The invention discloses an air conditioner and a control strategy of the air conditioner. The air conditioner includes: a compressor, a reversing unit, a first heat exchanger, a phase change heat storage heat exchanger, a throttling device, a temperature sensor, a human body The sensor, the control module and the box, the compressor, the reversing unit, the phase change heat storage heat exchanger, the throttling device, and the first heat exchanger are connected to form a refrigerant circulation loop, and the The phase change heat storage heat exchanger has a sensor for detecting the content of one phase of the phase change medium, the sensor, the temperature sensor, the human body sensor, and the compressor are all electrically connected to the control module, and the temperature The sensor is used to detect the ambient temperature. The air conditioner of the present invention does not need to release heat to the environment when cooling, and does not need to absorb heat from the environment when heating, which realizes an integrated design and has a high degree of intelligence in operation.
