Air conditioner control method and system and air conditioner

Abstract

The invention provides an air conditioner control method and system and the air conditioner. The control method of the air conditioner in an automatic mode comprises the steps that the outdoor environment parameter value is detected; whether the outdoor environment parameter value is larger than or equal to a first preset threshold value or not is judged; when the outdoor environment parameter value is smaller than the first preset threshold value, a fresh air mode is started, the air conditioner enters a refrigeration or heating mode, and when the outdoor environment parameter value is no smaller than the first preset threshold value, the indoor environment parameter value is detected; whether the indoor environment parameter value is larger than or equal to a first preset threshold value or not is judged; when the indoor environment parameter value is smaller than the first preset threshold value, the air conditioner is controlled to enter the refrigeration or heating mode, and when the indoor environment parameter value is no smaller than the first threshold value, the outdoor environment parameter value and the indoor environment parameter value are compared; and according to the comparison result, the ventilation mode of the air conditioner is determined. Through the air conditioner control method, the effects that the indoor air quality and the outdoor air quality are monitored in real time and compared to determine the ventilation mode of the air conditioner are achieved, the good indoor air quality is ensured, and multifunctional selection requirement of a user for the air conditioner is met.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner control method, a control system and an air conditioner. Background technique [0002] In the prior art, when the air conditioner is working, the indoor doors and windows need to be closed under normal circumstances, and the air is taken in from the room, and after being refrigerated or heated by the air conditioner, the air is discharged back into the room. As time goes by, the oxygen content in the room Gradually decreasing, the CO2 concentration continues to increase, and the air is turbid, which is not conducive to human health; in addition, the outdoor smog pollution is becoming more and more serious, and whether the outdoor air is suitable for opening the fresh air function is a technical problem that has not yet been resolved. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems ...
