[0002] HVAC system is the main source of building energy consumption, and its energy consumption accounts for more than half of the total building energy consumption. While ensuring indoor temperature comfort, improving HVAC operating efficiency will help reduce energy consumption and carbon emissions. For the subsystem of HVAC system-air conditioning system, the key to energy saving lies in the effective matching of air conditioning system output cooling capacity and indoor load.

[0003] Currently, the temperature difference between the set temperature and the actual detected temperature is used to adjust the refrigeration or heating operating condition in air conditioning system. At the same time, the user's manual operation is relied on to control the on-off state of the air conditioner. In actual operation, it often happens that the door and window are also opened when the air conditioner is turned on, especially in public building areas, which is quite common, resulting in continuous leakage of cold / hot air, and the air conditioner needs to run for a long time to maintain the indoor temperature, causing unnecessary energy consumption.

[0004] When the door and window are opened, external temperature difference air enters the room, and the continued operation of air conditioning equipment also easily causes condensation of condensate at air outlet, causing slippery floor and ceiling mold, affecting the overall safety of the environment. This problem is mainly solved by daily energy-saving management measures, such as standardizing the operation of opening and closing doors and windows. However, the existing system mostly uses a simple management mode of one-size-fits-all in the linkage control of door and window opening and closing state and air conditioning management, without effectively considering the comfort experience of users, lacking automatic and refined linkage mechanism.
