The present invention relates to a ventilation system for pig-raising facilities, comprising: a pig house (110) comprising a plurality of pig rooms (a) in which pigs are raised, and comprising an intermediate ceiling (113) and an upper ceiling (115) which are spaced apart from each other; a pit (120) provided at the bottom of the plurality of pig rooms (a); a plurality of roof exhaust fans (140) arranged at positions corresponding to the plurality of pig rooms (a), along the edge regions of the intermediate ceiling (113); and a plurality of air entry slots (150) provided in a plate surface of the intermediate ceiling (113) at constant intervals. At the front surface of the pig house (110), there are provided a lower window (114) which is provided between the intermediate ceiling (113) and the upper ceiling (115) and through which external air is introduced, and an upper window (116) which is provided between the upper ceiling (115) and a roof (112) and through which external air is introduced. At the rear surface of the pig house (110), lower exhaust fans (117) are provided to face the lower window (114), and upper exhaust fans (118) are provided to face the upper window (116).

A livestock blower apparatus for blowing air through a flexible hose onto an animal. A pair of blower units are enclosed within an interior space of a housing. The blower units are adapted to draw air through housing inlet openings and force it through a Y-shaped conduit out through a housing outlet opening without the air coming in contact with the housing interior space. A cooling fan is provided at a housing cooling inlet opening and blows air into the housing interior space. Another cooling fan is provided at a housing cooling outlet opening and draws/blows air out from within the housing interior space. The blower units are thereby protected from the elements and noise generated by them is muffled by the housing, and the blower units are cooled for minimizing the heat that may be transferred to the air being blown onto the animal.

The device is a hollow enclosure, similar to a hollow tube shape with openings on either end. The openings are covered by a fine screen, to allow air to pass through the center of the device. Further, a small fan is installed in the center of the device, allowing to suck air in from one side, and blow air out of the other side. The device is then placed into a terrarium, vivarium, or similar pet or plant cage to create internal air circulation within the environment.

A collapsible sound reducing pet container when fully assembled forms an enclosure having a generally rectangular volume with manually disassembleable top, bottom, front, rear, left, and right panels. The front panel defines a cutout having an area less than that of the front panel, and at least one of the panels comprises multiple layers of dissimilar soundproofing material. An electric fan, mounted to one of the panels, becomes energized in response to presence of an animal within the enclosure. Each of the top, front, rear, left and right panels is sized to allow all of the panels to be stacked between and enclosed within the top and bottom panels, to collapse the container for transport and storage.

Some embodiments of the present livestock structures comprise a floor, wherein the floor is configured to support livestock housing; a roof, wherein a majority of the roof is substantially parallel to the floor; and one or more supporting structures configured to support the roof; in some embodiments, the floor comprises a non-zero slope. Some embodiments of the present livestock structures comprise a passageway extending a majority of a distance between a first side and an opposing second side of the structure, wherein the passageway is positioned at an elevation that is below an elevation of the floor.

A plenum flooring system installed over high density insulation panels, preventing heat loss to ground and intrusion of ground moisture. The system includes one or more flooring segments, each containing at least one surface opening to the plenum space, and a plenum ventilation system. The ventilation system includes a blower and air inlet openings in seals arranged along the perimeter of the plenum flooring segments at the walls of the interior of a poultry house. The blower withdraws air from the plenum space through the surface opening of the flooring segment and discharges it into the poultry house, creating a continuous flow of air to maintain uniform flooring surface temperatures and remove moisture that migrates to the plenum space from manure on the perforated flooring surface due to moisture gradient, then a refrigerated dehumidifier/air circulation unit to condense moisture in the air and discharges that liquid to the house exterior.

The animal crate cooling system comprises a thermal cover for an animal crate and a cold air unit The cold air unit generates and circulates cool air through the crate. The thermal cover comprises a plurality of thermally insulated panels that surround the sides and top of the crate. One or more apertures in the top of the thermal cover allow air to enter and/or exit the crate. The cold air unit utilizes carbon dioxide gas from an attached CO2 cylinder to make dry ice by blowing the CO2 into a mesh basket within the cold air unit. One or more air moving devices may circulate cool air from the cold air unit over the dry ice and through the crate. The air moving devices may be powered by a battery, which may be recharged using a solar panel.

An odor filter apparatus for a litter box comprising: a rear wall; a first side wall located on one side of the rear wall, and orientated orthogonally to the rear wall; a second side wall located on an opposite side of the rear wall from the first side wall, and orientated orthogonally to the rear wall, the walls configured to rigidly attach to a litter box bottom, a vent located in the rear wall; a filter housing attached to the rear wall, on a side opposite the first and second side walls; an active odor removing element located in the filter housing; a fan assembly housing removeably attached to the filter housing; a blower fan located in the fan assembly housing; a mounting opening in the fan assembly housing; a fan exhaust sealing device attached to the mounting opening.

An environmental control system for controlling environmental conditions within an open interior of an agricultural building includes a main controller, and a plurality of zone systems. Each zone system is configured to control environmental conditions within one of a plurality of zones within the open interior, and includes at least one environmental control device, a temperature sensor configured to output a temperature signal indicating a temperature within the zone, and a smart hub configured to control the at least one environmental control device of the corresponding zone based on low and high setpoint temperatures for the zone issued by the main controller and the temperature signal issued by the temperature sensor of the zone. The main controller is configured to prevent activation of an environmental control device in one of the zones by the smart hub based on an operating condition of an environmental control device in another zone.
