The preset third temperature may be a temperature set by the user plus 3 or a temperature set by the user plus 5, and may be set according to the user's requirement. When the cooling mode is continuously operated, if the indoor temperature is higher than the preset first temperature, for example, the indoor temperature is higher than the temperature +1 set by the user, the wind speed gear can be adjusted from the low speed to the medium speed, so that the indoor temperature is slowly reduced to the temperature set by the user, and when the temperature reaches the temperature set by the user, the wind speed gear can be adjusted from the medium speed to the low speed.

it should be noted that, when the vehicle is just started, the heating mode needs to be started to quickly raise the indoor temperature, and at this time, the indoor temperature is low, that is, the difference between the indoor temperature and the indoor temperature set by the user is large, and the high-speed gear needs to be started to quickly raise the temperature. That is, when the indoor temperature is higher than the preset fourth temperature, the air speed is adjusted to a high speed after the heating valve is opened, so that the indoor temperature can be quickly raised, and when the temperature is adjusted to the temperature set by the user, the air speed can be adjusted to a low speed. The preset fourth temperature may be the temperature set by the user minus 3 or the temperature set by the user minus 5, and may be set according to the user's requirement. When the heating mode is continuously operated, if the indoor temperature is lower than the preset second temperature, for example, the indoor temperature is lower than the temperature-1 set by the user, the wind speed gear can be adjusted from the low speed to the medium speed, so that the indoor temperature is slowly increased to the temperature set by the user, and when the temperature reaches the temperature set by the user, the wind speed gear can be adjusted from the medium speed to the low speed.
Specifically, control module can be through comparing the accurate temperature data who will gather with the indoor temperature that the user set for to adjust indoor temperature in real time, for example can adjust the wind speed gear, make indoor temperature reach user's the settlement temperature fast, realize intelligent temperature regulation. For example, when refrigeration is needed, the indoor temperature is greater than a preset first temperature, the air speed gear is opened to an intermediate speed gear after the refrigeration valve is opened, the air speed gear is opened to a high speed gear when the indoor temperature is greater than a preset third temperature, and the air speed gear can be adjusted to a low speed gear when the indoor temperature reaches the indoor temperature set by a user, wherein the preset third temperature and air speed gear should be greater than the preset first temperature. Similarly, if the indoor temperature is lower than the preset second temperature, the air speed gear is shifted to the medium speed gear after the heating valve is opened, if the indoor temperature is lower than the preset fourth temperature, the air speed gear is shifted to the high speed gear, and if the indoor temperature reaches the indoor temperature set by the user, the air speed gear can be adjusted to the low speed gear. Or the wind speed gear can be adjusted according to the instruction of the user.
