초록

A cooling system at a building operates to maintain indoor temperature and humidity to meet a certain thermal comfort level for occupants. The temperature sensor for the supply chilled water is a vital component for the proper operation of the cooling system. A malfunctioning temperature sensor, leading to discrepancies between actual and measured temperature values, can result in degraded cooling system performance and an increase in cooling energy consumption. If the sensor fault is continued, in addition, indoor thermal environment cannot be properly maintained. Therefore, there is a need to evaluate influences of the faulty sensor during operation of the cooling system. This study conducted energy and thermal analysis using the EnergyPlus simulation program by varying sensor fault offsets which represents a faulty sensor. Based on the simulation results, this study concluded that negative offsets adversely affected indoor thermal comfort, while positive offsets increased cooling energy consumption.
