| Abstract: | Based on frequency conversion technology,reform is made in the cooling water circulation system of central air conditioning.Firstly the existing high energy consumption problems is analysed on the central air conditioning system,variable frequency energy saving principle is elaborated,then the temperature difference closed-loop control design on the regulation PID is given.Finally the inverter and PLC control circuit is designed.This study provides guidance for the reform of central air conditioning in design or using departments. |
| Keywords: | central air conditioning frequency conversion technology cooling water circulation system reform design |
