Application of energy saving control technology on air-water linkage of ventilation and air conditioning system to Nanning Underground Railway Line 1

Taking the ventilation and air conditioning system of Macun Station of Nanning Underground Railway Line 1 as an example, investigates the energy consumption of air conditioning equipment, introduces and verifies the air-water linkage control model of the ventilation and air conditioning system, and analyses the energy saving effects under different control modes. The results show that the implementation of air-water linkage control in the air conditioning system of underground railway stations can maximize the energy saving potential, which provides a reference for the energy saving design of the ventilation and air conditioning system for underground railway stations.
