Abstract

A kind of air-conditioning temperature control method provided by the invention uses closed-loop control, environment temperature is detected using temperature sensor and is compared with the temperature preset value of air-conditioning, and then select the controller of different control algolithms that temperature is adjusted according to more resulting difference, to allow detection temperature to track always to air-conditioning preset temperature, finally make temperature detection value equal with air-conditioner temperature preset value.Very good solution environment temperature and the larger problem of air-conditioning preset temperature deviation in the prior art.

Description

Air-conditioning temperature control method

Technical field

The present invention relates to household appliance technical field, especially a kind of air-conditioning temperature control method.

Background technique

Traditional air-conditioning mostly uses greatly opened loop control, not the feedback of environment temperature, and after air-conditioner temperature setting, i.e., one is a certain Determining Power operation usually makes the preset temperature deviation of environment temperature and air-conditioning larger, it is difficult to reach ideal effect in this way Fruit.

Summary of the invention

To solve above-mentioned the technical issues of being previously mentioned in the prior art, the present invention provides a kind of air-conditioning temperature control method, specifically Scheme is as follows:

A kind of air-conditioning temperature control method, which is characterized in that use closed-loop control, detect environment temperature using temperature sensor, and will For temperature feedback to the comparator in air-conditioning, comparator calculates the difference of air-conditioner temperature preset value and detected value, industrial personal computer according to Air-conditioner temperature preset value from the size of the difference of detected value uses the controller of different control algolithms so that temperature to be adjusted, Finally keep temperature detection value equal with air-conditioner temperature preset value.

Compared with prior art, a kind of air-conditioning temperature control method provided by the invention uses closed-loop control, utilizes temperature sensing Device detection environment temperature is simultaneously compared with the temperature preset value of air-conditioning, and then selects different controls according to more resulting difference Temperature is adjusted in the controller of algorithm, so that detection temperature be allowed to track always to air-conditioning preset temperature, finally makes Temperature detection value is equal with air-conditioner temperature preset value.In the prior art environment temperature and air-conditioning preset temperature are inclined for very good solution The larger problem of difference.

Specific embodiment

The invention will be further described below.

The present embodiment provides a kind of air-conditioning temperature control method, this method uses closed-loop control, detects ring using temperature sensor Border temperature, and environment temperature is fed back into the comparator in air-conditioning, comparator calculates air-conditioner temperature preset value and temperature sensing The difference of device detected value, industrial personal computer is according to air-conditioner temperature preset value from the size of the difference of temperature sensor detected value and using different Control algolithm controller temperature to be adjusted, finally make temperature detection value equal with air-conditioner temperature preset value.Usually In the case of, P algorithmic controller is used when air-conditioner temperature preset value differs larger with temperature sensor detected value, herein P algorithm Controller, i.e. proportional controller.It is controlled when air-conditioner temperature preset value and temperature sensor detected value are close using pid algorithm Device, herein pid algorithm controller, that is, proportional plus integral plus derivative controller.Different temperature gaps is made using different algorithmic controllers The preset value of air-conditioner temperature can be quickly achieved by obtaining environment temperature.Compared with prior art, this method has well solved existing There is in technology environment temperature differ larger technical problem with air-conditioning preset temperature.

Although by reference to preferred embodiment, invention has been described, the case where not departing from the scope of the present invention Under, various improvement can be carried out to it and can replace component therein with equivalent.Especially, as long as there is no structures to rush Prominent, items technical characteristic mentioned in the various embodiments can be combined in any way.The invention is not limited to texts Disclosed in specific embodiment, but include all technical solutions falling within the scope of the claims.
