Reducing condensation in dimmable window systems

An aircraft window mounting assembly comprising:

• a compliant bezel defining an inner opening, the compliant bezel including an inner wall having a channel;
• a dust cover proximate the compliant bezel;
• an electro-optic element disposed in the opening and configured for reception in the channel of the inner wall, wherein the pressure pane, the compliant bezel, and the electro-optic element define an exterior cavity, and wherein the compliant bezel, the electro-optic element, and the dust cover define an interior cavity;
• a first relief passage in fluid communication with the exterior cavity and the interior cavity;
• and
• a second relief passage in fluid communication with the interior cavity and an expansion bellows mechanism.

An aircraft window mounting assembly comprising:

• a foam bezel proximate a periphery of the pressure pane and defining an inner opening, the foam bezel including an inner wall, an outer wall, an exterior wall, and an interior wall, wherein the inner wall includes a channel;
• an electro-optic element disposed in the opening and configured for reception in the channel of the inner wall, wherein the foam bezel at least partially defines an exterior cavity and wherein the foam bezel also at least partially defines an interior cavity;
• a first relief passage extending through the foam bezel and in fluid communication with the exterior cavity and the interior cavity;
• and
• a second relief passage extending through the foam bezel and in fluid communication with the interior cavity and one of an aircraft interior cabin and an aircraft wall.
