judging whether the difference value between the real-time temperature value and the preset temperature value is larger than or equal to the preset temperature difference value;
when the difference between the real-time temperature value and the preset temperature value is greater than or equal to the preset temperature difference, the controller 40 controls the air conditioner indoor unit to operate in a normal operation mode; that is, in this case, the indoor air pollution is not serious, but the indoor temperature is relatively hot or relatively cold, and it is necessary to preferentially adjust the indoor temperature to a comfortable temperature, increasing the user's comfort.
And when the difference between the real-time temperature value and the preset temperature value is less than the preset temperature difference, the controller 40 controls the air conditioner indoor unit to operate in the purification operation mode. That is, in this case, the indoor temperature is already relatively suitable, and no adjustment is required for the indoor temperature, and at this time, the indoor unit of the air conditioner is operated in the purification operation mode to adjust the indoor air quality, so that the indoor air quality is restored to the healthy state as soon as possible.
In this embodiment, as shown in fig. 7, when the user turns on the air conditioner, the PM2.5 monitoring sensor 30 operates in the intelligent purge mode by default, and detects the indoor real-time PM2.5 value; when the real-time PM2.5 value is in the heavy pollution range, the air conditioner operates for a period of time t according to the purification mode, then detects the real-time PM2.5 value again, if the real-time PM2.5 value is reduced to the healthy range, the air conditioner operates according to the conventional operation mode, if the real-time PM2.5 value is reduced to the light pollution range, operates according to the mode that the PM2.5 value is in the light pollution range, if the real-time PM2.5 value is still in the heavy pollution range, continues to operate for a period of time t according to the purification mode, and circulates until the real-time PM2.5 value is reduced to the light pollution range or the healthy range; when the real-time PM2.5 value is in a light pollution range, detecting a difference value between the indoor real-time temperature value and a preset temperature value set by a user through a remote controller, if the difference value is smaller than 2 degrees, operating the air conditioner in a purification mode for a period of time, then detecting the PM2.5 value again, if the difference value is larger than or equal to 2 degrees, operating the air conditioner in a conventional operation mode for a period of time t, then detecting the difference value between the indoor real-time temperature value and the preset temperature value set by the user through the remote controller again, if the difference value is still larger than or equal to 2 degrees, continuing to operate the air conditioner in the conventional operation mode for a period of time t, and circulating until the difference value is smaller than 2 degrees; when the real-time PM2.5 value is in the healthy range, the air conditioner is operated in the normal operation mode.
When the indoor air is cleaned to a healthy range after the air conditioner is started for a period of time, the air conditioner operates in a normal operation mode, the PM2.5 monitoring sensor 30 keeps monitoring the real-time PM2.5 value of the indoor air according to a certain period, and when a user opens or opens a window to enable the outdoor air to enter the room to pollute the indoor air again, the PM2.5 monitoring sensor 30 can respond quickly, and the air conditioner enters a corresponding cleaning operation mode according to the detected pollution degree until the indoor air reaches the healthy range again.
The control panel or the remote controller of the indoor unit of the air conditioner is provided with a rapid purification button, after the air conditioner is started, the system can automatically judge whether the indoor unit of the air conditioner is in a rapid purification mode, if the indoor unit of the air conditioner is in the rapid purification mode, and when a user wants to purify indoor air as soon as possible, the user can directly switch the default intelligent purification mode into the rapid purification mode by pressing the rapid purification button on the control panel or the remote controller, in the rapid purification mode, the haze removal filter screen 10 closes the air inlet 20, the air conditioner operates in the rapid purification mode until the real-time PM2.5 value is reduced to a healthy range, then operates in the conventional operation mode, and the air conditioner is automatically switched into the intelligent purification mode. The healthy range of PM2.5 values refers to a range of PM2.5 values suitable for the user to breathe.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
