Defogging control system and method

A defogging control system, disposed at a refrigeration storage apparatus, the refrigeration storage apparatus including a controller, a compressor, a main casing and a door, the defogging control system comprising:

• a plurality of first heating wires, disposed on the main casing by facing the door;
• a plurality of second heating wires, disposed on the main casing by facing the door and located with respect to the plurality of first heating wires;
• a sensing and driving module, electrically coupled with the controller and the compressor, used for detecting a control signal generated by the controller, generating a start signal for activating the compressor upon when the control signal is determined to be a high voltage signal, generating a stop signal for deactivating the compressor upon when the control signal is determined to be a low voltage signal;
• a timer, electrically coupled with the sensing and driving module, used for detecting a real-time operation time of the compressor upon when the start signal is received, and for recording a preceding operation time of the compressor;
• an environment sensing module, used for detecting an ambient temperature and an ambient humidity;
• and
• a control module, electrically coupled with the environment sensing module, the sensing and driving module and the timer, used for receiving the ambient temperature, the ambient humidity, the real-time operation time and the preceding operation time, controlling respectively each of the plurality of first heating wires to activate at a first power since a first working time start point and each of the plurality of second heating wires to activate at a second power since a second working time start point upon when the start signal is received, so that the refrigeration storage apparatus is prevented from moisture condensation;
• wherein the first power is greater than the second power;
• and when the control module receives the stop signal, the plurality of first heating wires and the plurality of second heating wires are deactivated.
