An air conditioner serving as indoor environment temperature regulation equipment generally comprises the following four parts:
a refrigeration system: the air conditioner is a refrigeration cooling part, and a sealed refrigeration cycle is formed by a refrigeration compressor, a condenser, a capillary tube, an evaporator, an electromagnetic directional valve, a filter, a refrigerant and the like.
An air path system: the air conditioner is a part for promoting room air to accelerate heat exchange, and consists of a centrifugal fan, an axial flow fan and other equipment.
An electrical system: the air conditioner is a part for promoting safe operation of a compressor and a fan and controlling temperature in the air conditioner, and consists of a motor, a temperature controller, a relay, a capacitor, a heater and the like.
Box and panel: the air conditioner consists of frame, support seat and airflow guide part, and consists of casing, panel, louver, etc.
The refrigerant is used in the refrigerating and air-conditioning system to transfer heat energy and produce refrigerating effect. The refrigerant is an intermediate substance in the refrigeration process, and the refrigerant receives the cold energy of the refrigerant to cool the refrigerant and then cools other cooled substances, and the intermediate substance is called as the refrigerant. The refrigerant comprises gas refrigerant, liquid refrigerant and solid refrigerant, and the gas refrigerant mainly comprises air and the like; the liquid refrigerant includes water, saline water and the like; ice, dry ice, and the like are used as the solid refrigerant.
The refrigerant commonly used in air conditioning engineering is water and air. In daily life, refrigerators, freezers, and commercial refrigerators all use air as a refrigerant to transfer the cooling energy during the cooling process to food during the circulation cooling process, so that the food is frozen and stored in a freezing chamber (or a refrigerating chamber of the refrigerator).
In an air conditioning system, a refrigerating unit operates, refrigerant entering an evaporator evaporates to absorb heat, when cold water in the evaporator is introduced, heat exchange is carried out in the evaporator quickly, the heat is absorbed by the refrigerant, the temperature is reduced to be chilled water, and then the chilled water exchanges heat with treated air through a surface cooler in air conditioning equipment to reduce the temperature of the air.
Therefore, the refrigerating and heating effects of the air conditioner can be greatly influenced by the shortage of the refrigerant. Therefore, the leakage amount of the refrigerant is accurately calculated, and before the leakage amount does not substantially influence the operation of the air conditioner, a user is timely reminded to fill the refrigerant, so that the air conditioner plays a decisive role in stable operation.
The embodiment of the application provides a method for detecting leakage of a refrigerant of an air conditioner, aiming at the condition of low calculation accuracy of the leakage of the refrigerant in the related art, and the calculation accuracy of the leakage of the refrigerant can be greatly improved.
The method for detecting refrigerant leakage of an air conditioner according to the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, a method for detecting refrigerant leakage of an air conditioner according to an embodiment of the present invention may include the following steps 101 and 102:
Wherein, the air conditioner is in the state of steady operation, includes: the working frequency of the compressor is not changed within the preset time.
It can be understood that when the compressor of the air conditioner is operated for a preset time, and the operating frequency of the compressor is not changed during the preset time, it indicates that the air conditioner is in a stable operation state.
Illustratively, when the refrigerant of the air conditioner leaks, the exhaust temperature of the compressor rises, and at the moment, the compressor can perform protective frequency reduction, reduce the working frequency and avoid the condition of overhigh exhaust temperature.
For example, based on the above principle, it may be determined whether the refrigerant of the air conditioner leaks according to whether the operating frequency of the compressor under the current operating environment parameters is normal.
And 102, determining whether the refrigerant of the air conditioner leaks or not according to the comparison result of the current working frequency and the preset working frequency and the target parameter, and determining the leakage amount of the refrigerant under the condition that the refrigerant leaks.
Wherein the target parameters include: indoor ambient temperature, outdoor ambient temperature, indoor fan rotational speed, current operating frequency, the discharge temperature of compressor.
For example, after the current working frequency of the compressor is obtained, the current working frequency needs to be compared with a preset working frequency corresponding to the compressor under the current working environment parameters, and whether the refrigerant of the air conditioner leaks or not is determined according to a comparison result.
It should be noted that, when the current operating frequency of the compressor is less than the preset operating frequency, it indicates that the refrigerant leakage of the air conditioner is large, and has affected the normal operation of the compressor; when the current working frequency of the compressor is equal to the preset working frequency, the refrigerant of the air conditioner may not be leaked, or the leakage amount of the refrigerant of the air conditioner is small, which is not enough to affect the operation of the compressor, and at this time, whether the refrigerant leakage occurs or not needs to be further judged according to other conditions.
For example, in the case where it is determined that the refrigerant of the air conditioner leaks, the specific leakage amount may be estimated by at least one of the above target parameters.
Optionally, in this embodiment of the application, the refrigerant leakage amount under different conditions may be calculated through different parameters.
For example, in the embodiment of the present application, the following two conditions may be determined according to the comparison result between the current operating frequency of the compressor and the preset operating frequency:
case 1:
in case 1, the current operating frequency of the compressor is less than the preset operating frequency, and at this time, the refrigerant leakage amount of the air conditioner is large, and the refrigerant leakage amount can be determined according to the comparison result of the operating frequency of the compressor.
Illustratively, the step 102 may include the following steps 102 a:
and 102a, under the condition that the current working frequency is smaller than the preset working frequency, determining that the refrigerant of the air conditioner leaks, and determining the leakage amount of the refrigerant according to a first ratio of the theoretical working frequency of the compressor corresponding to a first parameter to the current working frequency.
Wherein the first parameter comprises: the outdoor ambient temperature, the indoor fan rotational speed.
For example, as shown in fig. 2, after the air conditioner is started and operates stably, the current operating frequency F1 of the compressor is obtained, and then the current operating frequency F1 is compared with the preset operating frequency F2 corresponding to the current operating environment (i.e., the current operating environment parameter), where if F1 is less than F2, it indicates that the refrigerant leakage amount of the air conditioner is large. At the moment, the working frequency of the compressor can be compared through the outdoor environment temperature and the rotating speed of the indoor fan, and the leakage amount of the refrigerant is estimated according to the comparison result.
It should be noted that, because the performance of the compressors of different models is different, and the change of the operating frequency of different compressors is not completely the same when the refrigerant of the air conditioner leaks, the relationship between the variation of the operating frequency of the compressor and the leakage amount of the refrigerant needs to be determined according to the specific model of the compressor. For example, the operating frequency of the compressor is reduced by 10%, which means that the leakage amount of the refrigerant is 20%.
Case 2:
in case 2, the current operating frequency of the compressor is equal to the preset operating frequency, and at this time, the air conditioner has a possibility of refrigerant leakage, and in order to further determine whether the refrigerant of the air conditioner leaks, it may be determined whether the refrigerant leaks and, specifically, the leakage amount according to the comparison result of the operating frequencies of the compressor.
Illustratively, the step 102 may include the following steps 102b1 and 102b 2:
and step 102b1, determining whether the refrigerant of the air conditioner leaks according to a second ratio of the theoretical indoor exhaust temperature corresponding to a second parameter to the current exhaust temperature of the air conditioner when the current working frequency is equal to the preset working frequency.
And step 102b2, determining that the refrigerant of the air conditioner leaks under the condition that the second ratio meets the preset condition, and determining the leakage amount of the refrigerant according to the second ratio.
Wherein the second parameter comprises: the indoor ambient temperature, the outdoor ambient temperature, the indoor fan rotational speed.
For example, as shown in fig. 2, after the air conditioner is started and operated stably, the current operating frequency F1 of the compressor is obtained, and then the current operating frequency F1 is compared with the preset operating frequency F2 corresponding to the current operating environment, and if F1 is equal to F2, it indicates that there is a possible leakage of the refrigerant of the air conditioner. At the moment, the exhaust temperature of the compressor can be compared through the indoor and outdoor ambient temperatures and the rotating speed of the indoor fan, whether the refrigerant of the air conditioner leaks or not is judged according to the comparison result, and the leakage amount of the refrigerant is estimated.
Illustratively, the step 102 may further include the following step 102 c:
and 102c, under the condition that the second ratio does not meet the preset condition, determining that the refrigerant of the air conditioner is not leaked.
Illustratively, when the discharge temperature of the compressor does not change obviously, the condition that the refrigerant of the air conditioner leaks is determined.
It can be understood that, in the case of refrigerant leakage, the working time of the compressor may be prolonged under the condition of achieving the same cooling/heating effect, and thus the exhaust temperature of the compressor may increase, and when the exhaust temperature increases to a certain degree, the air conditioner may control the compressor to perform protection and down-conversion. Therefore, under the condition that the leakage of the refrigerant is less and the exhaust temperature is not increased enough to cause the frequency reduction of the compressor, whether the refrigerant of the air conditioner leaks or not can be judged according to the exhaust temperature of the compressor.
Optionally, in this embodiment of the present application, when the refrigerant of the air conditioner leaks, different measures may be adopted according to a difference of the leakage amount.
For example, regarding the step 102a, after the step 102, the method for detecting refrigerant leakage of an air conditioner according to the embodiment of the present application may further include the following step 103:
and 103, determining the suggested filling amount according to the leakage amount, and sending a notification prompt containing the suggested filling amount of the refrigerant to a user.
For example, as shown in fig. 2, in the case that the leakage amount of the refrigerant is large, after the leakage amount of the refrigerant is estimated by comparing the operating frequency of the compressor, the user may be prompted by an Application (APP) to leak the refrigerant, and a recommended filling amount of the refrigerant is given.
For example, regarding the step 102b1 and the step 102b2, after the step 102, the method for detecting refrigerant leakage of an air conditioner according to the embodiment of the present application may further include the following steps 104 and 105:
and step 104, recording the current leakage amount and not sending a notification prompt under the condition that the leakage amount is smaller than a preset threshold value.
And 105, determining suggested filling amount according to the leakage amount under the condition that the leakage amount is larger than or equal to the preset threshold value, and sending notification prompt of the suggested filling amount containing the refrigerant to a user.
For example, as shown in fig. 2, when the leakage of the refrigerant of the air conditioner is determined by comparing the indoor and outdoor ambient temperatures and the rotational speed of the indoor fan with the discharge temperature of the compressor, and after the leakage of the refrigerant is estimated according to the comparison result, if the leakage is greater than or equal to 10%, the user is reminded of the leakage of the refrigerant through the APP, and the suggested filling amount of the refrigerant is given; if the leakage amount is less than 10%, reminding is not carried out, but the leakage amount is recorded for the user to inquire.
It should be noted that, because the parameters such as the predetermined operating frequency and the discharge temperature corresponding to the compressors of different models are different, the related data used in the method for detecting refrigerant leakage of an air conditioner according to the embodiment of the present application may be obtained from a server in order to facilitate later updating and maintenance of such data.
According to the method for detecting the refrigerant leakage of the air conditioner, whether the refrigerant of the air conditioner leaks or not is determined through the change of all parameters of the air conditioner in the operation process of the air conditioner. And under the condition that the refrigerant leaks, different measures are taken according to the leakage amount of the refrigerant, so that the influence of the leakage of the refrigerant on the operation of the air conditioner is reduced, and the use experience of a user is improved to a certain extent.
It should be noted that in the air conditioner refrigerant leakage detection method provided in the embodiment of the present application, the execution main body may be an air conditioner refrigerant leakage detection device, or a control module in the air conditioner refrigerant leakage detection device for executing the air conditioner refrigerant leakage detection method.
