The air conditioning system generally comprises an indoor unit and an outdoor unit, wherein the outdoor unit is provided with a compressor, an outdoor heat exchanger and a throttling device, and the indoor unit is provided with an indoor heat exchanger. When the air conditioner operates in a refrigeration mode, the refrigerant discharged by the compressor sequentially passes through the outdoor heat exchanger, the throttling device and the indoor heat exchanger, and finally returns to the compressor for recompression. When the air conditioner operates in a heating mode, the refrigerant discharged through the compressor sequentially passes through the indoor heat exchanger, the throttling device and the outdoor heat exchanger, and finally returns to the compressor for recompression.
In the above process, the compressor is the main power source of the refrigerant circulation system, so that the compressor can vibrate during the working process of the compressor, and the vibration can generate great noise, especially when the compressor is just started or the compressor is operated at high frequency, the generated noise is great, thereby causing great trouble to users.
As shown in fig. 1, the present embodiment provides a noise reduction device including a housing 10, the housing 10 being provided at the periphery of a compressor and forming a gap with the outer surface of the compressor; the vacuum pump is communicated with the gap and is used for vacuumizing the gap. By arranging the vacuum pump communicated with the gap to vacuumize the gap before the compressor works, a vacuum zone can be constructed at the periphery of the compressor, so that even if the compressor vibrates to generate noise, the noise cannot be transmitted outwards through the vacuum zone, and a good noise reduction effect is realized.
In the present embodiment, a first through hole through which a pipe connected to the compressor and a wiring are passed is formed at the top of the casing 10, the first through hole being for passing a discharge pipe of the compressor, an intake pipe of the compressor, and the wiring of the compressor; the edge of the first through hole is outwards protruded to form a first protection pipe section 11, and the first protection pipe section 11 is higher than the top surface of the housing 10, and the inner diameter of the first protection pipe section is matched with the exhaust pipe, the air suction pipe and the like of the compressor.
In the present embodiment, the vacuum pump is connected to the inner side wall of the casing 10, or to the outside of the casing 10. A second through hole 12 is formed on a sidewall surface of the casing 10, and an edge of the second through hole 12 may be inwardly protruded to form a second guard pipe section, and an exhaust port of the vacuum pump is connected to the second through hole 12 by means of a hose, and an intake port of the vacuum pump is further communicated with the gap to exhaust air in the gap, so that a vacuum environment may be constructed at an outer periphery of the compressor. Wherein, in order to facilitate the installation of the housing 10, a screw seat 12 is provided at the bottom of the housing 10.
In some embodiments, after the air conditioning system receives the start signal, the controller controls the compressor to be in a standby state first, and the compressor does not emit noise at this time; the controller controls the vacuum pump to start working, vacuumizes the gap between the compressor and the housing, thereby constructing a vacuum environment at the periphery of the compressor, and then controls the compressor to start, and the air conditioning system starts working. Thus, noise generated by the operation of the compressor cannot be spread through air, and the purpose of noise reduction of the compressor is achieved.
In some embodiments, as shown in fig. 2, an embodiment of the present disclosure provides a control method for noise reduction of an air conditioner, including:
s10: when the air conditioner is started, the processor 100 controls the vacuum pump to be started;
s20: acquiring the exhaust temperature or the exhaust pressure of the compressor;
s30: the processor 100 controls the operation speed of the motor of the vacuum pump according to the discharge temperature or discharge pressure of the compressor.
When the air conditioner is started, the compressor is in low-load operation, so that the operation frequency of the compressor is low. At this time, the compressor is in an unstable state, and the torque of the compressor is large, so that the compressor vibrates, and noise is generated. Therefore, when the air conditioning system just runs, the compressor runs unstably and has high noise, and the vacuum pump is controlled to start for noise reduction. With the gradual rise of the exhaust temperature or the gradual increase of the exhaust pressure of the compressor, the running speed of the motor of the vacuum pump is increased, so that the power of the vacuum pump is increased, and the vacuum can be rapidly pumped, thereby realizing a good noise reduction effect; when the exhaust temperature of the compressor is gradually stable and the noise is smaller, the running rotating speed of the motor is gradually reduced. Therefore, the noise reduction effect can be met, and the energy consumption of the vacuum pump can be reduced.
Optionally, the processor 100 controls the operating speed of the motor of the vacuum pump according to the discharge temperature or discharge pressure of the compressor. Wherein, the running modes of the air conditioner are different, and the exhaust temperature or the exhaust pressure requirement is also different; for this reason, the accurate acquisition of the discharge temperature or discharge pressure of the compressor affects the operation speed of the motor of the vacuum pump. In this embodiment, the air conditioner is provided with a temperature sensor or a pressure sensor for monitoring the exhaust position of the compressor, and the temperature sensor or the pressure sensor is electrically connected to the processor 100 and transmits an exhaust temperature signal or an exhaust pressure signal of the compressor to the processor 100 in real time.
In some embodiments, the higher the discharge temperature or discharge pressure of the compressor, the faster the motor speed of the vacuum pump.
In this embodiment, the air conditioning system has a plurality of noise reduction levels L, each corresponding to the rotational speed n of the motor in the vacuum pump. By way of example, the air conditioning system has 10 noise reduction levels L, which may be 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10. Optionally, as the noise reduction level increases, the rotational speed of the motor gradually increases.
In this embodiment, when the cooling or heating requirement is large, the operation speed of the motor of the vacuum pump is controlled by the exhaust temperature of the compressor, and the compressor needs to raise the exhaust temperature of the refrigerant. When the refrigerating or heating requirement is reduced, the air conditioning system is started for 2-level noise reduction, and the rotating speed of the motor operates at the second rotating speed, so that the noise reduction effect can be met, and the energy consumption of the vacuum pump can be reduced.
Optionally, as shown in fig. 3, the processor 100 controls the operation rotation speed of the motor of the vacuum pump according to the discharge temperature or discharge pressure of the compressor, including:
s21: when the exhaust temperature of the compressor is greater than or equal to a first preset temperature or the exhaust pressure of the compressor is greater than or equal to a first preset pressure, determining the motor rotating speed of the vacuum pump as a first running rotating speed;
s22: the processor 100 controls the motor of the vacuum pump to operate at a first rotational speed.
Optionally, the value range of the first preset temperature is 65 ℃ to 75 ℃;
in this embodiment, the motor speed of the vacuum pump depends on the value range of the first preset temperature. If the first preset temperature is 65 ℃, the rotating speed of the motor operates at a fourth rotating speed, and the air conditioning system reduces noise for 4 stages; the first preset temperature is 70 ℃, the rotating speed of the motor operates at a fifth rotating speed, and the air conditioning system is used for 5-stage noise reduction; the first preset temperature is 75 ℃, the rotating speed of the motor operates at a sixth rotating speed, and the air conditioning system reduces noise for 6 stages.
In this embodiment, the exhaust temperature of the compressor is greater than the first preset temperature, and the motor speed of the vacuum pump needs to be increased to the target speed to meet the purpose of noise reduction, that is, the motor of the vacuum pump operates at the first speed.
Optionally, the value range of the first preset pressure is 2.5Mpa to 2.6Mpa, and the adjustment mode of the motor rotation speed is the same as the adjustment mode according to the exhaust temperature, which is not described herein.
In this embodiment, the noise reduction level of the air conditioning system may be changed according to the actual use requirement of the user, so as to change the motor rotation speed of the vacuum pump.
Optionally, as shown in fig. 4, an embodiment of the present disclosure provides another control method for noise reduction of an air conditioner, including:
s31: when the air conditioner is started, the processor 100 controls the vacuum pump to be started;
s32: acquiring the exhaust temperature or the exhaust pressure of the compressor;
s33: the processor 100 controls the operation rotation speed of the motor of the vacuum pump according to the exhaust temperature or the exhaust pressure of the compressor;
s34: acquiring the operating frequency of a compressor;
s35: the processor 100 controls the operation of the vacuum pump for a set period of time according to the operating frequency of the compressor.
In this embodiment, the operation speed and the operation duration of the vacuum pump are controlled by the exhaust temperature or the exhaust pressure of the compressor and the operation frequency of the compressor, so that the energy consumption of the vacuum pump can be further reduced.
In this embodiment, the exhaust temperature or the exhaust pressure of the compressor may also be adjusted to adjust the operating frequency of the compressor, thereby controlling the operation setting time period of the vacuum pump.
In this embodiment, if the operation frequency of the compressor is always unstable, the vacuum pump needs to continuously operate to ensure that noise of the compressor is not transmitted to the external environment, but when the operation frequency of the compressor is stable, the rotation speed of the vacuum pump motor can be reduced by the exhaust temperature or the exhaust pressure of the compressor, and the power of the vacuum pump is gradually reduced.
However, when the compressor is operated at a stable frequency, the rotation speed of the vacuum pump is reduced, and the vacuum pump may be directly turned off in order to further reduce the power consumption of the vacuum pump.
In some embodiments, the operating frequency of the compressor is gradually increased to a set frequency or gradually decreased to a set frequency, and the vacuum pump is controlled to operate for a first set period of time.
In this embodiment, according to the requirement of the user, the operation frequency of the compressor gradually increases, after increasing to a certain frequency, the use requirement of the user is satisfied, and the operation frequency of the compressor gradually tends to be stable. The working time of the vacuum pump is the time when the operating frequency of the compressor gradually rises to the stable frequency, at the moment, the temperature and the pressure of the refrigerant in the air conditioning system also tend to be stable, the noise generated by the compressor is small, and at the moment, the vacuum pump can be closed.
In this embodiment, the operating frequency of the compressor gradually decreases, and after decreasing to a certain frequency, the operating frequency of the compressor gradually tends to be stable, and the vacuum pump may also be turned off.
Optionally, as shown in fig. 5, the processor 100 controls the operation of the vacuum pump for a set period of time according to the operation frequency of the compressor, including:
s41: the compressor operates at a set first operating frequency and continuously operates for a first preset time period, and the vacuum pump is determined to be closed;
s42: the processor 100 adjusts the vacuum pump to an off state.
In this embodiment, the operating time period of the vacuum pump depends on the operating frequency of the compressor and the duration of the compressor operation at that operating frequency. The first operating frequency is exemplified by a range of values from 30Hz to 60Hz. The first preset time period may be 10min, 15min or 20min.
In this embodiment, if the operating frequency of the compressor is 40Hz and the operation is continued for 15min, the torque of the compressor is smaller than that just when the compressor is started, and the noise is smaller, which indicates that the operating frequency of the compressor is stable. When the air conditioner operates, the door and window are in a closed state, and the noise of the compressor is hardly transmitted to the indoor side, so that the generated noise does not influence a user, and the vacuum pump is closed, so that the energy consumption of the vacuum pump is reduced.
In this embodiment, the first operating frequency of the compressor and the first preset time period need to be satisfied simultaneously to turn off the vacuum pump. The operation time length of the vacuum pump can be changed according to the actual use requirement of a user, and the purpose of noise reduction is guaranteed to be met.
In some embodiments, the vacuum pump is controlled to be turned off in the case where the air conditioner is operated in a comfort mode, a power saving mode, or a sleep mode.
In the present embodiment, in the case where the air conditioner is operated in the comfort mode, the energy saving mode, or the sleep mode, the operation frequency of the compressor is stabilized and the smaller load is operated. At this time, the torque of the compressor is small and vibration is small when the compressor is operated, so that noise generated does not affect the user.
Here, taking the operation of the air conditioner in the sleep mode as an example, for example, a button of the sleep mode is set on the air conditioner remote controller, the user starts the sleep mode by pressing the button, or the user can also realize the opening of the sleep mode through a user end communicating with the server or the air conditioner, where the user end may be an APP installed on a mobile terminal, and the mobile terminal includes, but is not limited to, a mobile phone, a tablet computer, and the like. The vacuum pump is controlled to be turned off by acquiring the frequency of the compressor or the processor 100 directly controls the vacuum pump to be turned off in the sleep mode, so that the energy consumption of the vacuum pump is reduced and the cold and hot effects of the air conditioner are ensured.
