The current dehumidification method of the closed cabinet wet condensation has the following defects:
1. the fan type dehumidifying has the advantages of low cost, simple installation and low energy consumption. The air convection and the outside drying air exchange to reduce the humidity in the electrical cabinet, and the electrical cabinet is not effective when the environmental humidity is high, so that dust and dirt are easy to enter, and the aim of damp prevention cannot be achieved.
2. The dehumidifying agent is added with the dehumidifying agent, and in the past, a silica gel bag or other water absorbing materials can be hung in the cabinet body, however, in practice, the effect is often not obvious because the water absorbing effect is limited and the absorbed water is difficult to discharge.
3. Heating dehumidifier the heating dehumidifier is through the temperature in the improvement cabinet, only reduces relative humidity in the cabinet to not reduce the water content of cabinet interior air, once ambient temperature changes, moist hot air can the condensation rapidly. But does not solve the problem of condensation in the electrical cabinet. The dehumidifying effect is not obvious, and potential safety hazards exist.
4. The blocking is performed by using the cement, so that the entry of moist air can be reduced, and the entry of moist air cannot be stopped. Summarizing: none of the above methods solves the condensation phenomenon.
