摘要:
A spray device including a fan located in a housing provided with an air outlet guide for generating an air stream having a predetermined velocity. A nozzle unit for the discharge of liquid therefrom, producing a mist stream capable of being propelled to a predetermined location and having a measurable and controllable lateral dimension at the predetermined location. The spray device is used particularly for moistening cattle, especially cows, in sheds, and taking into account the effect of the wind. Rows of sprayers project water sprays directed toward the cattle. The sprayers may be angularly shifted to take into account the deviating effect of the wind. A processor calculates the angular shift that is needed for the existing wind direction and intensity. All the sprayers concurrently receive the angular shift, which is transmitted to the first sprayer from a control station and successively from each sprayer to the next.
摘要:
A heat exchange system including ductwork for transporting fresh, preheated air into the interior space of a building. The ductwork has a header and at least one lateral in fluid communication with the header. The lateral includes a trunk passing through an opening in the exterior wall of a building. The trunk extends upwardly into the interior space of the building from the opening to an apex whose elevation is higher than the opening. A branching arm extends outwardly from said apex and has an open, terminal end remote from the trunk that serves as an air outlet. A tubular sleeve loosely encloses the trunk from the apex downwardly through the opening in the exterior wall so as to form an annular space between the trunk and the sleeve through which air is exhausted from the building. Air passing through the annular space conducts heat to the trunk, warms the trunk, and preheats the air within the trunk being blown into the building. A fan is connected to the header for blowing fresh air from the exterior of the building into the header and through the lateral into the building.
摘要:
A refrigerated water pumping system provides high-pressure refrigerated water to misting nozzles situated in a livestock enclosure for housing livestock and adapted for converting the high-pressure refrigerated water into a fine mist or fog of water droplets at a target water temperature for evaporation in the enclosure to provide cooling of the enclosure to a target enclosure temperature. The system comprises a pump and a post-pumping heat exchanger, with the water being pumped by pump into high-pressure water. The high-pressure water is subsequently refrigerated into high-pressure refrigerated water having the target temperature by absorption of a target heat from the water by a refrigerant in the post-pumping heat exchanger, including any heat absorbed by water during pumping in pump.
摘要:
A livestock cooling apparatus comprising an electrically-powered fan, which is capable of oscillating 360 degrees. The apparatus may be used in conjunction with a programmable cooling system for livestock which allows each fan in the system to be programmed to sweep a designated area according to observed environmental conditions or according to the time of day. The cooling apparatus may further comprise a mist ring for injecting water into the airstream created by the fan to provide for evaporative cooling of the livestock.
摘要:
A ventilation system comprising ducts for injecting air into and exhausting air from a room, said ducts extending side by side separated by a common partition which incorporates an opening between the ducts in which a damper member is arranged to be movable between two extreme positions, in one of which it closes the opening and in the other of which positions it blocks both ducts and opens for full recirculation of the return air from the ventilated room. A layer of heat conductive material is arranged on the inner side of the outer wall of the injection duct, said layer extending from the level at which the damper member contacts the outer wall of the injection duct in the extreme position, in which both ducts are blocked. The layer may have form of a liner member arranged on the inner side of the injection duct and extending also into the exhaust duct.

In an exemplary embodiment, an Environmental Optimization System (“EOS”) provides a system for the intelligent control and monitoring of a poultry or livestock house environment through the utilization of a solar thermal collection system, a variety of environmental and livestock behavior sensors, apparatus for controlling the thermal collection and existing interior heating/air conditioning/ventilation (“HVAC”) systems, and Internet or cloud based intelligent control and monitoring capabilities of the system. In various embodiments central sensor data aggregation is utilized to provide improved optimization control for individual structures based on data from multiple structures.
摘要:
An enclosure for controlling the interior temperature of an outdoor equipment enclosure or a human-or animal-occupied structure, utilizing a quantity of water for thermal transfer and thermal mass. The enclosure is divided into a lower main chamber and an upper small chamber containing the water, the two chambers are in thermal contact, and the water in the upper chamber is in thermal contact with the roof of the enclosure.

摘要:
A ventilation system comprising ducts for injecting air into and exhausting air from a room, said ducts being separated by a partition incorporating an opening between the ducts in which a heat conducting damper plate, both surfaces of which are provided with coatings of an insulating material, is movably arranged to adjust the ventilation. The insulating coating of the surface facing the injected air flow covers the plate completely absent from a peripheral area of the part of the plate located in the injection duct, whereas the coating on the opposite surface covers the part of the plate located in said injection duct right to the peripheral edge of the plate and leaves the part of the plate located in the exhaust duct uncovered.
摘要:
A fan for the ventilation of buildings, e.g. stables, comprising two concentrical tubes in which two sets of interconnected concentric fan vanes are disposed so as to perform an injection of air through the outer tube and an exhaust of air through the inner tube, a bypass being provided between the inner and the outer tube through a first damper which is coupled to a second damper in the outer tube and as the case may be also to one in the inner tube, in such a way that when the first damper is opened the other or others is or are closed and vice versa.
