Applicability of combined cooling heating and power (CCHP) technology based on actual energy demand of public buildings

Based on the cascade utilization of energy, CCHP technology can increase the comprehensive energy utilization rate from 40% to 70%-90%. However, the operation effects of building CCHP systems in the domestic pilot projects are generally unsatisfied or even shutdown. Collects the annual hourly energy consumption data of the different types of public buildings in different climate zones, analyses the actual energy demand characteristics of public buildings, simulates the operation effect of building CCHP technology applied to public buildings, and discusses the technology applicability to different public buildings from the aspect of energy efficiency.
