Air conditioners are becoming more and more widely used, and the proportion of air conditioners' electricity consumption in total electricity consumption continues to rise. The energy consumption of air conditioners has already accounted for about 60% of the total energy consumption. At the same time, in the design of air-conditioning systems and equipment selection, the maximum load is used as the design working condition, while the actual operation of the air-conditioning load varies with various factors, the minimum is less than 10% of the design load, then there are large Energy waste. Therefore, how to adapt the air-conditioning system to high-efficiency and energy-saving operation under low load and energy-saving selection of equipment in system design has become the key to energy saving.

The system comprehensively collects indoor and outdoor environmental parameters of each control point, according to the actual load of the system and the needs of the terminal cold and heat sources to achieve comprehensive control of the operation energy efficiency of all links of the system, real-time tracking control of the terminal air conditioning, fresh air and water circulation system equipment operation Efficiency, optimize and adjust the operating cycle of the host, and achieve a comprehensive increase in the energy efficiency of the entire central air conditioning system.
