Air conditioning energy efficient operation and management based on supply air state for underground projects

Establishes an operation energy consumption model of centralized air conditioning systems based on the characteristics of the underground projects, and gives the strategy in solving. Taking the supply air state in the air conditioned room as a connection point when solving the model, divides the model into two phases—air supply and air handling, and discusses the solving methods for that two phases, which simplifies the calculation and produces the operation scheme with the lowest energy consumption, under the condition of satisfying the environment requirements in the air conditioned room.
