Description

Technical Field

[0001] The utility model belongs to the technical field of animal husbandry environment control, and particularly relates to a positive pressure ventilation device for livestock and poultry houses. Background Art

[0002] With the development of animal husbandry, large-scale animal husbandry has expanded rapidly. Due to the increase in breeding scale and high breeding density, the temperature inside livestock and poultry houses has risen, making it easy for certain epidemics to occur. This requires ventilation and cooling of livestock and poultry houses through positive pressure ventilation devices.

[0003] In the positive pressure ventilation mode of existing livestock and poultry house environmental controllers, the air intake source is usually direct air intake from outside the house, that is, the front end of the positive pressure fan is directly connected to the outside of the house. In cold seasons, the temperature outside the house is low, and directly introducing outdoor air into the house will cause the temperature inside the house to drop rapidly, threatening the health of livestock and poultry, and increasing the insulation consumption cost in production.
