摘　　要：暖通空调系统的高效节能运行高度依赖于传感器测量的准确性。在传感器全寿命运行周期中,不可避免发生各种故障,影响其准确性。为探究传感器故障对不同暖通空调系统的影响,文章以室温传感器偏差故障为例,针对武汉地区某办公建筑,同时开展地源热泵和"冷水机组+锅炉"两种暖通空调系统形式的能耗建模,对比分析-5℃~+5℃偏差故障对两种系统运行能耗、工作性能及室内热舒适性的影响差异。结果表明:室温传感器故障的偏差幅值方向对两种系统运行能耗、工作性能及室内热舒适性的影响规律不同。其中,地源热泵系统能耗受室温传感器偏差故障影响相对更小。The high-efficiency and energy-saving operation of heating,ventilation and air-conditioning(HVAC)systems rely highly on the accuracy of sensor measurements.Various sensor faults which are inevitable throughout the HVAC system life cycle causes adverse effects on the measurements accuracy.To explore the impacts of the sensor faults on different HVAC systems,this study takes the indoor air temperature sensor bias fault as an example.For an office building in Wuhan,this study compares two different systems,i.e.,the ground source heat pump(GSHP)system and the chillers+boiler(CB)system.Bias faults are added to the indoor air temperature sensor of the two different systems.The added temperature bias amplitude ranges from-5 to 5℃which includes both positive and negative bias fault directions.The sensor fault impacts are quantitatively analyzed in terms of three system operating performance metrics like the system energy consumption,the working performance and the indoor thermal comfort.For the two HVAC systems,results show that the bias amplitude and direction of indoor air temperature sensor faults have different impacts on the three system operating performance metrics.Specifically,the energy consumption of GSHP system is less affected by the bias fault of indoor air temperature sensor.
