Specific embodiment
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 that the present invention is based on method one of interior machine blast velocity control cooler compressor implementations
The flow chart of example is specifically the compressor control for taking into account one embodiment of amenity and compressor operational efficiency
Method flow diagram.
As shown in Figure 1, the method that the embodiment realizes cooler compressor control includes the following steps that the winding to be formed is cut
Change control process:
Step 101: determining the real-time interior machine wind speed of air conditioner room unit, interior machine wind speed and the first wind speed setting threshold value will make in real time
Compare.
Machine wind speed in real time is the room that constantly obtains and update according to setting sample frequency after air conditioner booting operation
The speed of inner blower.The speed can easily be obtained by indoor machine controller.First wind speed setting threshold value is preset known
Air speed value, for reflecting the size of indoor unit wind speed.The threshold value can be preset in a control program default when factory
Value, is also possible to a value by air conditioner user's sets itself, can be modified by authorization.Getting machine wind in real time
After speed, with the first wind speed setting threshold value comparison size, different compressor controls is executed according to comparison result and is handled.
Step 102: whether machine wind speed is less than the first wind speed setting threshold value in judgement in real time.If so, executing the control of step 103
System；Otherwise, the control of step 104 is executed.
Step 103: if step 102 determines that machine wind speed will control compressor less than the first wind speed setting threshold value in real time
Winding be star-like connection mode.
If machine wind speed is less than the first wind speed setting threshold value in real time, interior machine wind speed is smaller in real time at this time.Wind speed is small, a side
Face shows that indoor occupant is small to the air-out volume demand after air-conditioning heat exchange, namely the demand to indoor temperature control is small, on the other hand
The air quantity for participating in indoor heat exchanger heat exchange is also small.In this case, to avoid outlet air due to temperature is not suitable for blowing on human body
Cause discomfort, cause waste energy consumption also for avoiding heat exchanger heat exchange property superfluous, compressor will generally be run with low frequency.
Therefore, the winding for controlling compressor in advance is star-like connection mode, can obtain under subsequent compression machine low frequency operating status
Obtain more preferably compressor operational efficiency.
Step 104: if step 102 determines that machine wind speed compresses control not less than the first wind speed setting threshold value in real time
The winding of machine is triangle connection type.
If machine wind speed is not less than the first wind speed setting threshold value in real time, interior machine wind speed is larger in real time at this time.Wind speed is big, and one
Aspect shows that indoor occupant is big to the air-out volume demand after air-conditioning heat exchange, namely the demand to indoor temperature control is big, another party
The air quantity that face participates in indoor heat exchanger heat exchange is also big.In this case, being raising personnel comfort, and also to increase interior
The heat exchange property of heat exchanger meets Wind Volume heat exchange demand, and compressor will generally run with high-frequency.Therefore, control is pressed in advance
The winding of contracting machine is triangle connection type, can obtain more preferably compressor under subsequent compression machine high-frequency operating status
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 in real time in machine wind speed and after
Which kind of winding connection is continuous multilevel iudge process, meet, then controls compressor winding and be switched to the connection type.
Moreover, being that triangle connection type or star connect in the winding of control compressor during winding switching control
While connecing mode, also based on the real-time indoor temperature difference adjustment compressor between real-time room temperature and room temperature target value
Running frequency realizes the technical effect that the adjustment of transducer air conditioning temperature is accurate, low energy consumption.Real-time room temperature refers to according to certain
The air-conditioning that constantly obtains of sample frequency locating for room indoor environment temperature.It for example, can be by the temperature that is arranged on air-conditioning
Detection device is spent to obtain.Room temperature target value is the indoor temperature value that can reach of expectation, be can be preset silent
Recognize value, or the value for user's sets itself.And the running frequency based on real-time indoor temperature difference adjustment compressor, it is preferably based on
The interior temperature difference carries out PID arithmetic or increment type PID operation in real time, determines real-time frequency, and control compressor is run with real-time frequency.
The specific method of PID arithmetic or increment type PID operation control is executed according to deviation and realizes that process can refer to the prior art.
Using the cooler compressor control method of the embodiment, compressed the real-time interior machine wind speed of indoor unit as switching
The condition of machine winding connection under different interior machine wind speed, needs the frequency to air-conditioning to realize the comfort of personnel
Make different adjustment, that is, the different control strategies for realizing indoor environment comfort are corresponding in difference under machine wind speed, because
This, interior machine wind speed reflects the comfort of indoor environment indirectly, with the prior art using compressor frequency control connection type
Switching is compared, and has both been able to achieve and has been controlled compressor based on ambient intelligence, and taking into account for amenity and compressor operational efficiency is reached；
Also, although interior machine wind speed is to reflect the indirect factor of compressor operational efficiency, but adjust compressor frequency and make room
It is interior it is comfortable with reference to direct parameter, thus, within machine blast velocity control winding connection switching, can be realized to compression
It the anticipation of machine winding connection and controls, is swift in response in advance, control reliability is higher.
Fig. 2 is referred to, which show that the present invention is based on another realities of the method for interior machine blast velocity control cooler compressor
The flow chart of example is applied, specifically, and takes into account the compressor of one embodiment of amenity and compressor operational efficiency
Control method flow chart.
As shown in Fig. 2, the method that the embodiment realizes cooler compressor control includes the following steps the process to be formed:
Step 201: air conditioner booting operation.
Step 202: judging whether air conditioner operation meets setting service condition, and step 203 is executed according to judging result
Or step 204.
Setting service condition be for judge Air conditioners running mode if appropriate for execute winding switching control process condition,
The running frequency that runing time including but not limited to after air conditioner booting reaches after setting runing time or booting reaches and sets
Determine running frequency.
Step 203: if step 202 determine operation of air conditioner do not meet setting service condition also, by control compressor around
Group is triangle connection type.
Generally, air conditioner can reach setting service condition with faster speed, also, after air conditioner booting, empty
Adjusting device is typically all high frequency operation, rapidly reaches higher frequency.In light of this situation, in this embodiment, by triangle
Connection type as booting after compressor winding initial connection mode, avoid the operation of air conditioner initial stage continually switch around
Group connection type.
Meanwhile in the control stage, compressor operating frequency is not construed as limiting, can be run for the frequency of putting of non-frequency limit,
It is fixed and for higher frequency to be also possible to operation one, realizes the quick adjusting of room temperature.
Step 204: if step 202 determines air conditioner, operation meets setting service condition, will execute and be based in real time
The winding connection of machine wind speed controls.
Specifically, it is the real-time interior machine wind speed of determining air conditioner room unit, wind will be set by interior machine wind speed and first in real time
Fast threshold value is made comparisons.The step more specifically realizes corresponding description of the process refering to fig. 1 in embodiment in corresponding steps.
Step 205: whether machine wind speed is less than the first wind speed setting threshold value in judgement in real time.If so, executing step 209；It is no
Then, step 206 is executed.
Step 206: if step 205 determines that machine wind speed is real-time not less than the first wind speed setting threshold value, then relatively in real time
The size of interior machine wind speed and the second wind speed setting threshold value judges whether machine wind speed is greater than the second wind speed setting threshold value in real time.Root
It is judged that result executes the control of step 207 or step 208.
Wherein, the second wind speed setting threshold value is greater than the first wind speed setting threshold value and preset numerical value, reflects indoor machine wind
The size of speed.Likewise, the second wind speed setting threshold value can be preset in a control program default value when factory, it can also
To be a value by air conditioner user's sets itself, can be modified by authorization.
Step 207: if it is determined that machine wind speed is not less than the first wind speed setting threshold value and no more than the second setting wind in real time
Fast threshold value shows that machine wind speed is of moderate size in real time, is triangle connection type by the winding for controlling compressor, to improve compression
Machine operational efficiency.Meanwhile compressor operating frequency will also be adjusted, specifically it is based on real-time room temperature and Indoor Temperature
The running frequency for spending the real-time indoor temperature difference adjustment compressor between target value, realizes that transducer air conditioning temperature adjusts accurate, energy
Consume low technical effect.The detailed process of compressor operating frequency is adjusted referring to the phase of Fig. 1 embodiment based on the real-time indoor temperature difference
It should describe.
Step 208: if it is determined that in real time in machine wind speed be greater than the second wind speed setting threshold value, show in real time in machine wind speed compared with
It greatly, is triangle connection type by the winding of compressor is controlled, to improve compressor operational efficiency.Meanwhile compressor is run
Frequency will also adjust, and control compressor with the frequency operation not less than setting high frequency value.Specifically, it obtains and is based on first
The running frequency that the interior temperature difference determines in real time, and make comparisons with setting high frequency value, if the operation determined based on the real-time indoor temperature difference
Frequency is run no more than setting high frequency value, control compressor using setting high frequency value as actual motion frequency.Certainly, if be based on
The running frequency that the interior temperature difference determines in real time is greater than setting high frequency value, then the running frequency control to be determined based on the real-time indoor temperature difference
Compressor processed operation, thus, reach in quickly-conditioning indoor temperature to the technical effect of level of comfort.
Step 209: if step 205 determines that machine wind speed will control compressor less than the first wind speed setting threshold value in real time
Winding be star-like connection mode.
If machine wind speed is less than the first wind speed setting threshold value in real time, interior machine wind speed is smaller in real time at this time.Wind speed is small, a side
Face shows that indoor occupant is small to the air-out volume demand after air-conditioning heat exchange, namely the demand to indoor temperature control is small, on the other hand
The air quantity for participating in indoor heat exchanger heat exchange is also small.In this case, to avoid outlet air due to temperature is not suitable for blowing on human body
Cause discomfort, cause waste energy consumption also for avoiding heat exchanger heat exchange property superfluous, compressor will generally be run with low frequency.
Therefore, the winding for controlling compressor in advance is star-like connection mode, can obtain under subsequent compression machine low frequency operating status
Obtain more preferably compressor operational efficiency.Meanwhile compressor operating frequency will also be adjusted, specifically it is also based on real-time room
The running frequency of real-time indoor temperature difference adjustment compressor between interior temperature and room temperature target value, realizes transducer air conditioning temperature
The technical effect that degree adjustment is accurate, low energy consumption.More specific frequency adjusting method referring to Fig. 1 embodiment corresponding description.
It is triangle in the winding of control compressor during winding switching control in some other preferred embodiment
While shape connection type, the running frequency of control compressor is not less than setting critical frequency.Wherein, setting critical frequency is
Known frequency values, generally the compressor frequency values that operational efficiency is transferred under two kinds of winding connections, Ke Yigen
It is determined according to compressor operational efficiency curve.Minimum fortune is made by the running frequency to compressor under triangle connection type as a result,
The restriction of line frequency, so that compressor maintains higher operational efficiency under the winding connection.
Likewise, during winding switching control, while the winding for controlling compressor is star-like connection mode, control
The running frequency of compressor processed is less than setting critical frequency.Pass through the running frequency to compressor under star-like connection mode as a result,
Make the restriction of maximum frequency of operation, so that compressor also maintains higher operational efficiency under the winding connection.
Cooler compressor is controlled using the method for the embodiment, had both been able to achieve based on environmental amenity degree intelligent control pressure
Contracting machine reaches taking into account for amenity and compressor operational efficiency, not will cause compressor also because continually switching winding connects
