Detailed Description
The embodiment firstly provides a control method of the wall-mounted air conditioner indoor unit, the wall-mounted air conditioner indoor unit operating in the heating mode can be reasonably and effectively adjusted by comprehensively considering the environment temperature and the heat exchanger temperature, and the working reliability of the wall-mounted air conditioner indoor unit is improved. Fig. 1 is a schematic diagram illustrating a method for controlling an indoor unit of a wall-mounted air conditioner according to an embodiment of the present invention. As shown in fig. 1, the control method of the wall-mounted air conditioner indoor unit may perform the following steps:
step S102, receiving a trigger signal of the heating mode of the indoor unit of the wall-mounted air conditioner and acquiring the set temperature of the indoor unit of the wall-mounted air conditioner;
step S104, detecting the ambient temperature at the diagonal position of the indoor unit of the wall-mounted air conditioner and the temperature of a heat exchanger of the indoor unit of the wall-mounted air conditioner;
step S106, judging whether the environmental temperature is smaller than the difference between the set temperature and the preset value or not, and the temperature of the heat exchanger is larger than or equal to the preset thermal protection temperature, if so, executing step S108;
and S108, adjusting the opening of an expansion valve of the wall-mounted air conditioner indoor unit so as to cool a heat exchanger of the wall-mounted air conditioner indoor unit.
In the above steps, step S102 receives the trigger signal for the wall-mounted air conditioner indoor unit to start the heating mode and obtains the set temperature of the wall-mounted air conditioner indoor unit, and specifically, the trigger signal for the wall-mounted air conditioner indoor unit to start the heating mode and the set temperature thereof can be obtained in various manners. For example, the information can be obtained through a remote controller, a display device, a voice device of the wall-mounted air conditioner indoor unit or a mobile terminal bound with the wall-mounted air conditioner indoor unit. The mobile terminal may be a smart device convenient to move, such as a smart phone, a tablet computer, and the like. Receiving a trigger signal for starting the heating mode of the indoor unit of the wall-mounted air conditioner means that the indoor unit of the wall-mounted air conditioner starts to operate in the heating mode.
And S104, detecting the ambient temperature at the diagonal position of the indoor unit of the wall-mounted air conditioner and the temperature of a heat exchanger of the indoor unit of the wall-mounted air conditioner, wherein temperature sensors can be arranged at the diagonal position of the indoor unit of the wall-mounted air conditioner and the position of the heat exchanger, so that the ambient temperature and the temperature of the heat exchanger can be detected through the corresponding temperature sensors. The heat exchanger temperature refers to the temperature of a heat exchanger in the wall air conditioner indoor unit, which operates as a condenser in the case where the wall air conditioner indoor unit is operating in the heating mode.
It should be noted that, generally, the wall-mounted air conditioner indoor unit may be disposed on one wall of the indoor environment, and a temperature sensor for detecting the ambient temperature may be disposed on the other wall opposite to the wall-mounted air conditioner indoor unit. And the temperature sensor and the wall-mounted air conditioner indoor unit can be in diagonal positions, namely the ambient temperature at a position far away from the wall-mounted air conditioner indoor unit is detected by the temperature sensor. In a preferred embodiment, the temperature sensor, in addition to being located diagonally to the wall mounted air conditioner indoor unit, may be located somewhat lower, i.e. it measures the ambient temperature at a higher location than that which is close to the wall mounted air conditioner indoor unit.
Since the generated hot air is automatically raised when the wall-mounted air conditioner indoor unit operates in the heating mode, the ambient temperature of the surrounding or upper area is easily raised, and the set temperature may be easily reached. But the whole temperature of the indoor environment may not meet the requirement, and whether the whole temperature distribution of the indoor environment is uniform can be accurately known by arranging the temperature sensor at the diagonal line of the indoor unit of the wall-mounted air conditioner, so that a foundation can be laid for accurately judging whether the indoor unit of the wall-mounted air conditioner is started for heat protection in the follow-up process.
Step S106 is to judge whether the ambient temperature is less than the difference between the set temperature and the preset value or not, and the temperature of the heat exchanger is greater than or equal to the preset thermal protection temperature, and if the judgment result is yes, namely the ambient temperature is less than the difference between the set temperature and the preset value, and the temperature of the heat exchanger is greater than or equal to the preset thermal protection temperature, step S108 is executed to adjust the opening degree of an expansion valve of the wall-mounted air conditioner indoor unit so as to cool the heat exchanger of the wall-mounted air conditioner indoor unit.
Because the heat protection is usually directly opened when the temperature of the heat exchanger reaches the preset heat protection temperature, the heat protection is easily and frequently opened, the heating quantity of the wall-mounted air conditioner indoor unit is reduced, and the heating effect of the wall-mounted air conditioner indoor unit is influenced. Some situations where thermal protection is turned on are often not necessary, for example, thermal protection due to insufficient heat circulation, which is caused by excessive local temperature above the indoor unit of the wall-mounted air conditioner due to the hot air circulating in the upper part.
This embodiment is less than the difference between settlement temperature and the default at ambient temperature to under the condition of heat exchanger temperature more than or equal to default thermal protection temperature, adjust the aperture of hanging air conditioner indoor unit's expansion valve, in order to cool down hanging air conditioner indoor unit's heat exchanger. Although the temperature of the heat exchanger reaches the preset thermal protection temperature, the ambient temperature at the diagonal line of the indoor unit of the wall-mounted air conditioner does not reach the difference between the set temperature and the preset value, which indicates that the temperature distribution of the indoor environment is uneven.
In a specific embodiment, the adjusting the opening degree of the expansion valve of the wall-mounted air conditioner indoor unit in step S108 may include: the opening degree of the expansion valve is controlled to be increased, and the flow rate of the refrigerant entering the heat exchanger is increased. The flow of the refrigerant entering the heat exchanger is increased, so that the heating capacity of the heat exchanger is increased, the hot air is promoted to enter the indoor environment to be fully circulated, the temperature distribution of the indoor environment is uniform, the gathering of a large amount of hot air above the indoor unit of the wall-mounted air conditioner can be avoided, the temperature rise of the heat exchanger caused by the fact that the hot air enters the heat exchanger through the air inlet can be avoided, and the temperature of the heat exchanger can be effectively reduced. The error reason causing the opening of the thermal protection is eliminated, the necessity of the opening of the thermal protection is ensured, and the times and frequency of the opening of the thermal protection are effectively reduced, so that the heating quantity and the heating effect of the indoor unit of the wall-mounted air conditioner are ensured.
The control method of the wall-mounted air conditioner indoor unit of the embodiment comprises the steps of receiving a trigger signal of a heating mode of the wall-mounted air conditioner indoor unit, obtaining a set temperature of the wall-mounted air conditioner indoor unit, detecting an ambient temperature at a diagonal position of the wall-mounted air conditioner indoor unit and a temperature of a heat exchanger of the wall-mounted air conditioner indoor unit, judging whether the ambient temperature is smaller than a difference between the set temperature and a preset value, judging whether the temperature of the heat exchanger is larger than or equal to a preset heat protection temperature, and adjusting the opening degree of an expansion valve of the wall-mounted air conditioner indoor unit under the condition that the ambient temperature and the temperature of the heat exchanger are the same, so as to cool the heat exchanger of the wall-mounted air conditioner indoor unit, reasonably and effectively adjust the wall-mounted air conditioner indoor unit operating in the heating mode by comprehensively considering the ambient temperature and the temperature of the heat exchanger, and improve the working reliability of the wall-mounted air conditioner indoor unit.
In some optional embodiments, the wall-mounted air conditioner indoor unit can achieve a higher technical effect by further optimizing and configuring the above steps, and the following describes in detail the control method of the wall-mounted air conditioner indoor unit of this embodiment in combination with a description of an optional execution flow of this embodiment. Fig. 2 is a detailed flowchart of a method for controlling a wall-mounted air conditioner indoor unit according to an embodiment of the present invention, which may include the following steps:
step S202, receiving a trigger signal of the wall-mounted air conditioner indoor unit for starting a heating mode and acquiring a set temperature of the wall-mounted air conditioner indoor unit;
step S204, detecting the ambient temperature at the diagonal position of the indoor unit of the wall-mounted air conditioner and the temperature of a heat exchanger of the indoor unit of the wall-mounted air conditioner;
step S206, judging whether the environmental temperature is less than the difference between the set temperature and the preset value, and the temperature of the heat exchanger is greater than or equal to the preset thermal protection temperature, if so, executing step S208, otherwise, executing step S210;
step S208, controlling the opening degree of the expansion valve to increase, and increasing the flow of the refrigerant entering the heat exchanger so as to cool the heat exchanger of the wall-mounted air conditioner indoor unit;
step S210, judging whether the environmental temperature is greater than or equal to the difference between the set temperature and the preset value, and the temperature of the heat exchanger is greater than or equal to the preset thermal protection temperature, if so, executing step S212, otherwise, executing step S214;
step S212, controlling the wall-mounted air conditioner indoor unit to start a thermal protection mode;
step S214, determining whether the ambient temperature is less than the difference between the set temperature and the preset value, and the heat exchanger temperature is less than the preset thermal protection temperature, if yes, performing step S218, and if no, performing step S216;
step S216, the ambient temperature is greater than or equal to the difference between the set temperature and the preset value, and the temperature of the heat exchanger is less than the preset thermal protection temperature;
and step S218, controlling the wall-mounted air conditioner indoor unit to keep the current heating mode unchanged.
In the above steps, step S202 and step S204 are first executed, a trigger signal for starting a heating mode of the wall-mounted air conditioner indoor unit is received, a set temperature of the wall-mounted air conditioner indoor unit is obtained, an ambient temperature at a diagonal position of the wall-mounted air conditioner indoor unit and a heat exchanger temperature of the wall-mounted air conditioner indoor unit are detected, then a difference between the ambient temperature and the set temperature and a preset value is compared, the heat exchanger temperature and a preset heat protection temperature are compared, and a working state of the wall-mounted air conditioner indoor unit is adjusted according to two comparison results.
Specifically, step S206 determines whether the ambient temperature is less than the difference between the set temperature and the preset value, and the heat exchanger temperature is greater than or equal to the preset thermal protection temperature, and if the determination result in step S206 is yes, that is, the ambient temperature is less than the difference between the set temperature and the preset value, and the heat exchanger temperature is greater than or equal to the preset thermal protection temperature, step S208 is executed to control the opening degree of the expansion valve to increase, and increase the flow rate of the refrigerant entering the evaporator, so as to cool the heat exchanger of the wall-mounted air conditioner indoor unit.
In this case, although the temperature of the heat exchanger reaches the preset thermal protection temperature, the ambient temperature at the diagonal of the wall-mounted air conditioner indoor unit does not reach the difference between the preset temperature and the preset value, which indicates that the temperature distribution of the indoor environment is not uniform, because the temperature of the heat exchanger rises due to the upper circulation of the hot air, the thermal protection is not directly started, but the opening degree of the expansion valve is controlled to increase, and the flow of the refrigerant entering the evaporator is increased, so as to cool the heat exchanger of the wall-mounted air conditioner indoor unit.
The flow of the refrigerant entering the heat exchanger is increased, so that the heating capacity of the heat exchanger is increased, the hot air is promoted to enter the indoor environment to be fully circulated, the temperature distribution of the indoor environment is uniform, the gathering of a large amount of hot air above the indoor unit of the wall-mounted air conditioner can be avoided, the temperature rise of the heat exchanger caused by the fact that the hot air enters the heat exchanger through the air inlet is avoided, and the temperature of the heat exchanger can be effectively reduced. The error reason causing the opening of the thermal protection is eliminated, the necessity of the opening of the thermal protection is ensured, and the times and frequency of the opening of the thermal protection are effectively reduced, so that the heating quantity and the heating effect of the indoor unit of the wall-mounted air conditioner are ensured.
If the determination result in step S206 is negative, step S210 is executed to determine whether the ambient temperature is greater than or equal to the difference between the set temperature and the preset value, and the heat exchanger temperature is greater than or equal to the preset thermal protection temperature. And if the judgment result in the step S210 is yes, that is, the ambient temperature is greater than or equal to the difference between the set temperature and the preset value, and the temperature of the heat exchanger is greater than or equal to the preset thermal protection temperature, the step S212 is executed to control the wall-mounted air conditioner indoor unit to start the thermal protection mode. Under the condition, the temperature of the heat exchanger reaches the preset thermal protection temperature, the ambient temperature at the diagonal line of the indoor unit of the wall-mounted air conditioner also reaches the difference between the set temperature and the preset value, which shows that the temperature distribution of the indoor environment is uniform, and the temperature of the heat exchanger is not increased due to the upper circulation of hot air, so that the indoor unit of the wall-mounted air conditioner can be controlled to start a thermal protection mode, and the situation that thermal protection is necessary to be started belongs to at the moment.
It should be noted that after the step of adjusting the opening degree of the expansion valve of the wall-mounted air conditioner indoor unit, that is, after the step of controlling the opening degree of the expansion valve to increase in step S208, the ambient temperature and the heat exchanger temperature may be detected again, and when the ambient temperature is greater than or equal to the difference between the set temperature and the preset value, and the heat exchanger temperature is greater than or equal to the preset thermal protection temperature, the wall-mounted air conditioner indoor unit is controlled to start the thermal protection mode. That is to say, if the opening degree of the expansion valve is controlled to be increased, the flow rate of the refrigerant entering the heat exchanger is increased, the temperature distribution is promoted to be uniform, and after the temperature of the heat exchanger is reduced, the condition of starting thermal protection is also achieved, then the indoor unit of the wall-mounted air conditioner can be controlled to start the thermal protection mode.
If the opening degree of the expansion valve is increased by controlling, the flow of the refrigerant entering the heat exchanger is increased, the temperature distribution is promoted to be uniform, after the temperature of the heat exchanger is reduced, the ambient temperature is more than or equal to the difference between the set temperature and the preset value, and the temperature of the heat exchanger is less than the preset thermal protection temperature, namely, under the condition that the indoor ambient temperature is uniformly distributed, the temperature of the heat exchanger does not reach the preset thermal protection temperature, and at the moment, the thermal protection opening condition is not reached, so that the thermal protection can be prevented from being opened.
In the case that the determination result in the step S210 is no, step S214 is executed to determine whether the ambient temperature is less than the difference between the set temperature and the preset value, and the heat exchanger temperature is less than the preset thermal protection temperature. And if the determination result in the step S214 is yes, that is, the ambient temperature is less than the difference between the set temperature and the preset value, and the temperature of the heat exchanger is less than the preset thermal protection temperature, the step S218 is executed to control the wall-mounted air conditioner indoor unit to maintain the current heating mode unchanged. Under the condition, the temperature of the heat exchanger does not reach the preset heat protection temperature, and the ambient temperature at the diagonal line of the wall-mounted air conditioner indoor unit does not reach the difference between the set temperature and the preset value, so that the heat protection does not need to be started, and the wall-mounted air conditioner indoor unit is controlled to keep the current heating mode unchanged.
Since the ambient temperature and the difference between the set temperature and the preset value are compared, and the heat exchanger temperature and the preset thermal protection temperature are compared, the total four comparison results are obtained, according to the step execution sequence shown in fig. 2, in the case that the determination result of the step S214 is negative, it can be determined without error that the ambient temperature is greater than or equal to the difference between the set temperature and the preset value, and the heat exchanger temperature is less than the preset thermal protection temperature, that is, the step S216 is executed. And, after step S216 is executed, step S218 may be executed to control the wall-mounted air conditioner indoor unit to maintain the current heating mode.
That is to say, under the condition that the ambient temperature is greater than or equal to the difference between the set temperature and the preset value and the temperature of the heat exchanger is less than the preset heat protection temperature, because the ambient temperature at the diagonal of the wall-mounted air conditioner indoor unit reaches the difference between the set temperature and the preset value, but the temperature of the heat exchanger does not reach the preset heat protection temperature, the heat protection does not need to be started, and the wall-mounted air conditioner indoor unit is controlled to keep the current heating mode unchanged. The wall-mounted air conditioner indoor unit is controlled to keep the current heating mode unchanged, namely, the heat protection is not required to be started or the rotating speed of an indoor fan is not required to be adjusted.
The step S212 of controlling the wall-mounted air conditioner indoor unit to turn on the thermal protection mode may include: and controlling the indoor unit of the wall-mounted air conditioner to be closed for a preset time length in the heating mode. And, can also after controlling hanging air conditioner indoor unit to close the mode of heating and predetermine the duration: and re-detecting the temperature of the heat exchanger, and controlling the wall-mounted air conditioner indoor unit to re-start the heating mode under the condition that the temperature of the heat exchanger is less than the preset thermal protection temperature.
That is to say, after controlling hanging air conditioner indoor unit to open the thermal protection mode, close the mode of heating promptly and predetermine for a long time, detect the heat exchanger temperature again, if the heat exchanger temperature is less than and predetermine the thermal protection temperature, explain no longer need carry out thermal protection, can control hanging air conditioner indoor unit to open the mode of heating again, continue to provide the heat to the indoor environment, satisfy user's comfort level demand.

If the set temperature is 23 c, the sensed ambient temperature is 22 c, and the heat exchanger temperature is 59 c, then it may be determined that the wall-mounted air conditioner indoor unit is in the thermal protection mode.
If the set temperature is 23 deg.c, the sensed ambient temperature is 20 deg.c and the heat exchanger temperature is 50 deg.c, then it may be determined that the wall-mounted air conditioner indoor unit remains in the current heating mode. If the set temperature is 23 c, the sensed ambient temperature is 20 c, and the heat exchanger temperature is 59 c, then it may be determined that the indoor fan of the wall-mounted air conditioner is increasing in speed.
In the control method of the wall-mounted air conditioner indoor unit according to the embodiment, when the ambient temperature is less than the difference between the set temperature and the preset value and the temperature of the heat exchanger is greater than or equal to the preset thermal protection temperature, the opening of the expansion valve is controlled to be increased, and the flow of the refrigerant entering the heat exchanger is increased, so that the heat exchanger of the wall-mounted air conditioner indoor unit is cooled; under the condition that the ambient temperature is less than the difference between the set temperature and the preset value and the temperature of the heat exchanger is less than the preset thermal protection temperature, or under the condition that the ambient temperature is greater than or equal to the difference between the set temperature and the preset value and the temperature of the heat exchanger is less than the preset thermal protection temperature, the wall-mounted air conditioner indoor unit is determined to keep the current heating mode unchanged; the difference between the set temperature and the preset value is achieved when the ambient temperature is larger than or equal to the difference between the set temperature and the preset value, and under the condition that the temperature of the heat exchanger is larger than or equal to the preset heat protection temperature, the heat protection mode of the wall-mounted air conditioner indoor unit is determined, the heat protection mode can be started according to the actual condition under the premise that the indoor ambient temperature is uniformly distributed, the wall-mounted air conditioner indoor unit is prevented from being easily and frequently started, the heating effect of the wall-mounted air conditioner indoor unit is effectively guaranteed, and the comfort level experience of a user is improved.

The control program 221 may be downloaded from a computer-readable storage medium to a corresponding computing/processing device or downloaded and installed to the control apparatus 200 via a network (e.g., the internet, a local area network, a wide area network, and/or a wireless network).
Fig. 4 is a schematic diagram of an overall structure of the wall-mounted air conditioner indoor unit 100 according to an embodiment of the present invention. The wall-mounted air conditioner indoor unit 100 may have the control device 200 of the wall-mounted air conditioner indoor unit of the above embodiment. That is, the control device 200 of the wall-mounted air conditioner indoor unit may be disposed on the wall-mounted air conditioner indoor unit 100 instead of being disposed outside the wall-mounted air conditioner indoor unit 100.
As shown in fig. 4, the wall-mounted air conditioner indoor unit 100 of the present embodiment may include: a housing 110, and an air outlet 111 may be provided below the housing 110. Specifically, the interior of the housing 110 defines a cavity in which an indoor fan and a heat exchanger may be disposed. When the wall-mounted air conditioner indoor unit 100 operates in the heating mode, the heat exchanger in the cavity operates as a condenser, and the indoor fan can send hot air after heat exchange by the heat exchanger to the indoor environment through the air outlet 111. In addition, the air outlet 111 can be further provided with a transverse guide plate 112 and a vertical guide plate, wherein the vertical guide plate can adjust left and right air outlet, and the transverse guide plate 112 can adjust up and down air outlet.
In the method for controlling the wall-mounted air conditioner indoor unit in the above embodiment, when the ambient temperature is less than the difference between the set temperature and the preset value, and the temperature of the heat exchanger is greater than or equal to the preset thermal protection temperature, the opening degree of the expansion valve is controlled to increase the flow rate of the refrigerant entering the heat exchanger, so as to cool the heat exchanger of the wall-mounted air conditioner indoor unit 100. Although the temperature of the heat exchanger reaches the preset thermal protection temperature, since the ambient temperature at the diagonal line of the wall-mounted air conditioner indoor unit 100 does not reach the difference between the preset temperature and the preset value, it indicates that the temperature distribution of the indoor environment is not uniform, and the temperature of the heat exchanger is increased due to the upper circulation of the hot air. In the case where the temperature of the heat exchanger rises due to the upper circulation of the hot air, the thermal protection is not directly turned on, but the flow rate of the refrigerant entering the heat exchanger is increased by controlling the opening degree of the expansion valve to increase, so as to cool the heat exchanger of the wall-mounted air conditioner indoor unit 100.
The flow of the refrigerant entering the heat exchanger is increased, so that the heating capacity of the heat exchanger is increased, the hot air is promoted to enter the indoor environment to fully circulate, the temperature distribution of the indoor environment is uniform, the gathering of a large amount of hot air above the wall-mounted air conditioner indoor unit 100 can be avoided, the temperature rise of the heat exchanger caused by the fact that the hot air enters the heat exchanger through the air inlet can be avoided, and the temperature of the heat exchanger can be effectively reduced.
In other embodiments, other measures can be used to promote even distribution of the indoor ambient temperature and reduction of the temperature of the heat exchanger without having to turn on the thermal protection. For example, the rotational speed of an indoor fan of the wall-mounted air conditioner indoor unit 100 may be controlled to be increased. The air flow rate is increased by increasing the rotating speed of the indoor fan, so that the air flow of indoor environment is accelerated, the uniform temperature distribution can be promoted, and the temperature of the heat exchanger is reduced.
For another example, the posture of the transverse guide plate 112 can be adjusted to allow the wall-mounted air conditioner indoor unit 100 to blow air downward. The wall-mounted air conditioner indoor unit 100 can blow air downwards, a large amount of hot air can be prevented from being gathered above the wall-mounted air conditioner indoor unit 100, the temperature of the heat exchanger can be effectively reduced by preventing the hot air from rising due to the fact that the hot air enters the heat exchanger through the air inlet, and the hot air can be promoted to circulate fully in the indoor environment, so that the temperature distribution of the indoor environment is uniform.
In some specific embodiments, for controlling the opening degree of the expansion valve to increase, controlling the rotation speed of the indoor fan to increase, and adjusting the posture of the transverse guide plate 112, so as to enable the wall-mounted air conditioner indoor unit 100 to realize three measures of downward air blowing, any one of the measures can be adopted alone to promote the temperature distribution to be uniform and reduce the temperature of the heat exchanger, or any two or three of the measures can also be adopted to jointly promote the temperature distribution to be uniform and reduce the temperature of the heat exchanger.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
