[0063] It should be understood that the specific embodiments described herein are merely illustrative of the present application and do not limit the present application.

[0064] Reference Figure 1 , Figure 1 is a structure schematic view of a multi-connected air conditioner of a hardware running environment related to the embodiment scheme of the present application.

The network interface 1004 can optionally include a standard wired interface, a wireless interface (such as a wireless fidelity (Wi-Fi) interface). The memory 1005 can be a high-speed random access memory (RAM), and can also be a stable non-volatile memory (NVM), such as a disk memory. The memory 1005 can also be a storage device independent of the aforementioned processor 1001.

[0066] Those skilled in the art can understand that Figure 1 The structure shown in the figure does not constitute a limitation on the multi-split air conditioner, and can include more or fewer components than the figure, or combine certain components, or different component arrangements.

[0067] As Figure 1 As shown, the memory 1005 as a storage medium can include an operating system, a network communication module, a user interface module, and an air conditioner control program.

[0068] In Figure 1 As shown in the multi-split air conditioner, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the multi-split air conditioner of the present application can be arranged in the multi-split air conditioner, and the multi-split air conditioner calls the air conditioner control program stored in the memory 1005 through the processor 1001, and executes the air conditioner control method provided by the embodiment of the present application.

[0069] The embodiment of the present application provides an air conditioner control method, which refers to Figure 2 , Figure 2 The flowchart of a first embodiment of an air conditioner control method of the present application.

[0070] In this embodiment, the air conditioner control method includes the following steps:

[0071] Step S10: When the air conditioner simultaneously exists heating and hot water demand, the water tank temperature of the hot water tank is obtained.

[0072] It should be noted that the execution subject of the embodiment can be the air conditioner device, which has functions of data processing, data communication and program running, and can be a controller of a multi-split air conditioner. Of course, it can also be other devices with similar functions, which are not limited in the embodiment. For the convenience of description, the controller of the multi-split air conditioner is taken as an example for description.

[0073] It should be noted that the air conditioner in the embodiment refers to a multi-split air conditioner, which is described in detail with reference to Figure 3 The multi-split air conditioner is an air conditioner with an outdoor unit connected to multiple indoor units, which can realize the function of adjusting air temperature, humidity, cleanliness and air flow rate in multiple rooms at the same time, including but not limited to cooling, heating and fresh air circulation modes.

[0074] It should be noted that the multi-split air conditioner in the embodiment includes an air conditioner outdoor unit, an air conditioner indoor unit and a hydraulic module, the outdoor unit is connected to each air conditioner indoor unit and the hydraulic module, the air conditioner outdoor unit includes a compressor, an outdoor heat exchanger and at least two reversing devices, the air conditioner indoor unit includes at least one indoor heat exchanger, and the hydraulic module is provided with a heating water tank at the end, wherein each reversing device is connected to the compressor and is mainly used to control the flow direction of refrigerant in the multi-split air conditioner. The reversing device can be a four-way valve or a three-way valve, which is not limited in the embodiment.

[0075] In addition, the air conditioner outdoor unit is provided with a throttling element between each air conditioner indoor unit and the hydraulic module. In the embodiment, the throttling element includes a first throttling element corresponding to the indoor heat exchanger and a second throttling element corresponding to the heating water tank. The throttling element includes an electronic expansion valve and a capillary tube, which is mainly taken as an example in the embodiment. The throttling element between the air conditioner outdoor unit and each air conditioner indoor unit and the hydraulic module can include a main road electronic expansion valve and a corresponding branch electronic expansion valve of each air conditioner indoor unit or hydraulic module, which is not limited in the embodiment.

[0076] It can be understood that when the air conditioner indoor unit of the multi-split air conditioner operates in heating mode, the refrigerant is compressed by the compressor to obtain high-temperature and high-pressure refrigerant. The high-temperature and high-pressure refrigerant is delivered to the indoor heat exchanger through the four-way valve for condensation and heat dissipation. After heat exchange with the indoor environment, the indoor heat exchanger obtains medium-temperature and high-pressure refrigerant, which is throttled by the electronic expansion valve and the main road capillary tube in the above to obtain low-temperature and medium-temperature refrigerant. The low-temperature and medium-temperature refrigerant is delivered to the outdoor heat exchanger for evaporation to obtain low-temperature and low-pressure refrigerant. Finally, the low-temperature and low-pressure refrigerant is returned to the compressor through the four-way valve to complete a single heating process.

[0077] When the multi-connected air conditioner has a heating water demand, the refrigerant is compressed by the compressor to obtain high-temperature and high-pressure refrigerant. The high-temperature and high-pressure refrigerant is delivered to the heating water tank through the four-way valve. The heating water tank acts as a condenser to make the outlet water temperature greater than the inlet water temperature after heat exchange with the water path in the heating water tank, thereby achieving heating. The refrigerant flows through the water path of the heating water tank to obtain medium-temperature and high-pressure refrigerant, which is then delivered to the outdoor heat exchanger through the electronic expansion valve and the main capillary throttling element in the foregoing to obtain low-pressure and medium-temperature refrigerant. Finally, the low-temperature and low-pressure refrigerant is returned to the compressor through the four-way valve to complete a single heating process.

[0078] It should be understood that the water tank temperature includes but is not limited to the middle temperature of the coil, the outlet temperature of the coil, and the water temperature in the water tank. The water tank temperature can be the average value between the water temperature at the upper part of the water tank and the water temperature at the lower part of the water tank. The middle temperature of the water tank coil refers to the refrigerant saturation temperature corresponding to the compressor discharge pressure. In this embodiment, the refrigerant saturation temperature is related to the refrigerant category, refrigerant pressure, and other factors. Its main functions are temperature control, heat exchange, and energy efficiency improvement. Considering that there is pressure loss when the refrigerant passes through various heat exchanger devices, and there is basically no pressure loss when the refrigerant is transmitted in the pipeline, the middle temperature of the coil of the heating water tank directly connected to the compressor refrigerant output end is used as the refrigerant saturation temperature corresponding to the compressor discharge pressure in this embodiment.

[0079] Step S20: determining the air conditioner control mode corresponding to the water tank temperature.

[0080] In this embodiment, different control modes of different throttling elements have different control logics. For example, for the control mode of the first throttling element corresponding to the indoor heat exchanger, there are two control modes. One is to adjust the opening degree of the first throttling element according to the opening degree corresponding to the outdoor environment temperature. The other is to determine the temperature difference value according to the middle temperature of the indoor heat exchanger with heating demand and the average value of the middle temperatures of the indoor heat exchangers with capacity demand, and adjust the opening degree of the first throttling element according to the opening degree corresponding to the temperature difference value.

[0081] For the control mode of the second throttling element corresponding to the heating water tank, whether the control mode of the second throttling element is automatic control or abnormal control is determined according to the middle temperature of the heating water tank coil, the water temperature of the water tank, and the outlet temperature of the coil. This embodiment does not make specific limitations.

[0082] Further, the determination of the air conditioner control mode corresponding to the water tank temperature comprises:

[0083] When the water tank temperature is in the first temperature interval, a first opening degree control mode is run to adjust the opening degree of the first throttling element.

[0084] when the water tank temperature is in a third temperature interval, running a second opening degree control mode to adjust the opening degree of the first throttling element, the minimum value of the third temperature interval being greater than the maximum value of the second temperature interval.

[0085] when the water tank temperature is in a third temperature interval, running a second opening degree control mode to adjust the opening degree of the first throttling element, the minimum value of the third temperature interval being greater than the maximum value of the second temperature interval.

[0086] In a specific implementation, the water tank temperature mentioned above mainly refers to the water tank water temperature, that is, the water tank water temperature Tw < TW1 ℃ is controlled in the first control mode; the water tank water temperature Tw > TW2 ℃ (42 ℃) is controlled in the second control mode; and the water tank water temperature 39 ℃ ≤ Tw ≤ 42 ℃ maintains the last control mode. When the multi-split air conditioner is powered on for the first time, the control mode 2 is executed. The first control mode refers to a control mode in which the heating water is given priority and the indoor unit in the heating state is in a standby state. The second control mode refers to a control mode in which the indoor unit in the heating state and the heating water are simultaneously operated.

[0087] TW1 ℃ can be 39 ℃, and TW2 ℃ can be 42 ℃, which are not limited in the embodiment.

[0088] Step S30: Adjusting the opening degree of the first throttling element and / or the second throttling element according to the air conditioner control mode.

[0089] It is worth noting that in the embodiment, the opening degree adjustment of the first throttling element and the second throttling element is independent and does not affect each other.

[0090] The embodiment adjusts the opening degree of the first throttling element corresponding to the indoor heat exchanger or the second throttling element corresponding to the hydraulic module according to the control mode of the multi-split air conditioner, so as to adjust the refrigerant flow direction ratio and the heating effect of the indoor heat exchanger or the hydraulic module, thereby avoiding the technical problem that the heating effect is poor when the multi-split air conditioner is simultaneously operated in the heating and heating water modes in the prior art, and improving the heating effect of the multi-split air conditioner.

[0091] Reference Figure 4 , Figure 4 is a flowchart of a second embodiment of the air conditioner control method.

[0092] Based on the first embodiment, in the embodiment, the step S30 comprises:

[0093] Step S301: Determining the opening degree change value of the second throttling element according to the middle portion temperature of the coil, the coil outlet temperature, and the water tank water temperature.

[0094] It should be noted that when the opening degree of the second throttling element corresponding to the water heating tank is controlled, the second throttling element is first controlled to be initialized to an initial opening degree and maintained for a certain period of time, and then enters an automatic control mode of the second throttling element, so as to stabilize the measured temperature and avoid frequent switching of the control mode.

[0095] Further, in order to avoid that the exhaust temperature of the compressor is too large to greatly affect the water tank heating, the opening degree change value of the second throttling element is determined according to the middle portion temperature of the coil, the outlet temperature of the coil and the water temperature of the water tank after the second throttling element is maintained at the initial opening degree for a period of time, including:

[0096] obtaining the exhaust temperature of the compressor;

[0097] when the exhaust temperature is greater than an exhaust temperature threshold, determining the opening degree change value of the second throttling element according to the exhaust temperature, the middle portion temperature of the coil, the outlet temperature of the coil and the water temperature of the water tank;

[0098] when the exhaust temperature is less than or equal to the exhaust temperature threshold, determining the opening degree change value of the second throttling element according to the middle portion temperature of the coil, the outlet temperature of the coil and the water temperature of the water tank.

[0099] It can be understood that the exhaust temperature of the compressor refers to the temperature of the refrigerant output end of the compressor. If the exhaust temperature is too high and the opening degree of the second throttling element is small, the temperature of the water tank may rapidly rise, thereby affecting the normal use of the user.

[0100] In a specific implementation, if the exhaust temperature is greater than a first temperature threshold for a continuous preset first period of time, the second throttling element is not allowed to be adjusted to be small; if the exhaust temperature is less than or equal to the first temperature threshold for a continuous preset first period of time, the second throttling element is allowed to be adjusted to be small; if the exhaust temperature is greater than a second temperature threshold for a continuous preset first period of time, the second throttling element immediately increases a preset opening degree, and then increases the preset opening degree every interval of a certain period of time, wherein the first temperature threshold is less than the second temperature threshold.

[0101] For example, if the exhaust temperature is greater than 95℃ for a continuous 10s, the second throttling element is not allowed to be adjusted to be small; if the exhaust temperature is less than or equal to 95℃ for a continuous 10s, the second throttling element is allowed to be adjusted to be small; if the exhaust temperature is greater than 100℃ for a continuous 10s, the second throttling element immediately increases 50B, and then increases 50B every 10s. The above values are for illustration only and can be adaptively modified, and the embodiment does not specifically limit this.

[0102] In addition, in the present embodiment and the following embodiments, when the hot water tank is in the hot water mode, the opening range of the corresponding second throttling element is 120-480B, and the exhaust gas temperature threshold in the above can be set to 95℃.

[0103] Further, if the exhaust gas temperature is less than or equal to the exhaust gas temperature threshold, in order to accurately adjust the opening of the second throttling element and thereby distribute the proportion of refrigerant, the opening change value of the second throttling element determined according to the middle portion temperature of the coil, the outlet temperature of the coil, and the water temperature of the water tank includes:

[0104] determining an actual supercooling degree according to the middle portion temperature of the coil and the outlet temperature of the coil;

[0105] querying a target supercooling degree corresponding to the water temperature of the water tank;

[0106] determining the opening change value of the second throttling element according to the target supercooling degree and the actual supercooling degree.

[0107] It can be understood that the target supercooling degree is negatively correlated with the water temperature of the water tank, and generally the larger the water temperature of the water tank, the smaller the target supercooling degree. When querying the target supercooling degree corresponding to the water temperature of the water tank, Table 1 can be referred to.

[0108] Table 1

[0109] Water tank water temperature Tw Target supercooling degree (°C) Tw < 20 In the range [8, 16], for example 12 20 < Tw < 30 In the range [6, 12], for example 7 30 < Tw < 40 In the range [4, 10], for example 5 40 < Tw < 50 In the range [2, 8], for example 4 50 ≤ Tw In the range [0, 6], for example 4

[0110] It should be noted that the actual supercooling degree refers to the difference between the middle portion temperature of the coil and the outlet temperature of the coil, and the opening change value of the second throttling element refers to the difference between the actual supercooling degree and the target supercooling degree.

[0111] Step S302: Adjusting the opening of the second throttling element according to the opening change value.

[0112] In the present embodiment, there are different adjustment methods for adjusting the opening of the second throttling element according to the size of the opening change value, and the adjusting the opening of the second throttling element according to the opening change value includes:

[0113] when the opening change value is greater than a preset threshold, adjusting the opening of the second throttling element according to the opening change value and a preset first coefficient;

[0114] when the opening change value is less than or equal to the preset threshold, adjusting the opening of the second throttling element according to the opening change value and a preset second coefficient, the preset first coefficient being greater than the preset second coefficient.

[0115] In a specific implementation, taking 0 as the preset threshold, 3 as the preset first coefficient, and 1 as the preset second coefficient as examples, adjustment of the second throttling original opening degree is specifically as follows: when the opening degree change value > 0, the electronic expansion valve opening degree = original opening degree + opening degree change value * 3; when the opening degree change value ≤ 0, the electronic expansion valve opening degree = original opening degree + opening degree change value * 1.

[0116] Further, when adjusting the opening degree of the first throttling element corresponding to the indoor heat exchanger, there are two control modes. The step of adjusting the opening degree of the first throttling element according to the first opening degree control mode specifically includes:

[0117] Obtaining an outdoor environment temperature of a region where the air conditioner outdoor unit is located;

[0118] Determining a target opening degree corresponding to the outdoor environment temperature;

[0119] Adjusting the opening degree of the first throttling element according to the target opening degree.

[0120] It can be understood that when the target opening degree corresponding to the outdoor environment temperature is determined, Table 2 can be referred to.

[0121] Table 2

[0122] T4≥5℃ A1, in the range [20, 80], for example 54B -5℃≤T4<5℃ A2, in the range [20, 80], for example 50B -12℃≤T4<-5℃ A3, in the range [20, 80], for example 46B T4<-12℃ A4, in the range [20, 80], for example 40B

[0123] For example, if the water temperature of the heating water tank is 30℃, the opening degree of the first throttling element can be adjusted according to the first control mode. At this time, if the outdoor environment temperature of the region where the air conditioner outdoor unit is located is 5℃, the opening degree of the first throttling element is 54B.

[0124] Further, the step of adjusting the opening degree of the first throttling element according to the second opening degree control mode specifically includes:

[0125] Obtaining a middle temperature of a target indoor heat exchanger with a heating demand and a mean value of middle temperatures corresponding to each target indoor heat exchanger;

[0126] Calculating a temperature difference value between the middle temperature and the mean value of the middle temperatures;

[0127] Determining a to-be-adjusted opening degree change value corresponding to the temperature difference value;

[0128] Adjusting the opening degree of the first throttling element according to the to-be-adjusted opening degree change value.

[0129] It should be noted that if the water temperature of the heating water tank is greater than or equal to 42℃, the opening adjustment of the first throttling element can be adjusted according to the second control mode, at this time, the opening of the first throttling element is initialized to a certain set initial opening, and is maintained for a certain time, and after initialization, the correction control is performed, and the correction control logic is to calculate the temperature difference between the middle part temperature of the target indoor heat exchanger with heating demand and the average temperature of the middle part temperature of all indoor heat exchangers with heating demand, and then query the first throttling element opening change value corresponding to the temperature difference, wherein the specific process of querying the first throttling element opening change value corresponding to the temperature difference can refer to Table 3.

[0130] Table 3

[0131] Condition Opening degree change T2i-T2avg < -3°C a1, in the range [+8, +16], for example +10 -3 ≤ T2i-T2avg < -1°C a2, in the range [+4, +10], for example +6 -1 ≤ T2i-T2avg ≤ 1°C a3, in the range [-4, +4], for example 0 1 < T2i-T2avg ≤ 3°C a4, in the range [-8, 0], for example -4 T2i-T2avg > 3°C a5, in the range [-16, -4], for example -8

[0132] Wherein, T2i refers to the middle part temperature of the target indoor heat exchanger with heating demand, and T2avg refers to the average temperature of the middle part temperature of all target indoor heat exchangers with heating demand.

[0133] The embodiment adjusts the opening of the first throttling element and / or the second throttling element of the hydraulic module corresponding to the air conditioner indoor unit according to the water tank temperature to balance the heating and hot water capacity demand under different demands and improve the heating effect of the air conditioner indoor unit and the hot water effect of the hydraulic module.

[0134] Reference Figure 5 , Figure 5 The flowchart of the third embodiment of the air conditioner control method of the application is shown.

[0135] Based on the first embodiment, in the embodiment, the step S20 further comprises:

[0136] Step S310: judging whether the refrigerant circuit in the air conditioner is abnormal in pressure according to the middle part temperature of the coil and the water tank temperature.

[0137] It should be noted that whether the refrigerant circuit in the multi-split air conditioner is abnormal in pressure can be that the middle part temperature of the coil is greater than 53℃ within 1min, or when the multi-split air conditioner has both heating and hot water demand, after running for 20min, if the difference between the middle part temperature of the coil and the water tank temperature Tw is less than 1℃ for 5min.

[0138] Step S320: if yes, adjusting the opening degree of the second throttling element according to the middle portion temperature of the coil and / or the water tank temperature until the difference between the middle portion temperature of the coil and the water tank temperature is greater than a preset first temperature threshold for a duration greater than a preset first duration, or the water tank temperature is greater than the set temperature of the heating water tank.

[0139] In a specific implementation, if the multi-split air conditioner is in the pressure abnormality, it indicates that the multi-split air conditioner has poor heating effect for at least one of heating and heating water, and the adjusting the opening degree of the second throttling element according to the middle portion temperature of the coil includes:

[0140] When the middle portion temperature of the coil is greater than or equal to a preset second temperature threshold, screening the opening degree change value to obtain a target opening degree change value, the target opening degree change value is an opening degree change value greater than or equal to a preset threshold; and adjusting the opening degree of the second throttling element according to the target opening degree change value.

[0141] It can be understood that the preset second temperature threshold can be 53℃, and the process of screening the opening degree change value to obtain the target opening degree change value can be to eliminate the part of the opening degree change value less than 0, that is, the second throttling element is not allowed to be adjusted smaller.

[0142] In addition, when the multi-split air conditioner has both heating and heating water demand, after running for 20 minutes, if the difference between the middle portion temperature of the coil and the water tank temperature Tw is less than 1℃ for 5 consecutive minutes, and the corresponding point electric auxiliary heating device of the heating water tank is turned on for electric heating, the opening degree of the second throttling element can be directly adjusted to 55B.

[0143] In a specific implementation, if the multi-split air conditioner enters the pressure abnormality state and is controlled by the corresponding control strategy, and any one of the following conditions is met: the difference between the middle portion temperature of the coil and the water tank temperature Tw is greater than 4℃ for 10 consecutive seconds; when the water tank temperature Tw is greater than or equal to the set temperature Tws of the water tank, the control can be exited.

[0144] The embodiment judges whether the refrigerant in the multi-split air conditioner has a pressure abnormality, and if yes, adjusts the opening degree of the second throttling element according to the detected control strategy corresponding to the pressure abnormality, avoids affecting the effect of heating or heating water, and improves the user experience.

[0145] In addition, the embodiment of the present application also provides a storage medium, and the storage medium stores an air conditioner control program, and the air conditioner control program is executed by a processor to realize the steps of the air conditioner control method as described above.

[0148] As Figure 6 shown, the air conditioner control device provided by the embodiment includes:

[0149] The acquisition module 10 is configured to acquire the water tank temperature of the water module when the air conditioner simultaneously has a heating demand and a hot water demand.

[0150] It should be noted that the air conditioner in the embodiment refers to a multi-split air conditioner, and the multi-split air conditioner is an air conditioner that connects one outdoor unit to multiple indoor units and can adjust the air temperature, humidity, cleanliness, and air flow rate of multiple rooms simultaneously, including but not limited to cooling, heating, and fresh air circulation modes. Figure 3 It should be noted that the multi-split air conditioner in the embodiment includes an air conditioner outdoor unit, an air conditioner indoor unit, and a water module, the outdoor unit is connected to each air conditioner indoor unit and the water module, the air conditioner outdoor unit includes a compressor, an outdoor heat exchanger, and at least two reversing devices, the air conditioner indoor unit includes at least one indoor heat exchanger, and the water module is provided with a hot water tank at the end, wherein each reversing device is connected to the compressor and is mainly used to control the flow direction of the refrigerant in the multi-split air conditioner, and the reversing device can be a four-way valve or a three-way valve, which is not limited in the embodiment.

[0151] In addition, the air conditioner outdoor unit is provided with a throttling element between each air conditioner indoor unit and the water module, and the throttling element in the embodiment includes a first throttling element corresponding to the indoor heat exchanger and a second throttling element corresponding to the hot water tank, wherein the throttling element includes an electronic expansion valve and a capillary tube, and in the embodiment, the electronic expansion valve is mainly taken as an example for description, wherein the throttling element between the air conditioner outdoor unit and each air conditioner indoor unit and the water module can include a main road electronic expansion valve and a corresponding branch electronic expansion valve of each air conditioner indoor unit or the water module, which is not limited in the embodiment.

[0152]

[0153] ​It can be understood that when the air conditioner indoor unit of the multi-split air conditioner is in heating operation, the refrigerant is compressed by the compressor to obtain high-temperature and high-pressure refrigerant, the high-temperature and high-pressure refrigerant is delivered to the indoor heat exchanger through the four-way valve for condensation heat dissipation, after heat exchange with the indoor environment through the indoor heat exchanger, medium-temperature and high-pressure refrigerant is obtained, and then the medium-temperature and high-pressure refrigerant passes through the electronic expansion valve and the main path capillary and other throttling elements in the foregoing to obtain low-pressure and medium-temperature refrigerant, which is delivered to the outdoor heat exchanger for evaporation to obtain low-temperature and low-pressure refrigerant, and finally the low-temperature and low-pressure refrigerant is returned to the compressor through the four-way valve to complete a single heating process.

[0154] When the multi-split air conditioner has a heating water demand, the refrigerant is compressed by the compressor to obtain high-temperature and high-pressure refrigerant, the high-temperature and high-pressure refrigerant is delivered to the heating water tank through the four-way valve, the heating water tank acts as a condenser, and after heat exchange with the water path in the heating water tank, the outlet water temperature is higher than the inlet water temperature to realize heating, the refrigerant flows through the water path of the heating water tank to obtain medium-temperature and high-pressure refrigerant, and then the medium-temperature and high-pressure refrigerant passes through the electronic expansion valve and the main path capillary and other throttling elements in the foregoing to obtain low-pressure and medium-temperature refrigerant, which is delivered to the outdoor heat exchanger for evaporation to obtain low-temperature and low-pressure refrigerant, and finally the low-temperature and low-pressure refrigerant is returned to the compressor through the four-way valve to complete a single heating process.

[0155] It should be understood that the water tank temperature includes but is not limited to the middle temperature of the coil, the outlet temperature of the coil, and the water temperature in the water tank, wherein the water tank temperature can be the average value between the water temperature at the upper part of the water tank and the water temperature at the lower part of the water tank, the middle temperature of the water tank coil refers to the refrigerant saturation temperature corresponding to the compressor discharge pressure, in the embodiment, the refrigerant saturation temperature is related to the refrigerant category, the refrigerant pressure and other factors, and its main functions are temperature control, heat exchange and improvement of energy efficiency, considering that there is pressure loss when the refrigerant passes through various heat exchanger devices, and there is basically no pressure loss when the refrigerant is transmitted in the pipeline, in the embodiment, the middle temperature of the coil of the heating water tank directly connected with the compressor refrigerant output end is taken as the refrigerant saturation temperature corresponding to the compressor discharge pressure.

[0156] The determining module 20 is configured to determine the air conditioner control mode corresponding to the water tank temperature.

[0157] In the embodiment, different control modes of different throttling elements have different control logics, for example: for the control mode of the first throttling element corresponding to the indoor heat exchanger, there are two control modes, one is to adjust the opening degree of the first throttling element according to the opening degree corresponding to the outdoor environment temperature, and the other is to determine the temperature difference value according to the middle temperature of the indoor heat exchanger with heating demand and the average value of the middle temperatures of the indoor heat exchangers with capacity demand, and adjust the opening degree of the first throttling element according to the opening degree corresponding to the temperature difference value.

[0158] As for the control mode of the second throttling element corresponding to the heating water tank, the control mode of the second throttling element is determined to be automatic control or abnormal control according to the middle portion temperature of the heating water tank coil, the water tank water temperature and the coil outlet temperature, and the embodiment does not make specific limitation.

[0159] Further, the determining the air conditioner control mode corresponding to the water tank temperature comprises:

[0160] When the water tank temperature is in the first temperature interval, a first opening degree control mode is run to adjust the opening degree of the first throttling element;

[0161] When the water tank temperature is in the second temperature interval, the last run opening degree control mode is run, and the minimum value of the second temperature interval is greater than the maximum value of the first temperature interval;

[0162] When the water tank temperature is in the third temperature interval, a second opening degree control mode is run to adjust the opening degree of the first throttling element, and the minimum value of the third temperature interval is greater than the maximum value of the second temperature interval.

[0163] In a specific implementation, the water tank temperature mentioned above mainly refers to the water tank water temperature, that is, the water tank water temperature Tw < TW1 °C is controlled in a first control mode, the water tank water temperature Tw > TW2 °C (42 °C) is controlled in a second control mode, and the water tank water temperature 39 °C ≤ Tw ≤ 42 °C maintains the last control mode. When the multi-split air conditioner is powered on for the first time, the control mode 2 is executed, wherein the first control mode refers to a control mode in which heating water is given priority and a heating indoor unit is in a standby state; and the second control mode refers to a control mode in which the heating indoor unit and the heating water run simultaneously.

[0164] TW1 °C can be 39 °C, and TW2 °C can be 42 °C, and the embodiment does not make specific limitation.
