The invention provides an air conditioner and a detecting method and system for refrigerant leakage in the air conditioner. The air conditioner comprises a compressor, an indoor heat exchanger, an outdoor heat exchanger and a counter. The detecting method for refrigerant leakage in the air conditioner comprises the following steps that after the air conditioner is powered on and started, a current running mode of the air conditioner is obtained; when the current running mode of the air conditioner is a cooling mode or a dehumidifying mode, whether continuous running time of the compressor reaches first preset time t1 or not is judged; if the continuous running time of the compressor reaches the first preset time t1, the inlet air temperature T1 and the coil temperature T2 of the indoor heat exchanger, as well as the inlet air temperature T4 of the outdoor heat exchanger and the air exhausting temperature Td of the compressor are obtained every second preset time t2; whether refrigerant in the air conditioner is leaked or not is judged according to the inlet air temperature T1 and the coil temperature T2 of the indoor heat exchanger, and the inlet air temperature T4 of the outdoor heat exchanger and the air exhausting temperature Td of the compressor. The detecting method can reduce the false alarm rate and the false negative rate of refrigerant leakage.
Description
technical field [0001] The invention relates to the field of air conditioners, in particular to a method for detecting refrigerant leakage in an air conditioner, a detection system for refrigerant leakage in an air conditioner, and an air conditioner. Background technique [0002] Existing air-conditioning and refrigeration systems include a compressor, an outdoor heat exchanger, a throttling device, an indoor heat exchanger, and pre-charged with a certain amount of refrigerant. In the case of no leakage of refrigerant, the air conditioning system can operate normally. If the installation of the air conditioner is not standardized or the refrigerant in the system pipeline leaks slowly for a long time due to vibration and other reasons during later operation, the cooling effect of the air conditioner system will deteriorate. When the refrigerant leakage is serious, the compressor is often burned. Therefore, it is very necessary to detect the leakage of refrigerant in the ai...
