The world of vertical transportation is experiencing a paradigm shift with the introduction of Mitsubishi Electric's NEXIEZ-MRL version 2 elevator. This innovative solution represents a significant leap forward in elevator technology, offering a perfect blend of efficiency, sustainability, and passenger comfort. As urban landscapes continue to evolve and buildings reach new heights, the demand for advanced elevator systems has never been greater. The NEXIEZ-MRL ver. 2 rises to this challenge, providing a cutting-edge solution that caters to the needs of modern architecture while prioritizing energy conservation and user experience.

In this comprehensive exploration of the NEXIEZ-MRL ver. 2, we will delve into its groundbreaking features, examine its impact on building design and functionality, and understand how it is reshaping the future of vertical mobility. From its energy-efficient operations to its space-saving design, every aspect of this system has been meticulously crafted to deliver superior performance and reliability.

Redefining Elevator Technology

The NEXIEZ-MRL ver. 2 system represents a quantum leap in elevator design and functionality. By eliminating the need for a traditional machine room, this innovative solution opens up new possibilities for architects and building designers. The compact nature of the system allows for greater flexibility in building layouts, enabling more efficient use of space and potentially increasing the rentable area of a structure.

Energy efficiency at its core

One of the standout features of the NEXIEZ-MRL ver. 2 is its regenerative drive system. This innovative technology harnesses the energy generated during braking and converts it into usable electricity, which is then fed back into the building's power grid.

By recapturing and reusing energy that would otherwise be lost as heat, this system can reduce the elevator's net energy consumption by up to 35% compared to non-regenerative systems. This not only reduces the overall energy consumption of the elevator system but also contributes to the building's sustainability goals.

Lighting is another area where the NEXIEZ-MRL ver. 2 demonstrates its commitment to energy conservation. The system utilizes LED lighting throughout, from the car interior to the hall fixtures. LEDs not only consume less power than traditional lighting options but also have a longer lifespan, reducing maintenance requirements and associated costs.

Advanced Group Control for Maximum Performance

In multi-elevator installations, efficient group control is crucial for minimizing wait times and optimizing traffic flow. The NEXIEZ-MRL ver. 2 system incorporates Mitsubishi Electric's advanced ΣAI-22 and ΣAI-2200C group control systems, which leverage artificial intelligence to deliver superior performance.

These sophisticated control systems continuously analyze traffic patterns and adjust elevator operations in real-time to meet changing demand. By considering factors such as current and anticipated passenger loads, wait times, and energy efficiency, the system can make intelligent decisions about which elevator to assign to each call.

One of the key features of the ΣAI-2200C system is its ability to forecast near-future hall calls. By anticipating potential long-wait situations, the system can proactively assign elevators to minimize passenger waiting times. This predictive capability can significantly improve the overall efficiency of the elevator group, particularly during peak traffic periods.

For buildings with more complex traffic patterns, the NEXIEZ-MRL ver. 2 can be equipped with a Destination Oriented Allocation System (DOAS). This advanced system allows passengers to register their destination floor at the hall call station. The control system then assigns the most appropriate elevator based on factors such as current car position, load, and other registered calls. By grouping passengers with similar destinations, DOAS can significantly reduce travel times and improve overall system efficiency.

Space-Saving Design for Modern Architecture

The version 2 of NEXIEZ-MRL's machine-room-less design is a game-changer for modern architecture. By eliminating the need for a dedicated machine room, this innovative system frees up valuable space within a building, allowing for more flexible and efficient floor plans.

For architects and building designers, this elevator offers unprecedented flexibility. The absence of a machine room opens up new possibilities for roof design, potentially allowing for green roofs, rooftop gardens, or additional amenities. The NEXIEZ-MRL ver. 2 changes this paradigm by housing all major components within the hoistway itself.

In retrofit applications, the compact nature of the NEXIEZ-MRL makes it an ideal choice for upgrading older buildings where space is at a premium.

The space efficiency of this elevator also translates to cost savings. With no need to construct and maintain a separate machine room, building owners can reduce both initial construction costs and ongoing operational expenses.

Safety Features and Emergency Preparedness

Safety is a top priority in the design of the NEXIEZ-MRL ver. 2, with multiple layers of protection ensuring the well-being of passengers and the reliability of the system. Mitsubishi Electric has incorporated a comprehensive suite of safety features that meet or exceed industry standards.

The door safety devices of this elevator are equipped with advanced sensors that create a protective zone, preventing closure if any obstruction is detected. Depending on the type of sensor, the detection area differs, ensuring the safety of passengers of all sizes, including children and pets.

In the event of a power failure, the NEXIEZ-MRL ver. 2 is prepared. An optional operation by emergency power source allows the elevator to continue functioning using the building's backup power supply. If no backup power is available, a battery-powered Mitsubishi Emergency Landing Device (MELD) gently moves the car to the nearest floor and opens the doors, ensuring passengers can safely exit.

This elevator also includes features designed to respond to various emergency scenarios. The Firefighters' Emergency Operation (FE) mode, when activated, directs elevators to a designated floor, restricting elevator responses to firefighter-specific calls for rescue and firefighting tasks. Meanwhile, the Fire Emergency Return (FER) mode ensures passenger safety by automatically returning all elevators to a specified floor with doors open when a fire alarm or key switch is triggered, enabling efficient evacuation.

For regions prone to seismic activity, Earthquake Emergency Return (EER-P/EER-S) system can be integrated, allowing the elevator to stop at the nearest floor and open its doors when tremors are detected. These optional features aim to improve safety and streamline emergency responses during critical situations.

Raising the Future of Vertical Transportation

The Mitsubishi Electric NEXIEZ-MRL ver. 2 stands as a testament to what can be accomplished when innovative engineering is applied to the challenges of advanced urban living. It represents a new era in vertical transportation, one that prioritizes efficiency, sustainability, and user experience in equal measure. As buildings proceed to advance and develop, the NEXIEZ-MRL ver. 2 will without a doubt play a essential part in forming the vertical scenes of our cities, hoisting not passengers but the whole field of lift innovation.
