Abstract

The invention provides an air conditioner and a refrigerant leakage detection method for the air conditioner. The refrigerant leakage detection method comprises the following steps that S1, the air conditioner is started up, relevant information before operation is acquired, and a pre-operation frequency is acquired according to the relevant information before operation; S2, the air conditioner ispre-operated, and the compressor is controlled to operate according to the pre-operating frequency; S3, compressor suction pipe pressure P11 is acquired after pre-running for t1 hours; S4, the air conditioner judges whether P11 is less than or equal to a preset pressure value or not; if yes, refrigerant leakage occurs, otherwise, the S5 is carried out; S5, the concentration percentage of refrigerant components is obtained in the suction pipe of the compressor; and S6, whether the concentration percentages of refrigerant components are all within a preset numerical range or not is judged; if yes, refrigerant leakage occurs; if no, the air conditioner ends the pre-operation and operates according to the preset mode of the air conditioner. The refrigerant leakage detection method of the airconditioner effectively improves the accuracy of refrigerant leakage detection of the air conditioner and avoids misjudgment.

Description

technical field

[0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a method for detecting refrigerant leakage of the air conditioner. Background technique

[0002] With the progress of today's society and the development of economy, air conditioners, as a relatively important electrical equipment in people's daily life, have entered thousands of households. However, during the installation process and long-term use of the air conditioner, the pipeline may be damaged due to poor sealing, bending, long-term corrosion or other external force majeure, resulting in leakage of the air conditioner refrigerant. Fundamentally, the leakage of refrigerant is reflected by the reduction of refrigerant flow. Insufficient amount of refrigerant will degrade the performance of the air conditioner, make the compressor run in a poor condition, and even damage the compressor in severe cases.

[0003] Most of the current technologies...
