Electronic cooling dew condensation prevention system and its condensation prevention method

摘要

The present invention discloses an electronic cooling condensation prevention system and a condensation prevention method thereof. The system includes a test room, an electronic cooling strip, a temperature sensor, a temperature and humidity sensor, a cooling strip control unit and a main controller. The main controller is electrically connected to the temperature sensor, the temperature/humidity sensor, and the cooling piece control unit. The main controller can calculate the dew point value of the air in the test chamber based on the temperature and humidity inside the test chamber collected by the temperature and humidity sensor, and when the dew point value of the air is higher than a predetermined threshold value. First, the cooling piece control unit is controlled to reduce the operating number of the electronic cooling piece or the output power of the electronic cooling piece. The predetermined threshold is 0
