The Mechanization of Transport in Vinyl House (III)

Concentration of CO Gas of Atmosphere in Vinyl House by Exhaust Gas of Gasoline Engine

Abstract

Assuming that a gasoling engine was mounted on the cart which was used in a vinyl house, the concentration of CO gas in the air was measured in the vinyl house while an engine was operating. It was to know whether a gasoline engine could be used or not in a vinyl house, because of the CO concentration in the air.
(1) The average concentration of CO in the air increased linearly with the operation time of the engine, when the vinyl house was not ventilated.
(2) When the vinyl house was ventilated by fans and ducts, the average concentration of CO in the air was nearly constant regardless of ope-ration time. The value was lower considerably.
(3) In the vinyl house whose floor area is more than about 1000m², the average concentration of CO may be less than an allowable limit when the vinyl house is equipped with a ventilation arrangement.
(4) To keep the concentration of CO around the engine less than the allowable limit may be difficult even though the ventilation is forced through the vinyl house.
(5) It is not desirable to use a gasoline engine in a vinyl house. However, when circumstances require it, the suitable ventilation should be provided so that it meets the specification of the engine and the concentration of CO in the exhaust gas. And the cart mounting engine should be used only to carry product out of a vinyl house.
