1） 基于开关控制的传统空气温度。泵在开关模式下运行，以将室内空气温度保持在选定的限制范围内。 2） 数字PI控制。PI控制器用于调节双向阀，以将室温保持在设定点。3） 基于开关控制的楼板温度。泵在开关模式下运行，以将板坯温度保持在高限和低限范围内。4） 双参数（空气和楼板温度）开关控制。泵在开关模式下运行，以将室内空气和板坯温度保持在所需范围内。来自房间和板坯温度的反馈信号以交替顺序用于控制泵。结果表明，双参数开关控制使室温和板坯温度保持在合理范围内，并具有良好的温度调节性能。由于其结构简单、成本低廉，是辐射热控制的理想选择。关键词:1997年，温度控制，辐射供暖，地板供暖，实验，测试，比较，室温，板坯，燃气锅炉，热水供应，精度，性能，控制: 研讨会，ASHRAE Trans。1997年，第103卷，第一部分

An experimental facility consisting of two 3 x 4.4 x 3.8m (9.8 x 14.4 x 12.4 ft) rooms identical in construction was built. The test facility was designed to enable simultaneous comparison of two different control strategies, each implemented in a separate room. Each room was installed with a gas-fired boiler supplying hot water to the radiant floor heating system. An electrically heated storage tank was also installed in the circuit so that hot water to the floor slab could be supplied directly from the storage tank. This latter arrangement was found to be useful in accurately assessing the performance of different flow-modulating control strategies. Four different control strategies were evaluated. 1) Conventional air temperature-based on-off control. The pump is operated in on-off mode to maintain room air temperature within chosen limits. 2) Digital PI control. A PI controller is used to modulate the two-way valve to maintain room air temperature at the setpoint. 3) Floor slab temperature-based on-off control. The pump is operated in the on-off mode to maintain the slab temperature within high and low limits. 4) Two-parameter (air and floor slab temperature) on-off control. The pump is operated in the on-off mode to maintain both room air and slab temperatures within desired limits. Feedback signals from the room and slab temperatures were used in alternate sequence to control the pump. Results show that two-parameter on-off control keeps the room air temperature and slab temperature within reasonable limits and gives good temperature regulation. Being simple and cost-effective, it is a good candidate for radiant heat control.KEYWORDS: year 1997, Temperature control, radiant heating, floor heating, experiment, testing, comparing, room temperature, slabs, gas fired boilers, hot water supply, accuracy, performance, controls
