This invention discloses an energy-saving air conditioning system and its control method for shield tunnels. During periods of low cooling demand in shield tunneling, the system stores cooling capacity through phase change energy storage modules. During periods of high cooling demand, the system releases cooling capacity through these modules. Taking advantage of the intermittent nature of shield tunneling, phase change energy storage achieves peak shaving and valley filling of cooling demand. This reduces the installed capacity of chiller units, lowers investment costs, and slows down frequent start-ups and shutdowns, extending unit lifespan. Furthermore, the chilled water flow rate of the phase change energy storage modules is easily adjustable, enabling precise control of the target temperature. Moreover, the chiller units employ a three-stage condensation method to provide chilled water, with multi-stage condensate recovery and reuse, fully recovering the sensible and latent heat contained in the condensate. This is well-suited to the high-humidity environment inside shield tunnels, significantly improving cooling efficiency and resulting in significant overall energy savings.
