Energy Saving Express
In today’s rapidly urbanizing world, high-rise buildings such as shopping malls, office buildings, and residential complexes have become the mainstream form of urban space. Elevators, as the core carriers of vertical transportation, directly affect the user experience of buildings. However, research data from the magazine “China Elevator” reveals a critical issue: elevators are typical high-energy-consuming special equipment, with a daily average power consumption of about 40 kW·h per elevator. This figure far exceeds that of other electrical equipment in buildings, aside from air conditioning, and accounts for as much as 20% of the total electricity consumption of buildings. How to control elevator energy consumption through technological means has become a focal point of concern for both the elevator industry and building management.
To solve the problem of high energy consumption in elevators, energy recovery devices have become a key technological support. The core principle of this device is that when the elevator is in a regenerative state, such as light-load upward or heavy-load downward, it converts the generated direct current into alternating current that meets the power quality standards of the grid, ultimately feeding it back to the grid for reuse. In simple terms, it efficiently converts the potential energy generated during elevator operation into electrical energy, thereby enhancing energy utilization efficiency from the source and significantly reducing building energy consumption costs.
But how can the energy-saving effects be quantified? The energy-saving dual-carbon monitoring system based on IoT technology provides the answer. This system is equipped with IoT modules, connects to the energy recovery device through an industrial gateway, and has installed electricity meters before the air switch for the elevator’s mains input, as well as electricity meters at the output end of the energy recovery device.The data from the energy recovery device’s related electricity meters has been integrated into the IoT system, allowing for real-time collection of core data such as recovered electrical energy, and seamlessly connecting to the cloud-based Elevator Energy Saving Dual-Carbon Monitoring Center via 4G network. This provides precise data support for monitoring elevator operating status and evaluating energy-saving effectiveness, aiding in the implementation of green energy-saving building construction.
The core value of this system is fully realized through three major functional modules:
1. Dynamic Energy Consumption Monitoring: Full-cycle Data Visualization
The system relies on IoT technology to achieve real-time collection of recovered electrical energy from elevators, presenting multi-dimensional recovery energy change curves over the year, month, and day through a visualization platform. It also supports precise tracing of historical data and cross-cycle comparative analysis, making the patterns of energy recovery fluctuations clear at a glance.
2. In-Depth Energy Efficiency Analysis: Quantifiable Energy Saving Benefits
Based on the collected data of recovered electrical energy and other full data, a professional analysis model is constructed to accurately calculate the elevator’s energy-saving rate and overall energy-saving benefits. These quantifiable data provide a scientific basis for formulating building energy optimization plans and for the technological iteration and upgrade of elevator equipment.
3. All-Scenario Remote Control: More Efficient Operation and Maintenance Collaboration
Utilizing IoT technology, a remote monitoring system covering multiple terminals such as mobile phones and computers is constructed, allowing managers and manufacturers to access elevator operating status and energy parameters at any time. The system can also provide real-time alerts for abnormal situations, significantly enhancing the efficiency of collaborative operation and maintenance across different entities.
From technical energy saving to data-driven energy management, this IoT-based monitoring system shifts elevator energy saving from “passive reduction” to “active control.” Under the guidance of dual-carbon goals, such intelligent solutions are injecting new momentum into the development of green buildings, making every kilowatt-hour of recovered electrical energy clearly visible.
