Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In view of the fact that the prior art can only find the problem of poor heat dissipation of the outdoor unit installation environment through multiple inspections when a user finds that the air conditioner has poor cooling and heating effects, the invention innovatively provides an outdoor unit control method and device of an air conditioner and the air conditioner, so as to overcome one or more problems in the prior art.
As shown in fig. 1 and 2, one or more embodiments of the present invention can provide a method for controlling an outdoor unit of an air conditioner, which may include, but is not limited to, at least one of the following steps.
First, a first temperature T1 of an environment in which an outdoor unit of an air conditioner in a standby state is located is acquired. The invention can accurately judge whether the outdoor unit is in standby or not through the following modes: reading the total energy demand of the outdoor unit, indicating that the outdoor unit is in a standby state and in a waiting state under the condition that the total energy demand (the cooling or heating demand of the indoor unit on the outdoor unit) is zero, and indicating that the outdoor unit is working and not in the standby state if the total energy demand is not zero. In order to enable the first temperature T1 to more accurately and truly show the ambient temperature of the outdoor unit, the outdoor unit fan is controlled to start before the first temperature T1 is collected, and the first temperature T1 of the environment at the moment is collected after the fan works for a second preset time period T2; the mode can effectively avoid the influence of external conditions such as solar radiation on the environment temperature of the outdoor unit, and the first temperature T1 of the environment where the outdoor unit is located can be obtained more reliably and accurately by blowing air through the fan. In addition, the invention can collect the temperature of the environment where the outdoor unit is located after the detection of the total energy of the outdoor unit needs to be zero and the detection lasts for the preset time, thereby further ensuring the accuracy of temperature collection of the environment where the outdoor unit equipment is located.
When the method is implemented, the debugging mode can be set on the air conditioning equipment independently. The user can select or perform other operations through a remote controller or buttons or a combination of buttons on the equipment to enter a debugging mode, and then automatically select a cooling mode or a heating mode according to a specific value of the first temperature T1.
Secondly, the outdoor unit is controlled to operate for a first preset time period T1, and then a second temperature T2 of the current environment of the outdoor unit is obtained. The invention can control the working mode of the outdoor unit according to the first temperature T1, and concretely can control the outdoor unit to operate in a cooling mode according to the first temperature T1 being in a second set range; or controlling the outdoor unit to operate in the heating mode according to the first temperature T1 being within the third setting range. It should be understood that the second temperature T2 obtained in different operation modes of the outdoor unit is different.
In a refrigeration mode: specifically, the outdoor unit can be controlled to operate in the cooling mode according to the first temperature T1 being greater than or equal to the second set value S2 (i.e., within the second set range).
For example, the second set value S2 is 17 degrees celsius, and the outdoor unit is controlled to operate in the cooling mode according to some embodiments of the present invention under the condition that the detected first temperature T1 is 30 degrees celsius > 17 degrees celsius.
In the heating mode: specifically, the outdoor unit can be controlled to operate in the heating mode according to the first temperature T1 being less than or equal to the fourth set value S4 (i.e., within the third set range).
For example, the fourth set value S4 is 16 degrees celsius, and the outdoor unit is controlled to operate in the heating mode according to some embodiments of the present invention under the condition that the detected first temperature T1 is 9 degrees celsius < 16 degrees celsius.
It should be understood that the preset time period for controlling the operation of the outdoor unit in the cooling mode and the heating mode may be different or the same. For example, the first preset time period t1 is 40 minutes in the cooling mode, and the first preset time period t1 is 39 minutes in the heating mode.
Thirdly, the real-time environment temperature T3 from the cloud is read according to the temperature difference range between the second temperature T2 and the first temperature T1, and specifically, the real-time environment temperature T3 from the cloud can be read according to the condition that the temperature difference is outside the first set range, that is, the real-time environment temperature T3 from the cloud is read when the temperature difference between the second temperature T2 and the first temperature T1 is not within the first set range. The real-time ambient temperature T3 from the cloud may be the weather temperature of the location where the air conditioner outdoor unit is located, which is collected in real time, for example, obtained by obtaining weather information provided by a weather center, or may be collected separately.
In a refrigeration mode: the temperature difference between the second temperature T2 and the first temperature T1 is calculated, and the real-time ambient temperature T3 from the cloud can be read according to the temperature difference being 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, and the temperature difference between the second temperature T2 and the first temperature T1 is T2-T1-38-30-8 > 2, it indicates that the temperature difference is greater than the first set value S1, and the real-time ambient temperature T3 from the cloud 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 ambient temperature T3 from the cloud can be read according to the temperature difference being greater than the third set value S3 (i.e., outside the first set range). For example, the second temperature T2 is 3 degrees celsius, the first temperature T1 is 9 degrees celsius, and the third setting S3 is 3 degrees celsius, if the temperature difference between the first temperature T1 and the second temperature T2 is T1-T2-9-3-6 > 3, it indicates that the temperature difference is greater than the third setting S3, and the real-time ambient temperature T3 from the cloud is read.
Finally, the operation of the outdoor unit can be controlled according to the temperature difference between the real-time environment temperature T3 from the cloud and the second temperature T2, and the outdoor unit can be shut down temporarily or shut down after running for a preset time or control strategies such as increasing the fan rotating speed of the outdoor unit or reducing the working frequency of a compressor and the like can be realized according to the condition that the temperature difference between the real-time environment temperature T3 from the cloud and the second temperature T2 is greater than a preset value, so that the outdoor unit is prevented from being damaged due to poor heat dissipation of the installation environment as far as possible, and the outdoor unit of the air conditioner is protected, the service life.
In a refrigeration mode: and calculating the temperature difference between the second temperature T2 and the real-time environment temperature T3 from the cloud, and controlling the operation of the outdoor unit under the condition that the temperature difference is greater than a preset value R2 under the refrigeration working condition so as to reduce the possibility that the outdoor unit is damaged due to the poor installation environment of the outdoor unit. For example, the second temperature T2 is 38 degrees celsius, the real-time environment temperature T3 from the cloud is 31 degrees celsius, and the preset value R2 in the cooling mode is 3 degrees celsius, and if the temperature difference between the second temperature T2 and the real-time environment temperature T3 from the cloud is T2-T3-38-31-7 > 3, it can be said that the current temperature difference is greater than the preset value R2 in the cooling mode, and it is further determined that the heat dissipation of the outdoor unit installation environment is poor.
In the heating mode: and calculating the temperature difference between the real-time environment temperature T3 from the cloud and the second temperature T2, and controlling the operation of the outdoor unit under the condition that the temperature difference is greater than the preset value R1 under the heating working condition so as to reduce the possibility that the outdoor unit is damaged due to poor installation environment. For example, the second temperature T2 is 3 degrees celsius, the real-time environment temperature T3 from the cloud is 10 degrees celsius, and the preset value R1 in the heating mode is 2 degrees celsius, and if the temperature difference between the real-time environment temperature T3 from the cloud and the second temperature T2 is T3-T2-10-3-7 > 2, it can be said that the current temperature difference is greater than the preset value R1 in the heating mode, and it is further determined that the outdoor unit installation environment is poor in heat dissipation.
It should be understood that although the present invention exemplarily shows some specific parameter setting values, such as the first setting value, the second setting value, the third setting value, the fourth setting value, the first temperature, the second temperature, the real-time environment temperature from the cloud, etc., the present invention can be adjusted or reset according to the actual working condition and the equipment, so as to achieve the purpose of the present invention, that is, the parameter values listed in the present invention should not be construed as limiting the scope of the present invention.
The outdoor unit installation environment heat dissipation system can inform users or related workers of the outdoor unit installation environment heat dissipation situation in time. Specifically, the installation environment heat dissipation condition prompt information of the outdoor unit can be sent to the terminal according to the temperature difference between the real-time environment temperature T3 from the cloud and the second temperature T2. The installation environment heat dissipation condition prompt message in some embodiments of the present invention includes, but is not limited to, "poor heat dissipation of outdoor unit installation environment", "good heat dissipation of outdoor unit installation environment", and the like, and the form of the prompt message includes, but is not limited to, a prompt code, 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 debugging personnel terminal. The outdoor unit installation environment heat dissipation condition prompt information can be sent to the user terminal and/or the debugging personnel terminal through the cloud end, or the outdoor unit installation environment heat dissipation condition prompt information can be directly sent to the user terminal and the debugging personnel terminal through the intelligent air conditioning equipment. After receiving the prompt message, the debugging personnel can remind the debugging personnel of paying attention, the debugging personnel can reinstall the air conditioner outdoor unit, for example, the installation position or the installation mode of the outdoor unit can be adjusted, and the debugging can be realized by executing the method again after reinstalling until the requirement that the heat dissipation of the installation environment of the air conditioner outdoor unit is good is met. For the air conditioner user using the invention, the user can inform the relevant personnel to maintain the air conditioner outdoor unit as soon as possible after receiving the prompt message, thus the invention fully meets the requirement that the air conditioner user obtains the installation environment condition of the air conditioner outdoor unit in advance, can effectively improve the satisfaction degree of the air conditioner user, and the experience of the air conditioner user is very good.

The first temperature T1 obtaining module may be configured to obtain a first temperature T1 of an environment in which the outdoor unit is in a standby state. The first temperature T1 obtaining module can be specifically configured to read a total energy requirement of the outdoor unit, and to obtain a first temperature T1 of an environment in which the outdoor unit of the air conditioner is located according to a condition that the total energy requirement is zero and that the outdoor unit of the air conditioner is in a standby state. More specifically, the first temperature T1 obtaining module can be used to control the start of a fan of the outdoor unit and control the fan to operate for a second preset time period T2, and then collect the first temperature T1 of the environment where the outdoor unit is located.
The first device control module may be configured to control the outdoor unit to operate for a first preset time period t1, so as to obtain an installation environment temperature of the outdoor unit after the outdoor unit operates for a period of time.
The second temperature T2 obtaining module may be configured to obtain a second temperature T2 of the current environment of the outdoor unit according to the first preset time period T1 during which the outdoor unit operates. The second temperature T2 obtaining module can specifically control the outdoor unit to operate in a cooling mode or a heating mode according to the range of the first temperature T1: for controlling the outdoor unit to operate in the cooling mode based on the first temperature T1 being within a second set range, for example, the first temperature T1 being greater than or equal to a second set value S2, and operating for a first preset time period T1; or for controlling the outdoor unit to operate in the heating mode based on the first temperature T1 being within a third set range, for example, the first temperature T1 being less than or equal to the fourth set value S4; and operates for a first preset time period t 1. It can be understood that the above operation time periods of the outdoor unit of the air conditioner in the cooling mode and the cooling mode may be different or the same.
The cloud temperature reading module may be configured to read the real-time ambient temperature T3 from the cloud according to a temperature difference range between the second temperature T2 and the first temperature T1. The cloud temperature reading module is specifically configured to calculate a temperature difference between the second temperature T2 and the first temperature T1, and read the real-time ambient temperature T3 from the cloud in the cooling mode according to a condition that the temperature difference is greater than a first set value S1, or read the real-time ambient temperature T3 from the cloud in the heating mode according to a condition that the temperature difference is greater than a third set value S3. The real-time ambient temperature T3 from the cloud may be, for example, the weather temperature of the location where the air conditioner outdoor unit is located, which is collected in real time.
The second device control module may be configured to control operation of the outdoor unit according to a temperature difference between the real-time ambient temperature T3 from the cloud and the second temperature T2. If the temperature difference between the real-time environment temperature T3 from the cloud and the second temperature T2 can represent that the outdoor unit is poor in heat dissipation in the installation environment, the second device control module can be used for controlling the outdoor unit to stop or increasing the rotating speed of the fan or stopping after running for a short time, so that the outdoor unit is effectively prevented from being damaged due to poor heat dissipation in the installation environment. The invention can also enable a user or debugging personnel to know the condition of poor heat dissipation of the installation environment before the outdoor unit is damaged, and the specific implementation process is as follows.
The heat dissipation condition prompt module can be used for sending the installation environment heat dissipation condition prompt information of the outdoor unit to the terminal of an installation and debugging worker or the handheld terminal of the user according to the temperature difference between the real-time environment temperature T3 from the cloud and the second temperature T2. The prompt message of the heat dissipation condition of the installation environment can be sent by a cloud server or can be sent by an intelligent air conditioner. The user who receives the prompt message can inform the air conditioner maintenance personnel of door-to-door debugging and maintenance according to actual conditions, and the debugging personnel who receives the prompt message can reinstall the air conditioner outdoor unit, so that the heat dissipation of the outdoor unit installation environment is good.
The invention innovatively bases on the ambient temperature of the outdoor unit in a standby state, the ambient temperature of the outdoor unit after operation for a period of time and the real-time ambient temperature from a cloud end as judgment bases, thereby intelligently and automatically judging whether the heat dissipation condition of the outdoor unit installation environment is good or not, and informing users or related workers of the judgment result in time, better solving the problems of outdoor unit damage, poor cooling and heating effects and the like caused by poor heat dissipation of the air conditioner outdoor unit installation environment in the prior art, and obviously improving the satisfaction degree and experience of the users to the air conditioning equipment.
