The split-type air conditioner energy-saving control system is developed based on the refined management of building energy consumption. It adopts advanced sensing technology, Internet of Things and Internet technology and database technology to realize the remote monitoring of split-type air conditioner power consumption and indoor temperature, and the use of air conditioners. Power consumption analysis, and through flexible energy-saving strategies and means such as temperature control, timing control, and remote control by administrators, the rational use of air conditioners can be effectively controlled, which can not only create a comfortable living and production environment without causing energy waste, but also realize the Precise measurement of energy consumption for individual air conditioners provides measurement tools and energy-saving means for quantifying energy-saving targets.

The system is mainly designed for the application scenarios of split air conditioners such as power transformation and distribution rooms, elevator machine rooms, and public areas. By matching control strategies suitable for equipment room management, it can realize remote control of air conditioners and reduce energy consumption, while ensuring that electromechanical equipment operates at a suitable It can reduce the failure rate of equipment and ensure the safety of personnel and property.

The system mainly monitors the operating parameters such as air conditioning operation mode, indoor temperature, set temperature, and electricity on-line, collects it periodically, and then conducts statistics and analysis of the data. On this basis, a corresponding air conditioning energy saving management model is established. Centralized control, temperature alarm, operation failure alarm and other comprehensive energy-saving early-warning means, and finally achieve the energy-saving operation management of online air conditioners.
