For the convenience of understanding, two embodiments of the room temperature probe timing detection and the real-time monitoring are respectively further described.
In the first mode, during dehumidification control, the room temperature probe regularly detects the indoor environment temperature T1, and preferably monitors the indoor environment temperature T1 every 1min to compare with the set temperature Ts:
when the difference between the indoor environment temperature T1 and the set temperature Ts is detected to exceed the rated maximum temperature value (namely, T1-Ts is more than or equal to 8 ℃), the indoor environment temperature T1 is far higher than the set temperature Ts, so that the first inner fan 8 and the second inner fan 9 are controlled to be switched to high wind to operate, the circulation of indoor air and the heat exchange rate of the indoor air and the indoor heat exchanger 77 are greatly accelerated, and the indoor environment temperature T1 is convenient to rapidly drop;

when the difference between the indoor environment temperature T1 and the set temperature Ts is detected to be between the rated second temperature value and the first temperature value (namely, T1-Ts is more than or equal to 3 ℃) and less than 5 ℃), the indoor environment temperature T1 is within a reasonable range, so that the first inner fan 8 and the second inner fan 9 are controlled to be switched to low-wind operation, the circulation of indoor air and the heat exchange with the indoor heat exchanger 77 are ensured, and the indoor environment temperature T1 is maintained;
when the difference between the indoor environment temperature T1 and the set temperature Ts is detected to be lower than the rated second temperature value (i.e., T1-Ts < 3 ℃), it means that the indoor environment temperature T1 is relatively low, so as to control the first inner fan 8 to switch to the low wind operation and the second inner fan 9 to stop operating (in the same way, or control the first inner fan 8 to stop operating and the second inner fan 9 to switch to the low wind operation), slow down the circulation of the indoor air and the heat exchange speed with the indoor heat exchanger 77, so that the indoor environment temperature T1 gradually and slowly rises; in addition, if the indoor environment temperature T1 is detected to continuously drop and the difference value between the indoor environment temperature T1 and the set temperature Ts is lower than the rated protection temperature value (namely, T1-Ts is less than 2 ℃), the indoor environment temperature T1 is too low, so that the air conditioning system is closed, and the first inner fan 8 and the second inner fan 9 stop running until the air conditioning system reaches the preset refrigeration starting condition and then is electrified to run.

When the difference between the indoor environment temperature T1 and the set temperature Ts is detected to exceed the rated temperature drop amplitude of 1.5 times (namely, T1-Ts is more than or equal to 1.5ut ℃), the indoor environment temperature T1 is far higher than the set temperature Ts, so that the first inner fan 8 and the second inner fan 9 are controlled to be switched to high wind to operate, the circulation of indoor air and the heat exchange rate of the indoor air and the indoor heat exchanger 77 are greatly accelerated, and the indoor environment temperature T1 is convenient to drop rapidly;
when the difference between the indoor environment temperature T1 and the set temperature Ts is detected to be between the rated 1-1.5 times of temperature drop amplitude (namely, ut is less than T1-Ts is less than 1.5ut ℃), the indoor environment temperature T1 is higher, so that the first inner fan 8 is controlled to be switched to the low-wind operation and the second inner fan 9 is controlled to be switched to the high-wind operation (in the same way, or the first inner fan 8 is controlled to be switched to the high-wind operation and the second inner fan 9 is controlled to be switched to the low-wind operation), the circulation of the indoor air and the heat exchange rate of the indoor air and the indoor heat exchanger 77 are accelerated, and the indoor environment temperature T1 is gradually and slowly reduced;
when the difference between the indoor environment temperature T1 and the set temperature Ts is detected to be between the rated second temperature value and 1.5 times of temperature reduction amplitude (namely, T1-Ts is more than or equal to 3 ℃ and less than ut ℃), the indoor environment temperature T1 is in a reasonable range, and therefore the first inner fan 8 and the second inner fan 9 are controlled to be switched to low-wind operation, circulation of indoor air and heat exchange with the indoor heat exchanger 77 are guaranteed, and the indoor environment temperature T1 is maintained;
when the difference between the indoor environment temperature T1 and the set temperature Ts is detected to be lower than the rated second temperature value (i.e., T1-Ts < 3 ℃), it means that the indoor environment temperature T1 is relatively low, so as to control the first inner fan 8 to switch to the low wind operation and the second inner fan 9 to stop operating (in the same way, or control the first inner fan 8 to stop operating and the second inner fan 9 to switch to the low wind operation), slow down the circulation of the indoor air and the heat exchange speed with the indoor heat exchanger 77, so that the indoor environment temperature T1 gradually and slowly rises; in addition, if the indoor environment temperature T1 is detected to continuously drop and the difference value between the indoor environment temperature T1 and the set temperature Ts is lower than the rated protection temperature value (namely, T1-Ts is less than 2 ℃), the indoor environment temperature T1 is too low, so that the air conditioning system is closed, and the first inner fan 8 and the second inner fan 9 stop running until the air conditioning system reaches the preset refrigeration starting condition and then is electrified to run.
Further, the dehumidification regulation mode of the embodiment is as follows: when the air conditioning system is powered on for dehumidification, the difference value between the indoor environment temperature T1 detected by the room temperature probe and the set temperature Ts exceeds the preset temperature 3 ℃ (namely T1-Ts is not less than 3 ℃), then the air conditioning system is judged to need to start dehumidification regulation, wherein under the dehumidification regulation, the first inner fan 8 and the second inner fan 9 are both switched to low wind, after the opening degree of the electronic expansion valve 6 is cleared, the air conditioning system continuously operates for a section according to the rated opening degree (the expansion valve 6 of the electronic expansion valve 6 is firstly 960P to ensure that the opening degree is cleared, and then operates for 5 minutes at the opening degree of 304P), then the opening degree of the electronic expansion valve 6 is dynamically regulated correspondingly based on the middle actual temperature of the indoor heat exchanger 7, and simultaneously the room temperature probe is started to timely/real-timely monitor the indoor environment temperature T1 correspondingly in a one or two way, so that the.
Further, in the cooling and starting condition of the embodiment, the difference between the detected indoor environment temperature T1 and the set temperature Ts is higher than 0 ℃, that is, T1-Ts is greater than 0 ℃, and the air conditioning system can be powered on to operate after reaching the cooling condition.
