9. An anti-condensation method for an air-conditioning electric cabinet is characterized by comprising the following steps:
step 1: the temperature sensor and the humidity sensor detect the actual temperature and the actual humidity in the cabinet body and transmit the actual temperature and the actual humidity to the processor;
step 2: the processor controls the comparator to compare the actual humidity with the condensation point humidity in the memory, and finds out the condensation point humidity equal to the actual humidity value;
and step 3: the processor finds out the condensation point temperature corresponding to the condensation point humidity in the memory;
and 4, step 4: the processor controls the comparator to compare the actual temperature with the condensation point temperature, when the actual temperature is less than or equal to the condensation point temperature, condensation can be generated, the controller controls the air conditioner to heat up or/and dehumidify, when the actual temperature is greater than the condensation point temperature, condensation can not be generated, and the controller does not need to control the air conditioner to heat up or/and dehumidify.
10. The anti-condensation method for the air-conditioning electric cabinet as claimed in claim 9, wherein: in the step 4, after the controller controls the air conditioner to heat up or/and dehumidify, the controller executes:
and 5: the temperature sensor and the humidity sensor detect the actual temperature and the actual humidity in the cabinet body again, and the actual temperature and the actual humidity detected for the second time are transmitted to the processor;
step 6: the processor executes the step 2, the step 3 and the step 4 on the actual temperature and the actual humidity detected for the second time;
and 7: and if the actual temperature detected at this time is less than or equal to the condensation point temperature, repeatedly executing the step 5 and the step 6, and if the actual temperature detected at this time is greater than the condensation point temperature, controlling the air conditioner to stop heating or/and dehumidifying by the controller.
