Semi-Conductor Plant

Project Overview:  

A multinational semiconductor factory in Shenzhen, China, specialises primarily in the production of automotive PC board-specific products. The key performance of production environment is to be maintained at a constant temperature and humidity. The annual energy consumption of the chiller plant room is approximately 3.7MKH. 

Building Automation System: 

The site is digital ready which has a Mitsubishi PLC control system together with Energy meters. 

Solution:  

Installed a NDE (Network Data Engine) - AI gateway on site and connected to the Mitsubishi PLC system. Installed additional NDE interfacing with Chiller Control Panel. 

Achievement: 

Energy Saving achievement is based on the M&V (Measurement & Verification) from comparison of 2 adjacent days, the energy saving achievement has been verified. The actual savings rate ranges from 13% to 18%, with an average savings rate of approximately 15%.
