专利汇可以提供Ventilating method for cattle shed and its apparatus专利检索，专利查询，专利分析的服务。并且PURPOSE: To considerably improve the circumstances of an existing facility with a rather small amount of investment required only for providing at least two air fans, by a method wherein the air inside a cattle shed is gathered by a second air fan to send it to a first air fan, and discharged outside by the first air fan.
CONSTITUTION: Two or more air fans, e.g., first, second and third fans 12, 13 and 14, are located at the first, second and third positions in order and arranged one behind another in a line at distances which allow the air flow of a fan to reach the other fan on the down stream. And, when the fans 12-14 are operated together, the air in a cattle shed 10 flows in the direction shown by arrows F
1 , F
2 , and F
3 , that is, the air is sent in turn from fan 14 to the fan 13, from the fan 13 to the fan 12 and finally discharged outside by the fan 12. Thereby, the incoming air flow from the outside is forcibly developed and a circulating air flow is produced between the inside of the cattle shed and the outside. Therefore, the air in the cattle shed is kept clean.
