Abstract
The invention provides a method for controlling the frequency of a compressor, a device for controlling the frequency of the compressor and an air conditioner. The method for controlling the frequency of the compressor comprises the steps that after the air conditioner is started, if an initial set temperature is received, historical initial set temperatures in a time interval where the set moment of the initial set temperature is in are obtained, whether the initial set temperature is matched with the historical initial set temperatures or not is judged, and when a judging result is positive, the operation frequency of the compressor is controlled according to a received operation mode and historical temperature records in the time interval. According to the technical scheme, the air conditioner can have the self-learning capability, the frequency of the compressor of the air conditioner can be adjusted in real time according to the use habits of a user, so that the comfort degree experience of the user is improved, operation of the user is reduced, and the energy utilization efficiency is increased.
Description
Technical field
The present invention relates to air-conditioning technical field, in particular to control gear and a kind of air conditioner of a kind of controlling method of compressor frequency, a kind of compressor frequency.
Background technique
At present, parameters when air conditioner dispatches from the factory all relies on NBS, outdoor 35 DEG C/24 DEG C of the cooling condition mentioned in such as GB7725, indoor 27 DEG C/15 DEG C, namely air conditioner is the specific refrigeration system of specific Conditions Matching, such as the refrigeration agent that different Conditions Matchings is different rushes fluence, capillary pipe length and expansion valve opening etc., but when the real using air-condition of user, actual operating mode is difficult to meet this operating mode standard completely, and different geographical also can be different, the real internal and external environment temperature difference is also difficult to be consistent with GB, and user also can be variant in the use habit of different time.
But, in the controlling method of existing air conditioner, once after machine debugging, factory settings dispatches from the factory well parameter (as the initiation culture of air conditioner, maximum frequency of operation etc.) after, these parameters will be cured in air conditioner, cannot with the working condition adaptively modifying of reality, this just causes user in using air-condition device process, the adjustment of air conditioner is sensitive not, such as: in a period of time that user starts shooting at first, set temperature usually can be too low or too high, after running a period of time, after user's body temperature returns to normal, air conditioner still runs according to the parameter preset, frequency or elevated frequencies cannot be reduced in real time, this causes user to need manual tune temperature continually, the comfort level not only affecting user is experienced, and also reduce the utilization ratio of the energy.
Therefore, how to make air conditioner have ability of self-teaching, the compressor frequency of air conditioner can be regulated according to user's use habit in real time, experience with the comfort level improving user, reduce user operation, and improve efficiency of energy utilization, become problem demanding prompt solution.
Summary of the invention
The present invention is intended at least to solve one of technical problem existed in prior art or correlation technique.
For this reason, one object of the present invention is the controlling method proposing a kind of compressor frequency.
Another object of the present invention is the control gear proposing a kind of compressor frequency.
Another object of the present invention is to propose a kind of air conditioner.
For achieving the above object, embodiment according to a first aspect of the invention, propose a kind of controlling method of compressor frequency, comprise: after air conditioner start, if receive initial set temperature, then obtain the history initial set temperature in the time interval that moment place is set of described initial set temperature; Judge whether described initial set temperature mates with described history initial set temperature, and when judged result is for being, the operation frequency of compressor according to the historical temperature record controls in the operating mode received and described time interval.
The controlling method of compressor frequency according to an embodiment of the invention, by judging whether the initial set temperature that the rear air conditioner of this start receives mates with the history initial set temperature that the same period (same time interval) receives after starting shooting, can judge that whether working condition when this is started shooting is consistent with the history working condition of same period, if this initial set temperature and this history initial set temperature match, then illustrate that working condition when this is started shooting is consistent with the history working condition of same period, air-conditioning then can be made according to the operation frequency of the historical temperature record controls compressor in operating mode and this time interval, thus make air conditioner have self-teaching and judgement, the operation frequency of compressor can be controlled adaptively according to the history use habit of user, this comfort level that not only can improve user is experienced, reduce user operation, also be conducive to improving efficiency of energy utilization simultaneously.
Certainly, can judge that in order to make air conditioner whether working condition when this is started shooting is consistent with the history working condition of same period more exactly, this time interval can be refined to date Hour Minute Second, and 24 of every day hour can be divided into multiple time interval as much as possible.
