The present disclosure relates to the field of intelligent control technologies for air conditioners. More specifically, the present disclosure can provide a method and apparatus for controlling an outdoor unit of an air conditioner, and an air conditioner.
An outdoor unit of an air conditioner may often be mounted in a semi-closed space or even a closed space. This may cause poor heat dissipation of the outdoor unit of the air conditioner, impacting the cooling and heating performance of an air conditioning system, and may even damage the outdoor unit. Troubleshooting may only be initiated when the cooling and heating performance of the air conditioner is found to be seriously affected. A maintenance person may have to go through several checks before discovering that the cause is poor heat dissipation in an installation environment of the outdoor unit. The outdoor unit of the air conditioner may malfunction due to the poor heat dissipation.
The present disclosure provides a method for controlling an outdoor unit of an air conditioner that may better protect the outdoor unit of the air conditioner, help ensure the normal operation of the outdoor unit, and may allow an early detection of poor heat dissipation in the installation environment. The method includes obtaining a first temperature of an environment in which the outdoor unit in a standby state is located; controlling the outdoor unit to operate for a first predetermined duration prior to obtaining a second temperature of the environment in which the outdoor unit is located. The method includes obtaining a real-time temperature of the environment from a cloud server based on a range of a temperature difference between the second temperature and the first temperature; and controlling an operation of the outdoor unit based on a temperature difference between the real-time temperature of the environment from the cloud server and the second temperature.
Some embodiments of the present disclosure may allow poor heat dissipation in an installation environment for the outdoor unit to be detected in advance based on a temperature of an environment in which the outdoor unit, in the standby state, is located, a temperature of the environment subsequent to a period of time of operation of the outdoor unit, and a real-time temperature of the environment, obtained from a cloud server, and a subsequent operation of the outdoor unit may be controlled in a timely manner to protect the outdoor unit. An entire determination process of the present disclosure may no longer involve manual intervention, and thus some embodiments of present disclosure may provide a high degree of automation.
The control method further includes: transmitting information about heat dissipation in the installation environment to a terminal based on the temperature difference between the real-time temperature of the environment obtained from the cloud server and the second temperature. The terminal is a user terminal and/or a commissioning personnel's terminal.
A user or any relevant personnel may be promptly and quickly informed in advance about heat dissipation of the installation environment for the outdoor unit. Embodiments of the present disclosure may save a time spent on investigating the cause when cooling and heating performance of the air conditioner is found to be seriously affected, and may also effectively avoid damages to the outdoor unit caused by poor heat dissipation in the installation environment, which may provide good protection to the outdoor unit, prolonging a service life of the outdoor unit of the air conditioner, and may offer good user experience.
Further, obtaining the first temperature of the environment in which the outdoor unit in the standby state is located includes: reading a total energy demand of the outdoor unit; determining, in accordance with a determination that the total energy demand is zero, that the outdoor unit is in the standby state; and obtaining the first temperature of the environment in which the outdoor unit is located.
In some embodiments, the outdoor unit in the standby state can be further accurately determined to more accurately obtain a real temperature of the environment in which the outdoor unit is located, avoiding misinformation of heat dissipation due to a detection error of the first temperature. Thus, in the present disclosure, high reliability may be provided.
Further, obtaining the first temperature of the environment in which the outdoor unit is located includes: controlling a fan of the outdoor unit to start; controlling the fan to operate for a second predetermined duration; and collecting the first temperature of the environment in which the outdoor unit is located.
In some embodiments, an air flow speed of the environment in which the outdoor unit is located can be accelerated by means of turning on the fan, to prevent a temperature detection result of the environment in which the outdoor unit is located from being affected by external factors such as solar radiation. A more accurate and reliable collection result of the first temperature may be provided.
Further, controlling the outdoor unit to operate for the first predetermined duration includes: controlling, in accordance with a determination that the first temperature is within a second set range, the outdoor unit to operate in a cooling mode for the first predetermined duration. The reading the real-time temperature of the environment from the cloud server based on the range of the temperature difference between the second temperature and the first temperature includes: calculating the temperature difference between the second temperature and the first temperature, and reading the real-time temperature of the environment from the cloud server in accordance with a determination that the temperature difference is greater than a first set value.
Further, controlling, in accordance with a determination that the first temperature is within the second set range, the outdoor unit to operate in the cooling mode includes: controlling, in accordance with a determination that the first temperature is greater than a second set value, the outdoor unit to operate in the cooling mode.
In the present disclosure, the above improved technical solution can be applied in a poor heat dissipation detection for the installation environment for the outdoor unit in summer. By controlling the outdoor unit to operate in the cooling mode, the environment temperature of the outdoor unit subsequent to a period of time of operation of the outdoor unit is determined and compared with the real-time temperature of the environment from the cloud server, to obtain an accurate determination result.
Further, controlling the outdoor unit to operate for the first predetermined duration includes: controlling, in accordance with a determination that the first temperature is within a third set range, the outdoor unit to operate in a heating mode for the first predetermined duration. The reading the real-time temperature of the environment from the cloud server based on the range of the temperature difference between the second temperature and the first temperature includes: calculating the temperature difference between the first temperature and the second temperature, and reading the real-time temperature of the environment from the cloud server in accordance with a determination that the temperature difference is greater than a third set value.
Further, controlling, in accordance with a determination that the first temperature is within the third set range, the outdoor unit to operate in the heating mode includes: controlling, in accordance with a determination that the first temperature is smaller than a fourth set value, an outdoor unit to operate in the heating mode.
In the present disclosure, the above improved technical solution can be applied in a poor heat dissipation detection for the installation environment for the outdoor unit in winter. By controlling the outdoor unit to operate in the heating mode, the environment temperature of the outdoor unit subsequent to a period of time of operation of the outdoor unit is determined and compared with the real-time temperature of the environment from the cloud server, to obtain an accurate determination result.
To achieve the above technical objective, the present disclosure can further provide an apparatus for controlling an outdoor unit of an air conditioner. The apparatus can include, but is not limited to, a first temperature obtaining module, a first device control module, a second temperature obtaining module, a cloud-based temperature reading module, and a second device control module.
The first temperature obtaining module is configured to obtain a first temperature of an environment in which the outdoor unit in a standby state is located.
The first device control module is configured to control the outdoor unit to operate for a first predetermined duration.
The second temperature obtaining module is configured to obtain, based on the outdoor unit having operated for the first predetermined duration, a second temperature of the environment in which the outdoor unit is located.

In the present disclosure, the above technical solutions, innovatively, can detect in advance the poor heat dissipation in the installation environment for the outdoor unit based on the environment temperature of the outdoor unit in the standby state, the environment temperature of the outdoor unit subsequent to a period of time of operation of the outdoor unit, and the real-time temperature of the environment from the cloud server, and can control the subsequent operation method of the outdoor unit in a timely manner to protect the outdoor unit. An entire determination process of the present disclosure no longer requires manual intervention, and thus the technical solutions in the present disclosure have outstanding advantages such as a high degree of automation and intellectualization.
To realize the above technical objective, the present disclosure can further provide an air conditioner. The air conditioner can include, but is not limited to, the apparatus for controlling the outdoor unit according to any embodiment of the present disclosure.
Some embodiments of the present disclosure may realize an intelligent, automatic, and accurate determination of poor heat dissipation in the installation environment of the outdoor unit, without human intervention. In some embodiments, the environment temperature of the outdoor unit in the standby state and the real-time temperature of the environment from the cloud server are used as the basis for the determination, which may improve an accuracy and reliability of the determination of the heat dissipation of the installation environment for the outdoor unit. Therefore, in some embodiments of the present disclosure, poor heat dissipation in the installation environment for the outdoor unit may be detected in advance, and the user or the relevant person of the problem may be notified in a timely manner to eliminate a faulty condition before damages are caused to the outdoor unit of the air conditioner.
Implementations of the objectives, functional features, and advantages of the present disclosure will be further described in connection with the embodiments and with reference to the accompanying drawings.
Technical solutions according to embodiments of the present disclosure will be described clearly and completely below in combination with accompanying drawings of the embodiments of the present disclosure. The embodiments described below are only a part of the embodiments of the present disclosure, rather than all embodiments of the present disclosure. On a basis of the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative labor shall fall within the protection scope of the present disclosure.
Instead of the user discovering that the air conditioner has poor cooling and heating performance due to poor heat dissipation in an installation environment through a number of inspections, the present disclosure provide a method and apparatus for controlling an outdoor unit of an air conditioner, and an air conditioner.
As illustrated in
A first temperature T1 of an environment in which an outdoor unit of an air conditioner in a standby state is located is obtained. In the present disclosure, whether the outdoor unit is on standby or not can be accurately determined through reading a total energy demand of the outdoor unit. When the total energy demand (a demand quantity of cooling or heating issued by an indoor unit to the outdoor unit) is zero, the outdoor unit is on standby or in a waiting state. When the total energy demand is non-zero, the outdoor unit is in operation or not on standby. In the present disclosure, to make the first temperature T1 show an environment temperature of the outdoor unit more accurately and more realistically, a fan of the outdoor unit is controlled to start prior to a collection of the first temperature T1, and then the first temperature T1 of the environment is collected subsequent to an operation of the fan for a second predetermined duration t2. Such a method can effectively avoid the influence of external factors, such as solar radiation, on the environment temperature of the outdoor unit. The first temperature T1 of the environment in which the outdoor unit is located can be more reliably and accurately obtained in a manner of blowing air by the fan. In addition, in the present disclosure, an operation of collecting the temperature of the environment in which the outdoor unit is located may be performed, in response to detecting that the total energy demand of the outdoor unit is zero and that the total energy demand stays zero for a predetermined duration, further ensuring an accuracy of collecting the temperature of the environment in which the outdoor unit is located.
In a specific implementation of the present disclosure, a commissioning mode may be set separately for an air-conditioning device. The commissioning mode is activated through performing a selection or other operations by means of a remote control, a button on the device, or a combination thereof. A cooling mode or a heating mode is then automatically selected based on a specific value of the first temperature T1.
The outdoor unit is controlled to operate for the first predetermined duration T1, and then a second temperature T2 of the environment in which the outdoor unit is located is obtained. In the present disclosure, an operation mode of the outdoor unit may be controlled based on the first temperature T1. In some embodiments, controlling the operation mode of the outdoor unit based on the first temperature T1 may include: controlling, in accordance with a determination that the first temperature T1 is within a second set range, the outdoor unit to operate in a cooling mode; or controlling, in accordance with a determination that the first temperature T1 is within a third set range, the outdoor unit to operate in a heating mode. It should be understood that the second temperatures T2 obtained tend to be different in different operation modes of the outdoor unit.
In the cooling mode: in some embodiments, the outdoor unit may be controlled, in accordance with a determination that the first temperature T1 is greater than or equal to the second set value S2 (i.e., within the second set range), to operate in the cooling mode.
For example, the second set value S2 is 17 degrees Celsius. In some embodiments of the present disclosure, the outdoor unit is controlled to operate in the cooling mode, in response to detecting that the first temperature T1 is 30 degrees Celsius, which is greater than 17 degrees Celsius.
In the heating mode: in some embodiments, the outdoor unit may be controlled, in accordance with a determination that the first temperature T1 is smaller than or equal to a fourth set value S4 (i.e., within the third set range), to operate in the heating mode.
For example, the fourth set value S4 is 16 degrees Celsius. In some embodiments of the present disclosure, the outdoor unit is controlled to operate in the heating mode, in response to detecting that the first temperature T1 is 9 degrees Celsius, which is smaller than 16 degrees Celsius.
It should be understood that the predetermined durations for controlling the outdoor unit to operate in the cooling mode and the heating mode may be different or the same. For example, the first predetermined duration t1 in the cooling mode is 40 minutes, and the first predetermined duration t1 in the heating mode is 39 minutes.
A real-time temperature of the environment T3 from a cloud server is read based on a range of a temperature difference between the second temperature T2 and the first temperature T1. In some embodiments, the real-time temperature of the environment T3 from the cloud server may be read based on a condition that the temperature difference is outside the first set range. That is, the real-time temperature of the environment T3 from the cloud server is read under a condition that the temperature difference between the second temperature T2 and the first temperature T1 is not in the first set range. The real-time temperature of the environment T3 from the cloud server may be a temperature collected in real time for a location of the outdoor unit of the air conditioner. For example, the real-time temperature of the environment T3 from the cloud server may be obtained through obtaining weather information provided by a weather center, or a real-time temperature may be collected separately.
In the cooling mode: the temperature difference between the second temperature T2 and the first temperature T1 is calculated, and the real-time temperature of the environment T3 from the cloud server may be read in accordance with a determination that the temperature difference is greater than the first set value S1 (i.e., outside the first set range). For example, if the second temperature T2 is 38 degrees Celsius, the first temperature T1 is 30 degrees Celsius, and the first set value S1 is 2 degrees Celsius, the temperature difference between the second temperature T2 and the first temperature T1 is equal to T2−T1=38−30=8>2, which indicates that the temperature difference is greater than the first set value S1. Thus, the real-time temperature of the environment T3 from the cloud server is read.
In the heating mode: the temperature difference between the first temperature T1 and the second temperature T2 is calculated, and the real-time temperature of the environment T3 from the cloud server is read in accordance with a determination that the temperature difference is greater than a third set value S3 (i.e., outside the first set range). For example, if the second temperature T2 is 3 degrees Celsius, the first temperature T1 is 9 degrees Celsius, and the third set value S3 is 3 degrees Celsius, the temperature difference between the first temperature T1 and the second temperature T2 is equal to T1−T2=9−3=6>3, which indicates that the temperature difference is greater than the third set value S3. Thus, the real-time temperature of the environment T3 from the cloud server is read.
In the present disclosure, an operation of the outdoor unit can be controlled based on a temperature difference between the real-time temperature of the environment T3 from the cloud server and the second temperature T2. On a basis of a condition that the temperature difference between the real-time temperature of the environment T3 from the cloud server and the second temperature T2 is greater than a predetermined value, the outdoor unit may be shut down temporarily, or the outdoor unit may be shut down after operating for a predetermined duration, or a rotational speed of the fan of the outdoor unit may be increased, or an operation frequency of a compressor may be reduced, or other control strategies may be adopted, to avoid as much as possible damages to the outdoor unit that may be caused by poor heat dissipation in the installation environment, serving purposes such as protecting the outdoor unit of the air conditioner and prolonging the life of the outdoor unit.
In the cooling mode: the temperature difference between the second temperature T2 and the real-time temperature of the environment T3 from the cloud server is calculated. The operation of the outdoor unit is controlled when the temperature difference is greater than a predetermined value R2 in a cooling operating condition, to reduce a possibility of damages to the outdoor unit of the air conditioner caused by the poor installation environment for the outdoor unit. For example, if the second temperature T2 is 38 degrees Celsius, the real-time temperature of the environment T3 from the cloud server is 31 degrees Celsius, and the predetermined value R2 in the cooling mode is 3 degrees Celsius, the temperature difference between the second temperature T2 and the real-time temperature of the environment T3 from the cloud server is equal to T2-T3=38−31=7>3, which indicates that a current temperature difference is greater than the predetermined value R2 in the cooling mode. Thus, it is further determined that the installation environment for the outdoor unit is in a poor heat dissipation condition.
In the heating mode: the temperature difference between the real-time temperature of the environment T3 from the cloud server and the second temperature T2 is calculated. The operation of the outdoor unit is controlled when the temperature difference is greater than a predetermined value R1 in a heating operating condition, to reduce a possibility of damages to the outdoor unit of the air conditioner caused by the poor installation environment for the outdoor unit. For example, if the second temperature T2 is 3 degrees Celsius, the real-time temperature of the environment T3 from the cloud server is 10 degrees Celsius, and the predetermined value R1 in the heating mode is 2 degrees Celsius, the temperature difference between the real-time temperature of the environment T3 from the cloud server and the second temperature T2 is equal to T3−T2=10−3=7>2, which indicates that the current temperature difference is greater than the predetermined value R1 in the heating mode. Thus, it is further determined that the installation environment for the outdoor unit is in a poor heat dissipation condition.
It should be understood that although some specific example parameter setting values, such as a first set value, a second set value, a third set value, a fourth set value, the first temperature, the second temperature, and the real-time temperature of the environment from the cloud server are provided in the present disclosure, theses example parameter setting values can be adjusted or reset in the present disclosure based on an actual operating condition and an actual device, as long as objectives of the present disclosure can be realized. That is, parameter values listed in the present disclosure shall not be construed as limitations on the protection scope of the present disclosure.
With the present disclosure, the user or a relevant person can be timely informed of a heat dissipation condition in the installation environment for the outdoor unit. In some embodiments, installation environment heat dissipation prompt information of the outdoor unit may be transmitted to a terminal based on the temperature difference between the real-time temperature of the environment T3 from the cloud server and the second temperature T2. In some embodiments of the present disclosure, the installation environment heat dissipation prompt information includes, but is not limited to, “poor heat dissipation in the installation environment for the outdoor unit”, “good heat dissipation of the installation environment for the outdoor unit”, or the like. Forms of the prompt information include, but are not limited to, prompt codes, a short message, a picture, a prompt sound, a vibration, or a combination of at least two of these forms. The terminal is a user terminal and/or a commissioning personnel's terminal. In the present disclosure, the installation environment heat dissipation prompt information of the outdoor unit may be transmitted to the user terminal and/or the commissioning personnel's terminal via the cloud server, or the installation environment heat dissipation prompt information may be transmitted to the user terminal and/or the commissioning personnel's terminal directly by an intelligent air-conditioning device. When the commissioning personnel receives the prompt information, a purpose of reminding the commissioning personnel to pay attention to the outdoor unit can be realized. The commissioning personnel may re-mount the outdoor unit of the air conditioner. For example, a mounting position, a mounting method, or the like of the outdoor unit may be adjusted. The method in the present disclosure may be re-executed after the remounting to realize commissioning, until the installation environment for the outdoor unit of the air conditioner can provide good heat dissipation. For a user using an air conditioner in which the present disclosure is applied, the user can notify the relevant person to carry out maintenance of the outdoor unit of the air conditioner as soon as possible after receiving the prompt information. Thus, in the present disclosure, a demand for obtaining an installation environment condition of the outdoor unit of the air conditioner in advance may be satisfied for the user using the air conditioner, which may improve user satisfaction of the air conditioner, and may provide the user using the air conditioner with good use experience.
In the cooling mode: the temperature difference between the second temperature T2 and the real-time temperature of the environment T3 from the cloud server is calculated. The installation environment heat dissipation prompt information is transmitted to a terminal of the user or the relevant person when the temperature difference is greater than the predetermined value R2 under the cooling operating condition.
In the heating mode, the temperature difference between the real-time temperature of the environment T3 from the cloud server and the second temperature T2 is calculated. The installation environment heat dissipation prompt information is transmitted to the terminal of the user or the relevant person when the temperature difference is greater than the predetermined value R1 under the heating operating condition.
With the present disclosure, a cloud-based determination of the heat dissipation condition in the installation environment for the outdoor unit of the air conditioner can be realized. In some embodiments, no manual intervention is involved in the whole intelligent determination process, which may improve use experience and satisfaction of the user.

It should be understood that operation durations of the outdoor unit of the air conditioner in the cooling mode and the heating mode may be different or the same.

The real-time temperature of the environment T3 from the cloud server may be, for example, the weather temperature collected in real time for the location of the outdoor unit of the air conditioner.
The second device control module can be configured to control the operation of the outdoor unit based on the temperature difference between the real-time temperature of the environment T3 from the cloud server and the second temperature T2. The second device control module can be configured to control the outdoor unit to shut down, or increase the rotational speed of the fan, or control the outdoor unit to shut down subsequent to an operation of the outdoor unit for a short period of time, etc., when the temperature difference between the real-time temperature of the environment T3 from the cloud server and the second temperature T2 characterizes poor heat dissipation in the installation environment for the outdoor unit, to effectively avoid occurrences of accidents such as damages to the outdoor unit that may be caused by the poor heat dissipation in the installation environment. In addition, in the present disclosure, the user or the commissioning personnel can be informed of the poor heat dissipation in the installation environment before the outdoor unit is damaged. A specific implementation process is as follows.
The heat dissipation prompt module can be configured to transmit the installation environment heat dissipation prompt information of the outdoor unit to a terminal of the commissioning personnel or a handheld terminal of the user based on the temperature difference between the real-time temperature of the environment T3 from the cloud server and the second temperature T2. The installation environment heat dissipation prompt information may be transmitted by a cloud server or by an intelligent air conditioner. The user who receives the prompt information can notify, based on an actual situation, an air conditioner maintenance person to come to the door for commissioning and maintenance. The commissioning personnel who receives the prompt information can re-mount the outdoor unit of the air conditioner to realize good heat dissipation in the installation environment for the outdoor unit.
Innovatively, with the environment temperature of the outdoor unit in the standby state, the environment temperature of the outdoor unit subsequent to the operation of the outdoor unit for a period of time, and the real-time temperature of the environment from the cloud server as the basis for determination, in the present disclosure, whether the installation environment for the outdoor unit is in a good heat dissipation condition or not can be determined intelligently and automatically, and the determination result can be notified in time to the user or relevant person, and may reduce or prevent damages to the outdoor unit or the poor cooling and heating performance that are caused by the poor heat dissipation in the installation environment for the outdoor unit of the air conditioner, and may improve satisfaction and use experience of the user with the air conditioning device.
