Description

TECHNICAL FIELD

[0001] The present application relates to the air conditioning technical field, and in particular, relates to a to-warm shutdown suppression control method and device of an air conditioner and the air conditioner. BACKGROUND

[0002] When the indoor environment temperature exceeds the set value, the to-warm shutdown control is usually performed when the air conditioner is in low load operation. However, this to-warm shutdown control method needs to control the compressor to stop running first, and a waiting time will be generated when restarting, which is easy to cause a large fluctuation of the indoor temperature in a short time and affect the comfort of the indoor environment.

[0003] The existing to-warm shutdown suppression control technology usually suppresses the air conditioning refrigeration or heating capacity by bypassing part of the discharged refrigerant to the suction side of the compressor, so as to reduce the frequency of entering the to-warm shutdown control. However, discharging part of the compressed refrigerant to the bypass branch will lose part of the energy used for compression. In the case of the same compressor frequency, the larger the bypass amount, the lower the efficiency. When the bypass valve opening degree of the bypass branch is increased in order to improve the comfort, the problem of excessive suppression of to-warm shutdown leading to a decrease in refrigeration or heating efficiency is easy to occur. SUMMARY

[0015] When the average temperature arrival stoppage time is greater than the first preset time length or the average temperature arrival startup time is less than the second preset time length, it is monitored whether the running frequency of the compressor reaches a minimum frequency.

[0047] The embodiments of the present application are described below by specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in the specification. Obviously, the described examples are part of the examples of the present application, not all. Based on the examples in the present application, all other examples obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0048] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0049] The present embodiment provides a temperature reaching stop machine suppression control method of an air conditioner, which can be applied to an air conditioner, as shown in Figure 1The flow chart of the to-temperature stoppage inhibition control method of the air conditioner is shown, and the method mainly comprises the following steps S102-S106:

[0050] Step S102: When the air conditioner starts to run, the number of to-temperature stoppages of the air conditioner is detected.

[0051] When the air conditioner starts to run in the cooling mode or the heating mode, the number of to-temperature stoppages of the air conditioner is counted based on the counter.

[0052] Referring to the structural schematic diagram of the air conditioner as shown in Figure 2 The air conditioner provided in the embodiment comprises an indoor unit 10 and an outdoor unit 20. The outdoor unit 20 comprises a compressor 21, a four-way valve 22 and a bypass valve 23. The indoor unit 10 comprises a heat exchanger 11. The bypass valve 23 is arranged on a bypass branch. One end of the bypass branch is connected between the discharge pipe of the compressor 21 and the four-way valve 22. The other end of the bypass branch is connected between the heat exchanger 11 of the indoor unit 10 and the compressor 21. As shown in Figure 2 The outdoor unit 20 further comprises a heat exchanger 24, a capillary tube 25, a maintenance liquid valve 26 and a maintenance gas valve 27.

[0053] Step S104: When the number of to-temperature stoppages is greater than or equal to the preset number, the to-temperature stoppage average time or the to-temperature start average time is obtained.

[0054] The preset number can be 2-5 times, preferably 3 times. When the number of to-temperature stoppages is greater than or equal to the preset number, it indicates that the frequency of to-temperature stoppages is high. In order to avoid affecting the comfort of the user, the to-temperature stoppage average time or the to-temperature start average time before is obtained, such as when the number of to-temperature stoppages is greater than or equal to 3, the to-temperature stoppage average time or the to-temperature start average time corresponding to the previous two to-temperature stoppages is obtained.

[0055] The inventor has found that in the to-temperature stoppage control, within a certain time range, the temperature fluctuation is not easy to be perceived, and therefore the user feels less discomfort. In the cooling mode, the to-temperature stoppage time is an important factor. If the to-temperature stoppage time is within a certain time length, the user is not easy to feel discomfort. In the heating mode, the to-temperature start time (the to-temperature start time is the time from the restart of the compressor to the start of operation) is an important factor. If the to-temperature start time exceeds a certain time length, the user is not easy to feel discomfort.

[0056] In a specific embodiment, when the air conditioner runs in the cooling mode, the to-temperature stoppage average time is determined based on the to-temperature stoppage time of each time when the number of to-temperature stoppages is less than the preset number.

[0057] The ratio of the sum of the warm-up stop times when the number of warm-up stops is less than the preset number to the number of warm-up stops is calculated to obtain the average warm-up stop time; for example, the preset number is 3, and the average warm-up stop time is obtained based on the ratio of the sum of the warm-up stop times when the number of warm-up stops is less than 3 to 2.

[0058] When the air conditioner is in the heating mode, the average warm-up start time is determined based on the warm-up start time when the number of warm-up stops is less than the preset number.

[0059] The ratio of the sum of the warm-up start times when the number of warm-up stops is less than the preset number to the number of warm-up stops is calculated to obtain the average warm-up start time; for example, the preset number is 3, and the average warm-up start time is obtained based on the ratio of the sum of the warm-up start times when the number of warm-up stops is less than 3 to 2.

[0060] Step S106: Determine whether the average warm-up stop time or the average warm-up start time is within the preset comfortable time range. When the average warm-up stop time or the average warm-up start time is not within the preset comfortable time range, the bypass valve is opened.

[0061] The preset comfortable time range corresponding to the average warm-up stop time or the average warm-up start time is different. When the average warm-up stop time is less than or equal to a certain time length, it is within the preset comfortable time range. When the average warm-up start time is greater than or equal to a certain time length, it is within the preset comfortable time range.

[0062] By controlling the opening and closing state of the bypass valve according to the average warm-up stop time or the average warm-up start time, the opening and closing of the bypass valve can be controlled without affecting the comfort of the user, thereby effectively suppressing the warm-up stop, and thus reducing the time of efficiency decline to the shortest time.

[0063] The above-mentioned warm-up stop suppression control method of the air conditioner provided by the embodiment, by detecting that the number of warm-up stops of the air conditioner is large, determining whether the average warm-up stop time in the cooling mode or the average warm-up start time in the heating mode is within the preset comfortable time range, and opening the bypass valve when the average warm-up stop time or the average warm-up start time is not within the preset comfortable time range, the opening time of the bypass valve is limited within a fixed time period, and the occurrence period of the warm-up stop can be controlled within a time range in which the user is not easily uncomfortable, thereby avoiding excessive suppression of the warm-up stop to cause the cooling or heating efficiency to decrease.

[0064] In one embodiment, the embodiment provides a specific implementation of determining whether the average warm-up stop time or the average warm-up start time is within the preset comfortable time range:

[0065] When the air conditioner is in the cooling mode, it is determined whether the average temperature stop time is less than or equal to a first preset time length. If not, it is determined that the average temperature stop time is not in the preset comfortable time range.

[0066] When the air conditioner is in the heating mode, it is determined whether the average temperature start time is greater than or equal to a second preset time length. If not, it is determined that the average temperature start time is not in the preset comfortable time range.

[0067] The first preset time length can be 10-20 minutes, and the preferred value is 15 minutes. When the air conditioner is in the cooling mode, if the average temperature stop time is within the first preset time length, the temperature fluctuation is not easily perceived, and the user is not easily uncomfortable. If the average temperature stop time is greater than the first preset time length, the user is easily uncomfortable, and it is determined that the average temperature stop time is not in the preset comfortable time range.

[0068] The first preset time length can be 30-50 minutes, and the preferred value is 40 minutes. When the air conditioner is in the heating mode, if the average temperature start time is greater than or equal to the second preset time length, the temperature fluctuation is not easily perceived, and the user is not easily uncomfortable. If the average temperature start time is less than the second preset time length, the user is easily uncomfortable, and it is determined that the average temperature start time is not in the preset comfortable time range.

[0069] By determining whether the average temperature stop time of the first few times is less than or equal to the first preset time length in the cooling mode, and whether the average temperature start time of the first few times is greater than or equal to the second preset time length in the heating mode, it can be determined whether the user is uncomfortable in the first few temperature stop control, thereby providing basic data for suppressing the temperature stop control.

[0070] In an embodiment, the embodiment provides a specific implementation of controlling the bypass valve to open when the average temperature stop time or the average temperature start time is not in the preset comfortable time range:

[0071] When the average temperature stop time is greater than the first preset time length, or the average temperature start time is less than the second preset time length, it is monitored whether the operating frequency of the compressor reaches the minimum frequency. When the operating frequency of the compressor reaches the minimum frequency, the bypass valve is controlled to open.

[0072] When the average temperature stop time is greater than the first preset time length in the cooling mode, the average temperature stop time is not in the preset comfortable time range, i.e., the user is uncomfortable in the previous temperature stop control. It is monitored whether the operating frequency of the compressor reaches the minimum frequency. If so, the bypass valve is controlled to open, i.e., the temperature stop control can be effectively suppressed, the user's comfort can be improved, and excessive suppression of the temperature stop control can be avoided.

[0073] In the heating mode, when the average time to temperature start-up is less than a second preset time length, the average time to temperature start-up is not in the preset comfortable time range, that is, the user has an uncomfortable feeling in the previous temperature stop control, whether the operating frequency of the compressor reaches the minimum frequency is monitored, and if so, the bypass valve is opened to avoid the user having an uncomfortable feeling.

[0074] In an embodiment, the method provided by the embodiment further includes:

[0075] When the bypass valve is opened, the opening time of the bypass valve is timed;

[0076] When the opening time of the bypass valve reaches a third preset time length, the bypass valve is closed, and the number of temperature stop times and the opening time of the bypass valve are reset to zero.

[0077] The third preset time length can be 100-140 min, and is preferably 120 min.

[0078] After the bypass valve is opened, the opening time of the bypass valve is counted based on the timer; because the load changes (such as changes in outdoor ambient temperature, indoor solar radiation, or the number of indoor personnel) as time goes on after the bypass valve is opened, the balance point of the load and the air conditioner capacity changes, and therefore it is necessary to re-determine whether to open the bypass valve, switch the bypass valve from the open state to the closed state, and reset the number of temperature stop times and the opening time of the bypass valve. On the premise of not affecting comfort, the bypass valve is closed, so as to reduce the efficiency reduction time to the shortest time.

[0079] In an embodiment, the method provided by the embodiment further includes:

[0080] When the bypass valve is opened, the discharge temperature of the compressor is detected, and when the discharge temperature of the compressor exceeds a preset temperature, the bypass valve is controlled to be closed.

[0081] The preset temperature can be 90-110℃, and is preferably 100℃.

[0082] The bypass valve may cause risks such as an increase in the discharge temperature after being opened. By monitoring the discharge temperature of the compressor after the bypass valve is opened, the bypass valve is controlled to be closed to return to normal control when the discharge temperature of the compressor is high, so as to avoid the discharge temperature of the compressor being too high, and improve the stability of the operation of the air conditioner.

[0083] In an embodiment, the method provided by the embodiment further includes:

[0084] When the bypass valve is opened, the compression ratio of the compressor is detected, and when the compression ratio is less than a preset compression ratio threshold, the bypass valve is controlled to be closed.

[0085] The bypass valve opening can also cause the compression ratio of the compressor to decrease. By monitoring the compression ratio of the compressor after the bypass valve is opened, the bypass valve is controlled to be closed to return to normal control when the compression ratio is less than a preset compression ratio threshold, so as to avoid insufficient compression ratio of the compressor and improve the reliability of the air conditioner operation.

[0086] In an embodiment, the method provided by the embodiment further includes:

[0087] When the bypass valve is opened, the operation mode of the air conditioner is detected, and the bypass valve is controlled to be closed when the operation mode becomes a defrosting mode or an oil return mode.

[0088] The bypass valve opening can also cause the defrosting time to be prolonged and other risks. By monitoring the operation mode of the air conditioner after the bypass valve is opened and controlling the bypass valve to be closed to return to normal control when the operation mode enters the defrosting mode or the oil return mode, the problem of prolonged defrosting time can be avoided, and the stability of the air conditioner operation is improved.

[0089] The to-warm shutdown suppression control method of the air conditioner provided by the embodiment can control the occurrence period of to-warm shutdown within a range in which the user is not easily uncomfortable, and can avoid excessive suppression of to-warm shutdown, thereby minimizing the reduction in efficiency.

[0090] Corresponding to the to-warm shutdown suppression control method of the air conditioner provided by the above embodiment, the embodiment provides an example of applying the to-warm shutdown suppression control method of the air conditioner, which can be specifically executed according to the following steps:

[0091] Step 1, referring to the to-warm shutdown suppression control flowchart in the refrigeration mode as shown in Figure 3 , the air conditioner in the refrigeration operation is judged whether to enter to-warm shutdown, if yes, the to-warm shutdown number is +1;

[0092] If no, return to execute the step of judging whether to enter to-warm shutdown, if yes, calculate the to-warm shutdown average time when entering to-warm shutdown for the last two times;

[0093] If no, judge whether the compressor frequency is the lowest frequency;

[0094] When the compressor frequency is the lowest frequency, the bypass valve is controlled to be opened, and the opening time of the bypass valve is timed;

[0095] If yes, the bypass valve is controlled to be closed, the to-warm shutdown number and the opening time of the bypass valve are cleared, and the step of judging whether to enter to-warm shutdown is executed.

[0096] Step 2, see as Figure 4 The air conditioner is in heating operation, and it is judged whether to enter into the warm stop. If yes, the number of times of entering into the warm stop is +1.

[0097] It is judged whether the number of times of entering into the warm stop is greater than or equal to 3. If no, it returns to execute the step of judging whether to enter into the warm stop. If yes, the average time of the warm start when entering into the warm stop for the previous two times is calculated.

[0098] It is judged whether the average time of the warm start is greater than or equal to 40 min. If yes, it returns to execute the step of judging whether to enter into the warm stop. If no, it is judged whether the compressor frequency is the lowest frequency.

[0099] When the compressor frequency is the lowest frequency, the bypass valve is controlled to be opened. The opening time of the bypass valve is timed.

[0100] It is judged whether the opening time of the bypass valve is greater than or equal to 2 h. If yes, the bypass valve is controlled to be closed. The number of times of entering into the warm stop and the opening time of the bypass valve are cleared, and it returns to execute the step of judging whether to enter into the warm stop.
