[0165] Compared with the first embodiment, step S406 and step S407 are mainly added in the embodiment of the present application, which involves the principle that: for the second heat exchanger, when there is a lack of refrigerant, due to the flow through the second The refrigerant flow rate of the heat exchanger is small, and at this time, the refrigerant will exchange heat too much, causing the temperature of the second coil to be close to the external ambient temperature. Therefore, in the embodiment of the present application, it is added to detect whether there may be a lack of refrigerant by comparing the relationship between the temperature of the second coil and the temperature of the external environment for a period of time after the start of the air conditioner. If the temperature of the second coil is greater than the temperature of the external environment by more than 2 degrees Celsius, Then it is likely that there is a lack of refrigerant, otherwise it means tha...
