(1) Existing problems:

Environmental control equipment including fans, air windows, water curtains and controllers, etc., will also encounter many problems in production, such as winter chicken house heating problems, chicken house dry, dusty, how to control respiratory diseases and dust problems, large chicken house environment is unbalanced, chicken house front end ventilation dead angle problems.

(2) Solution:

Some people think that in response to the drying and heating problems of chicken coops in winter, the air can be heated and humidified at the air inlet of the chicken coop to prevent air drying. The use of coal-fired boilers for heating in brood houses is more economical, but it does not meet environmental protection requirements, the price of gas is high, and the air quality in the house is poor, so you can consider the use of electric heating.

It has been pointed out that the environment in the chicken house is unbalanced, the existence of ventilation dead angle is related to the effective ventilation volume and the minimum ventilation volume, in order to effectively control the ventilation volume, some enterprises use frequency conversion fans, the actual application of the control of the air volume is not accurate, production should also be based on switch control.
