Air handler unit (AHU) is considered as the main part of the HVAC system consuming nearly half of the total energy. Airflow blockage and leakage has become a significant problem in AHU recently. This paper describes an electrical measurement based study and mainly focuses on the airflow blockage fault detection and the estimation of insufficient airflow. It proposes a relatively simple airflow fault-detection...
ITU has standardized a computational model as Recommendation G.1070 for Quality of Experience (QoE) planning [1]. In our previous work, we proposed a system for calculating the G.1070 visual quality estimate in a monitoring scenario [2]. In G.1070, the visual quality is based, in part, on frame rate, bitrate, and packet-loss rate. For a fixed frame rate and a fixed packet-loss rate, the G.1070 visual...
