The Analysis of the Variable Frequency Energy Saving Renovation Case which is Used in the Central Air Conditiong System of the ShenZhen Metro Station

In the phase of the Shenzhen metro project, all the fans and pumps, which is being used in the central air conditioning system, are used fixed frequency operation mode. and there is a greater possible to save energy when it is in the offpeak time and non- service time, especially to the public area air conditioning system （we call it the large system） and the water system. By introducing the variable frequency energy saving renovation case which is used in the central air conditiong system of the ShenZhen metro OCT station, this stydy explains the applications of the variable frequency technology in the metro central air conditioning system, discusses how to consummate the renovation while analyzing the problems, and shows the economy and feasibility of this renovation.
