|
| Dehumidification |
Freezing and dehumidifying by the refrigeration system (the air in the box passes through the evaporator below the dew point temperature, and water is precipitated). *Choose evaporator fins with hydrophilic membrane treatment, better dehumidification performance, because the water tension of the hydrophilic membrane aluminum fins is small, the water droplets from air condensation are easy to slip off, and it is not easy to produce obstructive water bridges in the fin gap. Thereby greatly improving the dehumidification efficiency!
