DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] According to an embodiment of the present invention, a control method for an air conditioner is provided, wherein the air conditioner comprises an air source heat pump system and a water side system; the air source heat pump system and the water side system perform heat exchange through a heat exchanger, and the heat exchanger is specifically Figure 3 The second heat exchanger 7 in the air source heat pump system has a compressor.

[0031] The system structure of the air conditioner is as follows Figure 3 As shown, the air source heat pump system includes a compressor 1, a four-way valve 2, a first heat exchanger 3, a fan 4, a first throttle valve 5, a second throttle valve 6, a second heat exchanger 7, and a gas-liquid separator 8. When the air conditioner is in heating operation, the first heat exchanger 3 is an evaporator, and the high-temperature refrigerant and the water side system are heat exchanged through the second heat exchanger 7, thereby transferring heat to the user side. The second heat exchanger 7 can be a plate heat exchanger. Specifically, after the high-temperature and high-pressure refrigerant discharged from the compressor 1 passes through the four-way valve 2, it is heat exchanged with the cold water flowing into the second heat exchanger 7 in the second heat exchanger 7, and then the hot water is supplied to the user side. The cooled refrigerant passes through the second throttle valve 6, the first throttle valve 5, the first heat exchanger 3, the four-way valve 2, and the gas-liquid separator 8 in turn and returns to the compressor. In some embodiments, in the heating mode, the first throttle valve 5 is throttled and depressurized, and the second throttle valve 6 is in a fully open state; in the cooling mode, the first throttle valve 5 is in a fully open state, and the second throttle valve 6 is throttled and depressurized.

[0032] The operation mode of the air conditioner includes a comfort mode; the comfort mode is used to adjust the noise generated when the air conditioner is running.

[0033] The air conditioner will generate noise during operation. Although the noise generated by the air conditioner will not be higher than the nominal noise value, it may be near the nominal noise value for a long time, that is, the air conditioner will generate a lot of noise for a long time. Since the unit frequency of the air conditioner during cooling is not too high, the air conditioner will not generate a lot of noise; in heating mode, it will generate a lot of noise due to the high operating frequency. Therefore, the air conditioner of this solution has a comfort mode. When the air conditioner is running in heating mode, if the user thinks that the noise generated by the air conditioner is too loud and needs to reduce the noise, the user can turn on the comfort mode to reduce the noise generated by the air conditioner without affecting the indoor comfort, thereby improving the user's comfort.

[0034] like Figure 1 The flowchart of an embodiment of the method of the present invention is shown in FIG. The air conditioner control method may include: steps S110 to S140.

[0035] In step S110, during the operation of the air conditioner, if the air conditioner receives an instruction to turn on the comfort mode, the indoor ambient temperature, the outlet water temperature of the heat exchanger, and the indoor noise value are obtained.

[0036] A noise collector is installed in the indoor unit of the air conditioner to collect indoor noise, which may include indoor noise when the air conditioner is stopped and indoor noise when the air conditioner is running. The outlet water temperature of the heat exchanger is collected by the outlet water temperature sensing package 10.

[0037] In step S120, after the indoor ambient temperature reaches the set indoor ambient temperature, the air conditioner is controlled to turn on the comfort mode, and it is determined whether to adjust the noise emitted by the air conditioner according to the indoor noise value.

[0038] After the air conditioner receives the instruction to turn on the comfort mode from the user, it will not directly enter the comfort mode, but first determine whether the indoor ambient temperature has reached the set indoor ambient temperature, thereby determining whether the air conditioner should turn on the comfort mode. The set indoor ambient temperature is the target indoor temperature set by the user. When the indoor ambient temperature has not yet reached the set indoor ambient temperature, the air conditioner may be in the state of just being turned on or just finishing defrosting. In order to ensure the comfort of the indoor environment, it is necessary to increase the operating frequency as soon as possible to improve the heating capacity. Therefore, the air conditioner will not enter the comfort mode temporarily, and will turn on the comfort mode after the indoor ambient temperature reaches the set indoor ambient temperature.

[0039] Optionally, whether to turn on the comfort mode can be determined based on the difference between the indoor ambient temperature and the set indoor ambient temperature. Specifically, the difference between the indoor ambient temperature and the set indoor ambient temperature is ΔT. If ΔT ≥ the set value T1, the air conditioner does not turn on the comfort mode, and the unit operates at a higher frequency for heating; if ΔT < T1, the air conditioner turns on the comfort mode. T1 can be set to 5°C or 10°C. When the outdoor temperature is high, T1 is 10°C, and when the outdoor temperature is low, T1 is 5°C.

[0040] In some embodiments, in step S120, the specific process of determining whether to adjust the noise emitted by the air conditioner according to the indoor noise value includes: recording the difference between the indoor noise value and the set noise value as the noise difference, and judging the size relationship between the noise difference and the set noise difference; if the noise difference is greater than or equal to the set noise difference, determining to adjust the noise emitted by the air conditioner; if the noise difference is less than the set noise difference, determining not to adjust the noise emitted by the air conditioner.

[0041] The noise value is set to the indoor noise value when the air conditioner stops running. For example, when the air conditioner is not turned on, the indoor noise will be collected to obtain a set of multiple noise values. The noise values ​​that suddenly increase are removed from the set, and the noise values ​​with relatively stable fluctuations and longer duration are retained. The average value of the set is used as the set noise value.

[0042] After the air conditioner enters the comfort mode, it will first determine whether it needs to adjust the indoor noise. The specific judgment process is that the difference between the indoor noise value and the set noise value is ΔL. If ΔL<L1, it is considered that the noise generated by the air conditioner is relatively small, and the ambient noise at this time is closer to the ambient noise when the air conditioner is not running, so there is no need to adjust the noise emitted by the air conditioner; if ΔL≥L1, it is considered that the noise generated by the air conditioner is relatively large and has affected the indoor comfort, and the noise emitted by the air conditioner needs to be adjusted.

[0043] At step S130, if it is determined to adjust the noise emitted by the air conditioner, the operating frequency of the compressor is controlled and the air conditioner exits the comfort mode according to the indoor noise value and the outlet water temperature, thereby reducing the noise emitted by the air conditioner and keeping the indoor noise within a smaller range, thereby avoiding excessive noise that affects the user experience.

[0044] In some implementations, in step 130, the specific process of controlling the operating frequency of the compressor and the air conditioner exiting the comfort mode according to the indoor noise value and the outlet water temperature includes: steps S210 to S230.

[0045] Step S210, recording the difference between the outlet water temperature and the set outlet water temperature as a temperature difference value, and determining the magnitude relationship between the temperature difference value and the set temperature difference value.

[0046] Step S220: if the temperature difference is greater than or equal to the set temperature difference, the operating frequency of the compressor is reduced; after a preset time, the operating frequency of the compressor is controlled according to the temperature difference and the indoor noise value.

[0047] In some embodiments, in step S220, the specific process of controlling the operating frequency of the compressor according to the temperature difference value and the indoor noise value includes: recording the difference between the indoor noise value and the set noise value as the noise difference value, and judging the size relationship between the noise difference value and the set noise difference value; if the noise difference value is less than the set noise difference value, keeping the operating frequency of the compressor unchanged; if the noise difference value is greater than or equal to the set noise difference value, judging the size of the temperature difference value; if the temperature difference value is within a first range, reducing the operating frequency of the compressor by a first adjustment amount; if the temperature difference value is within a second range, reducing the operating frequency of the compressor by a second adjustment amount; wherein, the first range>the second range, and the first adjustment amount>the second adjustment amount.

[0048] In the process of controlling the operating frequency of the compressor, the operating frequency is first reduced by the first adjustment amount. If the noise difference is less than the set noise difference, it is considered that the indoor noise is effectively controlled and will not have a significant impact on comfort. Therefore, the operating frequency of the compressor can be kept unchanged. If the noise difference is ≥ the set noise difference after the operating frequency is reduced for the first time, it is necessary to continue to reduce the operating frequency of the compressor to reduce the noise. Multiple temperature difference ranges can be set, and each temperature difference range corresponds to an operating frequency adjustment amount. The larger the temperature difference range, the larger the adjustment amount. Specifically, if the temperature difference is in a larger first range, even if the operating frequency is reduced too much, it can still ensure that the outlet water temperature meets the requirements. Therefore, the operating frequency is reduced by a larger first adjustment amount; if the temperature difference is in a smaller second range, if the operating frequency is reduced too much at this time, the outlet water temperature may be lower than the required temperature, causing discomfort in the room, so the operating frequency is reduced by a smaller second adjustment amount. After a period of time after the compressor operating frequency is reduced, the compressor operating frequency is controlled again according to the temperature difference and the indoor noise value.

[0049] By determining the reduction in operating frequency based on the size of the temperature difference, it is ensured that the indoor temperature will not change significantly during the noise adjustment process to affect comfort, so that users perceive less noise and improve user experience.

[0050] Step S230: If the temperature difference is less than the set temperature difference, the air conditioner is controlled to exit the comfort mode.

[0051] When the air conditioner is running, the noise from the indoor side is too loud. One possible reason is that the sound insulation of the actual use environment of the air conditioner is poor, causing the noise transmitted to the room by the air conditioner to exceed the nominal noise value of the air conditioner. For example, the interior decoration does not use sound insulation materials, and the room does not have a sound insulation layer. The nominal noise value of the air conditioner is the maximum noise value that people can hear generated by the air conditioner as a whole.

[0052] Therefore, after determining the noise generated by adjusting the air conditioner, first determine whether the use environment of the air conditioner is poor based on the outlet water temperature. The set outlet water temperature corresponds to the set indoor ambient temperature. When the outlet water temperature reaches the set outlet water temperature, it is considered that the indoor ambient temperature can reach the set indoor ambient temperature. Specifically, the difference Δt between the outlet water temperature and the set outlet water temperature, if Δt≥the set value t1, that is, the outlet water temperature is higher than the set outlet water temperature, then reducing the unit operating frequency can still ensure that the indoor temperature reaches the target temperature, so reducing the compressor operating frequency can reduce the operating frequency by the first adjustment amount, and then continue to control the operating frequency; if Δt<t1, it is considered that the nominal noise value of the air conditioner does not meet the user's usage, or the noise reduction effect in the user's room is poor. At this time, the situation can be reflected to the user or relevant technical personnel, and the air conditioner can be controlled to exit the comfort mode.

[0053] At step S140, if it is determined that the noise emitted by the air conditioner is not to be adjusted, the operating frequency of the compressor is controlled according to the outlet water temperature, so as to avoid the air conditioner being shut down due to excessive load, ensure the normal operation of the air conditioner, and improve the stability of the air conditioner.

[0054] In some embodiments, in step S140, the specific process of controlling the operating frequency of the compressor according to the outlet water temperature includes: recording the difference between the outlet water temperature and the set outlet water temperature as a temperature difference value, and judging the relationship between the temperature difference value and the set temperature difference value; if the temperature difference value is greater than or equal to the set temperature difference value, reducing the operating frequency of the compressor; if the temperature difference value is less than the set temperature difference value, keeping the operating frequency of the compressor unchanged.

[0055] After turning on the comfort mode, if it is determined not to adjust the noise emitted by the air conditioner, the unit is controlled only according to the outlet water temperature to ensure normal and stable operation of the unit. Specifically, the difference between the outlet water temperature and the set outlet water temperature Δt, if Δt≥ the set value t1, it is considered that the unit power is large and there is a risk of power protection shutdown, and the unit load is too high. At this time, the operating frequency of the compressor is reduced to reduce the unit load and ensure the normal operation of the unit. After Δt<t1, the operating frequency of the compressor is kept unchanged.

[0056] In some embodiments, the air source heat pump system further comprises an electronic expansion valve and a fan. The control method further comprises: when reducing the operating frequency of the compressor, also reducing the opening of the electronic expansion valve and the rotation speed of the external fan.

[0057] In order to maintain the superheat of the unit, when reducing the operating frequency of the compressor, it is also necessary to reduce the opening of the electronic expansion valve and the speed of the fan at the same time, so as to maintain the room temperature without a large change. Figure 3 The first throttle valve 5 and the second throttle valve 6 in the external fan are Figure 3 The fan 4 in.

[0058] Figure 4 It is a schematic diagram of the flow chart of the comfort mode of the air conditioner of the present invention, as shown in Figure 4 As shown, the process includes:

[0059] Step 1: After the air conditioner is turned on, the unit is set to comfort mode to determine whether T 目标环温 -T 实际环温 <α. If T 目标环温 -T 实际环温 <α, the unit enters comfort mode and executes step 2.

[0060] Step 2: Determine T 出水温度 -T 目标出水温度= the size relationship between c and γ, and the size relationship between (βb-βa) and β*. γ is the set temperature difference, β* is the set noise difference, βa is the indoor noise when the air conditioner is not turned on, and βb is the indoor noise at this time. If βb-βa<β*, execute step 3, if βb-βa≥β*, execute step 4.

[0061] Step 3, determine whether c≥γ and c<0. If c≥γ, reduce the unit frequency, reduce the opening of the electronic expansion valve, and lower the windshield until c<γ and then execute step 2; if c<0, control the unit to increase the frequency and then execute step 2; if c<0, and c shows an increasing trend within the Xmin time, directly execute step 2.

[0062] Step 4, determine whether c≥γ and c<0. If c<0, feedback to the technician that the noise limit of the air conditioner does not meet the user's usage or the noise reduction effect of the user's room is poor, and exit the comfort mode; if c≥γ, reduce the unit frequency by dHZ. After Ymin time, if it is detected that βb-βa≥β*, and γ-e≤c<γ-e+1, and e<y, continue to reduce the unit frequency, and the reduction amount corresponds to the range of c, the reduction amount is d-eHZ, γ-e is the lower limit of the range, and γ-e+1 is the upper limit of the range. Then execute step 2.

[0063] By adopting the technical solution of this embodiment, the air conditioner has a comfort mode for adjusting the noise generated by the operation of the air conditioner; when the air conditioner is running, if the air conditioner receives an instruction to turn on the comfort mode, the air conditioner turns on the comfort mode after the indoor ambient temperature reaches the set indoor ambient temperature, and determines whether to adjust the noise emitted by the air conditioner according to the indoor noise value; if it is determined to adjust the noise emitted by the air conditioner, the operating frequency of the compressor and the operating mode of the air conditioner are controlled according to the indoor noise value and the outlet water temperature; if it is determined not to adjust the noise emitted by the air conditioner, the operating frequency of the compressor is controlled according to the outlet water temperature. Thus, by adjusting the noise emitted by the air conditioner according to the indoor noise value and the outlet water temperature of the air conditioner, the noise received indoors is reduced without affecting the indoor temperature, thereby improving the user experience.

[0064] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method for an air conditioner is also provided. The air conditioner comprises an air source heat pump system and a water side system; the air source heat pump system and the water side system perform heat exchange through a heat exchanger, and the heat exchanger is specifically Figure 3 The second heat exchanger 7 in the air source heat pump system has a compressor.

[0065] The system structure of the air conditioner is as follows Figure 3As shown, the air source heat pump system includes a compressor 1, a four-way valve 2, a first heat exchanger 3, a fan 4, a first throttle valve 5, a second throttle valve 6, a second heat exchanger 7, and a gas-liquid separator 8. When the air conditioner is in heating operation, the first heat exchanger 3 is an evaporator, and the high-temperature refrigerant and the water side system are heat exchanged through the second heat exchanger 7, thereby transferring heat to the user side. The second heat exchanger 7 can be a plate heat exchanger. Specifically, after the high-temperature and high-pressure refrigerant discharged from the compressor 1 passes through the four-way valve 2, it is heat exchanged with the cold water flowing into the second heat exchanger 7 in the second heat exchanger 7, and then the hot water is supplied to the user side. The cooled refrigerant passes through the second throttle valve 6, the first throttle valve 5, the first heat exchanger 3, the four-way valve 2, and the gas-liquid separator 8 in turn and returns to the compressor. In some embodiments, in the heating mode, the first throttle valve 5 is throttled and depressurized, and the second throttle valve 6 is in a fully open state; in the cooling mode, the first throttle valve 5 is in a fully open state, and the second throttle valve 6 is throttled and depressurized.

[0066] The operation mode of the air conditioner includes a comfort mode; the comfort mode is used to adjust the noise generated when the air conditioner is running.

[0067] The air conditioner will generate noise during operation. Although the noise generated by the air conditioner will not be higher than the nominal noise value, it may be near the nominal noise value for a long time, that is, the air conditioner will generate a lot of noise for a long time. Since the unit frequency of the air conditioner during cooling is not too high, the air conditioner will not generate a lot of noise; in heating mode, it will generate a lot of noise due to the high operating frequency. Therefore, the air conditioner of this solution has a comfort mode. When the air conditioner is running in heating mode, if the user thinks that the noise generated by the air conditioner is too loud and needs to reduce the noise, the user can turn on the comfort mode to reduce the noise generated by the air conditioner without affecting the indoor comfort, thereby improving the user's comfort.

[0068] See also Figure 2 The schematic diagram of the structure of an embodiment of the device of the present invention is shown. The control device of the air conditioner may include: an acquisition unit 102 and a control unit 104.

[0069] The acquisition unit 102 is configured to acquire the indoor ambient temperature, the outlet water temperature of the heat exchanger, and the indoor noise value during the operation of the air conditioner if the air conditioner receives an instruction to turn on the comfort mode. The specific functions and processing of the acquisition unit 102 refer to step S110.

[0070] A noise collector is installed in the indoor unit of the air conditioner to collect indoor noise, which may include indoor noise when the air conditioner is stopped and indoor noise when the air conditioner is running. The outlet water temperature of the heat exchanger is collected by the outlet water temperature sensing package 10.

[0071] The control unit 104 is configured to control the air conditioner to turn on the comfort mode after the indoor ambient temperature reaches the set indoor ambient temperature, and determine whether to adjust the noise emitted by the air conditioner according to the indoor noise value. The specific functions and processing of the control unit 104 refer to step S120.

[0072] After the air conditioner receives the instruction to turn on the comfort mode from the user, it will not directly enter the comfort mode, but first determine whether the indoor ambient temperature has reached the set indoor ambient temperature, thereby determining whether the air conditioner should turn on the comfort mode. The set indoor ambient temperature is the target indoor temperature set by the user. When the indoor ambient temperature has not yet reached the set indoor ambient temperature, the air conditioner may be in the state of just being turned on or just finishing defrosting. In order to ensure the comfort of the indoor environment, it is necessary to increase the operating frequency as soon as possible to improve the heating capacity. Therefore, the air conditioner will not enter the comfort mode temporarily, and will turn on the comfort mode after the indoor ambient temperature reaches the set indoor ambient temperature.

[0073] Optionally, whether to turn on the comfort mode can be determined based on the difference between the indoor ambient temperature and the set indoor ambient temperature. Specifically, the difference between the indoor ambient temperature and the set indoor ambient temperature is ΔT. If ΔT ≥ the set value T1, the air conditioner does not turn on the comfort mode, and the unit operates at a higher frequency for heating; if ΔT < T1, the air conditioner turns on the comfort mode. T1 can be set to 5°C or 10°C. When the outdoor temperature is high, T1 is 10°C, and when the outdoor temperature is low, T1 is 5°C.

[0074] In some embodiments, the control unit 104 determines whether to adjust the noise emitted by the air conditioner according to the indoor noise value. The specific process includes: recording the difference between the indoor noise value and the set noise value as the noise difference, and judging the size relationship between the noise difference and the set noise difference; if the noise difference is greater than or equal to the set noise difference, determining to adjust the noise emitted by the air conditioner; if the noise difference is less than the set noise difference, determining not to adjust the noise emitted by the air conditioner.

[0075] The noise value is set to the indoor noise value when the air conditioner stops running. For example, when the air conditioner is not turned on, the indoor noise will be collected to obtain a set of multiple noise values. The noise values ​​that suddenly increase are removed from the set, and the noise values ​​with relatively stable fluctuations and longer duration are retained. The average value of the set is used as the set noise value.

[0076] After the air conditioner enters the comfort mode, it will first determine whether it needs to adjust the indoor noise. The specific judgment process is that the difference between the indoor noise value and the set noise value is ΔL. If ΔL<L1, it is considered that the noise generated by the air conditioner is relatively small, and the ambient noise at this time is closer to the ambient noise when the air conditioner is not running, so there is no need to adjust the noise emitted by the air conditioner; if ΔL≥L1, it is considered that the noise generated by the air conditioner is relatively large and has affected the indoor comfort, and the noise emitted by the air conditioner needs to be adjusted.

[0077] The control unit 104 is further configured to control the operating frequency of the compressor and the air conditioner to exit the comfort mode according to the indoor noise value and the outlet water temperature if it is determined to adjust the noise emitted by the air conditioner. This reduces the noise emitted by the air conditioner, keeps the indoor noise within a smaller range, and avoids excessive noise affecting the user experience. The specific functions and processing of the control unit 104 refer to step S130.

[0078] In some implementations, the control unit 104 controls the operating frequency of the compressor and the specific process of the air conditioner exiting the comfort mode according to the indoor noise value and the outlet water temperature, including:

[0079] The control unit 104 is further configured to record the difference between the outlet water temperature and the set outlet water temperature as a temperature difference value, and determine the magnitude relationship between the temperature difference value and the set temperature difference value. The specific functions and processing of the control unit 104 refer to step S210.

[0080] The control unit 104 is further configured to reduce the operating frequency of the compressor if the temperature difference is greater than or equal to the set temperature difference; and control the operating frequency of the compressor according to the temperature difference and the indoor noise value after a preset time. The specific functions and processing of the control unit 104 refer to step S220.

[0081] In some embodiments, the control unit 104 controls the specific process of controlling the operating frequency of the compressor according to the temperature difference value and the indoor noise value, including: recording the difference between the indoor noise value and the set noise value as the noise difference value, and judging the size relationship between the noise difference value and the set noise difference value; if the noise difference value is less than the set noise difference value, keeping the operating frequency of the compressor unchanged; if the noise difference value is greater than or equal to the set noise difference value, judging the size of the temperature difference value; if the temperature difference value is within a first range, reducing the operating frequency of the compressor by a first adjustment amount; if the temperature difference value is within a second range, reducing the operating frequency of the compressor by a second adjustment amount; wherein, the first range>the second range, and the first adjustment amount>the second adjustment amount.

[0082] In the process of controlling the operating frequency of the compressor, the operating frequency is first reduced by the first adjustment amount. If the noise difference is less than the set noise difference, it is considered that the indoor noise is effectively controlled and will not have a significant impact on comfort. Therefore, the operating frequency of the compressor can be kept unchanged. If the noise difference is ≥ the set noise difference after the operating frequency is reduced for the first time, it is necessary to continue to reduce the operating frequency of the compressor to reduce the noise. Multiple temperature difference ranges can be set, and each temperature difference range corresponds to an operating frequency adjustment amount. The larger the temperature difference range, the larger the adjustment amount. Specifically, if the temperature difference is in a larger first range, even if the operating frequency is reduced too much, it can still ensure that the outlet water temperature meets the requirements. Therefore, the operating frequency is reduced by a larger first adjustment amount; if the temperature difference is in a smaller second range, if the operating frequency is reduced too much at this time, the outlet water temperature may be lower than the required temperature, causing discomfort in the room, so the operating frequency is reduced by a smaller second adjustment amount. After a period of time after the compressor operating frequency is reduced, the compressor operating frequency is controlled again according to the temperature difference and the indoor noise value.

[0083] By determining the reduction in operating frequency based on the size of the temperature difference, it is ensured that the indoor temperature will not change significantly during the noise adjustment process to affect comfort, so that users perceive less noise and improve user experience.

[0084] The control unit 104 is further configured to control the air conditioner to exit the comfort mode if the temperature difference is less than a set temperature difference. The specific functions and processing of the control unit 104 refer to step S230.

[0085] When the air conditioner is running, the noise from the indoor side is too loud. One possible reason is that the sound insulation of the actual use environment of the air conditioner is poor, causing the noise transmitted to the room by the air conditioner to exceed the nominal noise value of the air conditioner. For example, the interior decoration does not use sound insulation materials, and the room does not have a sound insulation layer. The nominal noise value of the air conditioner is the maximum noise value that people can hear generated by the air conditioner as a whole.

[0086] Therefore, after determining the noise generated by adjusting the air conditioner, first determine whether the use environment of the air conditioner is poor based on the outlet water temperature. The set outlet water temperature corresponds to the set indoor ambient temperature. When the outlet water temperature reaches the set outlet water temperature, it is considered that the indoor ambient temperature can reach the set indoor ambient temperature. Specifically, the difference Δt between the outlet water temperature and the set outlet water temperature, if Δt≥the set value t1, that is, the outlet water temperature is higher than the set outlet water temperature, then reducing the unit operating frequency can still ensure that the indoor temperature reaches the target temperature, so reducing the compressor operating frequency can reduce the operating frequency by the first adjustment amount, and then continue to control the operating frequency; if Δt<t1, it is considered that the nominal noise value of the air conditioner does not meet the user's usage, or the noise reduction effect in the user's room is poor. At this time, the situation can be reflected to the user or relevant technical personnel, and the air conditioner can be controlled to exit the comfort mode.

[0087] The control unit 104 is further configured to control the operating frequency of the compressor according to the outlet water temperature if it is determined that the noise emitted by the air conditioner is not to be adjusted. This avoids the air conditioner from being shut down due to excessive load, ensures the normal operation of the air conditioner, and improves the stability of the air conditioner. The specific functions and processing of the control unit 104 refer to step S140.

[0088] In some embodiments, the control unit 104 controls the specific process of controlling the operating frequency of the compressor according to the outlet water temperature, including: recording the difference between the outlet water temperature and the set outlet water temperature as the temperature difference value, and judging the relationship between the temperature difference value and the set temperature difference value; if the temperature difference value is greater than or equal to the set temperature difference value, reducing the operating frequency of the compressor; if the temperature difference value is less than the set temperature difference value, keeping the operating frequency of the compressor unchanged.

[0089] After turning on the comfort mode, if it is determined not to adjust the noise emitted by the air conditioner, the unit is controlled only according to the outlet water temperature to ensure normal and stable operation of the unit. Specifically, the difference between the outlet water temperature and the set outlet water temperature Δt, if Δt≥ the set value t1, it is considered that the unit power is large and there is a risk of power protection shutdown, and the unit load is too high. At this time, the operating frequency of the compressor is reduced to reduce the unit load and ensure the normal operation of the unit. After Δt<t1, the operating frequency of the compressor is kept unchanged.

[0090] In some embodiments, the air source heat pump system further comprises an electronic expansion valve and a fan. The control unit 104 is further configured to: when reducing the operating frequency of the compressor, also reduce the opening of the electronic expansion valve and the rotation speed of the external fan.

[0091] In order to maintain the superheat of the unit, when reducing the operating frequency of the compressor, it is also necessary to reduce the opening of the electronic expansion valve and the speed of the fan at the same time, so as to maintain the room temperature without a large change. Figure 3 The first throttle valve 5 and the second throttle valve 6 in the external fan are Figure 3 The fan 4 in.

[0092] Figure 4 It is a schematic diagram of the flow chart of the comfort mode of the air conditioner of the present invention, as shown in Figure 4 As shown, the process includes:

[0093] Step 1: After the air conditioner is turned on, the unit is set to comfort mode to determine whether T 目标环温 -T 实际环温 <α. If T 目标环温 -T 实际环温 <α, the unit enters comfort mode and executes step 2.

[0094] Step 2: Determine T 出水温度 -T目标出水温度 = the size relationship between c and γ, and the size relationship between (βb-βa) and β*. γ is the set temperature difference, β* is the set noise difference, βa is the indoor noise when the air conditioner is not turned on, and βb is the indoor noise at this time. If βb-βa<β*, execute step 3, if βb-βa≥β*, execute step 4.

[0095] Step 3, determine whether c≥γ and c<0. If c≥γ, reduce the unit frequency, reduce the opening of the electronic expansion valve, and lower the windshield until c<γ and then execute step 2; if c<0, control the unit to increase the frequency and then execute step 2; if c<0, and c shows an increasing trend within the Xmin time, directly execute step 2.

[0096] Step 4, determine whether c≥γ and c<0. If c<0, feedback to the technician that the noise limit of the air conditioner does not meet the user's usage or the noise reduction effect of the user's room is poor, and exit the comfort mode; if c≥γ, reduce the unit frequency by dHZ. After Ymin time, if it is detected that βb-βa≥β*, and γ-e≤c<γ-e+1, and e<y, continue to reduce the unit frequency, and the reduction amount corresponds to the range of c, the reduction amount is d-eHZ, γ-e is the lower limit of the range, and γ-e+1 is the upper limit of the range. Then execute step 2.
