Referring to fig. 1, an embodiment of the invention provides an air conditioner control method. The air conditioner control method can be applied to an air conditioner system. The air conditioning system comprises an outdoor unit and at least two indoor units.
Referring to fig. 2, the air conditioning system 100 includes an outdoor unit 10, a first indoor unit 20, and a second indoor unit 30. The outdoor unit 10 is connected to the first indoor unit 20 and the second indoor unit 30, and is respectively matched with the first indoor unit 20 and the second indoor unit 30 to achieve functions of cooling, heating, dehumidifying, air supplying, and the like, so as to meet various requirements of users. The number of the first indoor units 20 may be one or more, and the number of the second indoor units 30 may be one or more. In this embodiment, the plurality of outdoor units 10 is two or more, and the outdoor unit 10 may be a two-by-two outdoor unit (one outdoor unit and two indoor units), such as a two-by-two radiation outdoor unit variable frequency outdoor unit, a three-by-three outdoor unit (one outdoor unit and three indoor units), a four-by-four outdoor unit (one outdoor unit and four indoor units), and the like.
Referring to fig. 1, the method includes the following steps:
s10, when the setting mode of the first indoor unit 20 and the operation mode of the outdoor unit 10 are detected to conflict with each other, the first indoor unit 20 is controlled to be turned off.
The setting mode of the first indoor unit 20 includes a cooling mode, a heating mode, a dehumidifying mode, and an air supply mode, and the operation mode of the outdoor unit 10 includes a cooling mode and a heating mode.
S11, when it is detected that the setting mode of the first indoor unit 20 does not conflict with the operation mode of the outdoor unit 10, the first indoor unit 20 is controlled to operate in the setting mode.
In this embodiment, the setting modes of the first indoor unit 20 include a cooling mode, a heating mode, a dehumidification mode, and an air supply mode, and the setting modes are factory default settings or user-set modes. After the first indoor unit 20 is turned on, one of the modes is operated.
The operation modes of the outdoor unit 10 include a cooling mode and a heating mode. The outdoor unit 10 is turned on and then operates in one of the modes.
It can be understood that the outdoor unit 10 operates in corresponding modes with the first indoor unit 20, so that the air conditioning system 100 is in different modes. Specifically, when both the outdoor unit 10 and the first indoor unit 20 operate in the cooling mode, the air conditioning system 100 is in the cooling mode, thereby cooling the indoor air. When both the outdoor unit 10 and the first indoor unit 20 operate the heating mode, the air conditioning system 100 is in the heating mode, thereby heating the indoor air. When the outdoor unit 10 operates in the cooling mode and the first indoor unit 20 operates in the dehumidification mode, the air conditioning system 100 is in the dehumidification mode, thereby reducing the humidity in the indoor air. When the outdoor unit 10 is turned off and only the fan of the first indoor unit 20 is operated, the air conditioning system 100 is in the air supply mode, thereby supplying air indoors.
Since the flow direction of the refrigerant is different in different modes due to the mode difference, the heating mode of the outdoor unit 10 conflicts with the cooling mode, the dehumidification mode, and the blowing mode of the first indoor unit 20, respectively, and the cooling mode of the outdoor unit 10 conflicts with the heating mode of the first indoor unit 20.
In this embodiment, when the setting mode of the first indoor unit 20 conflicts with the operation mode of the outdoor unit 10, for example, the first indoor unit 20 operates in the heating mode, and the outdoor unit 10 operates in the cooling mode, the outdoor unit 10 cannot cooperate with the refrigerant input corresponding to the first indoor unit 20, so that the first indoor unit 20 cannot operate according to the setting mode.
For this reason, when it is detected that the setting mode of the first indoor unit 20 conflicts with the operation mode of the outdoor unit 10, the first indoor unit 20 is controlled to be turned off. And when detecting that the setting mode of the first indoor unit 20 does not conflict with the operation mode of the outdoor unit 10, controlling the first indoor unit 20 to operate according to the current setting mode. In this way, the flow of the refrigerant in the air conditioning system 100 is prevented from being disturbed, which may cause damage to the air conditioning system 100.
For example, if the setting mode of the first indoor unit 20 and the operation mode of the outdoor unit 10 are both the cooling mode, the first indoor unit 20 is controlled to operate in the cooling mode. For example, if both the modes are heating modes, the first indoor unit 20 is controlled to operate in the heating mode. For another example, if the operation mode of the outdoor unit 10 is a cooling mode and the setting mode of the first indoor unit 20 is one of a cooling mode, a dehumidification mode and an air supply mode, the first indoor unit 20 is controlled to operate according to the corresponding setting mode.
S12, when the operation mode of the outdoor unit 10 is detected to be the heating mode, the second indoor unit 30 is controlled to be turned off.
S13, when the operation mode of the outdoor unit 10 is detected to be the non-heating mode, the second indoor unit 30 is controlled to operate according to the setting mode of the second indoor unit 30. The setting mode of the second indoor unit 30 is a non-heating mode.
In this embodiment, the setting mode of the second indoor unit 30 is a non-heating mode, and includes a cooling mode, a heating mode, a dehumidification mode, and an air blowing mode. After the second indoor unit 30 is turned on, one of the modes is operated according to default settings or user settings.
When the operation mode of the outdoor unit 10 is the heating mode, it is obvious that the second indoor unit 30 cannot operate any one of the cooling mode, the dehumidification mode, and the air supply mode that conflicts with the heating mode, otherwise, the two modes conflict with each other, which causes a flow direction disorder of the refrigerant in the air conditioning system 100, and causes damage to the air conditioning system 100.
When the operation mode of the outdoor unit 10 is the non-heating mode, the second indoor unit 30 may operate any one of a cooling mode, a dehumidification mode, and an air blowing mode to maintain the stability of the air conditioning system 100 by normalizing the flow of the refrigerant.
Therefore, when the operation mode of the outdoor unit 10 is detected to be the heating mode, the second indoor unit 30 is directly controlled to be turned off without detecting the setting mode of the second indoor unit 30. When the operation mode of the outdoor unit 10 is detected to be the non-heating mode, the setting mode of the second indoor unit 30 is detected, and the second indoor unit 30 is controlled to operate according to the setting mode.
Thus, after the air conditioning control method of the present embodiment is executed, the air conditioning system 100 has the following power-on states:
(1) the outdoor unit 10 operates in a cooling mode, the first indoor unit 20 operates in a cooling mode, and the second indoor unit 30 operates in any one of a cooling mode, a dehumidification mode, and an air supply mode;
(2) the outdoor unit 10 operates in a cooling mode, the first indoor unit 20 operates in a dehumidification mode, and the second indoor unit 30 operates in any one of a cooling mode, a dehumidification mode, and an air supply mode;
(3) the outdoor unit 10 operates in a cooling mode, the first indoor unit 20 operates in an air supply mode, and the second indoor unit 30 operates in any one of a cooling mode, a dehumidification mode, and an air supply mode;
(4) the outdoor unit 10 operates in a cooling mode, the first indoor unit 20 is turned off by operating in a heating mode, and the second indoor unit 30 operates in any one of a cooling mode, a dehumidifying mode, and an air supply mode;
(5) the outdoor unit 10 operates in the heating mode, the first indoor unit 20 operates in the heating mode, and the second indoor unit 30 is turned off;
(6) the outdoor unit 10 operates in the heating mode, the first indoor unit 20 is turned off by the cooling mode, and the second indoor unit 30 is turned off.
As can be seen from the above-mentioned on-state of the air conditioning system 100, when the outdoor unit 10 operates in the cooling mode, there are cases where both the first indoor unit 20 and the second indoor unit 30 are on (see the cases (1) to (3) for details), and there are cases where only the second indoor unit 30 is on (see the case (4) for details), which total 12 states. When the outdoor unit 10 operates in the heating mode, there are cases where only the first indoor unit 20 is turned on (see the case (5)) and cases where both the first indoor unit 20 and the second indoor unit 30 are turned off (see the case (6)), which total 2 states.
It can be understood that, by performing a hierarchical process on the first indoor unit 20 and the second indoor unit 30 and respectively executing preset control strategies on the first indoor unit and the second indoor unit, the setting modes of the first indoor unit and the second indoor unit do not conflict with the operation mode of the outdoor unit 10, and the setting modes of the first indoor unit and the second indoor unit do not conflict with each other, the flow direction of the refrigerant in the air conditioning system 100 is normal, and the normal operation of the system is ensured.
In summary, the air conditioner control method of the present embodiment detects whether the setting mode of the first indoor unit 20 conflicts with the operation mode of the outdoor unit 10, and if so, turns off the first indoor unit 20, and if not, controls the first indoor unit 20 to operate according to the current setting mode; and then, continuously detecting whether the working mode of the outdoor unit 10 is the heating mode, if so, controlling the second indoor unit 30 to be closed, and if not, controlling the second indoor unit 30 to operate according to the set mode. In this way, by performing hierarchical processing on the first indoor unit 20 and the second indoor unit 30, the complexity of controlling the plurality of indoor units is decoupled, so that each indoor unit can operate independently and also can work in cooperation with other indoor units, and there is no conflict between modes, thereby effectively preventing control confusion of the air conditioning system 100 and affecting unit reliability.
Referring to fig. 3, in one embodiment, before step S10 and step S11, the method further includes the following steps:
s14, when the outdoor unit 10 is turned on, determining the operation mode of the outdoor unit 10.
The operation modes of the outdoor unit 10 include a cooling mode and a heating mode. After determining the operation mode of the outdoor unit 10, it is detected whether the setting mode of the first indoor unit 20 conflicts with the operation mode of the indoor unit.
S15, when detecting that the outdoor unit 10 is turned off, controlling the outdoor unit 10 to be turned on.
The user operates the outdoor unit 10 to power on as required, so that the outdoor unit 10 is turned on.
Similarly, in an embodiment, before step S10 and step S11, the method further includes the following steps:
it is detected whether the first indoor unit 20 is turned on.
If the outdoor unit is turned on, determining whether the setting mode of the first indoor unit 20 conflicts with the working mode of the outdoor unit 10; if the indoor unit is not turned on, the first indoor unit 20 is controlled to maintain the off state or the standby state.
Therefore, the on state of the first indoor unit 20 includes three types: normal operation after starting up, forced closing after starting up and no starting up all the time.
Similarly, in an embodiment, before step S12 and step S13, the method further includes the following steps:
it is detected whether the second indoor unit 30 is turned on.
If the outdoor unit is started, judging whether the working mode of the outdoor unit 10 is a heating mode; if the indoor unit is not turned on, the second indoor unit 30 is controlled to keep the off state or the standby state.
Therefore, the on state of the second indoor unit 30 includes three types: normal operation after starting up, forced closing after starting up and no starting up all the time.
Referring to fig. 4, in one embodiment, the method further includes the following steps:
s16, when detecting that the first indoor unit 20 is not connected to the outdoor unit 10, controlling the first indoor unit 20 to be closed.
S17, when the first indoor unit 20 and the outdoor unit 10 are detected to be online, it is detected whether the setting mode of the first indoor unit 20 conflicts with the operation mode of the outdoor unit 10.
S18, controlling the second indoor unit 30 to be closed when detecting that the second indoor unit 30 is not connected to the outdoor unit 10.
S19, when the second indoor unit 30 is detected to be connected to the outdoor unit 10, it is detected whether the operation mode of the outdoor unit 10 is the heating mode.
In this embodiment, before the mode conflict detection step, the online states of the first indoor unit 20 and the second indoor unit 30 are detected respectively.
If detecting that the first indoor unit 20 is not connected to the outdoor unit 10, controlling the first indoor unit 20 to be closed; if the connection is detected, it is detected whether the setting mode of the first indoor unit 20 conflicts with the operation mode of the outdoor unit 10 to determine whether to control the operation of the first indoor unit 20.
And if the second indoor unit 30 is not connected with the outdoor unit 10, controlling the second indoor unit 30 to be closed. If the connection is detected, it is detected whether the operation mode of the outdoor unit 10 is the heating mode, so as to determine whether to control the operation of the second indoor unit 30.
Referring to fig. 5, in one embodiment, referring to fig. 2, the first indoor unit 20 passes through the first expansion valve EEVAConnected to the outdoor unit 10, a first expansion valve EEVAFor controlling the flow rate of the refrigerant entering the first indoor unit 20. The method further comprises the following steps:
s102, when the conflict between the setting mode of the first indoor unit 20 and the operation mode of the outdoor unit 10 is detected, controlling the first expansion valve EEVAIn the closed state.
S112, controlling the first expansion valve EEV when detecting that the setting mode of the first indoor unit 20 does not conflict with the operation mode of the outdoor unit 10AIn the open state.
Taking the air conditioning system 100 of fig. 2 as an example, if the first expansion valve EEV is in the cooling mode when the air conditioning system 100 is in the cooling modeAIn the open state, the air conditioning system 100 controls the compressor 101 to operate, so that the high-pressure gaseous refrigerant discharged from the compressor 101 enters the condenser 103 through the D-C nozzle of the four-way valve 102 to be liquefiedCondensing into high-pressure liquid refrigerant, and passing the high-pressure liquid refrigerant through a first expansion valve EEVAAnd a first liquid valve 104, which flows through the first indoor unit 20 to perform vaporization and heat absorption to form refrigeration, and finally, the refrigerant is collected into the air pipe assembly of the first indoor unit 20, and after passing through a first air valve 105 of the outdoor unit 10, the refrigerant returns to the suction port of the compressor 101 from the E pipe to the S pipe of the four-way valve 102, thereby forming the whole refrigeration cycle.
If the first expansion valve EEVAIn the closed state, the refrigerant passes through the condenser 103 of the outdoor unit 10 and then stops at the first expansion valve EEVAAnd the first indoor unit 20 cannot be entered, the refrigeration cycle is interrupted. At this time, the first indoor unit 20 cannot cool the indoor air.
If the first expansion valve EEV is in the heating mode when the air conditioning system 100 is in the heating modeAIn the open state, the air conditioning system 100 controls the operation of the compressor 101 and the four-way valve 102 to be powered on, and the high-pressure gaseous refrigerant discharged from the compressor 101 flows from the first air valve 105 of the outdoor unit 10 to the first indoor unit 20 through the D-E nozzle of the four-way valve 102. The high-pressure gaseous refrigerant exchanges heat in the first indoor unit 20 and is condensed into a liquid refrigerant, and then the liquid refrigerant flows into the first liquid valve 104 of the outdoor unit 10 through the indoor unit via the connecting pipe and passes through the first expansion valve EEV of the outdoor unit 10AThrottling and depressurizing into low-pressure liquid refrigerant. The low-pressure liquid refrigerant passes through the outdoor condenser 103 and turns into a gas state, and returns to the suction port of the compressor 101 from the pipe C to the pipe S of the four-way valve 102, thereby forming the entire heating cycle.
If the first expansion valve EEVAIn the closed state, the liquid refrigerant cannot enter the outdoor condenser 103 through the first liquid valve 104 of the outdoor unit 10 to be evaporated, and the heating cycle is interrupted. At this time, the first indoor unit 20 cannot heat the indoor air.
Thus, by controlling the first expansion valve EEVAThe open/close state of the first indoor unit 20 can be controlled to be operated or closed according to whether the modes conflict with each other, and the control method is simple and easy to implement.

s20, when it is detected that the second indoor unit 30 is turned off and the setting mode of the first indoor unit 20 is updated, controlling the first indoor unit 20 to operate according to the updated setting mode.
When the first indoor unit 20 is operated, the user can update the current setting mode of the first indoor unit to meet the requirement of comfortable temperature adjustment. The setting mode after the update is any one of the modes excluding the setting mode before the update. For example, if the setting mode before update is the heating mode, the setting mode after update is one of the cooling mode, the dehumidification mode, and the air blowing mode. For another example, if the setting mode before update is the cooling mode, the setting mode after update is one of the heating mode, the dehumidification mode, and the air blowing mode.
As can be seen from the above-mentioned on-state of the air conditioning system 100, the on-state of the second indoor unit 30 includes three types: normal operation after starting up, forced closing after starting up and no starting up all the time.
