It is difficult to investigate the performance of airconditioning systems with thermal energy storage tanks because flow rate in the system is unmeasured in almost all systems. The aim of this research is to estimate the flow rate of such air-conditioning systems using temperature data in tanks which is easy to measure. In this paper, the effects of heat gain through the tank wall, the time interval of data and the number of temperature measuring points in tank on the accuracy of flow rate estimation are studied using generated temperature data by simulation.
