Abstract

The present invention relates an automatic adjusting control system which is able to automatically adjust an operation setting value thereof according to the air-conditioning environmental conditions and the changes of load or the requirements of users. The control system mainly includes a plurality of air-conditioners, a plurality of sensors, a central control unit which is able to compare the operation setting value with values detected by each of the sensors to produce a mating signal, and a plurality of control boxes being able to control the operation of each of the air-conditioners according to the mating signal supplied from the central control unit so as to adjust the air-conditioning effect and to save energy.

Claims

1. An automatic adjusting control system adapted to automatically adjust an operation setting value thereof according to the air-conditioning environmental conditions and the changes of load or the requirements of users;

the control system comprising;

a plurality of air-conditioners,

a plurality of sensors,

input means for receiving a user-entered standard temperature set value for the control system and a user-entered temperature set value for each of the air-conditioners,

at least one central processing unit operably configured to automatically generate the operation setting value for at least one of the air-conditioners responsive to a comparison of the temperature set value of the air-conditioner and the standard temperature set value of the control system; and

, to compare the operation setting value with values detected by at least one sensor corresponding to the air-conditioner to produce a mating control signal therefor, and

a plurality of control boxes each attached to a respective one of the air-conditioners, each of the control boxes controlling the operation of each of the air-conditioners according to the mating control signal supplied therefor generated by the central processing unit so as to adjust the air-conditioning effect and to save energy.

2. The automatic adjusting control system as claimed in claim 1, wherein when the difference between a standard temperature set value of the control system and a temperature set value of each of the air-conditioners exceeds a pre-determined value, the control system is adapted to stepwise increase the operation setting value thereof during a pre-determined interval of time, so as to moderately vary the temperature of each of the air-conditioners.

3. The automatic adjusting control system as claimed in claim 1, wherein assuming QS is a fixed amount of electricity consumption of the contract capacity of a building, and Q0 is an amount of electricity consumption of the control system, when QS≦

Q0 the standard temperature set value is chosen as the operating setting value of the control system, and is output from the central control unit, thereby preventing the electricity overloading.

4. The automatic adjusting control system as claimed in claim 1, wherein the control system is adapted to control the operation thereof according to the difference between the ambient temperature and the standard temperature set value, thereby preventing the variation of temperature from changing excessively.

5. The automatic adjusting control system as claimed in claim 1, wherein the control system is connected to a computer which calculates the total electricity consumption of all of the users so as to control the operation of the air-conditioners.

6. The automatic adjusting control system as claimed in claim 1, further comprising a central control unit coupled to the central processing unit connected to signals supplied by a foreign power supply management unit which is able to drive the operation of the air-conditioners.
