Preferably, the low-temperature heating mode further includes, for example: when the air conditioner 200 is shut down several times when it reaches a temperature, the set wind speed F is adjusted downward.
For example, when the user sets strong wind F1In time, and after the shutdown is continuously performed for a plurality of times at the temperature, the air conditioner 200 will automatically set the wind speed F to the high wind level F2(ii) a After several times of shutdown at a high temperature, the air conditioner 200 will automatically set the wind speed F to the neutral wind level F3And so on until the low wind gear F is set4。
Specifically, the air speed with higher strength enables the air conditioner 200 to be continuously stopped at a warm state for multiple times, which indicates that the heating capacity of the air conditioner 200 is too large, and the heating and heat dissipation balance cannot be achieved, so that the air speed F is reduced, the heating and heat dissipation balance is realized, the damage of oil shortage and the like caused by frequent startup and shutdown of the compressor is avoided, and the service life of the compressor is prolonged.
Preferably, the plurality of times of temperature-reaching shutdown can be set to be 7-10 times.
