[0029] Example 1

[0030] Figure 1 is a flow chart of a compressor noise reduction control method according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0031] Step S101, in the noise reduction mode, identifying the current operating state of the compressor; wherein the operating state includes a startup state and a stable operating state;

[0032] Step S102, if it is in the startup state, adjusting the frequency increase speed of the compressor to achieve noise reduction;

[0033] Step S103: If it is a stable operation state, the operating frequency of the compressor is adjusted according to the preset noise frequency to achieve noise reduction.

[0034] This embodiment changes the frequency increase speed or operating frequency of the compressor through a variety of control strategies according to different operating states of the unit, thereby shielding the frequency of noise generated by the compressor, thereby reducing the noise caused by the operation of the compressor, and quickly and efficiently solving the air conditioning noise problem, saving manpower and material resources, and improving the comfort of users using air conditioning.

[0035] When identifying the current operating status of the compressor, it can be identified based on the length of time the unit is turned on. For example, the initial preset time of the unit startup is generally in the startup state, such as within 3 minutes of startup. If it exceeds 3 minutes, it means that the compressor has entered a stable operating state. It can also be identified based on the frequency change of the compressor. If it is in a rapid frequency increase stage, it means it is in the startup state. If the frequency is relatively stable, it means it has entered a stable operating state.

[0036] The following describes the corresponding noise reduction strategies in different operating states to achieve the purpose of reducing the operating noise of the compressor.

[0037] If it is in the startup state, the frequency increase speed of the compressor can be regulated by the following preferred implementation method: obtaining the total capacity demand of all indoor units and the total rated capacity of the outdoor units; calculating the adjusted frequency increase speed according to the current frequency increase speed of the compressor, the total capacity demand of all indoor units, and the total rated capacity of the outdoor units; taking the minimum value between the adjusted frequency increase speed and the current frequency increase speed, and regulating the frequency increase speed of the compressor according to the minimum value.

[0038] Specifically, the adjusted up-conversion speed Vi is calculated by the following formula:

[0039] Vi=V*(Q 需 / Q e )*Z; where V is the current frequency upscaling speed, Q 需 is the total capacity requirement of all internal machines, Q e is the total rated capacity of the outdoor unit, and Z is the frequency correction value.

[0040] Prior to this, the frequency correction value Z is calculated by the following formula:

[0041] Z=0.5*(F 目 / (F 目 -F 运 )); where F 目 is the target operating frequency of the compressor, F 运 is the current operating frequency of the compressor.

[0042] Based on this, the frequency increase speed can be adjusted according to the operating conditions of the unit to avoid excessive noise caused by excessive frequency increase, thus solving the noise problem of the compressor when it is started.

[0043] If it is a stable operation state, the operating frequency of the compressor is regulated according to the preset noise frequency, and the preset noise frequency includes a single frequency point (one or more) and / or a continuous frequency segment (one or more), which can be achieved by the following preferred implementations:

[0044] The technical solution to avoid a single frequency point is as follows: obtain the current operating frequency of the compressor; determine whether the current operating frequency overlaps with a single frequency point, and if so, lower or increase the current operating frequency. Specifically, the regulated operating frequency value can be set = current operating frequency + k, or the regulated operating frequency value can be set = current operating frequency - k. Among them, k is a constant (for example, a value of 1). If the current operating frequency is already the preset minimum frequency, the regulated operating frequency value = current operating frequency + 1. Based on this, the operating frequency of the compressor can be controlled to avoid a single frequency point that causes louder noise, thereby ensuring that the noise during the operation stage of the compressor is low and improving the user experience.

[0045] The technical solution to avoid the continuous frequency segment is as follows: according to the frequency increase state or frequency reduction state of the compressor, determine whether the current operating frequency is about to fall into the continuous frequency segment. If so, determine the regulated operating frequency value according to the upper and lower limits of the continuous frequency segment and maintain it for a preset time. Specifically, if the compressor is in the frequency increase state and the current operating frequency is about to fall into the continuous frequency segment, determine the regulated operating frequency value = the lower limit value of the continuous frequency segment - k; if the compressor is in the frequency reduction state and the current operating frequency is about to fall into the continuous frequency segment, determine the regulated operating frequency value = the upper limit value of the continuous frequency segment + k.

[0046] Prior to this, the preset duration of each power-on internal unit is calculated according to the following formula x=40-ΔA: where ΔA is the time compensation value; ΔA=c*ΔT n +d*((ΔT n -ΔT n-1 )-(ΔT n-1 -ΔT n-2 )); where ΔT = T 环境 -T 设定 , T 环境 is the indoor ambient temperature, T 设定 is the preset temperature, periodically detects the indoor ambient temperature, n represents the serial number of the detection cycle, c and d are preset values, and the values ​​of c and d are different in different operating modes; in cooling mode, if T 环境 If the temperature exceeds the preset value, c = 1, d = 2; otherwise, c = 0.5, d = 1; in heating mode, if T 环境If the preset temperature is exceeded, c=0.5, d=1; otherwise, c=1, d=2. Afterwards, the minimum value is taken from the preset duration x of each startup of the indoor unit as the preset duration. Based on this, the operating frequency of the compressor can be controlled to avoid the continuous frequency segment that causes high noise, thereby ensuring low noise during the operation of the compressor and improving the user experience.

[0047] 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 can be executed simultaneously or independently. Both the single frequency point and the continuous frequency band are preset frequency points and frequency bands that can cause relatively large noise.

[0048] Example 2

[0049] Figure 2 is a detailed flow chart of a compressor noise reduction control method according to an embodiment of the present invention, such as Figure 2 As shown, the method comprises the following steps:

[0050] Step S201, entering noise reduction mode.

[0051] The unit has a reserved noise reduction mode in the program. The noise reduction mode can be entered manually through the button setting, or it can be triggered when the unit is turned on. After entering the noise reduction mode, the external digital tube will display the current operating frequency and frequency increase speed of the compressor, so that users can more easily understand the current operating status of the unit.

[0052] Step S202, confirming the running state of the unit when the noise is generated. In this embodiment, the running state of the unit is divided into: a starting state and a stable running state.

[0053] Step S203, determine whether the unit is in the startup state. If yes, execute step S204, if not, execute step S205.

[0054] Step S204, adjusting the up-conversion speed.

[0055] In the startup state, the difference between the target operating frequency and the actual operating frequency of the compressor is large, and the actual operating frequency of the compressor will change sharply in a short period of time. If the frequency increase speed is too fast, noise may be generated. Therefore, in this frequency range that is prone to noise, the frequency increase speed of the compressor can be reduced to reduce noise.

[0056] Specifically, the adjusted frequency increase speed Vi can be calculated by the following formula:

[0057] Vi=V*(Q 需 / Q e )*Z; where V is the current frequency upscaling speed, Q 需 is the total power requirement of all internal units (in kw), Q eis the total rated capacity of the outdoor unit (unit: kw), and Z is the frequency correction value.

[0058] Before this, the frequency correction value Z was calculated by the following formula:

[0059] Z = 0.5 * (F 目 / (F 目 - F 运 )); where F 目 is the target operating frequency of the compressor, and F 运 is the current operating frequency of the compressor. The value range of Z is [100%, 200%].

[0060] Take the minimum value between the adjusted frequency increase speed and the current frequency increase speed, and control the frequency increase speed of the compressor according to the minimum value.

[0061] After that, execute step S206.

[0062] Step S205, adjust the operating frequency of the compressor.

[0063] In the stable state, that is, when the compressor is running smoothly, the change in capacity demand is small, the frequency fluctuation is small, and the change is slow, then corresponding strategies can be adopted to shield the noise frequency.

[0064] For a single frequency point: Assume that the current operating frequency is A, and A is a noise frequency point, then lower or raise the current operating frequency. For example, perform A - 1 processing. If it is already the minimum frequency at this time, then perform A + 1 processing.

[0065] For a continuous frequency segment: When the noise frequencies are dense and form a continuous frequency segment, at this time, if only adding or subtracting 1 from the frequency value, the effect is not very good. It can stay at a frequency before the noise point. Assume that the frequency range where the noise is generated is [a, b]. When the compressor needs to pass through this interval, it needs to stay at (a - 1) HZ or (b + 1) HZ for X min (when the compressor frequency F > b, it stays at b + 1 when reducing the frequency; when the compressor frequency < a, it stays at a - 1 when increasing the frequency). The calculation method of time x is as follows:

[0066] x = 40 - ΔA;

[0067] The time x is related to the actual indoor environment temperature T 环 and the set temperature T 设 When considering the comfort of the room, when the indoor environment temperature changes slowly, the time x is appropriately shortened. When the indoor environment temperature changes quickly, then the time x is appropriately increased because the faster the indoor environment temperature changes, the better the current cooling or heating effect of the air conditioner.

[0068] ΔA is the time compensation value; ΔA = c * ΔTn +d*((ΔT n -ΔT n-1 )-(ΔT n-1 -ΔT n-2 ));

[0069] Where ΔT = T 环境 -T 设定 , T 环境 is the indoor ambient temperature, T 设定 is the preset temperature, periodically detects the indoor ambient temperature, n represents the serial number of the detection cycle, c and d are preset values, and the values ​​of c and d are different in different operating modes. In cooling mode: when T 环境 >26℃, c=1, d=2; when T 环境 ≤26℃, c=0.5, d=1. In heating mode: when T 环境 >26℃, c=0.5, d=1; when T 环境 When ≤26℃, c=1, d=2.

[0070] This embodiment uses the indoor ambient temperature of 26 as the demarcation point because in most cases, 26 is the most comfortable indoor temperature.

[0071] Finally, the minimum value is taken from the preset duration x of each power-on internal machine, which is taken as the final preset duration x.

[0072] Afterwards, execute step S206.

[0073] Step S206: the unit operates according to the adjusted parameters.

[0074] Through the above control method, the noise problem caused by the air-conditioning compressor can be solved quickly and efficiently to a large extent, thereby improving the comfort of users.
