The embodiment also provides a working method of the communication cabinet, which is applied to the communication cabinet, and the working method comprises the following steps:
the controller judges whether the external temperature of the cabinet body 1 detected by the first temperature sensor is lower than a first set value or not, if so, the controller adopts a first working mode; if not, the controller adopts a second working mode;
the first operating mode includes:
when the temperature acquired by the first temperature sensor is lower than a second set value, the second set value is smaller than the first set value, the controller turns off the heat radiation fan 14 and the air conditioning equipment 15, and the cabinet body 1 is cooled in a natural heat radiation mode due to the fact that the temperature outside the cabinet body is lower; if the temperature acquired by the second temperature sensor reaches a third set value, the controller starts the cooling fan 14 and turns off the air conditioning equipment 15, and at the moment, the temperature in the cabinet body 1 is slightly high, and the cooling fan 14 is adopted for cooling; if the temperature collected by the second temperature sensor reaches a fourth set value, the fourth set value is greater than the third set value, the controller starts the air conditioning equipment 15 and closes the cooling fan 14, and at the moment, the temperature in the cabinet body 1 is high, and the air conditioning equipment 15 is adopted for cooling. The starting and closing conditions of the cooling fan 14 and the air conditioning equipment 15 are the temperatures acquired by the first temperature sensor and the second temperature sensor after stabilization. The first set value, the second set value, the third set value and the fourth set value can be set according to the conditions of users, and the heat radiation fan 14 and the air conditioning equipment 15 alternately operate according to different temperatures, so that energy can be effectively saved, and the service life of the equipment is prolonged.
