The use of heat exhaust ventilation in poultry farms

Modern poultry farming is associated with emissions of a significant amount of heat into the atmosphere and from the position of the Kyoto Protocol. The same time, energy is a significant component in the cost of eggs, poultry meat, and all food products from them. The original design of recuperative heat exchangers to minimize aerodynamic drag allowing exhaust air to remove axial fans on the inflow in this case are inevitable radial fans, taking into account the use of the heater. In addition to heat recovery, this vent structure can work both at vacuum and at excessive pressure in the poultry house, for example, in the starting period for broilers. The heat exchanger of the proposed design was tested in the pilot poultry house of OS ‘Cherepovets broiler’, where the installation showed high efficiency by a third to reduce the annual heat consumption compared to other poultry farms located in a similar climatic zone.
