A stile and rail frame exterior solid core door brings fresh outside air into a structure horizontally through a ventilator assembly. The ventilator assembly includes an upper housing. The upper housing includes a filter for filtering the fresh air and a fan in a fan housing provides a flow of air into the upper housing and through the filter and into the structure horizontally through the door. Air flow through the housing is controlled by a movable damper in the upper housing. An actuator moves the damper in response to electronic input signals. Stale air is exhausted from the structure in a similar manner, through a fan in a lower housing. The upper and lower housings with their fans extend substantially the width of the door between the stiles. Electronic elements are in a housing in the door, and respond to information appropriately sensed by sensor elements placed in the structure. For new construction, the ventilator assembly may be located in a transom area above the door or may be vertically oriented adjacent to a door or as desired.

A protective screen system and method of installation for preventing bugs and insects from passing through a door or window opening, as well as preventing pets, such as dogs and cats from causing damage to a protective screen. The system and method include removing an existing screen from a door or window frame and inserting a protective screen member through a front face of the frame. The protective screen member is a rigid, transparent panel having a plurality of spaced apertures forming a grid pattern. The protective screen member is positioned through an opening of the frame and within a groove thereof such that an entire outer perimeter of the protective screen member is seated within the door or window frame. The protective screen member is secured to the frame via application of a fastener such as an adhesive or tape.

Air gap insulation is a common means of providing thermal insulation from the environment. In many cases the air gap is heated by direct or indirect solar radiation, so ventilating this gap has a cooling effect. The invention cools this gap by integrating moisture-absorption material units that harvest water from the air during the night and provide evaporative cooling during the day. Compared to the ambient air, the daily relative humidity fluctuations in the air gap are more extreme, allowing a significant cooling effect. Furthermore, during the night, humidity absorption on the absorption unit reduces the risk of condensation within the air gap. Additionally the absorption process generates heat, and by using a controller processes of heating, cooling and dehumidifying can be activated when possible and needed.

A window air conditioner includes a housing including a separation groove dividing the housing into two parts, a mounting base movably mounted in the separation groove, and a sealing member connected with the mounting base. The sealing member is fitted with the mounting base by deformation, and the sealing member is configured to be driven by the mounting base to switch between a storage state and a working state. In the storage state, the sealing member is received in the separation groove. In the working state, the sealing member is at least partially outside the separation groove.

A ventilator for a window frame profile, the ventilator having an air intake opening and an air passage opening to ventilate a hollow member of a window frame profile, and a window frame profile system comprising a window frame profile and at least one such ventilator.

A noise management system for a window includes an active noise control (ANC) module and a passive sound absorbing module. The ANC module is disposed in or adjacent a ventilation channel of the window and configured to substantially cancel low-frequency noise entering the ventilation channel. The passive sound absorbing module is disposed in or adjacent to the ventilation channel and configured to absorb both high-frequency noise entering the channel and harmonic sounds generated by the ANC module.

A ventilated window frame comprising; a frame having a plurality of slots along an interior edge and a channel having a first opening and a second opening, a permeable layer fitted within one of the plurality of slots distal to the first edge of the frame, a permeable layer secured within one of the plurality of slots distal to the second edge of the frame, a non-permeable layer secured within one of the plurality of slots between the first and second permeable layers, wherein the first opening of the channel is between the first permeable layer and the non-permeable layer and the second opening of the channel is located between the second permeable layer and the non-permeable layer, a filter inserted within the first opening of the channel, and a fan fitted between the first opening and the second opening of the channel.
