Description

The invention relates to the field of agriculture, in particular to industrial poultry, devices for creating a microclimate in industrial premises.

Known devices for creating a microclimate when keeping birds and animals in rooms, including air ducts with distribution manifolds (Selyansky V.M., Gavrilenko S.N., Vasiliev V.G. Collection of ventilation schemes for poultry facilities. - M., 1969; Starchikov N .I. Technology for keeping breeding chickens in cell batteries. - M.: Rosagropromizdat, 1989).

A disadvantage of the known devices is that part of the clean air is not used for its intended purpose to maintain the optimal microclimate directly in the cells, but moves in the direction of the exhaust ducts, without reaching the cells.

The electric lighting system with the upper location of the lamps does not provide uniform standard illumination in the cells of especially the lower tiers (Akatova EV, Znamensky VG Improving the lighting of poultry buildings. - J. Lighting, No. 7, 1990, pp. 7-8) .

These shortcomings adversely affect the microclimate in the cells.

Known device for creating a microclimate in poultry houses according to ASSSSSR No. 1122282, class. A 01 K 31/06, publication 07.11.84, BI No. 41, including cages for poultry, supply air distributors with downward-facing air outlet openings and inducers of air ventilation (adopted as a prototype).

The known device has disadvantages - the drivers of air ventilation are located under the ceiling and do not provide effective air exchange in all tiers of cells. The electrical energy consumed by the luminaires is mainly spent on heating the luminaire itself. The air heated by the body and lamp of the fixture rises upward, and since the fixtures are located near the ceiling, the stimulating effect of the heated air flow is insignificant and only in the area of the upper tiers, practically without affecting the air exchange in the cells of the lower tiers.

At the same time, the ceiling lighting system for cell batteries does not allow to create uniform illumination of cells in the lower tiers. These disadvantages reduce the effectiveness of using known methods and devices to create the optimal microclimate in poultry houses, which leads to a decrease in bird productivity.

The technical solution to the problem is to create a method and device for combined ventilation and local illumination of the intracellular space and the premises of the house in order to maintain optimal microclimate parameters, save energy and increase bird productivity.

The problem is solved in that the optimal microclimate system in cell batteries is created by forming in the house an additional internal air circulation in a vertical plane from floor to ceiling using additional vertical air ducts that draw air from under the cell space of the lower tiers of the cell batteries, and inducing air circulation in vertical ducts is carried out by using the heat of light sources placed in the lower floor of the air ode and at the same time used for local lighting of cell batteries.

New in the proposed method is the creation of a system of additional internal air circulation in the vertical plane with the help of additional vertical air ducts with the induction of circulation by their built-in lighting systems, which are simultaneously used to illuminate the cells.

The essence of the method is illustrated in figure 1, which shows a diagram of the creation of a microclimate in the house. The method includes cell batteries 1, passageways between cells 2, supply air distributors 3, exhaust fans 4 and additional air ducts 5 combined with lighting installations 6.

The way to create a microclimate in poultry houses is implemented as follows. Clean air through the supply air distributors 3 is fed into the room and enters the aisles 2 and cells 1, but when it encounters heavier layers of air, it quickly loses pressure, does not reach the floor and lower tiers of the cells. Similarly, the existing ceiling lighting system cannot provide normal illumination in the cells. To eliminate these disadvantages, additional vertical ducts 5 with lighting installations 6 are installed.

When you turn on the supply air distributors 3 and lighting units 6, clean air creates additional pressure in the passages between cells 2. Air enters from the cell space in the lighting units 6 and, heated by light sources, rush up the air duct 5, creating a vacuum in its lower part, where contaminated air is drawn in from the lower tiers of the cell batteries and subcellular space.

Heated air, mixing with cold, through the duct 5 rises to the ceiling, in the area of operation of the exhaust fans 4, and is removed from the house. The reduced air pressure at the floor facilitates the penetration of fresh air into the lower cells, and the lamps provide uniform illumination of the cells.

The method is implemented using a device for creating a microclimate in houses. The problem is solved in that the device in the form of an air duct is installed vertically on the floor and is equipped with air inlets for taking air from under the cell space, as well as light windows directed along the tiers towards the cell batteries, and a lighting installation is placed inside the air duct in such a way that between the outer surface of the box of the lighting installation and the inner surface of the duct an air gap is formed sufficient to circulate the ventilated air . The lighting installation is made in the form of a rigid sealed box with a reflective inner surface, having light windows that coincide with the light windows of the duct and bounded from below by heat-resistant glass, and from above by a reflective screen. In this case, the light source is located in the floor of the duct under the duct and is equipped with a reflector with holes for the entry of cold air and the exit of warm air into the gap between the duct and the duct.

New in the proposed device is that the additional duct is installed vertically on the floor, is made with light windows and is equipped with air inlets located at the floor. New is that the lighting installation is located inside the duct with a gap for the passage of air and is equipped with a reflector with holes for circulating heated air and feeding it into the gap between the duct and the box of the lighting system, while illuminating the cell batteries.

The essence of the device for creating a microclimate in poultry houses is illustrated by the drawing, where figure 2 shows its diagram.

The device includes cell batteries 1, to which an additional vertical duct 5 with a lighting unit is attached 6. The duct is equipped with air inlets 7 and light windows 8. The duct body 5 forms an air gap 9 relative to the box 10 of the lighting unit 6. The box 10 is bounded below by heat-resistant glass 11, and on top of the screen 12. A light source 13 is installed in the reflector 14 having openings 15 for the supply air and openings 16 for supplying heated air to the gap 9.

The device operates as follows. When the light source 13 is turned on, the air contained in the reflector 14 is heated. The heated air through the holes 16 enters the gap 9 and rises through the duct 5, creates a vacuum in the reflector 14, due to this, air from the lower tiers and the subcellular space through the air inlets 15 enters the reflector 14 and, when heated, maintains air circulation in the duct 5.

Thus, the stagnant air of the lower tiers of the cell batteries is directly removed into the exhaust ventilation zone 4, and fresh air enters its place, creating an optimal microclimate in the cells and the house.

At the same time, the light from the light source 13 penetrates through the glass 11 into the box 10 of the lighting unit 6 and, reflected from the walls of the box 10 and the screen 12, enters the light windows 8, illuminates the cell batteries 1, creating uniform illumination in the cells of all tiers.
