According to an embodiment of the present invention, a method for controlling an air conditioner is provided, as shown in fig. 1, which is a schematic flow chart of an embodiment of the method of the present invention. The control method of the air conditioner may include: step S110 to step S140.
At step S110, it is determined whether the air conditioner is operating in a cooling mode, and if the air conditioner is operating in the cooling mode, the indoor ambient temperature and the indoor ambient humidity of the room where the air conditioner is located are obtained in the cooling mode of the air conditioner.
Specifically, during actual use, it may be determined whether the operation mode of the air conditioner is the cooling mode, and if the operation mode of the air conditioner is determined to be the cooling mode, the indoor ambient temperature and the indoor ambient humidity of the room where the air conditioner is located are obtained. For example: the current indoor loop temperature T is obtained through a temperature sensor of the indoor unit, and the current indoor environment humidity S is obtained through a humidity sensor of the indoor unit.
At step S120, it is determined whether a preset condensation prevention mode needs to be entered according to the indoor environment temperature and the indoor environment humidity, and if it is determined that a preset condensation prevention logic determination process needs to be entered, the air conditioner is controlled to enter the condensation prevention mode if the condensation prevention mode needs to be entered.
Specifically, the current indoor area temperature and the indoor environment humidity are determined, and whether the condensation prevention logic is entered is judged. And if the indoor environment temperature and the indoor environment humidity meet the conditions, entering anti-condensation logic.
In some embodiments, in step S120, a specific process of entering a preset anti-condensation mode is determined according to the indoor ambient temperature and the indoor ambient humidity, as described in the following exemplary description.
The following further describes a specific process of determining whether the preset anti-condensation mode needs to be entered in step S120, with reference to a flowchart of an embodiment of determining whether the preset anti-condensation mode needs to be entered in the method of the present invention shown in fig. 2, where the process includes: step S210 to step S230.
Step S210, determining whether the indoor ambient temperature is greater than or equal to a set temperature, and determining whether the indoor ambient humidity is greater than or equal to a set humidity.
Specifically, a determination is made based on the obtained indoor ambient temperature T and indoor ambient humidity S, and it is determined whether the indoor ambient temperature T is greater than or equal to a target temperature (e.g., 25 ℃), and whether the indoor ambient humidity S is greater than or equal to a target humidity (e.g., 76% relative humidity).
Step S220, if the indoor environment temperature is greater than or equal to the set temperature and the indoor environment humidity is greater than or equal to the set humidity, determining that the air conditioner needs to enter the condensation prevention mode, and controlling the air conditioner to enter the condensation prevention mode.
Specifically, when the indoor environment temperature T is greater than or equal to the target temperature, such as the indoor environment temperature T is greater than or equal to 25 ℃; and if the indoor environment humidity S is greater than or equal to the target humidity, if the indoor environment humidity S is greater than or equal to 76%, the anti-condensation logic judgment is started.
Step S230, if the indoor environment temperature is less than the set temperature and/or the indoor environment humidity is less than the set humidity, determining that the condensation prevention mode does not need to be entered, and continuously acquiring the indoor environment temperature and the indoor environment humidity of the room where the air conditioner is located in the cooling mode of the air conditioner, so as to re-determine whether the preset condensation prevention mode needs to be entered according to the continuously acquired indoor environment temperature and indoor environment humidity of the room where the air conditioner is located.
Specifically, when the indoor environment temperature T is less than 25 ℃ and/or the indoor environment humidity S is less than 76%, the anti-condensation logic judgment is not entered, that is, the current indoor environment temperature T and the current indoor environment humidity S are returned to be continuously obtained, so as to continuously judge whether the anti-condensation logic judgment needs to be entered.
From this, through the inner ring temperature (be indoor ambient temperature), the indoor ambient humidity based on the space that the air conditioner is located to utilize the comdenstion water flow of air conditioner condensate pipe, the formation rate of real-time supervision comdenstion water (be the comdenstion water flow), prevent the condensation and adjust with the formation rate of comdenstion water, be favorable to reducing the risk that the air conditioner appears blowing phenomenon (if the air-out wind channel of air conditioner has the drop of water to blow out).
At step S130, in the condensation prevention mode, a flow rate of condensation water in an evaporator condensation water pipe of the air conditioner is acquired.
In some embodiments, the obtaining of the flow rate of the condensed water in the condenser pipe of the evaporator of the air conditioner in step S130 includes: and acquiring the flow of condensed water in a condensed water pipe of the evaporator of the air conditioner, which is acquired by a flow detection module.
And the condensate pipe is arranged at a condensate outlet of a bottom shell of the air conditioner. The flow detection module is arranged in the condensate pipe. For example: the condensate pipe is arranged on the condensate pipe 3 of the bottom shell of the air conditioner. A flow meter, such as flow meter 2, is arranged in the condensate pipe 3.
Specifically, at the back of the air conditioner bottom case, a bottom case member 1 and a condensate pipe 3 are provided. In the condensate pipe 3, a flow meter 2 is provided. Namely, a condensate pipe 3 with a flowmeter 2 is connected at a condensate outlet of the air conditioner bottom shell. Through connecing flowmeter 2 on condensate pipe 3, satisfy the settlement condition when indoor temperature and humidity, through control condensate flow, control compressor frequency and electronic expansion valve opening reduce the evaporimeter superheat degree, reduce the condensation water yield, improve user's travelling comfort.
In some embodiments, the flow detection module comprises: a flow meter. The flowmeter is arranged at the joint of a condensate water outlet of the air conditioner and the condensate water pipe.
Specifically, a condensed water flow meter is added at the joint of the air conditioner condensed water outlet and the condensed water pipe 3. When the condensate water flow X meets the target value, the control process of preventing condensation enters, the current compressor running frequency is reduced, the opening of the electronic valve is increased, the superheat degree of the evaporator is reduced, the generation amount of the condensate water is reduced, the risk that water drops blow out from the air duct is reduced, and the comfort of a user is improved.
At step S140, it is determined whether anti-condensation control is required for the air conditioner according to the flow rate of the condensed water, so as to control at least one of an operating frequency of a compressor of the air conditioner and an opening degree of a throttling device of the air conditioner to realize the anti-condensation control for the air conditioner when the anti-condensation control for the air conditioner is required. Preferably, the condensation prevention control of the air conditioner may be implemented by controlling any one of an operation frequency of a compressor of the air conditioner and an opening degree of a throttle device of the air conditioner.
Specifically, under the condensation prevention logic, according to the condenser pipe flow, the current compressor running frequency and the electronic valve opening degree are adjusted, so that the condensate flow X is lower than a target value, the condensation water generation rate can be reduced, the risk that water drops blow out from an air channel is reduced, and the user comfort is improved.
Therefore, the air conditioner performs condensation prevention adjustment according to the inner ring temperature (namely, the indoor environment temperature), the indoor environment humidity and the flow of condensed water in the condensed water pipe by judging the inner ring temperature (namely, the indoor environment temperature) and the indoor environment humidity of the space where the air conditioner is located and arranging the flowmeter at the condensed water pipe. Like this, through the inner ring temperature (be indoor ambient temperature), the indoor ambient humidity based on the space that the air conditioner is located to prevent the condensation with the formation rate of real-time comdenstion water and adjust, rather than singly prevent the condensation through evaporimeter pipeline temperature and adjust, make the accuracy of preventing the condensation and adjusting higher, prevent that the condensation effect is better.
In some embodiments, a specific process of determining whether the anti-condensation control of the air conditioner is required according to the condensed water flow rate in step S140 is described in the following exemplary description.
The following further describes, with reference to a schematic flow chart of an embodiment of determining whether the anti-condensation control is required for the air conditioner in the method of the present invention shown in fig. 3, a specific process of determining whether the anti-condensation control is required for the air conditioner in step S140, including: step S310 to step S330.

Specifically, in the process of the anti-condensation logic judgment, the condensate water flow X in the condensate water pipe of the current evaporator is obtained, and if the condensate water flow X meets the set flow, if the condensate water flow X is larger than or equal to 0.5cm3And/s, judging that the current condensation water generation rate is higher, and the risk of condensation water dropping or blowing out exists, and performing anti-condensation regulation, such as reducing the current operation frequency of the compressor and increasing the opening degree of a throttling device (such as an electronic expansion valve) to reduce the superheat degree of the evaporator and reduce the condensate water generation rate, and stopping the anti-condensation regulation until the condensate water flow X does not meet the set flow.
In some embodiments, the controlling at least one of an operating frequency of a compressor of the air conditioner and an opening degree of a throttling device of the air conditioner in step S140 includes: the method comprises the steps of reducing the running frequency of a compressor of the air conditioner and/or increasing the opening degree of a throttling device of the air conditioner. Wherein, throttling arrangement includes: an electronic expansion valve.

When the condensation prevention adjustment is carried out, the current running speed of the compressor can be controlled to be reduced, so that the temperature of the inner tube of the evaporator is increased, the temperature difference between the temperature of the tube of the evaporator and the humid air is reduced, and the condensate water generation speed is reduced. When the condensation prevention adjustment is carried out, the current opening degree of a throttling device (such as an electronic valve opening degree) can be controlled to be increased, the throttling effect of the throttling device is reduced, the temperature of an inner pipe of the evaporator is increased, the temperature difference between the temperature of the evaporator pipe and the temperature of humid air is reduced, and the condensate water generation rate is reduced.

Since the processes and functions implemented by the apparatus of this embodiment substantially correspond to the embodiments, principles and examples of the method shown in fig. 1 to 3, the description of this embodiment is not detailed, and reference may be made to the related descriptions in the foregoing embodiments, which are not repeated herein.
Through a large number of tests, the technical scheme of the invention is adopted, under the condition that the indoor environment temperature and the indoor environment humidity of a room where the air conditioner is located reach the condensation prevention control condition in the refrigeration mode of the air conditioner, at least one of the running frequency of a compressor of the air conditioner and the opening degree of a throttling device (such as an electronic expansion valve) of the air conditioner is controlled according to the flow rate of condensed water in a condensed water pipe, so that the condensation prevention control of the air conditioner is realized, the generation amount of condensed water can be reduced, the risk of water drops blowing out of an air duct is reduced, and the comfort of a user is improved.
According to an embodiment of the present invention, there is also provided an air conditioner corresponding to a control device of the air conditioner. The air conditioner may include: the control device of the air conditioner described above.
The condensation mechanism is that when unsaturated wet air in a certain state is cooled or contacted with a certain cold surface, when the temperature of the wet air is reduced to the dew point temperature or below the dew point temperature, the wet air reaches a saturated state, redundant moisture contained in the wet air is separated out, and the condensation phenomenon occurs, and the condensation phenomenon is mainly expressed in the form that water drops are condensed on the surface of an air conditioning structure or the wet air is blown out from an air duct.
In the related art, the condensation prevention technology of an air conditioner (i.e., an air conditioner) mainly adjusts the temperature of an evaporator pipeline, for example, when the temperature of the evaporator pipeline is lower than a set value, the frequency of a compressor is reduced, so as to prevent the temperature of the evaporator pipeline from being too low. However, in practice, the dew point temperature of the humid air varies depending on the indoor ambient temperature and humidity, and the adjustment based on the temperature of the evaporator inner tube alone is not comprehensive. Specifically, under the condition of the same temperature, the higher the humidity is, the easier the condensation is, on the contrary, the lower the humidity is, the harder the condensation is, the single adjustment is performed through the evaporator pipeline temperature, the different dew point temperatures and the evaporator pipeline temperature set values corresponding to different temperatures and humidities are difficult to cover comprehensively, and the condensation prevention effect is poor.
In some embodiments, according to an aspect of the present invention, there is provided an anti-condensation control method for an air conditioner, in which a flow meter is disposed at a condensate pipe (for example, a flow meter is disposed in the condensate pipe), and under an anti-condensation logic of the air conditioner, the air conditioner performs anti-condensation adjustment according to a flow rate of the condensate pipe (for example, the air conditioner adjusts a frequency of a compressor or a target exhaust superheat degree according to a flow rate value of the condensate pipe), so that an amount of generated condensation water can be reduced, a risk of water drops blowing out in an air duct can be reduced, and user comfort can be improved. The target degree of superheat of the discharge gas is a target discharge gas temperature for system operation, and is not a target degree of superheat of the discharge gas of the compressor.
Specifically, in the scheme of the invention, by judging the inner ring temperature (namely, the indoor environment temperature) and the indoor environment humidity of the space where the air conditioner is located, the flowmeter is arranged at the condensate pipe, and the air conditioner performs condensation prevention regulation according to the inner ring temperature (namely, the indoor environment temperature), the indoor environment humidity and the flow of condensate water in the condensate pipe.
Like this, based on the inner ring temperature (be indoor ambient temperature), the indoor ambient humidity in the space that the air conditioner is located to utilize the comdenstion water flow of air conditioner condenser pipe, the formation rate of real-time supervision comdenstion water (be the comdenstion water flow), prevent the condensation and adjust with the formation rate of comdenstion water, be favorable to reducing the risk that the air conditioner appears blowing phenomenon (if the air-out wind channel of air conditioner has the drop of water to blow out). Through the inner ring temperature (be indoor ambient temperature), the indoor ambient humidity based on the space that the air conditioner is located to prevent the condensation with the formation rate of real-time comdenstion water and adjust, and the non-single condensation of preventing adjusts through evaporimeter pipeline temperature, makes the accuracy of preventing the condensation and adjusting higher, and it is better to prevent the condensation effect.
Furthermore, in the scheme of the invention, the current indoor area temperature and the indoor environment humidity are determined, and whether the current indoor area temperature and the current indoor environment humidity enter the condensation prevention logic is judged; if the indoor environment temperature and the indoor environment humidity meet the conditions, entering anti-condensation logic; under the condensation prevention logic, the current compressor running frequency and the electronic valve opening degree are adjusted according to the flow of the condensate pipe, so that the condensate flow X is lower than a target value, the condensation water generation rate can be reduced, the risk that water drops blow out from an air channel is reduced, and the user comfort is improved. For example: when the condensate water flow X meets the target value, the condensate water enters the anti-condensation control process, the current compressor running frequency is reduced, the opening of the electronic valve is increased, the superheat degree of the evaporator is reduced, the condensate water generation rate is reduced, the risk that water drops blow out from the air duct is reduced, and the user comfort is improved. Under the condition that other conditions are the same, the target exhaust temperature of the system operation is reduced, the superheat degree of the evaporator is also reduced, and the condensation water generation rate is favorably reduced.

Fig. 5 is a schematic structural diagram of an embodiment of the back surface of the bottom case of the air conditioner. Fig. 6 is a partial enlarged structural schematic diagram of a part B in fig. 5, specifically, a partial enlarged structural schematic diagram of a condensed water outlet of an air conditioner bottom case after being connected with a condensed water pipe with a flow meter.
As shown in fig. 5 and 6, a bottom case member 1 and a condensate pipe 3 are provided on the back of the air conditioning bottom case. In the condensate pipe 3, a flow meter 2 is provided. Namely, a condensate pipe 3 with a flowmeter 2 is connected at a condensate outlet of the air conditioner bottom shell. More specifically, a condensed water flowmeter is added at the joint of the air conditioner condensed water outlet and the condensed water pipe 3.
The bottom shell component 1 refers to a general assembly integrated with the bottom structure of the air conditioner. For example: the whole parts of an air conditioner air duct, a cross-flow fan blade assembly, a motor assembly, a controller electrical box assembly and the like are called as a bottom shell component 1. The condensed water pipe is connected with the condensed water outlet of the bottom shell component.
Therefore, in the scheme of the invention, the flow meter 2 is connected to the condensate pipe 3, when the indoor temperature and humidity meet the set conditions, the frequency of the compressor and the opening degree of the electronic expansion valve are controlled by monitoring the flow rate of the condensate water, the superheat degree of the evaporator is reduced, the generation amount of condensed water is reduced, and the comfort of a user is improved.

step 1, acquiring the current indoor loop temperature T through a temperature sensor of an indoor unit, and acquiring the current indoor environment humidity S through a humidity sensor of the indoor unit.
And 2, judging according to the obtained indoor environment temperature T and the indoor environment humidity S, judging whether the indoor environment temperature T is greater than or equal to a target temperature (such as 25 ℃) or not, and judging whether the indoor environment humidity S is greater than or equal to a target humidity (such as 76% relative humidity) or not.
Step 3, when the indoor environment temperature T is greater than or equal to the target temperature, if the indoor environment temperature T is greater than or equal to 25 ℃; and if the indoor environment humidity S is greater than or equal to the target humidity, if the indoor environment humidity S is greater than or equal to 76%, the anti-condensation logic judgment is started. Certainly, when the indoor environment temperature T is less than 25 ℃ and/or the indoor environment humidity S is less than 76%, the anti-condensation logic judgment is not performed, that is, the step 1 is returned to continue to obtain the current indoor environment temperature T and the current indoor environment humidity S, so as to continue to judge whether the anti-condensation logic judgment needs to be performed.
Step 4, in the process of the anti-condensation logic judgment, acquiring the condensate water flow X in the condensate water pipe of the current evaporator, and if the condensate water flow X meets the set flow, if the condensate water flow X is more than or equal to 0.5cm3And/s, judging that the current condensation water generation rate is higher, and the risk of condensation water dropping or blowing out exists, and performing anti-condensation regulation, such as reducing the current operation frequency of the compressor and increasing the opening degree of a throttling device (such as an electronic expansion valve) to reduce the superheat degree of the evaporator and reduce the condensate water generation rate, and stopping the anti-condensation regulation until the condensate water flow X does not meet the set flow.
Specifically, when the flow X of the condensed water is greater than or equal to the set flow, for example, the flow X of the condensed water is greater than or equal to 0.5cm3And/s, judging that the air duct has the risk of water drops blowing out, and needing anti-condensation regulation. When the condensation prevention adjustment is carried out, the current running speed of the compressor can be controlled to be reduced, so that the temperature of the inner tube of the evaporator is increased, the temperature difference between the temperature of the tube of the evaporator and the humid air is reduced, and the condensate water generation speed is reduced. When the condensation prevention adjustment is carried out, the current opening degree of a throttling device (such as an electronic valve opening degree) can be controlled to be increased, the throttling effect of the throttling device is reduced, the temperature of an inner pipe of the evaporator is increased, the temperature difference between the temperature of the evaporator pipe and the temperature of humid air is reduced, and the condensate water generation rate is reduced.
Through comparing most products (like the air conditioner), only rely on evaporimeter inner tube temperature to adjust, it is relatively poor to prevent the condensation effect of air conditioner. According to the scheme of the invention, the condensed water flow (namely the condensed water generation rate of the indoor unit) is controlled, the accuracy is higher, the condensed water generation rate can be prevented from being reduced in advance according to the outflow rate of the condensed water in the condensed water pipe under the working condition of higher humidity, the risk of water drops blowing out of an air duct is reduced, and the user comfort is improved.
