Technical Field

[0001] The invention relates to the field of air quality feedback control, and in particular to a household central air-conditioning control method that is adaptive to indoor and outdoor environments. Background Art

[0002] As air conditioners become more popular, their share in residential and commercial electricity consumption continues to increase, leading to rising energy costs. Unscientific air conditioner usage habits will cause a lot of energy waste. Studies have found that air conditioning systems are electrical equipment that consumes the most electricity in homes or commercial offices;

[0003] Research has found that traditional air conditioning systems often fail to fully understand information such as indoor and outdoor temperature and humidity, and simply focus on controlling indoor temperature and humidity, causing users to feel uncomfortable. Especially when there is a large difference between indoor and outdoor temperature and humidity, users often set parameters that deviate greatly from the room temperature in order to quickly achieve a comfortable environment, which increases the energy consumption of the air conditioner. Traditional air conditioning system controllers, such as on / off controllers and PID controllers, are widely used due to their simple control logic, but these controllers have poor robustness when facing changes in the external environment, which may lead to uncertain control results.

[0004] Therefore, in the prior art, air conditioning systems generally lack effective adaptive indoor and outdoor temperature and humidity control capabilities, which leads to energy waste. Summary of the invention
