step three, when the first temperature sensor detects that the temperature in the cabinet body is higher than a third preset value, the controller controls to start the negative pressure fan to perform auxiliary cooling; wherein the third preset value is greater than the second preset value;
the heat preservation control method comprises the following steps:
when the temperature detected by the second temperature sensor is lower than a fourth preset value serving as a lower limit value, the controller controls the protective cover to move downwards, so that the cabinet body is located in the closed space of the protective cover; meanwhile, the controller controls the circulating pump to be started, and the underground temperature is transmitted to the cabinet body through the circulation of the liquid.
