The user-set parameters include set ambient temperature, set ambient humidity, startup period, etc. The number of rooms may be one, two, three, etc., but should be one or more. The user habit data acquisition and monitoring module can acquire user setting parameters.
Such as the set ambient temperature, set ambient humidity and on-time period of the end of room 1, room 2, and room 3 within 24 hours of the day of the work day and the day of the non-work day, respectively. On weekdays, the end start-up time of room 1 may be 6 to 8 a.m., 12 to 2 a.m., 6 to 11 a.m., the set ambient temperature is always 27 c, and the set ambient humidity is always 40%.

For example, the actual indoor environment temperature, the indoor environment humidity, the outdoor environment temperature and the outdoor environment humidity of the 1 st room, the 2 nd room and the 3 rd room in the starting period at the end of the working day and the non-working day are respectively obtained. On the workday, the actual indoor ambient temperature of room 1 fluctuates around 27 ℃, the indoor ambient humidity fluctuates around 40%, the outdoor ambient temperature is the real-time ambient temperature, and the outdoor ambient humidity is the real-time ambient humidity. The data acquisition is similar for room 2 and room 3.
3. And correcting the unit operation data according to the habit of the user among different rooms and the actual environment data.
And simultaneously, after user habit data and actual environment data of different rooms are obtained, the system control module controls the unit and the tail end to operate according to a built-in control program and corrects operation data.
The specific control method comprises the following steps:
1. The method comprises the steps of detecting the starting time and the end starting number of the unit, and comparing the starting time (t Machine for making food ) of the unit with the set starting time (t Machine tool ). 1) When t Machine for making food ≤t Machine tool , the unit belongs to the just-started stage, operates according to a built-in control program, and re-detects the starting time and the terminal starting number of the unit after deltat time, and performs the next cycle. 2) When t Machine for making food >t Machine tool , the unit belongs to a stable operation stage, and the actual parameters of different rooms are corrected to meet the set parameters of the user.

In summer, when Δt i≤T Is provided with and Δh i≤H Is provided with are not adjusted accurately, otherwise, f i(fi is determined as the compressor correction value of each room according to Δt i、ΔHi of each open-end room, and the initial f i =0) and the end on-off state are determined. In winter, when-DeltaT i≤T Is provided with , judging that the temperature of each room meets the requirement of a user, and not needing further adjustment accuracy, otherwise, respectively determining f according to DeltaT i、ΔHi of each open-end room i
In summer, f i for each open-ended room is determined as follows:
1) Delta T i>T Is provided with ,ΔHi>H Is provided with , the compressor needs to be increased in frequency, and f i is increased;
2) Δt i>T Is provided with ,-ΔHi>H Is provided with , compressor frequency unchanged, f i =0;
3) Delta T i>T Is provided with ,|ΔHi|≤H Is provided with , the compressor needs to be increased in frequency, and f i is increased;
4) Δt i>T Is provided with ,ΔHi>H Is provided with , compressor frequency unchanged, f i =0;
5) ΔT i>T Is provided with ,-ΔHi>H Is provided with , compressor need to be down-converted, reducing f i;
6) ΔT i>T Is provided with ,|ΔHi|≤H Is provided with , compressor need to be down-converted, reducing f i;
7) I ΔT i|≤T Is provided with ,ΔHi>H Is provided with , the compressor needs to be up-converted, increasing f i;
8) I deltat i|≤T Is provided with ,-ΔHi>H Is provided with , the compressor needs to be down-converted, reducing f i;
9) I Δt i|≤T Is provided with ,|ΔHi|≤H Is provided with , compressor frequency is unchanged, f i =0.
In winter, only the temperature difference is adjusted, and regardless of humidity, f i of each open-ended room is determined as follows:
1) ΔT i>T Is provided with , the compressor needs to be down-converted, reducing f i;
2) ΔT i>T Is provided with , the compressor needs to be up-converted, increasing f i;
3) The i Δt i|≤T Is provided with , compressor frequency is unchanged, f i =0.
After determining f i of each open-ended room, the final compressor correction value f Repair tool is obtained by averaging f i, and when the average value is obtained, the f i can be directly added and then averaged, and the maximum f i and the minimum f i can be removed and then averaged.
Such as f Repair tool ＝(f1+f2+f3+f4+f5)/5;
Or f 2 is the minimum and f 5 is the maximum, f Repair tool ＝(f1+f3+f4)/3
