The noise detection device 12 is configured to detect an actual noise value of the air conditioner outdoor unit and transmit the actual noise value to the air conditioner.
Fig. 2 is a schematic diagram of a method for determining a refrigerant quantity according to an embodiment of the disclosure. The method for judging the refrigerant quantity can be executed in the air conditioner or in a server, such as a cloud platform for communicating with the air conditioner. In the embodiment of the disclosure, the scheme is described by taking the processor of the air conditioner as an execution main body.
Referring to fig. 2, the method for determining the amount of refrigerant includes:
s201, the processor obtains an actual noise value of an outdoor unit of the air conditioner.
The actual noise value of the outdoor unit is measured by the noise detection device and sent to the processor of the air conditioner. The noise detection device may be provided in a wall near the air conditioner outdoor unit, a casing surface of the air conditioner outdoor unit, a casing interior, or the like, or may be used as a separate device.
The time period for noise value detection may also be set. The noise value is detected every other period.
The time period is set by the user or according to big data. Therefore, whether the refrigerant is missing or not can be detected in time, and the resource waste caused by continuous detection is avoided.
S202, the processor compares the actual noise value with a preset standard noise value.
The standard noise value may be experimentally measured and then stored for recall.
And S203, when the actual noise value is lower than the standard noise value, the processor judges that the refrigerant quantity is lost.
By adopting the method for judging the refrigerant quantity, which is provided by the embodiment of the disclosure, the following technical effects can be realized: after the actual noise value of the outdoor unit of the air conditioner is obtained, judging whether the refrigerant is missing or not according to the magnitude relation between the actual noise value and the standard noise value. Therefore, in the actual application process, only one parameter of the actual noise value of the air conditioner is detected to judge whether the refrigerant quantity is lower than the standard refrigerant quantity, so that the refrigerant quantity judging process in the air conditioner is greatly simplified.
Alternatively, the acquisition of the actual noise value may be continuous. That is, the noise detecting device continues the actual noise value of the outdoor unit and transmits the noise value to the processor. The comparison of the actual noise value with the standard noise value continues as well. Therefore, the condition of the lack of the refrigerant quantity can be detected at the first time, so that a user or related personnel can make corresponding operation in time, and negative influence of the lack of the refrigerant quantity on the use of the air conditioner is avoided.
Alternatively, the actual noise value may be obtained intermittently. In particular, the acquisition of the actual noise value may be periodic. That is, the noise detecting device periodically detects an actual noise value of the outdoor unit and transmits the actual noise value to the processor. Or, the noise detecting device continuously detects the actual noise value of the outdoor unit and periodically transmits the actual noise value to the processor. The comparison of the actual noise value with the standard noise value will be done periodically. Thus, the refrigerant quantity judgment can be ensured, and the resource consumption can be reduced.
Optionally, the standard noise values are multiple, and respectively correspond to different working conditions, such as a refrigerating working condition, a heating working condition and the like.
Optionally, the processor compares the actual noise value with a preset standard noise value, including: and comparing the actual noise value under the current working condition with the corresponding standard noise value. Specifically, the processor invokes a standard noise value corresponding to the current operating condition, and compares the actual noise value with the standard noise value. Therefore, the judgment of the refrigerant quantity can be carried out in the normal use process of the air conditioner, the influence on the user is small, and the user experience is good.
Optionally, the processor compares the actual noise value with a preset standard noise value, and further includes: the actual noise values under the multiple conditions are compared with the corresponding standard noise values. Specifically, the air conditioner is adjusted to N different working conditions, the processor obtains N actual noise values, and the obtained N actual noise values are compared with standard noise values under corresponding working conditions one by one. Therefore, the error is reduced, and the judgment of the refrigerant quantity is more accurate.
Optionally, S203, where the actual noise value is lower than the standard noise value, the processor determines that the refrigerant quantity is missing, including: and when the N actual noise values are smaller than the corresponding standard noise values under the condition that the N actual noise values are measured, the processor judges that the refrigerant quantity is absent. In this way, the refrigerant is determined to be absent only when all detected conditions meet the refrigerant absence condition, and erroneous determination can be reduced.
Optionally, S203, where the actual noise value is lower than the standard noise value, the processor determines that the refrigerant quantity is missing, further includes: and when the M actual noise values are smaller than the corresponding standard noise values under the condition that the measured actual noise values are N, the processor judges that the refrigerant quantity is absent. Wherein M is less than N. In this way, the influence of individual situations that the actual noise value is not smaller than the standard noise value can be avoided, and erroneous judgment is effectively avoided.
Fig. 3 is a schematic diagram of a method for determining a refrigerant quantity according to an embodiment of the disclosure. The method for judging the refrigerant quantity can be executed in the air conditioner or in a server, such as a cloud platform for communicating with the air conditioner. In the embodiment of the disclosure, the scheme is described by taking the processor of the air conditioner as an execution main body.
Referring to fig. 3, the method for determining the amount of refrigerant includes:
s301, the processor obtains an actual noise value of an outdoor unit of the air conditioner.
S302, the processor compares the actual noise value with a preset standard noise value.
S303, when the actual noise value is lower than the standard noise value, the processor judges that the refrigerant quantity is lost.
S304, the processor calculates the refrigerant missing proportion according to the actual noise value and the standard noise value.
By adopting the method for judging the refrigerant quantity, which is provided by the embodiment of the disclosure, the following technical effects can be realized: after the actual noise value of the outdoor unit of the air conditioner is obtained, judging whether the refrigerant is missing or not according to the magnitude relation between the actual noise value and the standard noise value. Therefore, in the actual application process, only one parameter of the actual noise value of the air conditioner is detected to judge whether the refrigerant quantity is lower than the standard refrigerant quantity, so that the refrigerant quantity judging process in the air conditioner is greatly simplified. In addition, a specific refrigerant missing proportion can be calculated according to the actual noise value and the standard noise value, and the method can be used for guiding actual refrigerant filling operation.
Optionally, S304, the calculating, by the processor, the refrigerant missing proportion according to the actual noise value and the labeling noise value includes:
the processor calculates the refrigerant missing proportion。
Wherein A is a standard noise value, T is an actual noise value, and K is a refrigerant reference value.
Therefore, the accurate refrigerant loss ratio can be obtained, and specific values are provided for users or related personnel, so that different operations can be executed according to the values of the refrigerant loss ratio.
The sources of the standard noise value a are mainly three: fan noise, compressor noise, and refrigerant tones. Therefore, the refrigerant sound reference value K is the measured standard noise value A minus the fan noise value and the compressor noise value under the corresponding working conditions. The refrigerant sound reference value K under different working conditions can be obtained through tests, and then the measured K value is stored for calling. Thus, the calculated refrigerant missing proportion is more accurate.
Alternatively, different noise sources may be distinguished by analyzing the frequency of the noise values. The fan noise and the compressor noise have lower frequency and the refrigerant sound frequency is higher. In the absence of the refrigerant, the refrigerant tone frequency increases. Therefore, noise values from different sources can be further distinguished, and the judgment of the refrigerant quantity is more accurate.
Fig. 4 is a schematic diagram of a method for determining a refrigerant quantity according to an embodiment of the disclosure. The method for judging the refrigerant quantity can be executed in the air conditioner or in a server, such as a cloud platform for communicating with the air conditioner. In the embodiment of the disclosure, the scheme is described by taking the processor of the air conditioner as an execution main body.
Referring to fig. 4, the method for determining the amount of refrigerant includes:
s401, the processor obtains an actual noise value of an outdoor unit of the air conditioner.
S402, the processor compares the actual noise value with a preset standard noise value.
S403, when the actual noise value is lower than the standard noise value, the processor judges that the refrigerant quantity is lost.
S404, the processor calculates the refrigerant missing proportion according to the actual noise value and the standard noise value.
S405, when the refrigerant missing proportion is greater than or equal to a refrigerant threshold value, the processor sends a prompt instruction.
By adopting the method for judging the refrigerant quantity, which is provided by the embodiment of the disclosure, the following technical effects can be realized: after the actual noise value of the outdoor unit of the air conditioner is obtained, judging whether the refrigerant is missing or not according to the magnitude relation between the actual noise value and the standard noise value. Therefore, in the actual application process, only one parameter of the actual noise value of the air conditioner is detected to judge whether the refrigerant quantity is lower than the standard refrigerant quantity, so that the refrigerant quantity judging process in the air conditioner is greatly simplified. In addition, a specific refrigerant missing proportion can be calculated according to the actual noise value and the standard noise value, and the specific refrigerant missing proportion is used for guiding refrigerant filling operation.
Optionally, the value range of the refrigerant threshold is [3%,8% ]. Specifically, it may be 4%, 5%, 6% or 7%. The influence of the refrigerant deficiency in the range on the use of the air conditioner is negligible, so that frequent sending of prompts to users can be avoided. Refrigerant filling can be avoided when unnecessary, and user operation is simplified.
Optionally, the processor sending the hint instruction includes: the air conditioner is electrically connected with other terminal equipment and sends prompt instructions to the other terminal equipment. The terminal equipment can be a smart phone end, a computer end and the like of a user, can be intelligent household appliances such as an intelligent refrigerator and an intelligent sound box, and can also be a prompt lamp and the like. For example, the intelligent sound box can be controlled to emit preset prompt tones and the like. Or control the indicator light to light up.
Fig. 5 is a schematic diagram of a method for determining a refrigerant quantity according to an embodiment of the disclosure. The method for judging the refrigerant quantity can be executed in the air conditioner or in a server, such as a cloud platform for communicating with the air conditioner.

Referring to fig. 5, the method for determining the amount of refrigerant includes:
s501, the processor obtains an actual noise value of an outdoor unit of the air conditioner.

S504, the processor calculates the refrigerant missing proportion according to the actual noise value and the standard noise value.
S505, the processor calculates the filling amount according to the refrigerant missing proportion.
By adopting the method for judging the refrigerant quantity, which is provided by the embodiment of the disclosure, the following technical effects can be realized: after the actual noise value of the outdoor unit of the air conditioner is obtained, judging whether the refrigerant is missing or not according to the magnitude relation between the actual noise value and the standard noise value. Therefore, in the actual application process, only one parameter of the actual noise value of the air conditioner is detected to judge whether the refrigerant quantity is lower than the standard refrigerant quantity, so that the refrigerant quantity judging process in the air conditioner is greatly simplified. In addition, the accurate refrigerant filling amount can be calculated, and related personnel can conveniently add the refrigerant according to the refrigerant filling amount.
Optionally, S505, the processor calculates the filling amount according to the refrigerant deficiency ratio, including:
the processor obtains standard refrigerant filling quantityM0And calculate the perfusion volumeM=B*M0。
Wherein B is the refrigerant missing proportion.
Here, the standard refrigerant filling amount is stored in a memory of the air conditioner before leaving the factory, and can be directly called when in use. This value is directly related to the model of the user's air conditioner. For example, if the refrigerant is R410A refrigerant, the filling amount is about 800-1000 g when the power is 1 piece, about 800-1000 g when the power is 2 pieces, and about 1200-1500 g when the power is 3 pieces.
Optionally, the air conditioner is connected with a display screen. The processor sends the refrigerant missing proportion and the filling quantity to the display and the display shows the refrigerant missing proportion and the filling quantity. Therefore, a user or related maintenance personnel can intuitively know the missing condition of the refrigerant quantity, and further, the refrigerant quantity is regulated more accurately.
