A facility for housing animals such as poultry in a well-ventilated and temperature controlled environment. The facility includes an electronic temperature controller system for providing manual control, as well as programmed operation, over a plurality of side wall curtains, a plurality of tunnel curtains, a plurality of side wall exhaust fans and a plurality of tunnel fans. The system enables the user to instantly visually check the status of, and program operation of, each of these devices by providing a plurality of independent switch controls and indicia for each such device associated with the facility. In alternative embodiments a plurality of heater control switches are included as well as a plurality of auxiliary switch controls for controlling a plurality of optional stir fans. The user is afforded the capability of quickly and easily checking the status of, or programming, the operation of each and every cooling device associated with the facility without resort to computer keyboards or scrolling through numerous menus of menu-driven software systems.

Method and apparatus for controlling temperature within poultry houses

A gasket assembly for use with a ventilation control apparatus in a building ventilation system in a building. The building ventilation system includes inlet and outlet vents and a fan. A plurality of generally narrow continuous openings are formed in a ceiling portion of the building for introducing a ventilating air flow from a first chamber into a second chamber of the building. Air flow through each opening is selectively controlled by a movable baffle device for regulating air flow through the opening into the building. The movable baffle devices are positioned over a ventilation subject, for example a livestock cage, to cooperatively create a desired ventilating air flow pattern in combination with neighboring movable baffle devices. The gasket assembly is employed with the movable baffle device to provide an extremely uniform yet suitably fresh minimum air flow through the building. The gasket assembly includes a dam portion and a curtain portion. The curtain portion channels air flow from the opening to a reduced horizontal opening defined by the dam portion, ends of the curtain portions and the movable baffle.

Rolling ramp gasket assembly

A ventilation control apparatus for use with a building ventilation system in a building. The building ventilation system including input and outlet vents and a fan. An opening is formed in the ceiling of the building for introducing ventilating air flow into the building from the input vent through the opening and out through the outlet vent. The ventilation control apparatus includes a movable baffle and may have a baffle counterbalance attached to the movable baffle. The movable baffle is positioned under the opening for regulating air flow through the top channel into the building. The counterbalance, if used, is attached to the movable baffle and weighted for closing the movable baffle a desired distance relative to the top channel when the fan is not operating and for controllably regulating movement of the movable baffle relative to the top channel when the fan is activated to create a pressure drop across the top channel. The pressure drop creates a force which moves the movable baffle member. The movement of the baffle member lowers the pressure drop and is hence self adjusting. The baffle will move to the position appropriate to the amount of air flowing. Adding weight to the counterbalance will increase the pressure drop.
