Description

The invention relates to poultry, in particular to heating and ventilation systems for creating a microclimate in livestock and poultry facilities.

A device for creating a microclimate in a poultry house is known (SU 1122282 A, IPC A01K 31/06, 11/07/84. Bull. No. 41), including cages for birds, passageways for cell batteries, supply air diffusers with downward-directed air outlets, inducers of upward-directed air convection installed above the aisles along their length.

The disadvantages of this device is that a large amount of heat is removed from the room when it is ventilated and thrown out.

Closest to the claimed technical solution, taken as a prototype, is a device for creating a microclimate in a house (SU 1308295 A2, IPC A01K 31/06, 05/05/87. Bull. No. 17), containing bird cages, passageways for cell batteries, supply air ducts, drivers of upward air convection installed above the aisles along their length, distribution manifolds, recirculation ducts, fans.

The disadvantages of this device are: 1 - only part of the warm air is supplied to heat the supply air; 2 - heated air is supplied to the supply air ducts without going through a cleaning system, and is mixed with clean air; 3 - air ducts, recirculation channels, fans are located in the room itself.

The purpose of the invention is the reduction of energy consumption to create the optimal temperature and humidity conditions in the house due to the use of heat generated by the bird.

This goal is achieved by the fact that in order to reduce energy consumption to ensure an optimal microclimate, the house, including a room where bird cages are located, passages between cell batteries, supply ventilation ducts, air ducts, fans, is supplemented by a heated technological room (attic) located above the house, in which a supply and exhaust system of air ducts and heat exchangers is installed, consisting of an exhaust duct, the inlet of which is connected to a centrifugal fan installed in the end wall of the poultry house (dirty zone), and the outlet is located in the technological room, and the supply air duct, the inlet of which is connected to a centrifugal supply fan located in the opposite end wall of the technological room (clean zone), and the exit is in the house. At the same time, a chamber-type air purification apparatus with a corona discharge precipitator is installed at the inlet of the exhaust duct into the technological room. In addition, axial exhaust fans are installed in the end wall of the house and the technological room (dirty zone).

As a result of the search, the authors did not find a device for creating a microclimate in the poultry house, which contains an insulated technological room with a supply and exhaust system of air ducts and heat exchangers located in it and an exhaust air purification system that can reduce energy costs by using the heat generated by the bird in the cold season and create optimal temperature and humidity conditions in the warm season due to the removal of excess heat, which allows us to draw conclusions about the conformity of the declared about a technical solution to both the criterion of "novelty" and the criterion of "inventive step".

The drawings show: the proposed device for the cold (figure 1) and the warm period of the year (figure 3), a longitudinal section of the house and the technological room (figure 2).

A device for creating a microclimate in poultry houses, including a poultry house 9, in which bird cages are located, passageways between cell batteries (not shown), supply ventilation ducts 3 located in the longitudinal walls of the house and having automatic shutters, air ducts 4; 5, fans 1; 2; 6; 8. The device contains an insulated technological room 10 located above the house, in which a supply and exhaust system of air ducts and heat exchangers is installed, consisting of an exhaust duct 4, the inlet of which is connected to a centrifugal fan 1 installed in the end wall of the house (dirty area), and the outlet is located in the technological room 10, and the supply air duct 5, the inlet of which is connected to a centrifugal supply fan 6 located in the opposite end wall of the technological room niya (clean zone), and the exit is in the house of the house, while axial exhaust fans 2 are installed in the end wall of the house and the technological room; 8, and at the inlet of the exhaust duct 4 to the process room 10, an air purification apparatus 7 of chamber type with a corona discharge precipitator is installed.

The device in the cold period works as follows.

Warm air from the house by 9 centrifugal exhaust fans 1 through the exhaust ducts-heat exchangers 4 is fed into the technological room (attic) 10. As it moves through the exhaust ducts, the air gives off its heat. At the inlet of the duct 4, exhaust air is supplied to the purification apparatus 7 of the chamber type with a corona discharge precipitator, and then, passing through the ducts, it is discharged into the process room, giving it the remaining heat. In the adjacent supply air ducts-heat exchangers 5, the passing air is heated by the heat given off by the exhaust ducts 4 as it moves. At the outlet of the supply air ducts 5, the air has a positive temperature. The supply ventilation ducts 3 located in the longitudinal walls, some of which are closed during the winter period, are equipped with automatic dampers that are regulated depending on the air temperature in the house, maintaining the air temperature at a predetermined level. Axial fans 2; 8 during the cold season are partially closed. The device in the warm period works as follows. Axial attic fans 8 create air movement throughout the technological room 10, thereby removing excess heat received through the ceiling and roof. Excessive heat from the house 9 is removed by axial exhaust fans 2.

The use of this device provides an optimal microclimate in cold and warm periods of the year with virtually no additional energy costs.
