As shown in Figure 1, the method that the embodiment realizes compressor of air conditioner control includes the following steps that the winding to be formed switches
Control process:
Step 101: the temperature difference between real-time body's comfort level and comfort level target value is calculated, real-time comfort level difference is obtained, it will
Real-time comfort level difference is made comparisons with the first setting comfort level difference threshold.
Wherein, real-time body's comfort level refers to is obtained in air conditioner booting operational process, according to setting using frequency in real time
Air conditioner locating for human body in room comfort level.Specifically, obtaining real-time body's comfort level using following methods:
Acquire air-conditioned room in user human body in real time clothing shell temperature Ts.Human body in real time clothing shell temperature Ts can pass through

The size for comparing real-time comfort level difference with the second setting comfort level difference threshold, judges whether real-time comfort level difference is greater than the
Two setting comfort level difference thresholds.The control of step 207 or step 208 is executed according to judging result.
Wherein, the second setting comfort level difference threshold is greater than the first setting comfort level difference threshold and preset numerical value,
Reflect the size of the difference of real-time body's comfort level and comfort level target value.Likewise, the second setting comfort level difference threshold can be with
Preset in a control program a default value, is also possible to a value by air conditioner user's sets itself, energy when being factory
It is enough to be modified by authorization.
Step 207: if it is determined that comfort level difference is not less than the first setting comfort level difference threshold and no more than the in real time
Two setting comfort level difference thresholds, show that real-time comfort level size of the difference is moderate, are triangle company by the winding for controlling compressor
Mode is connect, to improve compressor operational efficiency.Meanwhile compressor operating frequency will also be adjusted, specifically based on real
When room temperature and room temperature target value between the real-time temperature difference adjustment compressor running frequency, realize transducer air conditioning temperature

, the indoor target temperature achieved of expectation.And the running frequency based on real-time temperature difference adjustment compressor, it is preferably based in real time
The temperature difference carries out PID arithmetic or increment type PID operation, determines real-time frequency, and control compressor is run with real-time frequency.According to deviation
It executes the specific method of PID arithmetic or increment type PID operation control and realizes that process can refer to the prior art.
Step 208: if it is determined that comfort level difference is greater than the second setting comfort level difference threshold in real time, showing comfortable in real time
Degree difference is larger, is triangle connection type by the winding of compressor is controlled, to improve compressor operational efficiency.Meanwhile to pressure
Contracting machine running frequency will also adjust, and control compressor specifically to fix running frequency operation, and fixation operation frequency
Rate is generally higher frequency, reaches the technical effect for quickly adjusting human comfort to level of comfort.
Step 209: if step 205 determines that real-time comfort level difference less than the first setting comfort level difference threshold, will be controlled
The winding of compressor processed is star-like connection mode.
If real-time comfort level difference is less than the first setting comfort level difference threshold, real-time comfort level difference is smaller at this time,
Real-time body's comfort level is close to comfort level target value.In this case, compressor will generally be run with low frequency.Therefore, it controls in advance
The winding of compressor processed is star-like connection mode, can more preferably be compressed under subsequent compression machine low frequency operating status
