Invention is further described in detail.
Fig. 1 is referred to, which show the flow chart based on air conditioner control method for frequency one embodiment of the present invention.Such as
Shown in Fig. 1, the method which realizes FREQUENCY CONTROL includes the following steps the process constituted：
Step 11：Air conditioner is switched on, and compressor operating is controlled according to original frequency.
Air conditioner booting after, first, in accordance with original frequency control compressor operating, specifically, be outdoor unit after the power is turned on,
Outdoor unit controls compressor operating according to original frequency.
For original frequency, various ways determination may be used.
As an implementation, original frequency is fixed frequency.That is, every time after air conditioner booting, outdoor unit is
Control compressor is run using fixed frequency as original frequency.Fixed frequency is known, is stored in outdoor unit memory
One frequency values, outdoor unit after the power is turned on, read the fixed frequency value from memory, and control compressor is transported with the fixed frequency
Row.As a preferred embodiment, fixed frequency is compressor maximum frequency of operation.That is, after air conditioner booting, control pressure
Contracting machine is run with maximum frequency of operation, to realize the maximum cooling capacity or heating capacity of system, with most fast speed to indoor progress
Temperature is adjusted, and achievees the purpose that fast regulating temperature, improves the indoor quick comfort conditioning of air conditioner initial operating stage.Moreover, every time
Compressor frequency control is directly carried out using fixed frequency as original frequency, control mode is easy, easy to implement.
As another embodiment, original frequency is not changeless frequency, but according to indoor environment temperature
The frequency values determined with outdoor environment temperature.Specifically, air conditioner is switched on, according to original frequency control compressor fortune
Row, including：Air conditioner is switched on, and obtains practical indoor environment temperature when booting and practical outdoor environment temperature, calculates practical room
The practical temperature difference between interior environment temperature and the practical outdoor environment temperature, it is corresponding with original frequency according to the known temperature difference
Relationship and the practical temperature difference determine practical original frequency corresponding with the practical temperature difference, and compressor is controlled according to practical original frequency
Operation.
Wherein, the correspondence of the temperature difference and original frequency is stored in advance in the memory of air conditioner.Also, the temperature difference with just
The correspondence of beginning frequency meets：The temperature difference is bigger, and original frequency is higher.The correspondence of the temperature difference and original frequency is determined in this way
Purpose is, in air conditioner booting initial operating stage, the temperature difference of indoor and outdoor is reduced with most fast speed, improves what indoor temperature was adjusted
Comfort.After air conditioner booting, practical indoor environment temperature when just booting and practical outdoor environment temperature are obtained, calculates two
The practical temperature difference between person；It searches or calculates corresponding to the practical temperature difference from the correspondence of the known temperature difference and original frequency
Original frequency, as practical original frequency；Then, outdoor unit controls compressor operating according to practical original frequency
In some other embodiment, air conditioner booting controls compressor operating according to original frequency, can also use following
Method：
If air conditioner is to power on booting for the first time, fixed frequency is selected to control compressor operating as original frequency.For example, selection pressure
Contracting machine maximum frequency of operation is as original frequency, and after air conditioner powers on booting for the first time, control compressor is with maximum frequency of operation

Original frequency corresponding to the secondary run time shut down up to temperature is practical original frequency.It is reached for the first time that is, prestoring temperature detector
The correspondence for the run time and original frequency that temperature is shut down.Also, the correspondence meets：When reaching the operation that temperature is shut down for the first time
Between it is longer, corresponding original frequency is bigger.So determine the correspondence for reaching run time and original frequency that temperature is shut down for the first time
Purpose be, reach that the run time that temperature is shut down is longer for the first time, show indoor temperature reach target temperature time it is longer, it is indoor
The speed that temperature is adjusted is slower, shows that original frequency is too small.To improve the speed that indoor temperature is adjusted, then booting is powered in next time
Afterwards, increase the original frequency of compressor.Before the shutdown of each air conditioner, this time booting temperature detector will be stored and reach what temperature was shut down for the first time
Run time.After the booting of next air conditioner, read first stored last time power on booting operation after temperature detector reach temperature for the first time
The run time of shutdown determines practical original frequency；Then, control compressor is run with practical original frequency.

Temperature and shut down.For reduce energy consumption, also for avoid temperature detector frequently reach temperature shut down and cause it is uncomfortable, will control compressor frequency reducing
Operation.And it sets raising frequency condition and includes：The practical run time shut down up to temperature is more than the run time that setting is shut down up to temperature, or
Person, the practical frequency shut down up to temperature are less than the frequency that setting is shut down up to temperature.If the practical run time shut down up to temperature is big, or
The practical frequency shut down up to temperature is low, shows to run under current frequency, it is difficult to reach temperature detector and be shut down up to temperature.In this case,
The comfort that temperature is adjusted is improved to make indoor temperature rapidly reach or approaching target temperature, then will control compressor liter
Frequency is run.
In some other preferred embodiment, also the amplitude of the amplitude of frequency reducing or raising frequency work will be quantified and be limited, with
Improve the accuracy of compressor frequency control.Specifically, if using the run time shut down up to temperature as control foundation, if
The run time that Ding Dawen is shut down is multiple, and the run time that multiple settings are shut down up to temperature forms the fortune that multiple settings are shut down up to temperature
Row time range.
So, the practical run time shut down up to temperature of temperature detector is obtained, the run time shut down up to temperature with setting is made comparisons,
It specifically includes：The practical run time shut down up to temperature of temperature detector is obtained, the run time shut down up to temperature with setting is made comparisons, determined
The run time range that setting belonging to the practical run time shut down up to temperature is shut down up to temperature.
