Mitsubishi Heavy Industries Thermal Systems, Ltd. (MHI Thermal Systems) has launched a new model of its "Ene-Conductor" Heat Source Control System for integrated control of centrifugal chillers and peripheral equipment such as chilled water pumps, cooling water pumps, and cooling towers.
The new EC-8 model, to be added to the lineup next month, allows for control of up to eight centrifugal chiller units.
With these features, the new model can be more widely used and installed in overseas large-scale facilities, as well as enhancing the energy conservation for the whole facilities.
Ene-Conductor incorporates the operational and control knowledges and experiences as a centrifugal chiller manufacturer, offering a packaged solution with higher energy-saving control functions, such as controlling the number of centrifugal chillers, controlling the variable flow rate of chilled water and cooling water.
With these packaged features, the new model automatically determines the optimal operation of the entire air conditioning system, reducing power consumption by up to 26 per cent.
addition, because the repeated system design in each project and workload for installation can be reduced, the system can be installed easily. Furthermore, Ene-Conductor can be added to existing facilities, therefore, even without renewing and updating facilities, it is possible to install the Ene-Conductor and realize further energy savings.
The EC-8 model supports both the individual pump system and the multiple pump system widely used in Southeast Asia and the Middle East.
For the communication protocol for exchanging information between machines and sensors, the BACnet protocol has been added in addition to Modbus. This makes it possible to real-time data exchange with a higher-level supervisory control device, improving responsiveness.
In addition, there is less wirings (signal cables), therefore, construction management is also easier. These additional features allow the system to be installed in a broader range of facilities.
