A climate control system for an animal house is operated by determining a minimum ventilation curve for required minimum ventilation. A plurality of ventilation stages is created based on the minimum ventilation curve and the plurality of ventilation fans in the climate control system, each stage providing a percentage of the required minimum ventilation. Creating the stages includes prioritizing the ventilation fans to create a selection hierarchy and determining a minimum stage ventilation and a maximum stage ventilation for each stage. Ventilation fans are selected following the hierarchy that provides the desired percentage of the minimum required ventilation. The system advances from a lower stage a higher stage based on ventilation requirements. When it is determined that a fan is not operating, the system returns to the lower stage to substitute ventilation fans.

An odor-removing trap system for removal of noxious gases emanating from cat litter boxes. The present invention provides an apparatus including an enclosure for capturing, filtering and removing noxious gases associated with cat waste products. Such gases rise upwardly within the enclosure wherein the gases are trapped and drawn from the enclosure. In one embodiment the gases are urged into an exhaust conduit disposed in fluid (i.e. air) transfer communication with the enclosure and flow to the exterior of the building by convection, air pressure or by vacuum created by a brushless fan motor. Such fan motor is powered by a battery pack or, alternatively, is electrically connected to an AC power source and can be actuated automatically by a motion detector whenever a cat enters the enclosure. In alternative embodiments the noxious gases are drawn through an air filter assembly including an activated charcoal filter element and absorbed therein.

An animal confinement housing includes an air intake section and an animal confinement section. Air is drawn into the housing through the air intake section and directed through the confinement section to ventilate the confinement section and the animals confined therein. The height of the confinement section can be selectively varied between a raised position of sufficient height to permit personnel and equipment to enter the confinement section and a lowered position that is of sufficient height to accommodate the animals confined therein by reduces the cross-sectional area through the confinement section to increase the air flow rate through the confinement section, without requiring an increase in the rate of intake of air into the air intake section.

An auto-deodorant animal cabinet includes an open front end and a plurality of partitions to form several layers within the cabinet. Each partition comprises a slanting board therein. Two sides of each slanting board are connected to a water inlet pipe and a water outlet connected to a water inlet and an exhaust pipe, respectively. Each exhaust pipe is connected to a processing device for grinding process. Each layer of the cabinet comprises a plurality of cages. The cabinet comprises at a back wall a plurality of slots corresponding to each cage. A fan box covering all the slots is provided at the back wall of the said cabinet. The fan box comprises a ventilation pipe with a fan to expel odor smell in the cabinet.

A method is provided for raising poultry, such as chickens, for food production. In a first preferred embodiment, the method includes the steps of: providing a facility for housing the poultry, providing at least one light-absorbing ventilation fan associated with the facility for ventilating the facility, exposing an interior of the facility to natural light cycles of an outside environment for a first period and regulating light cycles of the interior for a second period, thereby mimicking daylight duration variation representative of seasonal changes for stimulating sexual development of the poultry. In a second preferred embodiment, the method includes the steps of: providing a facility for housing the poultry, providing at least one light-absorbing ventilation fan associated with the facility for ventilating the facility, limiting exposure of an interior of the facility to light to produce a brown-out effect therein for enhancing physical development of the poultry.
摘要:
A modular automatic power flow fresh air inlet comprising a housing having fresh air openings between a source of fresh air and a room, having an adjustable static pressure to be ventilated. The fresh air openings may be controlled by a valve plate pivotally connected to the housing at each opening. The valve plates pivot relative to the static pressure in the room. A cable having first and second ends extends through the housing and is connected to the valve plates via a lanyard. A cable control device for moving the cable between a forward position and a rearward position is connected to the first end of the cable. A cable counter weight is attached to the second end of the cable. Moving the cable toward the forward position places tension on the lanyard, causing the valve plate to pivot from the static position toward to the fully opened position. Moving the cable toward the rearward position relaxes the tension in the lanyard, causing the valve plate to pivot toward the static position. A plurality of fresh air inlets may thereby be connected in series via the cable for regulating an air flow course within a building.
