Multi-split system

In public building energy consumption, central air conditioning accounts for approximately 60% of total energy usage, exceeding the combined energy consumption of lighting, elevators, and office equipment. Therefore, the focus of building energy conservation and emission reduction lies in the central air conditioning system.

Summary of Central Air Conditioning System Issues

lNo Remote Centralized Control

1.After entering a room, personnel manually set excessively low/high temperatures for rapid cooling/heating, failing to restore normal settings once the temperature is reached, resulting in significant energy waste;

2.Over-pursuit of low/high temperatures leads to prolonged high-load operation of air conditioners, poor comfort, severe energy waste, and reduced lifespan of the units;

3.Air conditioners remain operational during off-hours, holidays, and other unoccupied periods, wasting energy.

lNo Real-Time Data Monitoring

1.Inability to visually monitor air conditioner operation and data; remote real-time fault detection is unavailable, increasing the workload of inspection personnel;

2.Long data collection intervals may lead to omissions; network or program abnormalities in monitoring computers can cause billing issues.

lNo Data Analysis and Management

1.Management personnel cannot perform statistics, analysis, or management of energy data and consumption indicators for central air conditioning;

2.No alerts for abnormal electricity costs; inability to promptly control unreasonable increases in air conditioning electricity expenses.

Therefore, implementing energy-saving renovations for central air conditioning systems enables centralized control and real-time monitoring of operation status, preventing overcooling or overheating. This improves indoor comfort while reducing energy waste, lowers operational load and failure rates of air conditioners, enhances energy efficiency and operational management levels, visualizes centralized management and utilization rates, and reduces building operational electricity costs.

Air Conditioning Management Interface

The air conditioning management page allows selection of one or multiple cooling systems within the air conditioning system for individual or centralized management. Through management buttons, users can control power, set parameters, and view the number, address, and status of connected indoor units.

Air conditioning zone selection, indoor unit selection interface

The interface includes mode lock, function buttons identical to those on indoor units, and speed/temperature limits.
