Researching on Energy - saving of Metro's Air - conditioning System

At present, the energy consumption of air conditioning system is about 30% of the total energy consumption in the whole metro system in our country.The metro air conditioning system in our country is generally designed according to the peak load at a specified future date from 25 to 30 years. While the load of metro air conditioning system fluctuates greatly each day and each year, there is great potential for energy saving in the metro air conditioning system. It is very important how to adjust the function of air conditioning system according to the actual load and to save energy in the furthest way.
