COOL ZONE Mitsubishi’s new HVAC controller
Mitsubishi Electric has launched a new control platform to provide more monitoring and reporting, deliver an increased amount of immediately accessible data, and enhance overall functionality to building operators and facilities managers. The new tool also supports the confi guration, monitoring and pre-emptive maintenance of HVAC systems.
M
ELCloud Commercial is an IoT (Internet of Things) platform that collects data and sends signals to heating, ventilation, and air conditioning (HVAC)
equipment and allows these systems to be operated and monitored remotely from mobile devices, anywhere in the world.
The platform has been designed for commercial installations, such as those used in offi ces, hospitals, shops and hotels, where cooling, heating and ventilation are all essential.
Mitsubishi Electric has undergone extensive fi eld trials
of MELCloud Commercial, with corporate customers throughout Europe and the UK, to build a system that has moved it from an onsite diagnostic tool to a cloud-based ecosystem. HVAC systems account for around 25% of the carbon footprint of our built environment with much of this coming from heating, cooling, powering and operating these buildings. Finding ways to understand where and how energy is being used is therefore key to being able to control and reduce carbon emissions. MELCloud Commercial allows building operators to
remotely manage, monitor and control HVAC systems in multiple buildings from one central location. The control and monitor function can show an entire estate or an individual room, delivering dynamic, real-time information on the systems and their performance. In the systems energy management App, MELCloud Commercial enables energy monitoring and reporting from anything from individual units in single rooms, or for an entire building, right up to estate level monitoring. For service and maintenance professionals, the platform can deliver refrigerant fl ow diagrams and graphical representations of equipment performance, system operational data, all live online. Up to 50 Mitsubishi Electric devices including four MODBUS energy Meters are connected to MELCloud Commercial through a single gateway via a 4G SIM card or LAN Ethernet connection, with multiple gateways able to link up centrally to provide a global overview. MELCLoud Commercial is not restricted to working only with Mitsubishi Electric’s HVAC systems. In addition, other non-HVAC systems can also be monitored and controlled. Just like the HVAC equipment, alerts can be sent to the building manager if there is an alarm.

The system can also record the energy consumption of
the third-party equipment and report it to building users, so equipment such as fridges, ovens and lighting can be monitored and reported on. One of the major new initiatives is the inclusion of an advanced energy dashboard, which allows MELCloud Commercial to monitor and compare the energy consumption of multiple buildings, ranking their usage by kW per hour per building size, or by the number of temperature or consumption alerts. At a more granular level, these workspace rankings can
compare energy consumption between building, fl oors, and even rooms. Using this data, MELCloud Commercial can help prevent a single, or multiple systems within a building from exceeding set consumption limits. The MELCloud Commercial platform off ers two powerful, easy-to-use capabilities. Firstly, a Provisioning Wizard tool, which means customers can convert their buildings into smart, energy- optimised ones. Secondly, the customer has the ultimate authority in choosing who gets access to support these smart buildings. This means that a building manager can receive an outdoor unit alert when a fault/error happens at a building and can then provide access to a service engineer, who can use the Service and Maintenance capabilities of the platform to remotely diagnose the time the incident occurred, how long it lasted, and which warning signs explain the root cause. All this can be done, without the initial cost of an onsite investigation.
The platform has been designed for commercial installations, such as those used in offi ces, hospitals, shops and hotels, where cooling,
heating and ventilation are all essential.
