The refrigerant is an important component for ensuring the normal operation of the air conditioner. Once the air conditioner has a refrigerant loss, the use experience of a user is influenced, and the air conditioner can be damaged.
Currently, only when the refrigerant of the air conditioner is very seriously lost and the user experience is seriously influenced, the user can pay attention to the problem of the lack of the refrigerant of the air conditioner. In fact, the leakage of refrigerant is a relatively long process, and generally, during the leakage of refrigerant, the user cannot be clearly distinguished. That is, if the degree of shortage of the refrigerant is not particularly serious, the user cannot perceive an abnormality from the operation state of the air conditioner. Even if the degree of refrigerant shortage is not severe, there is still some damage to the life of the compressor and the refrigeration system. And, the user can not experience better refrigeration effect at this moment, cause the bad influence to user experience.
Disclosure of Invention
In view of the above, the present invention is directed to a method for controlling an air conditioner to solve the problem that a user cannot know that the air conditioner is lack of refrigerant in time.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
an air conditioner control method applied to the air conditioner, the method comprising: acquiring the concentration information of a refrigerant in a box body of the air conditioner in an operating state according to a preset time interval; comparing a first concentration threshold value and a second concentration threshold value preset by the acquired concentration information, wherein the first concentration threshold value is smaller than the second concentration threshold value; when the concentration information is larger than the second concentration threshold value, controlling the air conditioner to stop working and giving an alarm; and when the concentration information is less than or equal to the second concentration threshold and greater than or equal to the first concentration threshold, controlling a compressor of the air conditioner to reduce the frequency and carrying out early warning.
Further, the method further comprises: acquiring temperature information of a compressor cylinder body of the air conditioner according to a preset time interval; and when the concentration information is less than or equal to the second concentration threshold value and greater than or equal to the first concentration threshold value and the temperature information of the compressor cylinder body exceeds a preset temperature threshold value, controlling the air conditioner to stop working and giving an alarm.
Compared with the prior art, the air conditioner control method has the following advantages:
(1) according to the control method of the air conditioner, the refrigerant is firstly collected into the box body of the air conditioner after leaking from the refrigerating system of the air conditioner under the normal condition, and the concentration of the refrigerant in the box body is directly detected, so that whether the situation of lack of the refrigerant occurs or not can be judged in time. The whole detection process does not influence the normal operation of the air conditioner, and the coupling degree is low. The degree of the lack of the concentration of the current refrigerant can be effectively and quickly judged according to the refrigerant concentration interval divided by the first concentration threshold and the second concentration threshold and the concentration information of the refrigerant. Meanwhile, when the concentration information belongs to the range between the first concentration threshold and the second concentration threshold, namely when the refrigerant is not serious due to the fact that the refrigerant is lost in the air conditioner, the frequency of a compressor of the air conditioner is reduced and a user is reminded, the compressor is protected, and the user can be reminded under the condition that the use of the user is not influenced. The use experience of the customer is effectively improved.
(2) According to the air conditioner control method, the temperature information of the compressor cylinder body of the air conditioner is obtained, and the lack condition of the refrigerant in the air conditioner is judged by combining the temperature of the compressor cylinder body and the concentration information, so that the error judgment of the fact condition of the refrigerant in the air conditioner caused by inaccurate detected concentration information after the refrigerant is lost from the box body of the air conditioner to the outside is effectively overcome, and the accuracy of the air conditioner control method in judging the lack condition of the refrigerant in the air conditioner is improved.

Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. In addition, the temperature of the compressor cylinder mentioned in the embodiment of the present invention is information on the temperature of the compressor cylinder of the air conditioner 100. The missing proportion information mentioned in the embodiment refers to the ratio information between the amount of the refrigerant that normally works in the refrigeration system of the air conditioner 100 and the initial amount of the refrigerant in the refrigeration system.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
First embodiment
Referring to fig. 1, fig. 1 illustrates an air conditioner control method according to an embodiment of the present invention. The air conditioner control method is applied to an air conditioner 100 shown in fig. 2, and the air conditioner 100 comprises a refrigerant detection module 10, a control module 20 and an alarm module 30. As shown in fig. 1, the method comprises the steps of:
step S101 is to acquire the concentration information of the refrigerant in the cabinet of the air conditioner 100 in the operating state at preset time intervals.
In this embodiment, the air conditioner 100 further includes a refrigeration system. The refrigeration system may include a compressor, a condenser, an expansion valve, and an evaporator. The refrigerating system is arranged in the box body. A refrigerant detection module 10 is further arranged in the box body, and the refrigerant detection module 10 can be a refrigerant probe. The refrigerant detection module 10 obtains the concentration information of the refrigerant in the cabinet of the air conditioner 100 in the operating state at preset time intervals, for example, 5s collects the concentration information of the refrigerant in the cabinet of the air conditioner 100 once. It should be noted that the refrigerant may be a working substance (e.g., freon) that circulates through the refrigeration system continuously and changes its state to achieve refrigeration. The continuous circulation of the refrigerant in the refrigeration system may ensure the normal operation of the air conditioner 100, but the leakage of the refrigerant from the refrigeration system may be unavoidable due to the air conditioner 100 itself or due to time. The refrigerant leaking from the refrigerating system is first collected in the cabinet of the air conditioner 100 and exists in a gaseous state. Therefore, the concentration information of the refrigerant in the box body can be acquired by the refrigerant probe according to the preset time interval, so that the leakage condition of the refrigerant from the refrigerating system can be acquired quickly and timely. The refrigerant detection module 10 and the refrigeration system are not coupled, so that the normal operation of the refrigeration system is not influenced in the whole detection process.
And step S102, comparing the acquired concentration information with a preset first concentration threshold and a preset second concentration threshold.
In this embodiment, a first density threshold and a second density threshold may be preset, where the first density threshold is smaller than the second density threshold. Optionally, a corresponding concentration interval is generated according to the first concentration threshold and the second concentration threshold. Specifically, a first concentration interval is defined as a concentration less than a first concentration threshold; a second concentration interval which is greater than or equal to the first concentration threshold and less than or equal to the second concentration threshold; the concentration greater than the second concentration threshold value is a third concentration interval. And comparing the concentration interval to which the current concentration information belongs with a preset first concentration threshold and a preset second concentration threshold by judging the concentration interval to which the current concentration information belongs. As an embodiment, the first concentration threshold may be 50g/m 3; the second concentration threshold may be 100g/m 3.
And step S103, when the concentration information is greater than the second concentration threshold, controlling the air conditioner 100 to stop working and giving an alarm.
In this embodiment, when the concentration information detected by the refrigerant detection module 10 is greater than the second concentration threshold, that is, the concentration information belongs to the third concentration interval, it indicates that the lack of the refrigerant in the current refrigeration system is very serious, and the use experience of the user is already seriously affected, and meanwhile, the air conditioner 100 is seriously damaged by the continuous operation. Therefore, the air conditioner 100 is immediately controlled to stop operating at this time, and an alarm prompt tone is issued through the alarm module 30. Alternatively, the alarm module 30 may be a buzzer.
And step S104, when the concentration information is less than or equal to the second concentration threshold and greater than or equal to the first concentration threshold, controlling the compressor of the air conditioner 100 to reduce the frequency and perform early warning.
In this embodiment, when the concentration information detected by the refrigerant detection module 10 is less than or equal to the second concentration threshold and greater than or equal to the first concentration threshold, that is, the concentration information belongs to the second concentration interval, it indicates that the lack of the refrigerant in the current refrigeration system is not serious, and the user cannot sense the change of the refrigeration system through the self-sensing organ at this time although the user cannot obtain the best cooling or heating effect. But at this time, damage to the air conditioner 100 may still be present in the refrigeration system due to partial leakage of the refrigerant. Therefore, when the concentration information is less than or equal to the second concentration threshold and greater than or equal to the first concentration threshold, the operating frequency of the compressor of the air conditioner 100 is reduced, and the air conditioner 100 is protected. Meanwhile, the air speed of the indoor unit of the air conditioner 100 is reduced, so that the user can feel that the lack of the refrigerant occurs, and the user can pay more attention to whether the lack of the refrigerant occurs in the air conditioner 100. And sends out an early warning tone through the alarm module 30. Alternatively, the alarm module 30 may be a buzzer. It should be noted that the alarm prompt tone and the warning prompt tone may be different.
In this embodiment, when the concentration information detected by the refrigerant detection module 10 is less than the first concentration threshold, that is, the concentration information belongs to the first concentration interval, it may be considered that the refrigerant in the air conditioner 100 is sufficient currently, and the air conditioner 100 still operates normally.
In this embodiment, the air conditioner 100 further includes a GPS module 60 and a communication module 70, and the air conditioner 100 is connected to the maintenance server through the communication module 70. It should be noted that, the maintenance server stores therein maintenance site information in charge of each area, the maintenance site information includes information of communication terminals held by the maintenance site registration, and the maintenance server may perform data interaction with the communication terminals of the maintenance site according to the maintenance site information. The maintenance site information for each area stored in the maintenance server can be updated on trial.
As shown in fig. 3, each time after the alarm module 30 makes an alarm, the method further includes:
step S105, current position information is acquired.
In the present embodiment, the current location information of the air conditioner 100 is acquired through the GPS module 60 installed in the air conditioner 100.
And step S106, sending a maintenance request to a maintenance site corresponding to the region to which the maintenance server belongs according to the current position information.
In this embodiment, a maintenance request is generated according to the current position information, and the maintenance request is sent to a maintenance server. The maintenance server matches corresponding maintenance site information according to the current position information corresponding to the maintenance request, and specifically, the maintenance site information corresponding to the area of the current position information can be inquired. And then sending the maintenance request to a communication terminal corresponding to the maintenance site information.
In this embodiment, after the warning module 30 performs the warning each time, the air conditioner 100 may collect the temperature information of the compressor cylinder through the temperature sensor 40 disposed on the compressor cylinder. Acquiring the missing proportion information of the current refrigerant according to the concentration information, the temperature information of the compressor cylinder and the initial refrigerant amount; and displaying the missing proportion information so as to remind a user. As an embodiment, a correspondence model between the concentration information, the temperature information of the compressor cylinder, and the initial refrigerant amount and the remaining refrigerant in the refrigeration system may be established in advance through a large amount of test data and stored. After the alarm module 30 performs early warning, the air conditioner 100 obtains the remaining refrigerant amount in the refrigeration system by using the corresponding relation model according to the current concentration information, the temperature information of the compressor cylinder and the initial refrigerant amount, and obtains the missing proportion information according to the remaining refrigerant amount and the initial refrigerant amount. Finally, the display module 50 of the indoor unit of the air conditioner 100 is controlled to display.
Second embodiment

step S201 is to acquire the concentration information of the refrigerant in the cabinet of the air conditioner 100 in the operating state at preset time intervals.
Step S202, comparing the acquired concentration information with a preset first concentration threshold and a preset second concentration threshold.

In the present embodiment, the air conditioner 100 includes an outdoor unit. A compressor is arranged in the outdoor unit, and a temperature sensor 40 is arranged near a cylinder body of the compressor and used for acquiring temperature information of the cylinder body of the compressor. It should be noted that, when a refrigerant shortage occurs in the refrigeration system, the temperature of the compressor cylinder tends to rise until the compressor cylinder is burned out.
And step S204, when the concentration information is less than or equal to the second concentration threshold and greater than or equal to the first concentration threshold, and the temperature information of the compressor cylinder exceeds a preset temperature threshold, controlling the air conditioner 100 to stop working and giving an alarm.
In the present embodiment, the preset temperature threshold may be any value between 90 and 110 degrees. The condition of lack of the refrigerant in the refrigerating system is judged by combining the temperature information of the compressor cylinder body, so that the condition that the judgment is inaccurate due to the fact that the refrigerant in the box body is emitted to the outside under special conditions can be effectively eliminated.
And S205, when the concentration information is smaller than the first concentration threshold value and the temperature information of the compressor cylinder exceeds a preset temperature threshold value, controlling the air conditioner 100 to stop working and giving an alarm.
