Of course, other devices with similar functions may be used, and the implementation conditions are not limited thereto. For convenience of explanation, the present embodiment will be described with reference to a controller of a multi-split air conditioner.
It should be noted that, the air conditioner in this embodiment refers to a multi-split air conditioner, where one external machine is connected to multiple internal machines, and the multi-split air conditioner can implement the functions of adjusting parameters such as air temperature, humidity, cleanliness, air flow rate and the like of multiple rooms at the same time, including but not limited to modes such as refrigeration, heating, fresh air circulation and the like.

It can be understood that, in the multi-split air conditioner of this embodiment, the output end of the compressor 11 is connected to the first communication port of the four-way valve 13, and is connected to the pressure valve 16 (low-pressure valve) through the second communication port of the four-way valve 13, so as to be convenient for conveying to the air conditioner indoor unit 2 or the hydraulic module 3 for heat exchange, after the heat exchange is completed, the air flows back to the electronic expansion valve through the pressure valve 16 (high-pressure valve), and then is conveyed to the outdoor heat exchanger 14 through the main capillary tube for evaporation and heat absorption, at this time, the outdoor heat exchanger 14 is used as an evaporator, and finally flows through the vapor-liquid separator 12 through the third communication port and the fourth communication port of the four-way valve 13, and returns to the compressor 11, so that the next heating is facilitated, wherein the number of the high-pressure valves is twice that of the electronic expansion valves.
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.
Meanwhile, when the heating water of the multi-split air conditioner runs, the refrigerant is compressed by the compressor to obtain a high-temperature and high-pressure refrigerant, the high-temperature and high-pressure refrigerant is conveyed to the water side heat exchanger in the heat exchange module through the four-way valve to be condensed and radiated, the water side heat exchanger is used as the condenser, the water temperature is higher than the water inlet temperature after heat exchange with the water channel in the water side heat exchanger, the water channel flowing through the water side heat exchanger is heated, the medium-temperature and high-pressure refrigerant is obtained, the medium-temperature and low-temperature refrigerant is obtained through the throttling element such as the electronic expansion valve and the main capillary tube, the low-temperature and medium-temperature refrigerant is conveyed to the outdoor heat exchanger to be evaporated, the low-temperature and low-pressure refrigerant is finally returned to the compressor through the four-way valve, the single heating process is completed, meanwhile, the heated water channel flows back to the water tank through the electric auxiliary heat device and the three-way valve to realize the heating of the water, and the water tank is stored if the redundant hot water exists, and the water can be used next time.
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, in the conventional technology, when the multi-split air conditioner is controlled to operate, peak shifting operation of the air conditioner internal unit and the hydraulic module is generally limited, and the control scheme cannot meet the use requirement of a user and cannot maximally exert the external mechanism heat energy capacity of the multi-split air conditioner.
In this embodiment, the water inlet temperature of the hydraulic module refers to the water temperature of the water inlet pipeline as shown in fig. 3, and may also be the water temperature of the water body without heat exchange of the water side heat exchanger; 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 indoor environment temperature of the area where the air conditioner indoor unit is in the starting state refers to the environment temperature of the room where the air conditioner indoor unit with the internal requirement exists, and can be the temperature acquired by a temperature sensor or a temperature sensing bag installed on the indoor heat exchanger, and the indoor environment temperatures corresponding to the air conditioner indoor units can possibly be different, so that the embodiment can correspondingly adjust the refrigerant input of the air conditioner indoor units through the indoor environment temperatures of the air conditioner indoor units with the internal requirement.
Step S20: and determining the critical temperature of each air conditioner indoor unit according to the indoor environment temperature and the outdoor environment temperature.
It should be noted that, the critical temperature is used for dividing the adjustment interval of the refrigerant input of the air conditioner indoor unit, and represents the heating requirement of the air conditioner indoor unit to a certain extent, in this embodiment, the higher the indoor environment temperature is, the higher the critical temperature is; the higher the outdoor environment temperature, the higher the critical temperature, and the critical temperature will not affect each other, and the critical temperature is also related to the type of the multi-split air conditioner, so that the influence of the indoor environment temperature and the outdoor environment temperature on the critical temperature of the air conditioner is more conveniently described, referring to table 1, the indoor environment temperature, the outdoor environment temperature and the critical temperature in table 1 are all illustrated, and do not represent the defined final values.
TABLE 1
Wherein, the T is the outdoor environment temperature, the T is the indoor environment temperature, the TW-critical is the different indoor environment temperature or the corresponding critical temperature under the outdoor environment temperature, wherein TW-critical 1 < TW-critical 2 < TW-critical 3 < TW-critical 4 < TW-critical 5, TW-critical 5 < TW-critical 5' and the value range of TW-critical is 5-50 ℃, for example: TW-Critical 1 may take 25 ℃, TW-Critical 2 may take 27 ℃, TW-Critical 3 may take 29 ℃, TW-Critical 4 may take 31 ℃, TW-Critical 5 may take 33 ℃, which is not particularly limited in this embodiment.
Step S30: and determining a target water temperature adjusting interval where each air conditioner indoor unit is positioned according to the water inlet temperature and each critical temperature.
In this embodiment, because the multi-split air conditioner operates the air conditioner to heat and heat water at the same time, in order to achieve better refrigerant distribution and improve the heating capacity utilization rate of the external machine, the water temperature adjustment interval is determined by the cooperation of the water inlet temperature and the critical temperature.
Further, the determining the target water temperature adjustment interval where each air conditioner is located according to the water inlet temperature and each critical temperature includes:
determining a target critical temperature corresponding to the target air conditioner indoor unit;
dividing a plurality of water temperature adjustment intervals according to the target critical temperature and a preset temperature correction value;
and matching the water inlet temperature with each water temperature adjusting interval to determine a target water temperature adjusting interval where each air conditioner indoor unit is located.
It should be noted that, the target air conditioner indoor unit refers to any air conditioner indoor unit requiring heating energy, and since the critical temperature of each air conditioner indoor unit is positively correlated with the indoor environment temperature and the outdoor environment temperature of the air conditioner indoor unit, the target critical temperature corresponding to the target air conditioner indoor unit is obtained through the table 1 described above in this embodiment.
It will be appreciated that, since the difference between the indoor environment temperature and the outdoor environment is not very large, and the inlet water temperature may take a larger value, there is a larger error in matching the inlet water temperature and the water temperature adjustment interval subsequently, this error may be reduced by setting a preset temperature correction value, the value range of the preset temperature correction value is (0, 20 ℃), and in this embodiment, the preset temperature correction value includes: a first temperature correction value, a second temperature correction value and a third temperature correction value, wherein the first temperature correction value is larger than the second temperature correction value, and the second temperature correction value is larger than the third temperature correction value.
In addition, when determining the target water temperature adjustment interval where each air conditioner indoor unit is located in another manner, after determining the target critical temperature corresponding to the target air conditioner indoor unit, the method further includes:
calculating a temperature difference between the inlet water temperature and the target critical temperature;
comparing the temperature difference value with a preset temperature correction value;
and determining a target water temperature adjusting interval where each air conditioner indoor unit is located according to the comparison result.
It can be understood that the temperature difference between the inlet water temperature and the target critical temperature is calculated first, and the temperature difference is compared with the first temperature correction value, the second temperature correction value and the third temperature correction value respectively, and the target water temperature adjustment interval of each air conditioner is divided according to the comparison result.
Step S40: and adjusting the running state of each air conditioner indoor unit according to the target water temperature adjusting interval.
It should be noted that, adjusting the operation state of the air conditioner indoor unit includes, but is not limited to, adjusting the opening of a first throttling element in the air conditioner indoor unit or adjusting the rotation speed of an air supply fan, where the air supply fan is used to control the air supply amount of the air conditioner indoor unit, and the first throttling element is used to control the flow rate or the flow velocity of the refrigerant.
According to the embodiment, when the air conditioner is operated to heat the same-time opening mode, the critical temperature of each air conditioner inner unit is judged according to the indoor environment temperature and the outdoor environment temperature of each air conditioner inner unit, the current heating requirement of the air conditioner is quantified, the water inlet temperature of the hydraulic module is acquired again to judge the heating requirement of the hydraulic module, the heating requirement of each air conditioner inner unit is combined to regulate the operation state of the air conditioner, the heating requirement of the hydraulic module is preferentially met, the heating requirement of the air conditioner inner unit is weakened, the problem that the outer units cannot be operated simultaneously when the air conditioner inner unit and the hydraulic module are operated simultaneously in the prior art is solved, and the use experience of a user 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 application.
Based on the first embodiment, in this embodiment, the step S40 includes:
step S401: and reducing the opening degree of the first throttling element, reducing the rotating speed of the fan and/or shutting down the air conditioner internal unit according to the target water temperature adjusting interval.
It should be noted that, the first throttling element refers to a device for controlling the flow of the refrigerant between the air conditioner indoor unit and the air conditioner outdoor unit, including but not limited to: the opening degree of the first throttling element can be reduced, so that the flow of the refrigerant flowing into the air conditioner indoor unit can be reduced, and the heating effect of the air conditioner indoor unit is reduced.
In the concrete realization, if the heating capacity of the air conditioner indoor unit is insufficient, cold air is sent by the air conditioner, the indoor temperature is reduced, and the heating experience of a user is affected, so that the air sending quantity can be reduced by reducing the rotating speed of a fan, and the rapid drop of the indoor temperature is avoided.
Further, the reducing the opening of the first throttling element, reducing the rotation speed of the fan and/or shutting down the air conditioner indoor unit according to the target water temperature adjustment interval includes:
when the target water temperature adjustment interval is a first water temperature adjustment interval, shutting down the air conditioner indoor unit;
when the target water temperature adjustment interval is a second water temperature adjustment interval, the rotating speed of the fan is reduced according to the water inlet temperature, and the minimum value of the second water temperature adjustment interval is larger than the maximum value of the first water temperature adjustment interval;
when the target water temperature adjustment interval is a third water temperature adjustment interval, maintaining the current running state of the air conditioner indoor unit, wherein the minimum value of the third water temperature adjustment interval is larger than the maximum value of the second water temperature adjustment interval;
when the target water temperature adjustment interval is a fourth water temperature adjustment interval, reducing the opening of the first throttling element and/or reducing the rotating speed of the fan according to the inlet water temperature, wherein the minimum value of the fourth water temperature adjustment interval is larger than the maximum value of the third water temperature adjustment interval;
and when the target water temperature adjustment interval is a fifth water temperature adjustment interval, the air conditioner indoor unit is shut down, and the minimum value of the fifth water temperature adjustment interval is larger than the maximum value of the fourth water temperature adjustment interval.
It should be noted that, from the above description, the first water temperature adjustment interval, the second water temperature adjustment interval, the third water temperature adjustment interval, the fourth water temperature adjustment interval, and the fifth water temperature adjustment interval gradually increase, that is, if the target water temperature adjustment interval where the water inlet temperature of the hydraulic module in the air conditioner is located is the first water temperature adjustment interval, the water inlet temperature is lower, the heating requirement of the hydraulic module is higher, more refrigerant is distributed to the hydraulic module, and if the heating and the heating are performed simultaneously, the air conditioner can control the air conditioner to forcibly wait because the refrigerant is less to blow cold air in the room.
If the target water temperature adjustment interval where the water inlet temperature of the hydraulic module in the air conditioner inner unit is located is the second water temperature adjustment interval, the third water temperature adjustment interval or the fourth water temperature adjustment interval, the water inlet temperature is not too low, the outer unit can simultaneously support the heating requirement of the air conditioner inner unit and the heating requirement of the hydraulic module, and can simultaneously operate heating and heating water, but in order to improve the utilization rate of the heat energy of the outer unit, the air conditioner inner unit can be properly controlled, and the fan rotating speed is reduced according to the water inlet temperature in the second water temperature adjustment interval; and in a third water temperature adjustment interval, maintaining the current running state of the air conditioner indoor unit, and in a fourth water temperature adjustment interval, reducing the opening of the first throttling element and/or reducing the rotating speed of the fan according to the water inlet temperature.
If the target water temperature adjustment interval where the water inlet temperature of the hydraulic module in the air conditioner indoor unit is located is the fifth water temperature adjustment interval, the water temperature of the hydraulic module is higher, and when the water temperature is higher, the heat required for maintaining the water temperature is also higher, so as to avoid the water path water temperature in the hydraulic module from escaping too quickly to influence the user experience, the standby operation of the air conditioner indoor unit can be controlled.
According to the embodiment, different control schemes are selected through the target water temperature adjustment interval where the water inlet temperature of the water power module in the air conditioner inner unit is located, so that the opening degree of the throttling element in the air conditioner inner unit and the rotating speed of the fan are controlled, the heating requirement of the air conditioner is met, and the use experience of a user is met.

Step S203: and correcting the initial critical temperature to obtain the critical temperature of the target air conditioner indoor unit.
It is worth to say that, the initial critical temperature is corrected by the comparison between the energy requirement of the air conditioner internal unit and the energy requirement of the hydraulic module, and the method is specifically characterized in that the sum of the first energy requirement of the air conditioner internal unit in a starting state and the second energy requirement of the hydraulic module are obtained; calculating a target energy demand ratio of the air conditioner according to the first energy demand sum and the second energy demand; and correcting the initial water temperature at the street according to the target energy demand ratio.
According to the embodiment, the initial critical temperature is obtained through table lookup of the indoor environment temperature and the outdoor environment temperature, the initial critical temperature is corrected through the comparison between the energy requirement of the air conditioner internal unit and the energy requirement of the hydraulic module, the more accurate critical temperature is obtained, and the adjustment precision of the running state of the air conditioner internal unit is improved.
