In order to make the objectives, technical solutions, and advantages of the present invention clearer, below with reference to drawings and examples,
Invention is further described in detail.
Referring to Figure 1, which show the flow chart based on the air condition of that present invention progress control method one embodiment, tool
It is the progress control method flow chart of the one embodiment for taking into account amenity and compressor operational efficiency for body.
As shown in Figure 1, the method that the embodiment realizes air conditioner operation control includes the following steps that the winding to be formed switches
Control process:
Step 101: the temperature difference between real-time room temperature and room temperature target value is calculated, the indoor temperature difference in real time is obtained, it will be real
When room in the temperature difference set indoor temperature difference threshold with first and make comparisons.
It is obtained in real time in air conditioner booting operational process, according to setting using frequency specifically, real-time room temperature refers to
The temperature in room locating for the air conditioner taken.The acquisition of the real-time room temperature can be realized using the prior art, for example, passing through
Air-conditioning air inlet or temperature sensor detection and acquisition inlet air temperature close to the position of air-conditioning air inlet are set, as reality
When room temperature.Room temperature target value refers to that set by user or air conditioner is set automatically, expectation is indoor achieved
Target temperature.The indoor temperature difference threshold of first setting is preset numerical value, for reflecting real-time room temperature and room temperature target
The size of the difference of value, the threshold value can be preset in a control program default temperature value when factory, be also possible to by sky
A temperature value of device user sets itself is adjusted, can be modified by authorization.
For the real-time indoor temperature difference, it will be appreciated by those skilled in the art that if air conditioner runs refrigeration mode, real-time room
Interior temperature is generally greater than room temperature target value, then the indoor temperature difference is that real-time room temperature subtracts room temperature target value in real time
Difference.If air conditioner runs heating mode, room temperature target value is generally greater than real-time room temperature, then the real-time indoor temperature difference
It is the difference that room temperature target value subtracts real-time room temperature.After getting the real-time temperature difference, the indoor temperature difference is set with first
Threshold value comparison size executes different compressor controls according to comparison result and handles.
Step 102: whether the indoor temperature difference sets indoor temperature difference threshold less than first in real time for judgement.If so, executing step 103
Control；Otherwise, the control of step 104 is executed.
Step 103: if step 102 determines that the indoor temperature difference sets indoor temperature difference threshold less than first in real time, and control is pressed
The winding of contracting machine is star-like connection mode.
If the interior temperature difference sets indoor temperature difference threshold less than first in real time, the indoor temperature difference is smaller in real time at this time, real-time room
Interior temperature is close to room temperature target value.In this case, compressor will generally be run with low frequency.Therefore, control compression in advance

Step 104: if step 102 determines that the indoor temperature difference sets indoor temperature difference threshold not less than first in real time, will control
The winding of compressor is triangle connection type.
If the interior temperature difference sets indoor temperature difference threshold not less than first in real time, the indoor temperature difference is larger in real time at this time, in real time
Room temperature and room temperature target value difference are big.In this case, compressor will generally be run with high-frequency.Therefore, it controls in advance
The winding of compressor processed is triangle connection type, can more preferably be pressed under subsequent compression machine high-frequency operating status
Contracting machine operational efficiency.
Control compressor is star-like connection mode or is triangle connection type, can be realized using the prior art,
The embodiment is not construed as limiting this.
Also, the winding switching control process that above steps is constituted, which recycles, to be executed.That is, in control compressor with star
In connection type or the triangle connection type course of work, still constantly execute step 101 obtain the indoor temperature difference in real time and after
Which kind of winding connection is continuous multilevel iudge process, meet, then controls compressor winding and be switched to the connection type.
Using the cooler compressor control method of the embodiment, using the indoor temperature difference as switching compressor winding connection side
The condition of formula, since the indoor temperature difference directly reflects the comfort of indoor environment, with indoor temperature difference control winding connection type
Switching is able to achieve compared with the prior art is using the switching of compressor frequency control connection type based on environmental amenity degree intelligence
It can control compressor, reach taking into account for amenity and compressor operational efficiency；Also, although the indoor temperature difference is reflection compression
The indirect factor of operational efficiency in machine whole service frequency range, but adjust the compressor frequency direct ginseng to be regulated and controled
Number, thus, with the switching of indoor temperature difference control winding connection type, can be realized the anticipation to compressor winding connection and
It controls in advance, control reliability is higher；And the indoor temperature difference will not be mutated, because without caused by compressor because continually switching winding
The comfort of indoor environment is reduced brought by connection type, reduces the generation of the problems such as compressor service life, improves sky
Adjust device overall performance.

209；Otherwise, step 206 is executed.
Step 206: if step 205 determines that the indoor temperature difference sets indoor temperature difference threshold not less than first in real time, then comparing
The size that the interior temperature difference sets indoor temperature difference threshold with second in real time judges whether the indoor temperature difference is greater than the second setting interior in real time
Temperature difference threshold.The control of step 207 or step 208 is executed according to judging result.
Wherein, second indoor temperature difference threshold is set greater than the first indoor temperature difference threshold of setting and preset numerical value, reflection
The size of the difference of real-time room temperature and room temperature target value.Likewise, the indoor temperature difference threshold of the second setting can be factory
When preset in a control program a default temperature value, be also possible to a temperature value by air conditioner user's sets itself,
It can be modified by authorization.
Step 207: if it is determined that the interior temperature difference sets indoor temperature difference threshold not less than first and sets no more than second in real time
Fixed interior temperature difference threshold shows that the indoor temperature difference is of moderate size in real time, is triangle connection type by the winding for controlling compressor, with
Improve compressor operational efficiency.Meanwhile compressor operating frequency will also be adjusted, specifically based on the indoor temperature difference in real time
The running frequency of compressor is adjusted, realizes the technical effect that the adjustment of transducer air conditioning temperature is accurate, low energy consumption.And it is based on real-time room

Determine real-time frequency, control compressor is run with real-time frequency.PID arithmetic or increment type PID operation control are executed according to deviation
Specific method and realize process can refer to the prior art.
Step 208: if it is determined that the interior temperature difference is greater than the indoor temperature difference threshold of the second setting in real time, showing the indoor temperature difference in real time
It is larger, it is triangle connection type by the winding of compressor is controlled, to improve compressor operational efficiency.Meanwhile compressor is transported
Line frequency will also adjust, and control compressor specifically to fix running frequency operation, and the fixation running frequency is general
For higher frequency, reach in quickly-conditioning indoor temperature to the technical effect of comfort temperature.
Step 209: if step 205 determines that the indoor temperature difference sets indoor temperature difference threshold less than first in real time, and control is pressed
The winding of contracting machine is star-like connection mode.
If the interior temperature difference sets indoor temperature difference threshold less than first in real time, the indoor temperature difference is smaller in real time at this time, real-time room
Interior temperature is close to room temperature target value.In this case, compressor will generally be run with low frequency.Therefore, control compression in advance
