Method and apparatus for ventilating an interior space, such as a large industrial structure with at least one bay opening. A ventilation system includes an array of M by N fans stacked into a two dimensional (2D) array. A rigid frame supports the array. A seal assembly provides a nominally fluid-tight seal between an outer perimeter of the array and the bay opening. A locking assembly mechanically couples the frame to the bay opening. In some cases, a bay door can be partially retracted and attached to a top of the frame. In other cases, the bay door may be fluidically permeable (e.g., a chain, a screen, etc.) and the array is secured behind a fully closed door. Cooling air is directed out the bay opening at a suitable time, such as overnight. A soft-start motor capability can be used to initiate operation of the array.

A sealing device for a window air conditioner includes a first adjusting member and a second adjusting member. The second adjusting member includes a sliding space. The first adjusting member extends into the sliding space. The second adjusting member is slidable relative to the first adjusting member. One of an outer peripheral wall of the first adjusting member and an inner wall of the second adjusting member includes a plurality of buckles spaced apart from one another along a moving direction of the second adjusting member. Another one of the outer peripheral wall of the first adjusting member and the inner wall of the second adjusting member includes an elastic protruding portion in switchable contact fit with the plurality of buckles during movement of the second adjusting member.
