An hourly dynamic simulation tool for thermal storage air-conditioning systems is developed. Based on the annual hourly cooling and heating load, operation strategy, presupposed system configuration and other conditions of the project, the simulation tool can automatically simulate the annual hourly operation status of air conditioning systems, quantitative evaluation of operation performance and system benefits of thermal storage air-conditioning systems are extended from previous typical cycles such as summer and winter design days to 365 real cycles throughout the year, the hourly distribution law of cooling and heating load is optimized from previous special cycle to annual hourly dynamic cooling and heating load, and the calculation method is more reasonable and objective. Taking a practical engineering design as an example, the optimization analysis of capacity configuration of thermal storage air-conditioning systems is carried out.
