Fig. 3 is the structural representation of the control device of air-conditioner according to an embodiment of the invention.
Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Typically, do not have flow larger due to cold, refrigerating/heating efficiency is relatively higher, therefore, at coolant system operationally, in order to meet refrigerating/heating demand, refrigeration system is in the past pursued refrigerating/heating fast and is often made every effort to make cold medium flux reach capacity fast, so can drive compressor operation with very high speed, thus brings the noise of higher refrigerant flowing generation, cold medium flux is larger, and the flow noise relatively produced is higher.And at some special occasions, such as sleep pattern, noise will be far longer than the impact of temperature for the impact of user.So, make every effort to the operation noise reducing coolant system.Therefore, embodiments of the invention propose a kind of control method of air-conditioner, the control device of air-conditioner and air-conditioner.
Below with reference to the accompanying drawings the control method of the air-conditioner according to the embodiment of the present invention, the control device of air-conditioner and air-conditioner are described.
Fig. 1 is the flow chart of the control method of air-conditioner according to an embodiment of the invention.
Wherein, this air-conditioner comprises the coolant system being connected with indoor and outdoor heat exchanger, the throttling arrangement of junction chamber internal-external heat exchanger device, and drives the frequency-changeable compressor of refrigerant running.Particularly, as shown in Figure 1, the control method of this air-conditioner, comprises the following steps:
S101, when air-conditioner is in stillness mode, the frequency-changeable compressor controlling air-conditioner with first frequency starts.
In an embodiment of the present invention, stillness mode is by the operational mode reduced for the purpose of air-conditioner operation noise, can be applicable to some special occasions, such as, and the situation of explaining and publicising of sleep quality, meeting room or other situations needing reduction noise to bother user.
Particularly, at above-mentioned special occasions, the operational mode of air-conditioner is set to stillness mode by the human-computer interaction interface that user provides by air-conditioner, the remote controller of air-conditioner or the mobile terminal communicated with air-conditioner.
In an embodiment of the present invention, the frequency values near the low-limit frequency that the frequency-changeable compressor that first frequency can be air-conditioner can run.First frequency presets according to the frequency of the sustainable low-frequency operation of the frequency-changeable compressor used in air-conditioner.Such as, can be 4-10 hertz, this frequency range is the frequency of the sustainable low-frequency operation of the current frequency-changeable compressor that can realize.Should be appreciated that improving constantly along with technology, the frequency of the sustainable low-frequency operation of frequency-changeable compressor can become lower, and first frequency can correspondingly adjust according to the frequency of the sustainable low-frequency operation of frequency-changeable compressor.
S102, after the first Preset Time, controls frequency-changeable compressor with the first scheduled rate and carries out raising frequency.
Particularly, in an embodiment of the present invention, when frequency-changeable compressor low frequency (first frequency) runs, the displacement of compressor can be fewer, like this after operation a period of time, the pressure of high-pressure side and low-pressure side can progressively tend to balance, and namely the pressure differential of high-pressure side and low-pressure side reaches preset pressure difference, cold medium flux tends towards stability, and now can control frequency-changeable compressor and carry out raising frequency.Wherein, preset pressure difference for compressor run with first frequency time, when the pressure of high-pressure side and low-pressure side tends to balance, the pressure differential of high-pressure side and low-pressure side.
Therefore, in one embodiment of the invention, the first Preset Time is that after controlling the frequency-changeable compressor startup of air-conditioner with first frequency, the high-pressure side of frequency-changeable compressor and the pressure differential of low-pressure side reach the time needed for preset pressure difference.
Wherein, the first scheduled rate is the speed being less than scheduled rate threshold value.In a preferred embodiment of the invention, scheduled rate threshold value can be 0.3 hertz/sec, and certainly, scheduled rate threshold value also can be 0.8 hertz/sec, 0.1 hertz/sec etc.
In an embodiment of the present invention, frequency-changeable compressor is with a lower speed raising frequency, thus the gas transmission velocity variations of compressor is comparatively slow, and the heat exchange state like this for evaporimeter and condenser is just with low uncertainty.For condenser, when the cold media gas amount entered increases, the flow velocity of refrigerant can be improved, the gas-liquid skewness in condenser can be caused simultaneously, and when gas transmission velocity variations is slower, can reduce the flow velocity of refrigerant, thus the change of this gas-liquid distribution is also slowed down, thus the refrigerant flow noise not easily produced in heat exchanger, mechanicalness noise also can reduce.
S103, judges whether cold medium flux reaches the first preset flow.
Along with the raising of compressor operating frequency, refrigerant flow rate improves, and correspondingly, cold medium flux strengthens, and the refrigerant flow noise sent is larger.When cold medium flux promotes rapidly, noise will be very large.Therefore, by increasing the running frequency of compressor gradually, making cold medium flux reach the first preset flow lentamente, while reducing noise, meeting the refrigerating/heating efficiency of user.
S104, if cold medium flux reaches the first preset flow, then controls described frequency-changeable compressor and stops raising frequency.Namely by increasing the running frequency of compressor gradually, till making cold medium flux reach the first preset flow lentamente.The large noise avoiding cold medium flux to promote rapidly causing, avoids affecting user.
In an embodiment of the present invention, when the ongoing frequency of frequency-changeable compressor reaches the frequency that in stillness mode, noise setting value is corresponding, if continue to control frequency-changeable compressor raising frequency, then the frequency of frequency-changeable compressor can be made to rise to resonant frequency, now can resonate, thus cause noise to increase.Therefore, when the ongoing frequency of frequency-changeable compressor reaches the frequency that in stillness mode, noise setting value is corresponding, need to control frequency-changeable compressor and stop raising frequency, increase noise to avoid resonance occurs.
In one embodiment of the invention, the method also comprises: while carrying out raising frequency with the first scheduled rate control frequency-changeable compressor, the rotating speed controlling outdoor fan improves gradually.That is, when cold medium flux is less, outdoor fan can run, because cold medium flux is less with relatively low rotating speed, just can meet the demands compared with the outdoor fan of low cruise, meanwhile, rotating speed is lower, and noise is less, therefore, noise can be reduced further, promote Consumer's Experience.
The control method of the air-conditioner of the embodiment of the present invention, when air-conditioner is in stillness mode, control frequency-changeable compressor with lower first frequency to start, and after the first Preset Time, control frequency-changeable compressor with the first lower scheduled rate and carry out raising frequency, the refrigerant stream required for low-frequency start is very little, thus reduces the noise of refrigerant flowing, and the slow raising frequency of frequency-changeable compressor can make the velocity variations of refrigerant stream slow down, thus the noise that the speed acute variation avoiding refrigerant stream is brought.In addition, when the frequency of frequency-changeable compressor reaches the frequency that in stillness mode, noise setting value is corresponding, raising frequency is stopped, when the frequency of frequency-changeable compressor can be avoided to reach resonant frequency and other devices or the refrigerant stream noise that occurs to resonate and produce.Thus, the method can effectively reduce amount of flow and the impulsive force of refrigerant, thus reduces refrigerant sound and mechanicalness noise, avoids to cause user to bother, and improves the experience of user.
Fig. 2 is the flow chart of the control method of air-conditioner in accordance with another embodiment of the present invention.
As shown in Figure 2, the control method of this air-conditioner, comprises the following steps:
S201, when air-conditioner is in stillness mode, the frequency-changeable compressor controlling air-conditioner with first frequency starts.
In an embodiment of the present invention, stillness mode is by the operational mode reduced for the purpose of air-conditioner operation noise, can be applicable to some special occasions, such as, and the situation of explaining and publicising of sleep quality, meeting room or other situations needing reduction noise to bother user.
Particularly, at above-mentioned special occasions, the operational mode of air-conditioner is set to stillness mode by the human-computer interaction interface that user provides by air-conditioner, the remote controller of air-conditioner or the mobile terminal communicated with air-conditioner.
In an embodiment of the present invention, the frequency values near the low-limit frequency that the frequency-changeable compressor that first frequency can be air-conditioner can run.First frequency presets according to the frequency of the sustainable low-frequency operation of the frequency-changeable compressor used in air-conditioner.Such as, can be 4-10 hertz, this frequency range is the frequency of the sustainable low-frequency operation of the current frequency-changeable compressor that can realize.Should be appreciated that improving constantly along with technology, the frequency of the sustainable low-frequency operation of frequency-changeable compressor can become lower, and first frequency can correspondingly adjust according to the frequency of the sustainable low-frequency operation of frequency-changeable compressor.
S202, after the first Preset Time, controls frequency-changeable compressor with the first scheduled rate and carries out raising frequency.
Particularly, in an embodiment of the present invention, when frequency-changeable compressor low frequency (first frequency) runs, the displacement of compressor can be fewer, like this after operation a period of time, the pressure of high-pressure side and low-pressure side can progressively tend to balance, and namely the pressure differential of high-pressure side and low-pressure side reaches preset pressure difference, now can control frequency-changeable compressor and carry out raising frequency.
Therefore, in one embodiment of the invention, the first Preset Time is that after controlling the frequency-changeable compressor startup of air-conditioner with first frequency, the high-pressure side of frequency-changeable compressor and the pressure differential of low-pressure side reach the time needed for preset pressure difference.
Wherein, the first scheduled rate is the speed being less than scheduled rate threshold value.In a preferred embodiment of the invention, scheduled rate threshold value can be 0.3 hertz/sec, and certainly, scheduled rate threshold value also can be 0.8 hertz/sec, 0.1 hertz/sec etc.
In an embodiment of the present invention, frequency-changeable compressor is with a lower speed raising frequency, thus the gas transmission velocity variations of compressor is comparatively slow, and the heat exchange state like this for evaporimeter and condenser is just with low uncertainty.For condenser, when the cold media gas amount entered increases, the flow velocity of refrigerant can be improved, the gas-liquid skewness in condenser can be caused simultaneously, and when gas transmission velocity variations is slower, can reduce the flow velocity of refrigerant, thus the change of this gas-liquid distribution is also slowed down, thus the refrigerant flow noise not easily produced in heat exchanger, mechanicalness noise also can reduce.
S203, judges whether the ongoing frequency of frequency-changeable compressor reaches the frequency that in stillness mode, noise setting value is corresponding.
In an embodiment of the present invention, the frequency that in stillness mode, noise setting value is corresponding can be one or more, can be respectively the resonant frequency of refrigerant, compressor or other devices etc.For example, if resonant frequency is 3 hertz, the frequency that in stillness mode, noise setting value is corresponding can be 3 hertz.
S204, if the ongoing frequency of frequency-changeable compressor reaches the frequency that in stillness mode, noise setting value is corresponding, then controls frequency-changeable compressor and stops raising frequency.
In an embodiment of the present invention, when the ongoing frequency of frequency-changeable compressor reaches the frequency that in stillness mode, noise setting value is corresponding, if continue to control frequency-changeable compressor raising frequency, then the frequency of frequency-changeable compressor can be made to rise to resonant frequency, now can resonate, thus cause noise to increase.Therefore, when the ongoing frequency of frequency-changeable compressor reaches the frequency that in stillness mode, noise setting value is corresponding, need to control frequency-changeable compressor and stop raising frequency, increase noise to avoid resonance occurs.
S205, the frequency keeping frequency-changeable compressor is the frequency that in stillness mode, noise setting value is corresponding, and after the second Preset Time, the frequency redirect controlling frequency-changeable compressor is second frequency, wherein, second frequency is higher than frequency corresponding to noise setting value in stillness mode.
In one embodiment of the invention, second frequency can be determined according to the raising frequency cycle, for example, can be two raising frequency cycles.Such as, if the raising frequency cycle of frequency-changeable compressor is 1 second, i.e. the frequency of frequency-changeable compressor lifting per second 0.3 hertz, then the second Preset Time is 2 seconds.Second frequency is on the basis of ongoing frequency, the frequency be increased to through the second Preset Time and according to the first scheduled rate.For example, if ongoing frequency is 2.8 hertz, the first scheduled rate is 0.3 hertz/sec, and the second Preset Time is 2 seconds, then second frequency is 3.4 hertz.
Thus, after maintenance ongoing frequency waits for the second Preset Time, the frequency controlling frequency-changeable compressor jumps to second frequency by the frequency that noise setting value in stillness mode is corresponding, can skip resonant frequency, thus avoids the noise produced because there is resonance.
S206, controls frequency-changeable compressor and continue raising frequency with the first scheduled rate by second frequency.
The control method of the air-conditioner of the embodiment of the present invention, when the ongoing frequency of frequency-changeable compressor reaches the frequency that in stillness mode, noise setting value is corresponding, stop raising frequency, and after continuing the second Preset Time, the frequency redirect controlling frequency-changeable compressor is that second frequency continues raising frequency, can skip resonant frequency, thus avoids the noise produced because there is resonance, further reduce noise bothering user, promote Consumer's Experience.
In order to be reduced in the operation noise of coolant system in process that compressor frequency switches, in an embodiment of the present invention, described air-conditioner is provided with high side pressure detecting unit, low-pressure lateral pressure detecting unit, is respectively used to the pressure reading relevant position.In the process of raising frequency, can divide equally to obtain multiple raising frequency force value to goal pressure difference according to raising frequency situation, after each raising frequency, if detect that the pressure differential of described high-pressure side and described low-pressure side reaches raising frequency value, then continue raising frequency.Wherein, the on high-tension side pressure of coolant system and the pressure differential of coolant system initial pressure when goal pressure difference is for reaching the temperature of user's setting.
Particularly, suppose that initial pressure is P0, when current working is issued to the design temperature of user, the on high-tension side pressure of coolant system is P1, then coolant system needs to boost to P1 pressure from P0 pressure, and goal pressure difference is P1-P0.For convenience of description, for example, goal pressure difference can be divided into 10 ladders, obtain each pressure △ P=(P1-P0)/10 promoted, after the compressor start of then coolant system, when system stability is to P0+ △ P, raising frequency operation can be carried out again, so analogize, until on high-tension side pressure is P1.Due to the instability of refrigerant pressure can be extra generation noise, particularly the pipeline of condenser is longer, and connect comparatively complicated, particularly can there is a small amount of uncondensable gas in some condensers, when raising frequency is very fast, a large amount of gaseous working medium enter condenser and cannot order, effective condensation, the movement disorder in condenser will be caused, thus cause vibrations and noise.When after pressure balance, then improve compressor frequency, the capacity of steady raising compressor, effectively can reduce or eliminate the noise produced in the process switched in start-up course or compressor frequency.
In an embodiment of the present invention, for the control procedure stopping frequency-changeable compressor, identical with the principle starting frequency-changeable compressor.Particularly, when receiving the halt instruction controlling frequency-changeable compressor, controlling frequency-changeable compressor with the second scheduled rate and carrying out frequency reducing; Judge that described cold medium flux drops to the second preset flow, wherein, described second preset flow is less than described first preset flow;
If described cold medium flux drops to the second preset flow, then control described frequency-changeable compressor and stop frequency reducing.Wherein, the second scheduled rate can be identical with the first scheduled rate, also can be different from the first scheduled rate, can be 0.3 hertz/sec, 0.8 hertz/sec, 0.1 hertz/sec etc.
In one embodiment of the invention, after control frequency-changeable compressor stops frequency reducing, also comprise: the frequency keeping frequency-changeable compressor is the frequency that in stillness mode, noise setting value is corresponding, and after the 3rd Preset Time, the frequency redirect controlling frequency-changeable compressor is the 3rd frequency, wherein, the 3rd frequency is lower than frequency corresponding to noise setting value in stillness mode; Control frequency-changeable compressor and continue frequency reducing with the second scheduled rate from the 3rd frequency; When the frequency of frequency-changeable compressor is down to first frequency, stop frequency reducing, and after the first Preset Time, stop frequency-changeable compressor.Wherein, the 3rd frequency can be determined according to the frequency reducing cycle, for example, can be two frequency reducing cycles.Such as, if the raising frequency cycle of frequency-changeable compressor is 1 second, i.e. the frequency of frequency-changeable compressor reduction per second 0.3 hertz, then the 3rd Preset Time is 2 seconds.3rd frequency is on the basis of ongoing frequency, the frequency be reduced to through the 3rd Preset Time and according to the second scheduled rate.For example, if ongoing frequency is 3.2 hertz, the second scheduled rate is 0.3 hertz/sec, and the 3rd Preset Time is 2 seconds, then the 3rd frequency is 2.6 hertz.
Thus, after maintenance ongoing frequency waits for the 3rd Preset Time, the frequency controlling frequency-changeable compressor jumps to the 3rd frequency by the frequency that noise setting value in stillness mode is corresponding, can skip resonant frequency, thus avoids the noise stopping producing because there is resonance in frequency-changeable compressor process.
The control method of the air-conditioner of the embodiment of the present invention, when air-conditioner is in stillness mode, control frequency-changeable compressor with lower first frequency to start, and after the first Preset Time, control frequency-changeable compressor with the first lower scheduled rate and carry out raising frequency, the refrigerant stream required for low-frequency start is very little, thus reduces the noise of the large generation of cold medium flux, and the slow raising frequency of frequency-changeable compressor can make the velocity variations of refrigerant stream slow down, thus avoid the noise that cold medium flux acute variation brings.Reduce refrigerant sound and mechanicalness noise, avoid to cause user and bother, improve the experience of user.
