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 climate control system is operated by receiving climate information from climate control input devices at one or more plugin modules. The climate information is communicated from the plugin modules to a main control unit, which determines operating instructions for climate output devices and air inlets. When it is detected that the main control unit is not operational, the control system switches to a standby control unit if so equipped. The climate information is then communicated from the plugin modules to the standby control unit. The standby control unit determines operating instructions for the climate output devices and air inlets based on the climate information. When it is detected that the standby control unit is also not operational, the plugin modules switch to an autonomous mode such that operating instructions for the climate output devices and air inlets are determined by the plugin modules.

A filter assembly including a rectangular inlet frame having a rectangular inlet opening configured to receive a primary filter and optionally a prefilter. The filter assembly may include a rectangular outlet frame and a housing body. The rectangular inlet frame may also be used as a housing by itself to support and house primary filters and prefilters. A gridwork including one or more grid dividers may be used in the rectangular inlet frame to provide 2 or more openings for receipt of filters.

A dust removal-sterilization-deodorization integrated intelligent lightweight device for livestock and poultry houses includes: a transparent housing, a photocatalyst slidably connected to an inner wall of the transparent housing, filter sleeves rotatably mounted on the inner wall of the transparent housing, a flow guide cavity defined in the transparent housing, a fan fixedly connected to a left sidewall of the flow guide cavity, and a flow baffle fixedly connected to an air inlet end of the flow guide cavity. The filter sleeve includes a low-resistance melt-blown fabric, a rutile manganese-zinc layer is laid on an outer side of the low-resistance melt-blown fabric, a skeleton fabric is attached to an outer wall of the rutile manganese-zinc layer, and an outer wall of the skeleton fabric is rotatably connected to the inner wall of the transparent housing. At least two filter sleeves are transversely arranged, and the filter sleeves are tubular.

An automated litter device having: a base; and a chamber configured for retaining a litter and rotatably supported by the support base, wherein the chamber includes: an entry opening so that an animal can enter and exit the chamber; and a waste opening generally opposing the entry opening configured so that an animal waste passes through the waste opening into the base upon rotation of the chamber; wherein the automated litter device includes one or more of: i) one or more sensors located adjacent to the entry opening which are adapted to sense the presence of the animal within the chamber, the presence of the waste in the base, a level of litter in the chamber, a position of the chamber relative to the base, or any combination thereof; ii) a filtering system configured for reducing, eliminating, and/or preventing, malodors building in the base; and/or iii) a litter dispenser in communication with the chamber to transfer some of the litter to the chamber.

The present disclosure is directed to devices and kits configured to displace noxious odors generated by pet waste or excrement from within pet waste receptacles, such as a litter box kept within the pet owner's living space or home to areas existing outside of such owner's living space via a preexisting window therein. More particularly, a flexible, elongated duct is coupled to an exhaust hole in any hooded litter box on one end, and on another end, coupled to an electrically powered fan and universal window vent panel. When the window vent panel is sealedly disposed in a window and the fan is powered on, noxious air within the receptacle is drawn through the exhaust opening in the enclosure, the duct, and an exhaust opening in the window vent panel to an outside of such window.

A ventilation and temperature regulation structure for an animal house, comprising a house body and a temperature regulation device with a culture layer, the house body comprising a temperature equalization device and an exhaust gas extraction device, the temperature equalization device includes a temperature equalization passage passing through the culture layer, several ventilation holes are disposed on the side wall of the temperature equalization passage; and an outlet end of the temperature regulation device is connected with the temperature equalization passage. Such technical solution is to provide a temperature regulation structure for an animal house having good ventilation, waste reduction and good effect of temperature regulation.

A lighting assembly includes a light guide having opposite first and second major surfaces and at least one edge surface extending between the first and second major surfaces, a solid-state light source arranged to emit light into the edge surface of the light guide, and a plurality of integrated optical elements associated with the first major surface to redirect the light emitted by the solid-state light source. The lighting assembly may further include an air circulation device and a heat transfer system configured to transfer heat generated by the solid-state lighting source to a flow of air generated by the air circulation device. The solid-state light source may include light-emitting diodes, laser diodes, and/or organic light emitting diodes configured to produce multiple colors. Also provided is a habitat including the lighting assembly, and related methods.

A plenum flooring system is installed over high density insulation panels, capable of preventing both heat loss to ground and intrusion of ground moisture into the flooring plenum space. The system is comprised of 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 that are arranged along the perimeter of the plenum flooring segments at the walls of the interior of the poultry housing unit. The blower withdraws air from the plenum space through the surface opening of the flooring segment and discharges it into the poultry housing unit chamber, creating a continuous flow of ventilation air to maintain uniform flooring surface temperatures and remove moisture that migrates to the plenum space from manure on the perforated flooring surface due a moisture gradient. The plenum ventilation system further includes a refrigerated dehumidifier/air circulation unit to condense moisture in the chamber air and discharges the condensate liquid to the housing unit exterior.

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.
