In specific implementation, when the indoor air conditioner of the multi-split air conditioner is used for heating operation, a refrigerant is compressed by a compressor to obtain a high-temperature and high-pressure refrigerant, the high-temperature and high-pressure refrigerant is conveyed to an indoor heat exchanger through a four-way valve to be condensed and radiated, after heat exchange between the indoor heat exchanger and an indoor environment, the medium-temperature and high-pressure refrigerant is obtained, the medium-temperature and low-pressure refrigerant is obtained through throttling elements such as the electronic expansion valve and a main capillary tube, the medium-temperature and low-pressure refrigerant is conveyed to an outdoor heat exchanger to be evaporated, the low-temperature and low-pressure refrigerant is obtained, and finally the low-temperature and low-pressure refrigerant flows back to the compressor through the four-way valve to complete a single heating process.

It can be understood that the heating simultaneous-on mode refers to a mode that the hydraulic module and the air conditioner indoor unit are in an operation state at the same time, in the mode, because the hydraulic module and the air conditioner indoor unit are different in use field Jing Gongkuang, the pressure deviation between the hydraulic module and the air conditioner indoor unit is larger, and when the hydraulic module operates in a low water temperature interval, because the pressure of the hydraulic module is lower, the refrigerant flows to the hydraulic module with low pressure, so that the air conditioner indoor unit has no heating capacity, and blows cold air; when the hydraulic module is in a high water temperature interval, because the pressure of the air conditioner indoor unit is low, the refrigerant flows to the air conditioner side with low pressure, so that the hydraulic module cannot establish high pressure, the heating water cannot be heated, and the heating water cannot reach the required water temperature by using the heat pump unit.
It should be understood that the outlet water temperature of the hydraulic module refers to the water temperature after being heated by the water side heat exchanger or the electric auxiliary heating device; the outdoor environment temperature of the area where the external machine is located can be the temperature collected through a temperature sensor or a temperature sensing bulb arranged on a shell of the external machine, or can be the temperature collected by the temperature sensing bulb at the position of the external heat exchanger in the external machine, wherein if a plurality of external heat exchangers exist in the external machine, the average value of the temperatures collected by the temperature sensing bulbs at the positions of the external heat exchangers can be taken as the outdoor environment temperature, so that the influence of the outdoor environment temperature on the control scheme in the embodiment is reduced; the device temperature specifically includes the exhaust temperature at the outlet of the compressor in the external machine and the coil temperature or the middle temperature of the indoor heat exchanger, and meanwhile, if there are multiple connected internal machines or multiple indoor heat exchangers in a single internal machine, the coil temperature average value of each indoor heat exchanger can be taken as the coil temperature of the indoor heat exchanger, which is not specifically limited in this embodiment.

It is understood that the water temperature adjustment interval includes: a low water temperature adjusting section, a normal water temperature adjusting section and a high water temperature adjusting section, wherein the low water temperature adjusting section represents that more refrigerant possibly exists in the hydraulic module and the heat capacity of a mechanism in the air conditioner is affected; the normal water temperature adjustment interval shows that the refrigerant flow direction between the air conditioner indoor unit and the hydraulic module is not greatly different, and the heating capacity is not greatly improved; the high water temperature adjustment interval indicates that more refrigerant possibly exists in the air conditioner, so that the heating capacity of the hydraulic module is affected.

Step S30: and determining the opening change value of each throttling element according to the equipment temperature and the water temperature adjustment interval.
It should be noted that, different water temperature adjustment intervals indicate that the heating requirements of the air conditioner indoor unit and the hydraulic module are different, so that the refrigerant distribution ratio is also different.
Step S40: and adjusting the opening of each throttling element according to the opening variation value.
It should be understood that, in the low water temperature adjustment interval, since the heating requirement of the hydraulic module is larger, the refrigerant flows through the hydraulic module in a large amount, the opening of the second throttling element between the hydraulic module and the external machine can be reduced, or the opening of the first throttling element between the internal machine and the external machine of the air conditioner and the second throttling element between the hydraulic module and the external machine of the air conditioner are reduced, but the opening of the second throttling element is adjusted more, and the opening of the first throttling element can be increased, or the opening of the first throttling element is increased more than the opening of the second throttling element, so as to reduce the amount of the refrigerant flowing into the hydraulic module, avoid the influence of the heat capability of the mechanism in the air conditioner, and blow out the cold air.
Similarly, in the high water temperature adjusting section, because the refrigerant flows through the air conditioner inner unit in a large quantity, the opening degree of the second throttling element between the hydraulic module and the outer unit can be increased, or the opening degree of the first throttling element between the air conditioner inner unit and the outer unit and the second throttling element between the hydraulic module and the outer unit can be increased, but the opening degree of the second throttling element is adjusted more, the opening degree of the first throttling element can be reduced, or the opening degree of the first throttling element is reduced by a larger amplitude than the opening degree of the second throttling element, so that the quantity of the refrigerant flowing into the hydraulic module is reduced, and the influence on the mechanism heat capability in the air conditioner is avoided.
According to the embodiment, when the air conditioner is operated in the heating and simultaneous-on mode, the water temperature adjustment interval where the air conditioner is currently located is comprehensively judged through the water outlet temperature and the outdoor environment temperature of the water power module of the air conditioner, so that the follow-up targeted selection is facilitated, the opening degree variation value of each throttling element is calculated through the equipment temperature of the air conditioner, the pipeline pressure difference between the heating capacity of the air conditioner inner unit or the water power module and the outer unit is accurately regulated, the technical problem that the heating capacity of the water power module and the heating capacity of the air conditioner inner unit are easily influenced when the water power module and the air conditioner inner unit are operated simultaneously in the prior art is avoided, the use experience of a user in heating water or heating is improved, and the comfort of the user in use is improved.
Referring to fig. 4, fig. 4 is a flowchart illustrating a control method of an air conditioner according to a second embodiment of the present invention.
Based on the first embodiment, in this embodiment, the step S30 includes:
step S301: and obtaining the target exhaust temperature of the compressor, the coil temperature average value of the indoor heat exchangers of the air conditioner indoor units in the starting state and the target coil temperature.
It should be noted that the target discharge temperature of the compressor refers to a theoretical discharge temperature at a current outdoor environment temperature and a current compressor operating frequency, and then, since a part of air conditioner indoor units exist in the multi-split air conditioner, the air conditioner indoor units are in a non-standby or shutdown state.
The target coil temperature is a coil temperature theoretically corresponding to the indoor heat exchanger after the user sets a desired temperature, and in this embodiment, the target coil temperature is 35345 ℃.
Step S302: and calculating a first temperature difference value between the exhaust temperature and the target exhaust temperature, and determining a first temperature difference interval where the first temperature difference value is located.
It can be appreciated that the first temperature difference interval may be set with reference to table 2, and a mapping relationship exists between a temperature difference between the exhaust temperature and the target exhaust temperature and an opening variation value of the throttling element, where the mapping relationship may be defined by a user, and may be obtained by performing experiments in advance, for example: the temperature rise values of the air conditioner internal unit and the hydraulic module are limited, the air conditioner internal unit or the hydraulic module is independently operated, the exhaust temperature and the target exhaust temperature are obtained, the opening degree of the throttling element is determined when the temperature difference is the same, and then the mapping relation between the exhaust temperature and the target exhaust temperature and the opening degree change value of the throttling element is obtained.

Where TP refers to the discharge temperature of the compressor, and tp_tar refers to the target discharge temperature.
Step S303: and calculating a second temperature difference value between the coil temperature average value and the target coil temperature, and determining a second temperature difference interval where the second temperature difference value is located.
It can be understood that the second temperature difference interval can be set with reference to table 3, and a mapping relationship exists between a temperature difference value between a coil temperature average value and a target coil temperature and an opening change value of the throttling element, where the mapping relationship can be defined by a user, and can be obtained by performing a test in advance, and the embodiment is not limited specifically.

| -1＜T2_Aver-T2_Tar≤1 | 0 |
| 1＜T2_Aver-T2_Tar≤3 | +4 |
| T2_Aver-T2_Tar＞3 | +10 |
Wherein T2_Aver refers to the coil temperature average value of the indoor heat exchangers of the air conditioner indoor units in the starting state, and T2_Tar refers to the target coil temperature.
Step S304: and when the water temperature adjusting interval is a low water temperature adjusting interval, determining the opening change value of the first throttling element according to the first temperature difference interval and the second temperature difference interval.
It should be noted that, when the air conditioner is in the low water temperature adjustment interval, according to the first temperature difference between the exhaust temperature and the target exhaust temperature and the second temperature difference between the coil temperature average value and the target coil temperature, the opening change value of the first throttling element is obtained, so as to adjust the opening of the first throttling element between the air conditioner inner unit and the air conditioner outer unit, for example: the first temperature difference is-4 degrees celsius, the second temperature difference is 2 degrees celsius, and then according to table 2 and table 3, it can be comprehensively determined that the opening change value of the first throttling element is about-10 steps, in this embodiment, the opening adjustment corresponding to the positive and negative steps is opposite, for example: the positive step number indicates an increase in the opening degree, and the negative step number indicates a decrease in the opening degree, or vice versa, which is not particularly limited in this embodiment.
Step S305: and determining the opening change value of the second throttling element according to the second temperature difference interval.
In a specific implementation, if the air conditioner is in the low water temperature adjustment interval, the opening of the second throttling element between the hydraulic module and the external machine is determined by the difference between the coil temperature average value and the target coil temperature, for example: and if the second temperature difference between the coil temperature average value and the target coil temperature is 0 ℃, the opening degree change value of the second throttling element is 0, and no adjustment is performed.
Further, after determining the opening degree variation value of the second throttling element according to the second temperature difference interval, the method further includes:
acquiring a temperature rise difference value of the water outlet temperature of the hydraulic module at intervals of preset time length;
and when the temperature rise difference is smaller than the first temperature, starting the electric auxiliary heating device to heat the hydraulic module.
It can be understood that after the air conditioner enters the low water temperature adjustment interval, the outlet water temperature of the hydraulic module can be detected at intervals of a certain period of time, so as to determine whether the heating capacity of the hydraulic module can meet the requirement of a user after the throttling element is adjusted, and the preset period of time can be set to 10 minutes, which is not particularly limited in this embodiment.
In a specific implementation, the first temperature may be set to 2 ℃, that is, the air conditioner enters a low water temperature adjustment interval, the compressor operates for 10min, if the temperature rise difference of the outlet water temperature of the hydraulic module is less than 2 ℃, the heating capacity of the hydraulic module is insufficient to meet the user demand, and an additional heating device is needed to heat, and in the embodiment, the electric auxiliary heating device arranged in the hydraulic module is used for heating the outlet water channel of the water side heat exchanger so as to achieve the purpose of improving the outlet water temperature; if the temperature rise difference of the water outlet temperature of the hydraulic module is not less than 2 ℃, the heating capacity of the hydraulic module is enough, the current running state is maintained, and the electric auxiliary heating device is not required to be started.
In addition, after the air conditioner is in the low water temperature adjusting section and the opening degree of each throttling element is adjusted, the heating capacity of the hydraulic module can be displayed to be improved, and in order to improve the use experience of a user, the water outlet temperature of the hydraulic module and the minimum value of the water outlet temperature of the set low water temperature section can be detected and judged. When the outlet water temperature is smaller than the minimum value, maintaining the control of a low water temperature adjusting interval; when the temperature of the discharged water is greater than or equal to the minimum value, the control of the low water temperature adjusting interval is exited, the electric heating of the hydraulic module is closed, and the normal adjusting interval is entered.
In addition, in order to avoid cold air blowing of the air conditioner indoor unit, the rotating speed of the fan of the air conditioner indoor unit can be controlled.
Further, after calculating a second temperature difference between the coil temperature average value and the target coil temperature and determining a second temperature difference interval in which the second temperature difference is located, the method further includes:
when the water temperature adjusting interval is a normal water temperature adjusting interval, determining an opening change value of a first throttling element according to the first temperature difference interval and the second temperature difference interval;
and determining the opening change value of the second throttling element according to the first temperature difference interval.
When the air conditioner is in a normal water temperature adjusting interval, the opening change value of the first throttling element is comprehensively calculated according to a first temperature difference value between the exhaust temperature and the target exhaust temperature and a second temperature difference value between a coil temperature average value and the target coil temperature; the opening degree variation value of the second throttle element is determined by a first temperature difference between the exhaust gas temperature and the target exhaust gas temperature.
Meanwhile, after the air conditioner is positioned in a normal water temperature adjusting section and the opening degree of each throttling element is adjusted, in order to avoid overflow of heating capacity of the hydraulic module or the air conditioner internal unit, electric power resources are saved, the use experience of a user is improved, the water outlet temperature of the hydraulic module and the maximum value of the water outlet temperature of a set high water temperature section can be detected and judged, and when the water outlet temperature is smaller than the maximum value, the control of the low water temperature adjusting section is maintained; when the temperature of the water outlet is greater than or equal to the minimum value, the control of the normal regulation interval is exited, and the high water temperature regulation interval is entered.
Further, after calculating a second temperature difference between the coil temperature average value and the target coil temperature and determining a second temperature difference interval in which the second temperature difference is located, the method further includes:
when the water temperature adjusting interval is a high water temperature adjusting interval, determining an opening change value of the second throttling element according to the second temperature difference interval;
and determining the opening variation value of the first throttling element according to a preset opening extremum.
In a specific implementation, when the air conditioner is in a high water temperature regulation interval, the opening change value of the first throttling element is determined by a preset opening extremum, wherein the preset opening mechanism refers to a fixed minimum opening of the first throttling element, and the opening change value of the second throttling element is determined by a first temperature difference value between the exhaust temperature and the target exhaust temperature.
It is worth to say that, in the high water temperature adjustment interval, because the heating demand of the air conditioner internal unit is higher, the air conditioner can distribute refrigerant to the air conditioner internal unit in a large number, therefore when the hydraulic module needs to heat, the situation that heating is insufficient probably occurs, and the water channel in the hydraulic module can be heated through the electric auxiliary heating device, so that the heating capacity of the hydraulic module is improved.
Further, the air conditioner control method further includes:
when the water temperature adjusting interval is a high water temperature adjusting interval, the rotating speed of the fan is adjusted according to a second temperature difference interval;
acquiring a temperature rise difference value of the water outlet temperature of the hydraulic module at intervals of preset time length;
and when the temperature rise difference is smaller than the first temperature, starting the electric auxiliary heating device to heat the hydraulic module.
It can be understood that after the air conditioner enters the high water temperature adjustment interval, the outlet water temperature of the hydraulic module can be detected at intervals of a certain period of time, so that after the throttle element is adjusted, the heating capacity of the hydraulic module is too low, the preset period of time can be set to be 10min, and the embodiment is not particularly limited.
If the air conditioner enters a high water temperature adjusting interval and the temperature rise difference of the water outlet temperature of the hydraulic module is smaller than 2 ℃ after the compressor runs for 10min, the heating capacity of the hydraulic module is too low, an additional heating device is needed for heating, and at the moment, the electric auxiliary heating device is started for heating the waterway; if the temperature rise difference of the water outlet temperature of the hydraulic module is not less than 2 ℃, the heating capacity of the hydraulic module is enough, the current running state is maintained, and the electric auxiliary heating device is not required to be started.
In a specific implementation, the adjustment of the fan gear or the fan rotation speed may refer to table 4, and a mapping relationship exists between the second temperature difference between the coil temperature average value and the target coil temperature and the fan rotation speed or the fan gear, where the mapping relationship may be defined by a user, and may be obtained by performing a test in advance, and this embodiment is not limited specifically.

| T2_Aver-T2_Tar≤-3 | -20％ |

| -1＜T2_Aver-T2_Tar≤1 | 0％ |
| 1＜T2_Aver-T2_Tar≤3 | +8％ |
| T2_Aver-T2_Tar＞3 | +16％ |
Wherein T2_Aver refers to the coil temperature average value of the indoor heat exchangers of the air conditioner indoor units in the starting state, and T2_Tar refers to the target coil temperature.
Further, after the electric auxiliary heating device is started, the method further comprises:
acquiring a temperature rise difference value of the water outlet temperature of the hydraulic module at intervals of preset time length;
when the temperature rise difference value is smaller than the first temperature, controlling the fan to stop running;
and controlling the air conditioner indoor unit to enter a standby state until the hydraulic module reaches Wen Tingji.
In a specific implementation, after the electric auxiliary heating device of the hydraulic module is started, if the difference of the temperature rise of the water outlet temperature of the hydraulic module is not less than 2 ℃, the heating capacity of the hydraulic module is enough at the moment, but if the electric auxiliary heating device of the hydraulic module is started, the difference of the temperature rise of the water outlet temperature of the hydraulic module is still less than 2 ℃, at the moment, the air conditioner indoor unit needs to be treated, the heating capacity of the hydraulic module is preferentially improved, namely, the air conditioner indoor unit fan is turned off, and the air conditioner indoor unit is turned into a standby state until the hydraulic module reaches the temperature and is switched to an air conditioner indoor unit mode.
According to the embodiment, the opening degree of the throttling element of the air conditioner in the low water temperature adjusting section, the normal water temperature adjusting section and the high water temperature adjusting section is adjusted, so that heating requirements when the hydraulic module and the air conditioner indoor unit are simultaneously started by the air conditioner are met to the maximum extent, and comfort when a user uses a heating same-opening mode is improved.
