A structure for sheltering and cooling livestock may include a concrete floored barn having an improved evaporative cooling system. The cooling system may include a misting stack having air inlets, a mixing chamber, and three cooling zones wherein the cooling zones correspond to three different temperature ranges. Each of the cooling zones may include a plurality of nozzles which produce a mist. As air passes through the mixing chamber, the mist may evaporate and cool the air. The cooling system may further include a plurality of large exhaust fans located at an end of the barn distal from the misting stack. The fans may draw the cool air through the barn, over and around the livestock, and out of the barn.

A ventilation system for a housing structure with a plurality of air vents including: vent control modules configured to control and actuate opening and closing of at least one air vent of the plurality of air vents; an electro-mechanical drive unit mechanically coupled to each of the plurality of vent control modules and providing mechanical power thereto, the drive unit including a motor and a drive shaft, the drive shaft being disposed parallel to the axis of the air vents; a control unit, in communication with the drive unit and the plurality of vent control modules, configured to control the drive unit and individually control each of the vent control modules; the vent control modules use the mechanical power of the drive unit to individually effect the opening and closing of each respective vent of the plurality of air vents.

A compact conditioning system for controlling a volume, comprises: (a) at least one light source, said light source being coupled with a replaceable focusing lens; (b) at least one fan; (c) at least one temperature sensor; (d) control circuitry adapted to receive inputs from said sensor(s) and/or from a user, and to operate said light source(s) and/or said fan(s) as a result thereof; and (e) a housing suitable to house said light source, fan and control circuitry and adapted to be positioned at the top of a structural element defining a closed space.

A fan for use in agriculture which has a BLDC motor which allows for varying the speed of the fan to vary the airflow rate of the fan and vary the efficiency of the fan. A ventilation system for use in a livestock confinement building to maximize a rate of growth of the livestock. A process for maximizing the growth of livestock in a livestock confinement building by controlling the airflow in the livestock confinement building.

An apparatus for collecting a gaseous pollutant from air may comprise multiple vertical panel-beds each containing a solid sorbent; a fan to pass the air through the multiple vertical panel-beds and over the solid sorbent; an outlet gate configured to release the solid sorbent from the multiple vertical panel-beds after the fan passes the air over the solid sorbent; a regeneration vessel configured to regenerate the released solid sorbent by recovering the gaseous pollutant from the released solid sorbent; and a conveyor configured to return the regenerated solid sorbent to the multiple vertical panel-beds.

An animal shelter for reducing noise experienced by an animal is provided. The animal shelter may include one or more side panels creating a substantially enclosed area, a bottom panel coupled to said one or more side walls, and a grounding mat coupled to the bottom panel of the shelter, and configured to dissipate static charge. At least one of the one or more side panels and bottom panel may include an exterior layer of sound-absorbing foam. A fan may be included to direct cold air into the shelter to elevate the barometric pressure.

The power barn system provides a way to eliminate greenhouse gas (GHG) emissions from livestock. The power barn system seals and traps the methane gas that is emitted from the livestock and converts the methane into electric power and carbon dioxide to enhance plant growth. The power barn system uses PV solar arrays and plastic sheeting to make sealed, airtight structure. The carbon dioxide is provided to greenhouse areas. The plants use the carbon dioxide and release oxygen, thereby eliminating most greenhouse gas emissions from livestock. The power plant uses the methane at peak times at night while solar panels supply power during the day producing zero emission meat and 24/7 electricity at better than market rates.

Disclosed is a self-adaptive precise ventilation system for a livestock and poultry house. The system comprises an air pipe, an adjusting assembly, a camera shooting assembly, air flow test pieces and a controller; the air pipe and the air flow test pieces are all arranged above fence areas, the camera shooting assembly is installed on one side of each of the air flow test pieces, and the adjusting assembly is connected together with the air pipe through connecting ropes; a plurality of air supply outlets are formed in the air pipe, and each air supply outlet is provided with a valve; and the camera shooting assembly monitors the air flow conditions in the livestock and poultry house and the information of in-fence areas, and transmits the them to the controller so as to determine the opening degrees and the orientations of the air supply outlets and realize precise air supply.

The present disclosure provides methods for enabling an individual having a cat allergy to have a cat as a pet. Such a method can include quantitatively determining a threshold in the individual for an environmental level of an allergen produced by the cat and selecting a cat or a breed of cat that creates an environmental level of the allergen that is less than the threshold. Additionally, such a method can include lowering the allergens disseminated by the cat by treating the environment inhabited by the cat during a time period where the cat expresses elevated allergens.
