In the embodiment provided by the invention, in the networking air exchange process of the air conditioning system, a first air conditioner is used for exhausting air from the indoor to the outdoor, and a second air conditioner is used for exhausting air from the outdoor to the indoor. When the number of the air conditioners in the air conditioning system is large, and the number of the first air conditioners and the number of the second air conditioners are large, the plurality of first air conditioners can be divided into a first air conditioner group, and the plurality of second air conditioners can be divided into a second air conditioner group, namely, the air conditioners in the first air conditioner group are used for exhausting air from the indoor to the outdoor, and the air conditioners in the second air conditioner group are used for sucking air from the outdoor to the indoor.
As shown in fig. 1, a flow chart of a control method for an air conditioning system including a plurality of air conditioners installed in different areas of an indoor space according to an exemplary embodiment is provided, the method including:
step S101 detects an indoor temperature.
And S102, when the indoor temperature meets the set conditions, controlling one or more first air conditioners in the plurality of air conditioners to discharge air from the indoor to the outdoor, and controlling one or more second air conditioners in the plurality of air conditioners to suck air from the outdoor to the indoor.
In the cooling mode, the indoor temperature is lower than the outdoor temperature, and the temperature of air sucked from the outdoor is high, and the indoor temperature is increased by mixing with the indoor air. When the indoor temperature is lower than the target temperature, the air-conditioning refrigeration effect meets the requirement of a user on refrigeration, the temperature is required to be increased when the temperature is lower than the requirement of the user, at the moment, the air-conditioning system enters the networking for air exchange, the air exchange requirement is met, the indoor temperature is correspondingly adjusted, and the refrigeration effect is guaranteed.
Similarly, in the heating mode, the indoor temperature is higher than the outdoor temperature, and the temperature of the air sucked from the outdoor is low, and the air is mixed with the indoor air to cause the indoor temperature to be lowered. When the indoor temperature is higher than the target temperature, the heating effect of the air conditioner meets the requirement of a user for heating, the temperature is higher than the requirement of the user, the temperature needs to be reduced, at the moment, the air conditioning system enters the networking for air exchange, the air exchange requirement is met, the indoor temperature is correspondingly adjusted, and the heating effect is guaranteed.
When the indoor temperature accords with the conditions, the air conditioning system enters the network and changes air, and the method mainly comprises the following steps: the air conditioning system is controlled such that one or more first air conditioners among the plurality of air conditioners discharge air from the room to the outside and one or more second air conditioners among the plurality of air conditioners draw air from the outside to the room.
The embodiment of the invention detects the indoor temperature in real time, controls the networking of the plurality of air conditioners when the indoor temperature meets the set condition, and cooperatively controls the running states of the plurality of air conditioners to realize air exchange, and the plurality of air conditioners cooperatively work, thereby enhancing the flow quantity of indoor air, ensuring the effectiveness of air exchange and reducing the influence on the cooling or heating effect.
Fig. 2 is a flowchart illustrating a control method for an air conditioner according to an exemplary embodiment, including:
step S201 detects an indoor temperature.
And step S202, controlling the air conditioner to exhaust air from the indoor to the outdoor or controlling the air conditioner to suck air from the outdoor to the indoor when the indoor temperature meets the set conditions.
In step S202, the air conditioner is controlled to discharge air from the room to the outside, or the air conditioner is controlled to suction air from the outside to the room.
In some optional embodiments, when the fan used by the air conditioner is a centrifugal fan or a cross-flow fan, the air conditioner is controlled to exhaust air from the indoor to the outdoor or control the air conditioner to suck air from the outdoor to the indoor by switching the air suction duct or the air exhaust duct.
In some optional embodiments, when the fan used by the air conditioner is an axial flow fan, the air conditioner is controlled to discharge air from the indoor to the outdoor by controlling the forward rotation or the reverse rotation of the fan, or the air conditioner is controlled to suck air from the outdoor to the indoor.
In the embodiment, the method is mainly used for controlling one air conditioner in the air conditioning system, when the indoor temperature meets the set condition, the air conditioner is controlled to exhaust air from the indoor to the outdoor, or the air conditioner is controlled to suck air from the outdoor to the indoor and is cooperated with other air conditioners to realize air exchange, and the plurality of air conditioners are cooperated to work, so that the flow quantity of indoor air is enhanced, the effectiveness of air exchange is ensured, and the influence on the refrigerating or heating effect is reduced.
In the above embodiment, the plurality of air conditioners of the air conditioning system are installed in different indoor areas, and the control method is mainly used for controlling the plurality of indoor air conditioners to cooperatively work to realize indoor air exchange, and when the indoor air exchange is realized, the air conditioner needs to suck air from the outdoor to the indoor and the air conditioner needs to exhaust air from the indoor to the outdoor. Because the indoor air temperature is different from the external temperature, the air sucked from the outdoor in the air exchange process can influence the refrigeration or heating effect of the air conditioner, and therefore the condition of starting networking air exchange is set for avoiding the influence of the air exchange on the refrigeration or heating effect of the air conditioner. Specifically, the setting conditions include: in the cooling mode, the indoor temperature is lower than the target temperature; alternatively, in the heating mode, the indoor temperature is greater than the target temperature.
In some optional embodiments, before controlling the air conditioner to exhaust air from the indoor to the outdoor, or before controlling the air conditioner to suck air from the outdoor to the indoor, the method further comprises: detecting the temperature of an air outlet of the air conditioner; and when the temperature of the air outlet of the air conditioner meets the preset condition, reducing the rotating speed of the fan of the air conditioner.
In some optional embodiments, the temperature of the air outlet meeting the preset condition includes: in the refrigeration mode, the temperature of the air outlet is higher than the set temperature; or, in the heating mode, the temperature of the air outlet is lower than the set temperature.
The set temperature is a temperature value set before leaving a factory and is prestored in the air conditioning system, or the set temperature is related to the average value of the air conditioning target temperature, and the larger the average value of the air conditioning target temperature is, the larger the value of the set temperature is. Optionally, the set temperature value corresponding to each air conditioner in the air conditioning system is the same. And the average value of the air-conditioning target temperatures is the average value of all the air-conditioning target temperatures in the air-conditioning system. The target temperature of the air conditioner is set by a user through a remote controller or other mobile terminals with remote control functions on the air conditioner. The set temperature is determined according to the average value of the target temperature of the air conditioner, so that the effectiveness of air exchange of the air conditioner network is guaranteed, and the user experience is improved.
In some alternative embodiments, the set temperature is determined according to the following equation:
T＝T’+a
wherein T is a set temperature, T' is an average value of the air-conditioning target temperature, and a is a temperature correction value; in a refrigeration mode, a ranges from 0.5 ℃ to 2 ℃, preferably, a ranges from 0.5 ℃, 1 ℃, 1.5 ℃ or 2 ℃; in the heating mode, a ranges from-2 ℃ to-0.5 ℃, preferably, a ranges from-2 ℃, 1.5 ℃, 1 ℃ or 0.5 ℃.
Since the indoor temperature is lower than the outdoor temperature in the cooling mode and the temperature of the air sucked from the outdoor is high, the temperature of the air mixed with the indoor air may cause the indoor temperature to be increased, and similarly, the indoor temperature is higher than the outdoor temperature in the heating mode and the temperature of the air sucked from the outdoor is low, the temperature of the air mixed with the indoor air may cause the indoor temperature to be decreased. The air change of the network can affect the refrigeration or heating efficiency of the air conditioner after long-time operation, so that the rotating speed of the fan is adjusted according to the temperature of the air outlet, the air exchange amount of the air is adjusted, and the influence of the air change on the refrigeration or heating effect of the air conditioner is further avoided.
In some optional embodiments, before reducing the fan speed of the air conditioner, the method further comprises: judging whether the rotating speed of the fan is greater than a set value or not; if so, the fan speed is reduced.
In the cooling or heating mode, the fluctuation of the indoor temperature is caused by the air sucked from the outdoor, and the rotating speed of the fan of the air conditioner needs to be adjusted to avoid human discomfort caused by overlarge fluctuation of the room temperature. When the indoor air pressure is larger than the outdoor air pressure, outdoor air cannot enter the room, or the indoor air pressure is smaller than the outdoor air pressure, and indoor air cannot be discharged outdoors, the air exchange efficiency can be reduced.
Fig. 3 is a flowchart illustrating a control method for an air conditioning system for determining whether an air conditioner exhausts air from the indoor to the outdoor or sucks air from the outdoor to the indoor according to an exemplary embodiment, including:
in step S301, one or more operating parameters of each air conditioner are obtained.
Step S302, setting the air conditioner meeting the preset condition as a first air conditioner, and setting the remaining air conditioners as second air conditioners.
In step S301, the operating parameters include the maximum air volume, or the maximum fan speed, or the maximum air volume and the maximum fan speed. The plurality of air conditioners are classified according to preset conditions.
In this embodiment, to ensure the coordinated operation among a plurality of air conditioners, the plurality of air conditioners in the air conditioning system are classified according to one or more working parameters of each air conditioner, and the functional responsibility of each air conditioner is determined, so as to ensure that the air suction volume and the air discharge volume are balanced in the process of realizing air exchange by the cooperative work of the plurality of air conditioners, thereby reducing the pressure difference of indoor air and improving the user experience.
In step S302, a selectable manner of setting the air conditioner meeting the preset condition as the first air conditioner includes: the air conditioner in which the highest fan rotation speed is the maximum is set as the first air conditioner. When a plurality of air conditioners with the maximum fan rotating speed are provided, the air conditioner with the maximum highest air volume is set as a first air conditioner.
Another optional manner of setting the air conditioner meeting the preset condition as the first air conditioner includes: and setting the air conditioner with the maximum highest air volume as a first air conditioner. When a plurality of air conditioners with the maximum air volume are provided, the air conditioner with the maximum fan rotating speed is set as a first air conditioner.
The air conditioner with the maximum rotating speed of the highest fan or the air conditioner with the maximum air volume is selected as the first air conditioner to exhaust air from the indoor to the outdoor, so that the dynamic balance of the air volume during air suction and exhaust can be ensured, the indoor pressure difference is reduced, and discomfort of a human body is avoided.
In the networking air exchange process of the air conditioning system, the second air conditioners suck air from the outside to the inside, the first air conditioners exhaust air from the inside to the outside, the air conditioner with the highest fan rotating speed as the maximum is set as the first air conditioner, the rest of the air conditioners serve as the second air conditioners, the number of the first air conditioners is smaller than or equal to that of the second air conditioners, in order to guarantee balance of air suction and exhaust, the fan rotating speed of the first air conditioner is consistent with the total fan rotating speed of one or more second air conditioners, when the plurality of second air conditioners exist, the air suction volume is divided equally by the plurality of second air conditioners, disturbance of air around air outlets of the second air conditioners is reduced when the second air conditioners suck air from the outside to the inside of the room, and user experience is enhanced.
In the embodiment of the present invention, the air conditioning system includes a plurality of air conditioners installed in different areas of the room, and the number of the air conditioners is selectable, and in the foregoing embodiment, it is preferable that the air conditioning system is composed of 2 air conditioners, or is composed of 3 air conditioners.
