In recent years, as the living standard of people is improved, the requirement for the comfort level of the indoor environment is higher and higher. To improve the comfort of the indoor environment, air conditioners are becoming an increasing choice for multiple users to adjust the temperature of the indoor environment.

Generally, when the outdoor ambient temperature is high, a user needs the air conditioner to operate in a cooling mode to lower the indoor ambient temperature; when the outdoor ambient temperature is low, the user needs the air conditioner to operate in the heating mode to raise the indoor ambient temperature.
