The present invention provides stretchable laminates with a flat appearance on the visible surface. The laminates comprise a textile layer, a functional layer, and a plurality of elastic fibers. The plurality of elastic fibers are in a substantially parallel arrangement and the internal distance between adjacent fibers does not exceed the maximum fiber spacing, which depends on laminate thickness in a stretched state. Also provided are garments and footwear comprising the stretchable laminates and methods of producing the stretchable laminates.

A process gas treatment device for a process gas for treating a process material in a process apparatus and a method for treating process gas for the treatment of a process material in a process apparatus during a drying phase and a cooling phase.

According to various aspects, exemplary embodiments are disclosed of blow through direct fired heaters including evaporator coils and/or energy recovery ventilation.

An HVAC system includes a heating element, a discharge air temperature sensor, and a return air temperature sensor. A controller of the HVAC system determines that the HVAC system has been operating in the heating mode for at least a predefined amount of time. The controller receives measurements of the discharge air temperature and the return air temperature. A temperature rise value is determined using the discharge air temperature and return air temperature. If the temperature rise value is less than a predefined minimum threshold value, the controller determines that a first fault of the HVAC system is detected and provides a corresponding alert. If the temperature rise value is greater than a predefined maximum threshold value, the controller determines that a second fault of the HVAC system is detected and provides a corresponding alert.

A portable dehumidifier includes a remote moisture sensor that is capable of being physically positioned at a location that is remote from a portable housing of the portable dehumidifier to sense moisture at the location. In some instances, the remote moisture sensor may be positioned near or on clothing in order to sense the dryness of the clothing and/or positioned near or on floors, walls, furniture, etc., in order sense the dryness thereof in connection with water damage restoration.

An atmospheric water generator includes a refrigeration circuit having an evaporator coil and a condenser coil. The condenser coil is positioned proximate to the evaporator coil, and preheats a flow of atmospheric air as the air is forced through the condenser coil before the air passes through the evaporator coil. Liquid water condensate from the preheated air is generated as the air passes through the evaporator coil and is accumulated in a water collection tank. A second condenser coil cooled by a second flow of atmospheric air supplies refrigerant to the evaporator coil.

An access control system receives a trigger command for controlling a ventilation system; determines that the trigger command includes a lock trigger to hold an entrance door in a closed position; and induces a locking differential air pressure between opposite sides of the entrance door in response to the lock trigger, where the locking differential air pressure is sufficient to bias the entrance door to contact or to increase contact with a door frame in the closed position. The access control system may also determine that the trigger command includes an open assist trigger to ease an opening of the entrance door; and may induce an opening differential air pressure between the opposite sides of the entrance door in response to the open assist trigger, where the opening differential air pressure is sufficient to bias the entrance door to reduce contact with the door frame in the closed position.
