Illustrate as a example by three temperature controller C.
In multiple temperature controllers, used as the measured value of each temperature controller, default room sets room actual temperature T
, used as the setting value of each temperature controller, each temperature controller is according to room actual temperature T and room setting temperature for constant temperature degree Tsp
Degree Tsp generates wind-speed gear signal, used as the output of the temperature controller.Hereinafter illustrate in for cold season, above three temperature
The concrete control law of controller.
The output YA of the first temperature controller A is generated according to following control law：According to room actual temperature T and default room
Between design temperature Tsp calculate temperature deviation value, when the temperature deviation value is more than or equal to default first temperature deviation value and being less than
During default second temperature deviation (i.e. temperature deviation value is the little temperature difference), the first wind-speed gear signal is generated, work as temperature deviation
More than or equal to the default second temperature deviation and less than default 3rd temperature deviation value, (i.e. temperature deviation value is middle temperature to value
Difference) when and less than default 3rd temperature deviation value, generate the second wind-speed gear signal, when temperature deviation value it is pre- more than or equal to this
If the 3rd temperature deviation value (i.e. temperature deviation value be high temperature difference) when, generate the 3rd wind-speed gear signal；
It is understood that above-mentioned first temperature deviation value, second temperature deviation and the 3rd temperature deviation value can be by these
Art personnel rule of thumb set, and in the present embodiment, preferably the first temperature deviation value is 1 DEG C, second temperature is inclined
Difference is 2 DEG C, the 3rd temperature deviation value is 3 DEG C.

Sum, is assigned to n+1 n and goes to step 4, otherwise goes to step 3；In the present embodiment, the value of first bias a1
Scope is 1.5 DEG C～2 DEG C；
Step S3, if room actual temperature T is less than the room design temperature Tsp and default second bias a2
Difference, n-1 is assigned into n and step 4 is gone to, otherwise go to step 2；In the present embodiment, the value of second bias a2
Scope is 0.3 DEG C～0.5 DEG C；
Step S4, when the n is less than default lower limit b1, is assigned to the lower limit b1 n and goes to step S6, no
Then go to step S5；In the present embodiment, lower limit b1 is 1；
Step S5, when the n is more than default higher limit b2, is assigned to the higher limit b2 n and goes to step S6, no

Step S8, terminates.
It can be seen from the above, when in room, actual temperature T differs larger with room design temperature Tsp, gain is from whole
The n values for determining device E outputs are larger, also, when actual temperature T long-time in room cannot be adjusted to room design temperature Tsp, gain
Gain characteristics value n that Self-tuning System device E is exported will further increase.Therefore, gain characteristics value n is bigger, room actual temperature T
It is bigger with room design temperature Tsp differences, or room actual temperature T is adjusted into bigger to the difficulty of room design temperature Tsp.
With regard to above-mentioned selector D, output (i.e. gain characteristics value n) and each temperature controller of self-tuning gain device
Output (i.e. each wind-speed gear signal) respectively as the input of selector D, selector D be used for according to the gain characteristics
Value n, a wind-speed gear signal is selected as selector D's from the wind-speed gear signal of each temperature controller output
Output, is blown with controlling blower fan with the corresponding wind speed of wind-speed gear signal.
In the present embodiment, selector E specifically for：
When gain characteristics value is 1, the first temperature controller A is selected, control blower fan is with the output of the first temperature controller A
The corresponding wind speed of YA is blown；
When gain characteristics value is 2, second temperature controller B is selected, control blower fan is with the output of second temperature controller B
The corresponding wind speed of YB is blown；
When gain characteristics value is 3, the 3rd temperature controller C is selected, control blower fan is with the output of the 3rd temperature controller C
The corresponding wind speed of YC is blown.
It follows that when gain characteristics value n is bigger, corresponding to identical room actual temperature T and room design temperature Tsp
Deviation, the wind speed corresponding to the output of the selected temperature controllers of selector D is bigger, thus room actual temperature T and
Room design temperature Tsp differences it is bigger or by room actual temperature T adjust difficulty to room design temperature Tsp it is higher when, wind
The air supply velocity of machine is bigger, thus, it is possible to adjust in time and intelligently room actual temperature T.
According to the variable gain air-conditioner temperature control system that the present invention is provided, room can be deviateed according to room actual temperature
The degree auto-- tuning controller parameter of design temperature or control law, by way of adjustment air-conditioning heat exchange rate room is enabled
It is enough effectively to obtain suitable energy, meet the requirement of room comfort level.Air-conditioner temperature control system based on this principle can be with
The change of room load is effectively adapted to, the part room comfort level caused because of heating power imbalance using existing temperature controller can be overcome
Implacable defect.

Scope is 1.5 DEG C～2 DEG C；
Step S3, if room actual temperature T is less than the room design temperature Tsp and default second bias a2
Difference, n-1 is assigned into n and step 4 is gone to, otherwise go to step 2；In the present embodiment, the value of second bias a2
Scope is 0.3 DEG C～0.5 DEG C；
Step S4, when the n is less than default lower limit b1, is assigned to the lower limit b1 n and goes to step S6, no
Then go to step S5；In the present embodiment, lower limit b1 is 1；
Step S5, when the n is more than default higher limit b2, is assigned to the higher limit b2 n and goes to step S6, no
