AI Technical Summary
Existing multi-split air conditioning systems ignore the operating status of indoor units and real-time temperature deviations when determining the system load ratio, resulting in inaccurate load calculations and an inability to accurately switch the four-way valve status, thus affecting system operating efficiency.
Design a multi-split air conditioning system that acquires the operating status parameters of indoor units in real time, maps them to heating or cooling load contributions, calculates the total heating and cooling load indicators, and determines the mode migration conditions based on these indicators, smoothly switching the operating mode of the outdoor heat exchanger to avoid overload or energy redundancy.
It achieves efficient and smooth switching under different load conditions, ensuring system stability and efficiency, avoiding frequent mode switching, and adapting to the differences in heating and cooling needs in different regions.
