摘要： A system and method of monitoring the performance of a heating, ventilation, or air conditioning (HVAC) system including a controller in communication with a HVAC unit where the method includes monitoring environmental conditions using a controller. Environmental conditions, such as indoor air temperature, indoor humidity and outdoor temperature are measured and used to compute performance parameters that help diagnose HVAC performance problems. The rate of change of indoor air temperature (IATR) and rate of change of indoor humidity (IDHR) are computed and used to determine the sensible heat ratio of the cooling system. The sensible heat ratio, which may or may not be adjusted for transient startup, is used in concert with product performance data, indoor air temperature, indoor humidity, and outdoor air temperature to determine cooling system airflow.
