Intelligent control
By monitoring all parameters, the intelligent control logic decides the best load adjustment method, it optimizes the EXV and the capacity slider to guarantee safe operation under various load conditions.
Conventional BMS systems only focus on the interlock control, operation status and parameter monitoring, which achieves automation and energy management, Midea centralized energy management system attaches importance to building load prediction and control, and coordinates the operation of air-conditioner, fan and water pumps to realize optimum energy management.

System control functions:
● Pragmatic control modes
● Equalized operation time
● Optimum operation schedule
● System data report
● Strategies to address problems
● Remote communication function
Intelligent control

Advanced oil system
Adoption of special oil separation and return system and the built-in oil separator ensure the systems’ stability.
The lubrication system can heat oil to match the chillers exact requirements, guaranteeing the system is always protected against unnecessary wear.
