Optimization calculation method for cold source configuration of central air conditioning systems under different load characteristics

This paper uses the coefficient of variation of hourly cooling load data as the load characteristic index, compares the operating energy consumption of different cold source configuration schemes under four typical climatic conditions, and derives the law of cold source configuration of central air conditioning systems under different climatic conditions (different load characteristics). An optimization mathematical model for the cold source configuration with the hourly cold load variation coefficient and the single unit capacity proportion of small units as variables is established.
