When the difference between the new current indoor temperature and the set temperature is less than the second preset difference and the new current indoor temperature is within the preset comfort temperature range, it means that the new current indoor temperature is closer to the set temperature or is different from the set temperature. When the set temperatures are equal and the new current indoor temperature is more comfortable, the surrounding air supply is executed and the indoor fan speed is reduced to 42°C to achieve soft air flow. When the difference between the new current indoor temperature and the set temperature is greater than or equal to the second preset difference or the new current indoor temperature is not within the preset comfort temperature range, explain the new current indoor temperature and the preset temperature. The difference is large, or the new current indoor temperature is not the preset comfort temperature, return to step S152, that is, execute the fourth air supply mode to enable the air conditioner to quickly cool or heat.
