Abstract: An outdoor unit includes a pressure sensor for detecting an internal pressure of a first pipe. An outdoor unit controller is configured to: receive a switching signal; control an outdoor fan and a compressor to operate in a case where the switching signal instructs the outdoor unit to operate, the compressor operating at a first frequency; acquire a current state of the indoor fan in a case where the on signal instructs the outdoor unit to shut down; and control the compressor and the outdoor fan to operate if the current state of the indoor fan is an operating state, the compressor operating at a second frequency. The second frequency is lower than the first frequency. The current state of the indoor fan is obtained according to the internal pressure of the first pipe.
