While occupancy-based control and other demand management control strategies have demonstrated potential, little is known about how these changes in heating, ventilation, and air-conditioning (HVAC) control impacts occupants’ perception of the thermal conditions in their home. In this paper, occupants’ thermal comfort perceptions and use of thermostat overrides under three different control strategies (programmable thermostat operation, occupancy-reactive control, and pre-cooling/pre-heating for load shifting) are analyzed. Thermal comfort data were collected through six occupant surveys administered to 54 participants in the summer and winter months in two high-rise condominium buildings in Toronto, Canada. Minor changes to reported thermal sensation scores were observed in both the occupancy-based and load shifting control scenarios, however, overall reported thermal sensation scores remained neutral. Occupants’ use of overrides did not change significantly during occupancy-based control periods, however, during load shifting control, occupants frequently overrode strategy temperature setpoints – which indicates that many participants likely experienced thermal discomfort beyond their tolerance level. Occupants’ use of strategy overrides during load shifting control strategy operation in the cooling season significantly reduced strategy efficacy. Reducing the maximum temperature setback during load shifting control to 3 °C during the cooling season was recommended to reduce occupant override and improve realized peak-period load reductions.

当代高层公寓不同温控策略下热工况感知

虽然基于占用的控制和其他需求管理控制策略已显示出潜力,但人们对供暖、通风和空调 (HVAC) 控制的这些变化如何影响住户对其家中热条件的感知知之甚少。在本文中,分析了三种不同控制策略(可编程恒温器操作、占用反应控制和用于负载转移的预冷/预热)下居住者的热舒适感知和恒温器超控的使用。热舒适数据是通过在加拿大多伦多的两座高层公寓建筑中在夏季和冬季对 54 名参与者进行的六次居住者调查收集的。然而,在基于占用和负载转移控制场景中都观察到报告的热感觉分数的微小变化,总体报告的热感觉评分保持中性。在基于占用的控制期间,占用者对超控的使用没有显着变化,但是,在负载转移控制期间,占用者经常超越策略温度设定值——这表明许多参与者可能经历了超出其耐受水平的热不适。乘员在降温季节负荷转移控制策略运行期间使用策略覆盖显着降低了策略效力。建议在冷却季节将负荷转移控制期间的最高温度下降降低到 3°C,以减少乘员超控并改善实现的高峰期负荷减少。在基于占用的控制期间,占用者对超控的使用没有显着变化,但是,在负载转移控制期间,占用者经常超越策略温度设定值——这表明许多参与者可能经历了超出其耐受水平的热不适。乘员在降温季节负荷转移控制策略运行期间使用策略覆盖显着降低了策略效力。建议在冷却季节将负荷转移控制期间的最高温度下降降低到 3°C,以减少乘员超控并改善实现的高峰期负荷减少。在基于占用的控制期间,占用者对超控的使用没有显着变化,但是,在负载转移控制期间,占用者经常超越策略温度设定值——这表明许多参与者可能经历了超出其耐受水平的热不适。乘员在降温季节负荷转移控制策略运行期间使用策略覆盖显着降低了策略效力。建议在冷却季节将负荷转移控制期间的最高温度下降降低到 3°C,以减少乘员超控并改善实现的高峰期负荷减少。居住者经常超越策略温度设定值——这表明许多参与者可能经历了超出其耐受水平的热不适。乘员在降温季节负荷转移控制策略运行期间使用策略覆盖显着降低了策略效力。建议在冷却季节将负荷转移控制期间的最高温度下降降低到 3°C,以减少乘员超控并改善实现的高峰期负荷减少。居住者经常超越策略温度设定值——这表明许多参与者可能经历了超出其耐受水平的热不适。乘员在降温季节负荷转移控制策略运行期间使用策略覆盖显着降低了策略效力。建议在冷却季节将负荷转移控制期间的最高温度下降降低到 3°C,以减少乘员超控并改善实现的高峰期负荷减少。
