Ene-Conductor: Heat Source Control System
The Ene-Conductor from Mitsubishi Heavy Industries Thermal Systems (referred to as “MHI Thermal Systems”) is a chiller control system for controlling centrifugal chillers, associated cold water pumps and cooling towers. The Ene-Conductor packs the unparalleled expertise in chiller control, as a chiller manufacturer MHI Thermal Systems, into a single package, allowing superior control of chiller equipment. By exercising optimal control over the system as a whole, the Ene-Conductor maximizes chiller performance, delivering overall electricity savings of around 65% compared to existing centrifugal chiller systems, and otherwise contributes to significant reductions in CO2 emissions in office buildings, commercial premises, and factories.
Modern centrifugal chillers use inverter technology to control compressor speed and otherwise achieve world-class efficiencies, thereby helping chillers to conserve energy. However, in applications that feature multiple chillers or ancillary devices, the optimum mode of operation differs markedly depending on operating conditions, and users find that it can be difficult to maximize performance and optimize the efficiency of the heat source system as a whole.
In the past, operators had no option but to implement bespoke solutions appropriate to their individual system. Now, however, the Ene-Conductor has packed into a single package expertise on holistic system control. Able to automatically determine the optimum operating mode, the Ene-Conductor enables greater energy savings than traditional approaches, and also helps reduce human resource requirements and boost operational efficiency.
1. Optimized Control Maximizes Chiller Performance and System COP
The Ene-Conductor is able to optimize chiller performance by exchanging a large amount of operational data with the chiller unit and running control calculations. Even in systems that include multiple chillers, each with a different optimum loading, the Ene-Conductor automatically calculates the load distribution that maximizes the Coefficient of Performance (COP) of the system as a whole. By continually exercising optimized and efficient control, the Ene-Conductor delivers significant energy savings.
2. A Comprehensive Suite of Energy Saving Features
By combining all the software necessary to control chiller equipment in a single package, the Ene-Conductor makes system design and installation a breeze.
3. Remote Monitoring (Internet Connection) Option
The Ene-Conductor uses a local area network to enable visualization of system status, enabling remote monitoring, thereby improving efficiency and enabling immediate response to problems.
4. Central Monitoring Function and Connection to Master Unit (Optional)
The Ene-Conductor can also be connected to a centrally-monitored programmable logic controller (PLC), enabling the status of all devices connected to the Ene-Conductor to be monitored from a central control room, so that they can be operated automatically while being monitored by an operator, and otherwise boosting efficiency and energy savings while reducing human resource requirements.
5. Superior User Interface
The Ene-Conductor also improves convenience for users by replacing the traditionally complex user interface with a simpler interface. The interface comprises a 10.4 inch touch panel that can be used intuitively by anyone, offering superior operability, thereby facilitating operation.
6. All-in-One Service from Design to Installation
Forget partial solutions. The Ene-Conductor allows you to optimize your entire system! MHI Thermal Systems offers an all-in-one-service that covers everything from fielding your chiller system requirements and precisely understanding your current situation to proposing an optimized solution, designing and installing the system, and offering ongoing support.
Ene-Conductor total chiller control system won the 2013 Minister of Economy, Trade and Industry award for energy conservation.
In a ceremony, the Energy Conservation Center, Japan presented the 2013 Minister of Economy, Trade and Industry award for a product or business model to the Ene-Conductor total cold source control system from Mitsubishi Heavy Industries.
The Last Frontier in Factory Efficiency Proved More Challenging than Expected
Do you know what percentage of the electricity used by your factory is consumed by cooling/heating source systems? The percentage is higher than you would expect (between 20% and 50% according to Mitsubishi Heavy Industries Thermal Systems’ research). And yet, not many clients have implemented, or are considering implementing, steps to improve the efficiency of their cooling/heating source systems.
