1. Cold room vent is to keep the pressure balance inside and outside the freezer when the temperature of the freezer is below zero, to ensure the free switching of the freezer.
2 included temperature controller can maintain the window temperature of 20-40C, to ensure smooth ventilation will not freeze.
3. Equipped with a stainless steel filter to prevent debris from entering.
4. There is a groove in the middle of the window to prevent water infiltration.
Cold room vent is to balance the pressure inside and outside the refrigerator to ensure that the door freely switch, and its main role is that when the cold room from high to low temperature when the indoor air cooling due to lower, will lead to cold storage due to high outdoor pressure in the cold insulation layer Invaded deformation, in addition to deformation, but also due to internal and external pressure caused by the cold door opening difficulties, the installation of balance window can effectively adjust the pressure balance.
