Accompanying drawing explanation
Above-mentioned and/or additional aspect of the present invention and advantage will become obvious and easy understand from accompanying drawing below combining to the description of embodiment, wherein:
Fig. 1 is the flow chart of the control method of air-conditioner according to an embodiment of the invention; And
Fig. 2 is the structured flowchart of the control system of air-conditioner in accordance with another embodiment of the present 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.
Because air-conditioner is transformed into ventilation from refrigeration, or when compressor frequency is low especially, the structural member of air conditioner room unit affects by air-supply, can more close to indoor temperature, if at this moment promote the running frequency of compressor or start compressor, when fast-refrigerating heats, indoor heat exchanger temperature can be made sharply to decline, thus reduction wind pushing temperature, thus reduce the temperature of air channel peripheral parts, but the temperature of peripheral components also can be higher, so form cold and hot expansion sound, such as dislocation produces the noise of " click, click ".
Below with reference to the accompanying drawings the control method of the air-conditioner according to the embodiment of the present invention, the control system 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 temperature sensor on indoor set, compressor, expansion valve, indoor heat converter and heat exchanger disposed in the interior, and indoor set is comprised at least one parts and realized by the form of clamping and other parts fixing.As shown in Figure 1, the control method of this air-conditioner, comprises the following steps:
S101, when air-conditioner enters quiet operational mode, detects the duty of compressor and the Current Temperatures of indoor heat exchanger.
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.
S102, when the duty of compressor changes, the temperature of control room inside heat exchanger is less than predetermined threshold value with the speed of the variations in temperature making indoor heat exchanger, until reach target temperature.Predetermined threshold value is such as but is not limited to 2 degrees/min.
Wherein, the duty of compressor changes and such as comprises: compressor start, shutdown or mode of operation switching etc.Mode of operation switching includes but not limited to: the switching between refrigeration mode, heating mode and air vent mode etc.
For compressor start, then under stillness mode, when compressor start, start with first frequency, wherein, 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.
In an embodiment of the present invention, frequency-changeable compressor with a lower speed raising frequency or the pressure changing expansion valve, thus can make the rate of temperature change of indoor heat exchanger slower.Then, according to target temperature, adjust the running frequency of compressor and/or the pressure of expansion valve gradually, thus make the speed of the variations in temperature of indoor heat converter be less than predetermined threshold value.Such as: according to Current Temperatures and the target temperature of indoor heat converter, the temperature of control room inside heat exchanger is changed with relative speed slowly by Current Temperatures, until reach target temperature, like this, sufficient heat transfer/biography cool time can be had between parts (such as air channel, indoor heat exchanger and and the parts that close on of air channel, indoor heat exchanger) for air-conditioner, thus effectively can reduce even elimination expansion noise (noise of " click; click " that send when such as air-conditioner starts), avoid noise annoying users, promote Consumer's Experience.
In one embodiment of the invention, the temperature of control room inside heat exchanger is less than predetermined threshold value with the speed of the variations in temperature making indoor heat exchanger and specifically comprises:
1, current environmental temperature is obtained, and according to current environmental temperature determination first object temperature.Specifically comprise: current environmental temperature is increased or deducts preset temperature to obtain first object temperature.
In the examples described above, when supposing that air-conditioner does not use within the regular hour, can think the Current Temperatures of indoor heat exchanger and current environmental temperature close.
2, the second target temperature is determined according to the design temperature of user.Wherein, in fact the second target temperature can be understood as is the design temperature of user.
3, with first object temperature, compressor is controlled in Preset Time, with the second target temperature, compressor is controlled after the preset lime.
Such as: current environmental temperature is 30 degrees Celsius, preset temperature is such as 2 degree, then first object temperature is 28 degree, and design temperature is such as 24 degree.Now, first can control air-conditioner with 28 degree for target is freezed, because current environmental temperature is 30 degree, differ less with 28 degree, therefore, the temperature of the parts such as air channel, indoor heat exchanger is not more big changes within a certain period of time, gives the heat trnasfer between associated components with the time of abundance, make the temperature between parts more close, reach balance.Therefore, sufficient heat transfer/biography cool time can be had between the parts (such as air channel, indoor heat exchanger and and the parts that close on of air channel, indoor heat exchanger) for air-conditioner, thus effectively can reduce and even eliminate expansion noise.Then, the temperature between relevant parts is tending towards equal and after reaching balance, makes temperature reach target temperature gradually with slower rate temperature change, therefore, can reduce further and even eliminate expansion noise.
According to the control method of the air-conditioner of the embodiment of the present invention, by the control to the frequency of compressor or the pressure of expansion valve, the temperature of indoor heat exchanger can be made slowly to reach target temperature with relatively slow rate temperature change, like this, sufficient heat transfer/biography cool time can be had between parts for air-conditioner, thus effectively can reduce even elimination expansion noise, avoid noise annoying users, promote Consumer's Experience.
In one embodiment of the invention, also comprise: judge whether the ongoing frequency of compressor reaches the frequency that in stillness mode, noise setting value is corresponding; If the ongoing frequency of compressor reaches the frequency that in stillness mode, noise setting value is corresponding, then control frequency-changeable compressor and stop raising frequency.
Specifically, 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.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, also comprise: detection background noise; If the noise variation rate of background noise is greater than preset value, then reduce rate temperature change.Wherein, detection module comprises: sound collector and/or mobile terminal, wherein, background noise, by being arranged on the sound collector acquisition in room and/or the acquisition for mobile terminal by communicating with air-conditioner, is sent to air-conditioner by sound collector or mobile terminal.In addition, mobile terminal is but is not limited to smart mobile phone or panel computer.Further, in the altitude range that sound collector is arranged on [1.5 meters, 1.8 meters].
Specifically, if the background noise difference that front and back detect for twice is comparatively large, be then probably that air-conditioner creates expansion noise.Therefore, may be air-conditioner parts between heat transfer/pass cool time or shorter, therefore, can improve and not improve the rate temperature change of indoor heat exchanger, conduct heat/pass the cold time between the parts of further increasing air-conditioner, thus eliminate or reduce expansion noise further, avoid noise annoying users, promote Consumer's Experience.
