Compressor protection method for air conditioner

The invention discloses a compressor protection method for an air conditioner, which is characterized by comprising the following operating steps of: 1, starting up, and beginning to count through a counter in the air conditioner, wherein N is equal to 0; 2, running; 3, switching on a compressor relay by using an electric control device of the air conditioner, and beginning to detect the current of the whole machine after t seconds, wherein the value range of the t is 1 to 100 seconds, and steps 4 and 7 are to be executed simultaneously; and 4, judging whether the current is smaller than a safety value I2, if so, entering a step 5, otherwise returning to the step 2. The conventional air conditioner system is not needed to be modified, and a software control part is needed to be modified only, so the compressor of the air conditioner can be ensured not to be burnt out under the abnormal condition and the aim of protecting the compressor is achieved; and the compressor has the advantages of simple and reasonable structure, flexible operation, high safety degree and wide application range.
