In addition, without conflict, those skilled in the art can combine the different embodiments or examples described in this specification and the features of the different embodiments or examples.

[0050] The present invention provides a control method for frequency reduction of an air conditioner, which can be a wall-mounted air conditioner, a floor-standing air conditioner, a window air conditioner, a ceiling-mounted air conditioner, etc.

[0051] As Figure 1 and Figure 2 shown, a variable flow splitting device is provided in the indoor heat exchanger of the air conditioner, or a variable flow splitting device is provided in the outdoor heat exchanger, or variable flow splitting devices can be provided in both the indoor heat exchanger and the outdoor heat exchanger at the same time. The variable flow splitting device includes: a reversing valve 3, a first flow splitting pipeline 1, a second flow splitting pipeline 2, and at least two heat exchange pipelines 4. The first flow splitting pipeline 1 is connected to the second flow splitting pipeline 2 through at least two heat exchange pipelines 4. Both the first flow splitting pipeline 1 and the second flow splitting pipeline 2 are provided with a main pipeline and a plurality of branch pipelines, and check valves 10 can be provided in some of the branch pipelines as required.

[0052] The reversing valve 3 is a two-position four-way reversing valve, which is provided with a first communication port 31, a second communication port 32, a third communication port 33, and a fourth communication port 34. The reversing valve 3 has a first working position and a second working position. The first communication port 31 is connected to the refrigerant inlet, and the third communication port 33 is connected to the refrigerant outlet.

[0053] The flow splitting states are single-path flow splitting and multi-path flow splitting. In the case of multi-path flow splitting, the refrigerant in the outdoor heat exchanger of the air conditioner operates with multi-path flow splitting. In the case of single-path flow splitting, the refrigerant in the outdoor heat exchanger of the air conditioner operates with single-path flow.

[0054] During multi-path flow splitting, the reversing valve 3 is in the first working position, the first communication port 31 is communicated with the second communication port 32, and the third communication port 33 is communicated with the fourth communication port 34. At this time, the second communication port 32 is communicated with the first flow splitting pipeline 1, and the fourth communication port 34 is communicated with the second flow splitting pipeline 2. The refrigerant at the refrigerant inlet enters through the first flow splitting pipeline 1, is split in the branch pipelines of the first flow splitting pipeline 1, enters each heat exchange pipeline 4 respectively to exchange heat with the indoor air, then enters the main pipeline of the second flow splitting pipeline 2 through the branch pipelines of the second flow splitting pipeline 2, and finally is discharged from the refrigerant outlet through the fourth communication port 34 and the third communication port 33, realizing heat exchange through multiple pipelines.

[0055] During single-path flow splitting, the reversing valve 3 is in the second working position, the first communication port 31 is communicated with the fourth communication port 34, and the third communication port 33 is communicated with the second communication port 32. At this time, the second communication port 32 is communicated with the second flow splitting pipeline 2, and the fourth communication port 34 is communicated with the first flow splitting pipeline 1. The refrigerant at the refrigerant inlet enters through the second flow splitting pipeline 2. Due to the check valves 10 provided in some of the pipelines in the first flow splitting pipeline 1, under their restriction, the refrigerant can only be exchanged and discharged in some of the heat exchange pipelines 4. At this time, the number of heat exchange pipelines can be reduced.

[0056] In this embodiment, taking two heat exchange pipelines 4 as an example, they are a first heat exchange pipeline and a second heat exchange pipeline respectively. Both the first shunt pipeline 1 and the second shunt pipeline 2 are provided with a main pipeline and two branch pipelines. A check valve 10 is provided in one of the branch pipelines of the first shunt pipeline 1. It is assumed that the check valve 10 is provided only in one of the branch pipelines of the first shunt pipeline 1

[0057] During multi-way shunting, the reversing valve 3 is in the first working position, the first communication port 31 is communicated with the second communication port 32, and the third communication port 33 and the fourth communication port 34 are communicated. At this time, the second communication port 32 is communicated with the first shunt pipeline 1, and the fourth communication port 34 is communicated with the second shunt pipeline 2. The refrigerant at the refrigerant inlet enters from the first shunt pipeline 1, is shunted in the branch pipeline of the first shunt pipeline 1, and respectively enters the first heat exchange pipeline and the second heat exchange pipeline to exchange heat with the indoor air, then enters its main pipeline from the branch pipeline of the second shunt pipeline 2, and finally passes through the fourth communication port 34 and the third communication port 33 and is discharged from the refrigerant outlet, realizing the simultaneous heat exchange of the two pipelines.

[0058] During single-way shunting, the reversing valve 3 is in the second working position, the first communication port 31 is communicated with the fourth communication port 34, and the third communication port 33 is communicated with the second communication port 32. At this time, the second communication port 32 is communicated with the second shunt pipeline 2, and the fourth communication port 34 is communicated with the first shunt pipeline 1. The refrigerant at the refrigerant inlet enters from the second shunt pipeline 2. Due to the check valve 10 provided in the branch pipeline of the first shunt pipeline 1, under its restriction, the refrigerant can only be exchanged and discharged in the first heat exchange pipeline 4. At this time, heat exchange is only carried out through one heat exchange pipeline 4.

[0059] As Figure 3 shown, the air conditioner frequency reduction control method includes the following steps:

[0060] Step S310: Obtain the current value during the operation of the air conditioner.

[0061] After the air conditioner is turned on, the air conditioner detects the current value during the operation of the air conditioner in real time through a sensor, and compares the current value with a preset value.

[0062] Among them, the preset value can be adjusted according to user needs. The preset value is generally 120% of the current value during normal operation. When the current value reaches 120% of the normal value, it indicates that the current value in the air conditioner is abnormal.

[0063] Step S320: Adjust the shunt state of the air conditioner based on the current value.

[0064] After obtaining the current value during the operation of the air conditioner, the shunt state of the air conditioner is adjusted based on the current value. If the current value is greater than the preset value, it means that the current in the air conditioner is abnormal, and the shunt state is adjusted at this time; if the current value is less than or equal to the preset value, it means that the current in the air conditioner is normal, and the current shunt state is maintained for operation.

[0065] Specifically, in this embodiment, when the air conditioner is cooling and the current is large, the temperature of the computer board of the air conditioner is high, and the outdoor heat exchanger acts as a condenser at this time. The computer board of the air conditioner is set in the outdoor unit, and the radiator of the computer board of the air conditioner is cooled by the air entering the outdoor unit. Before adjusting the diversion state, the diversion of the condenser in the outdoor unit directly enters the pipe from the compressor. Assuming that the refrigerant enters the condenser from the top at this time, and the cold air entering the heat exchange first passes through the top of the condenser for heat exchange and then to the radiator of the computer board, because the cold air first passes through the condenser for heat exchange, the temperature of the cold air passing through the radiator is high, which is not conducive to the heat dissipation of the computer board.

[0066] After adjusting the diversion state, the position where the refrigerant enters the condenser is changed. Assuming that the refrigerant enters the condenser from the bottom at this time, the temperature above the condenser is lowered, and the cold air first passes through the top of the condenser for heat exchange and then reaches the radiator of the computer board, thereby reducing the inlet air temperature entering the radiator to a certain extent and improving the heat dissipation effect of the computer board.

[0067] Step S330: Acquire the temperature changes of relevant components during the operation of the air conditioner.

[0068] After adjustment, the air conditioner continues to obtain the temperature changes of related components during the operation of the air conditioner through sensors. For example, the temperature of the outdoor heat exchanger or the air conditioner circuit board radiator, air conditioner circuit board and other structures can be obtained.

[0069] Step S340: adjusting the operating frequency of the air conditioner based on the temperature change.

[0070] If the temperature change of the relevant components is still high after the circuit is switched, the operating frequency of the air conditioner is adjusted according to the temperature change of the relevant components, and the air conditioner is controlled to reduce the frequency to work. If the temperature change of the relevant components is normal after the circuit is switched, the air conditioner can be controlled to maintain the current frequency to work.

[0071] The air conditioner frequency reduction control method provided in the embodiment of the present invention obtains the current value of the air conditioner during the operation of the air conditioner, and adjusts the shunt state of the air conditioner based on the current value. In this process, the temperature changes of related components during the operation of the air conditioner are continuously obtained, and the operating frequency of the air conditioner is adjusted based on the temperature changes. Compared with the control method of directly adjusting the air conditioner frequency, the present application can reduce the frequency modulation ratio, control the air conditioner frequency reduction while trying to meet the user's cooling capacity requirements, and improve the user experience.

[0072] To further reduce the temperature,Figure 4 As shown, the steps of adjusting the shunt state of the air conditioner based on the current value include:

[0073] Step S410: When the current value is greater than the preset value, obtain the shunt state; wherein, the shunt state includes: single-path shunt and multi-path shunt.

[0074] When the obtained current value is greater than the preset value, it indicates that the current in the air conditioner is abnormal, which is extremely likely to cause the temperature of the air conditioner circuit board to be abnormal. To reduce the temperature, the air conditioner obtains the current shunt state of the outdoor heat exchanger of the air conditioner through a sensor. The shunt state includes: single-path shunt and multi-path shunt.

[0075] Step S420: If the air conditioner is in a single-path shunt, adjust it to a multi-path shunt for operation.

[0076] Adjust the shunt state of the outdoor heat exchanger to switch the outdoor heat exchanger between single-path shunt and multi-path shunt. Three-way or four-way heat exchange pipelines can also be set as required, so that the shunt state can also be set to an intermediate state of partial shunt to ensure selection according to needs during operation.

[0077] If the air conditioner is in a single-path shunt at this time, adjust the outdoor heat exchanger to a multi-path shunt for operation. When the air conditioner is in a multi-path shunt for refrigeration, heat dissipation is carried out by multiple refrigerant circuits, which can effectively reduce the inlet air temperature entering the radiator and improve the heat dissipation effect of the computer board.

[0078] When three-way or four-way heat exchange pipelines are provided, if the air conditioner is in a single-path shunt, it can also be adjusted to a partial shunt for operation. Compared with the single-path shunt, the partial shunt can improve the heat dissipation effect and reduce the temperature of the air conditioner computer board radiator.

[0079] Step S430: If the air conditioner is in a multi-path shunt, keep it in a multi-path shunt for operation.

[0080] If the air conditioner is in a multi-path shunt at this time, no corresponding adjustment is made to the air conditioner, and the outdoor heat exchanger is controlled to continue to operate in a multi-path shunt.

[0081] Based on the above embodiments, as Figure 5 shown, the steps of obtaining the temperature change of relevant components during the operation of the air conditioner include:

[0082] Step S510: Obtain the first temperature when the outdoor heat exchanger is not working and the second temperature after adjusting the shunt state.

[0083] After adjusting the shunt state, obtain the first temperature when the outdoor heat exchanger is not working, and at the same time obtain the second temperature of the outdoor heat exchanger after adjusting the shunt state through a sensor. The first temperature and the second temperature can both be the inlet temperature or the outlet temperature in the outdoor heat exchanger.

[0084] Step S520: Determine the temperature change based on the first temperature and the second temperature.

[0085] After obtaining the first temperature and the second temperature, determine the temperature difference between the first temperature and the second temperature, and the temperature change can be determined according to the temperature difference.

[0086] After obtaining the temperature change, if the temperature change is greater than the preset temperature rise, that is, after adjusting the shunt state, the temperature still cannot be reduced to the normal range, then control the air conditioner to operate at a reduced frequency, thereby reducing the operating frequency of the compressor and reducing the refrigerant temperature.

[0087] In this process, if the temperature change is greater than the preset temperature rise, in order to be able to reduce the reduced frequency, then determine the difference between the temperature change and the preset temperature rise. Based on the difference, determine the frequency reduction value of the air conditioner. Specifically, for example, when the difference between the temperature change and the preset temperature rise is 5°C, the frequency reduction value is 20 Hz, then the compressor frequency is reduced by 20 Hz. When the difference between the temperature change and the preset temperature rise is 10°C, the frequency reduction value is 40 Hz, then the compressor frequency is reduced by 40 Hz.

[0088] If the temperature change is less than or equal to the preset temperature rise, it means that after adjusting the shunt state, the temperature has been able to be reduced to the normal range, then control the air conditioner to maintain the current working state.
