Example 1
Fig. 1 is a flowchart of a compressor noise reduction control method according to an embodiment of the present invention, as shown in fig. 1, including the steps of:
Step S101, identifying the current running state of the compressor in a noise reduction mode, wherein the running state comprises a starting state and a steady running state;
step S102, if the starting state is the starting state, regulating and controlling the frequency raising speed of the compressor to realize noise reduction;
Step S103, if the running state is stable, the running frequency of the compressor is regulated and controlled according to the preset noise frequency so as to realize noise reduction.
According to different running states of the unit, the frequency raising speed or running frequency of the compressor is changed through various control strategies, so that the frequency of noise generated by the compressor is shielded, the noise caused by running of the compressor is reduced, and the problem of air conditioner noise is solved rapidly and efficiently. The manpower and material resources are saved, and the comfort of using the air conditioner by a user is improved.
When the current running state of the compressor is identified, the compressor can be identified according to the starting time of the unit, for example, the initial preset time for starting the unit is generally in a starting state, for example, within 3 minutes of starting. If it exceeds 3 minutes, it indicates that the compressor has entered a steady state operation. It can also be identified from the frequency variation of the compressor, indicating a start-up condition if in a fast up-conversion phase, and a steady running condition if the frequency is relatively steady.
The following describes the respective noise reduction strategies adopted under different operating conditions to achieve the purpose of reducing the operating noise of the compressor. If the compressor is currently in a start state
If the starting state is the starting state, the frequency raising speed of the compressor can be regulated and controlled by the following preferred implementation modes, namely, the total capacity requirement of all the internal machines and the total rated capacity of the external machines are obtained, the regulated frequency raising speed is calculated according to the current frequency raising speed of the compressor, the total capacity requirement of all the internal machines and the total rated capacity of the external machines, the minimum value is taken between the regulated frequency raising speed and the current frequency raising speed, and the frequency raising speed of the compressor is regulated and controlled according to the minimum value.
Specifically, the adjusted up-conversion speed Vi is calculated by the following formula:
Vi=v (Q Is required to /Qe) Z, where V is the current up-conversion speed, Q Is required to is the total capacity requirement of all internal units, Q e is the total rated capacity of the external unit, and Z is the frequency correction value.
Before this, the frequency correction value Z is calculated by the following formula:
Z=0.5 x (F Order of (A) /(F Order of (A) －F Transport and transport )), where F Order of (A) is the target operating frequency of the compressor and F Transport and transport is the current operating frequency of the compressor.
Based on this, can adjust its boost speed according to the running condition of unit, avoid its too fast noise that leads to of boost, the noise problem when solving the compressor at the starting state.
In the case of a steady operation, the operating frequency of the compressor is regulated according to a preset noise frequency, which comprises single frequency point(s) and/or continuous frequency segment(s), which can be achieved by the following preferred embodiments:
The technical scheme for avoiding the single frequency point comprises the steps of obtaining the current operating frequency of the compressor, judging whether the current operating frequency is overlapped with the single frequency point, and if so, reducing or increasing the current operating frequency, specifically, setting the regulated operating frequency value = the current operating frequency +k or setting the regulated operating frequency value = the current operating frequency-k. Where k is a constant (e.g., a value of 1). And if the current operating frequency is the preset minimum frequency, the regulated operating frequency value=the current operating frequency+1. Based on this, can control the running frequency of compressor and avoid single frequency point that can lead to great noise to guarantee that the noise of compressor operation stage is lower, promote user's use experience.
The technical scheme for avoiding the continuous frequency band is as follows, whether the current running frequency is about to fall into the continuous frequency band is judged according to the frequency-up state or the frequency-down state of the compressor, if so, the regulated running frequency value is determined according to the upper limit value and the lower limit value of the continuous frequency band, and the preset duration is maintained. Specifically, if the compressor is in an up-conversion state and the current operating frequency is about to fall into a continuous frequency band, a regulated operating frequency value = a lower limit value-k of the continuous frequency band is determined, and if the compressor is in a down-conversion state and the current operating frequency is about to fall into the continuous frequency band, an upper limit value +k of the regulated operating frequency value = the continuous frequency band is determined.
Before, the preset time length x=40- Δa of each startup internal machine is calculated according to the following formula, wherein Δa is a time compensation value, Δa=c is Δt n+d*((ΔTn-ΔTn-1)－(ΔTn-1-ΔTn-2), Δt=t Environment (environment) －T Setting up ,T Environment (environment) is an indoor environment temperature, T Setting up is a preset temperature, the indoor environment temperature is periodically detected, n represents the serial numbers of detection periods, c and d are preset values, the values of c and d are different in different operation modes, c=1 and d=2 if T Environment (environment) exceeds the preset temperature in a refrigeration mode, c=0.5 and d=1 otherwise, c=0.5 and d=1 if T Environment (environment) exceeds the preset temperature in a heating mode, and c=1 and d=2 otherwise. And then, taking the minimum value in the preset time length x of each startup internal machine as the preset time length. Based on this, can control the running frequency of compressor and avoid the continuous frequency section that can lead to great noise to guarantee that the noise of compressor operation stage is lower, promote user's use experience.
It should be noted that, the above technical solution for avoiding a single frequency point and the above technical solution for avoiding a continuous frequency band may be executed simultaneously or may be executed independently. The single frequency point and the continuous frequency band are both preset frequency points and frequency bands which cause large noise.
Example 2
Fig. 2 is a detailed flowchart of a compressor noise reduction control method according to an embodiment of the present invention, as shown in fig. 2, including the steps of:
step S201, entering a noise reduction mode.
The noise reduction mode is reserved in the program of the unit, can be manually entered through key setting, and can be triggered when the unit is started. After entering the noise reduction mode, the external machine nixie tube can display the current running frequency and the frequency raising speed of the compressor, so that a user can conveniently and quickly know the current running state of the unit.
Step S202, the running state of the unit when noise is generated is confirmed. The embodiment divides the running state of the unit into a starting state and a steady running state.
Step S203, judging whether the unit is in a starting state. If yes, step S204 is performed, and if no, step S205 is performed.
Step S204, adjusting the frequency raising speed.
In the starting state, the difference between the target operating frequency and the actual operating frequency of the compressor is large, the actual operating frequency of the compressor can be changed rapidly in a short time, and noise can be generated due to the fact that the frequency raising speed is too high. Therefore, in the frequency range where noise is easily generated, the frequency raising speed of the compressor can be reduced to reduce noise.
Specifically, the adjusted up-conversion speed Vi may be calculated by the following formula:
Vi=v (Q Is required to /Qe) Z, where V is the current up-conversion speed, Q Is required to is the total capacity requirement (in kw) of all internal units, Q e is the total rated capacity (in kw) of the external units, and Z is the frequency correction value.
Before this, the frequency correction value Z is calculated by the following formula:
Z=0.5 x (F Order of (A) /(F Order of (A) －F Transport and transport )), where F Order of (A) is the target operating frequency of the compressor and F Transport and transport is the current operating frequency of the compressor. The value range of Z is [100%,200% ].
And taking a minimum value between the adjusted frequency-raising speed and the current frequency-raising speed, and regulating the frequency-raising speed of the compressor according to the minimum value.
After that, step S206 is performed.
Step S205, adjusting the compressor operating frequency.
In steady state, i.e. when the compressor is running steadily, the capacity requirement change is small, the frequency fluctuation is small, the change is slow, and then the noise frequency can be shielded by adopting a corresponding strategy.
For a single frequency bin, assuming that the current operating frequency is A and A is the noise frequency bin, the current operating frequency is turned down or up, for example, A-1 processing is performed, and if it is already the minimum frequency at this time, A+1 processing is performed.
For the continuous frequency band, if the noise frequency is dense to form a continuous frequency band, and at the moment, if the frequency value is only increased or decreased by 1, the effect is not very good, the continuous frequency band can stay at a frequency in front of the noise point, and if the frequency band generating noise is [ a, b ], the compressor needs to stay at (a-1) HZ or (b+1) HZ for Xmin when the compressor frequency F > b, stay at b+1 when the compressor frequency F > b, and stay at a-1 when the compressor frequency < a, and stay at a-1 when the compressor frequency is increased. The calculation method of the time x is as follows:
x=40-ΔA;
The time x is related to the actual environment temperature T Ring(s) of the internal machine and the set temperature T Is provided with , and is properly shortened when the indoor environment temperature changes slowly and properly increased when the indoor environment temperature changes quickly in consideration of the comfort of the room, because the current refrigerating or heating effect of the air conditioner is better when the indoor environment temperature changes faster.
Δa is the time offset value, Δa=c×Δt n+d*((ΔTn-ΔTn-1)－(ΔTn-1-ΔTn-2);
Wherein Δt=t Environment (environment) －T Setting up ,T Environment (environment) is an indoor environment temperature, T Setting up is a preset temperature, the indoor environment temperature is periodically detected, n represents a sequence number of a detection period, c and d are preset values, and the values of c and d are different in different operation modes. In the cooling mode, c=1, d=2 when T Environment (environment) >26 ℃, and c=0.5, d=1 when T Environment (environment) is less than or equal to 26 ℃. In the heating mode, c=0.5 and d=1 when T Environment (environment) is greater than 26 ℃, and c=1 and d=2 when T Environment (environment) is less than or equal to 26 ℃.
The present embodiment is bounded by the indoor ambient temperature 26 because in most cases, 26 is the most comfortable indoor temperature.
And finally, taking the minimum value in the preset duration x of each startup internal machine as the final preset duration x.
After that, step S206 is performed.
And step S206, the unit operates according to the adjusted parameters.
Through the control mode, the noise problem brought by the air conditioner compressor can be solved to a great extent, and the use comfort of a user is improved.
