Ventilation in Agricultural Buildings: Characteristics and Measurements Methods (Review)
- Emad A. Almuhanna
- A ventilation system is used to control the physical micro-environment within a livestock and agricultural building. Information about ventilation systems in livestock and agricultural building is presented in this review, this review covers: 1) Information about air ventilation systems including contribution of the ventilation system to control micro-environment, methods for ventilation rate control, principles of modulating ventilation control, ventilation efficiency, ventilation effectiveness, ventilation for animal's houses, ventilation for greenhouses and ventilation parameters; 2) Ventilation system performance covering natural ventilation, supplemental cooling fans and tunnel ventilation; 3) Methods used to measure the ventilation rate through a ventilated space. The distinction between direct and indirect measuring methods was clarified. The following findings were obtained by this review: For continuous and accurate measurements under field conditions, the method of a free running impeller gives high accuracy. Methods based on velocity point measurements (eg. pitot tubes, hot wire anemometers, vane anemometers) require a large number of sensors and therefore considered costly methods. Pressure based methods like orifices and nozzles need expensive pressure transducers and can only operate in relatively long ventilation ducts with clean air. Indirect methods (eg. tracer gas method, Co2 -balance method) for measuring ventilation rate give only an indication of the ventilation rate over an extended period of time (e.g. several hours). Besides the problem of accuracy, the relatively high cost of a reliable gas monitors makes the tracer gas method not suitable as a continuous feed-back sensor in a ventilation rate controller.
