Abstract
A fan for use in agriculture which has a BLDC motor which allows for varying the speed of the fan to vary the airflow rate of the fan and vary the efficiency of the fan. A ventilation system for use in a livestock confinement building to maximize a rate of growth of the livestock. A process for maximizing the growth of livestock in a livestock confinement building by controlling the airflow in the livestock confinement building.
Claims13
A method for providing a constant airflow rate through a livestock confinement building having air inlets and outlets, the method comprising the steps of:
- a) providing a ventilation system having a plurality of BLDC fans in the livestock confinement building;
- and
- b) controlling a speed of each of the fans to control an airflow rate of each fan to move outside air through the air inlets into the livestock confinement building to maintain a constant airflow rate through the livestock confinement building,
- wherein further in step (b), each of the plurality of BLDC fans is controlled without any external feedback sensors.
A process for maximizing growth of livestock in a livestock confinement building having air inlets and outlets, the process comprising the steps of:
- a) providing a ventilation system having a plurality of BLDC fans in the livestock confinement building;
- b) monitoring environmental conditions in the livestock confinement building;
- and
- c) controlling an air flow rate in the livestock confinement building to maintain predetermined environment conditions by controlling a speed of each of the fans to move outside air through the air inlets into the livestock confinement building to maintain a constant air flow rate through the livestock confinement building based upon the growth of the livestock,
- wherein further in step (c), each of the plurality of BLDC fans is controlled without any external feedback sensors.
