Engine Testing Room for Automobiles
FFP’s – Frequently Faced Problems
Commom automobile emissions are NO, NO2, N2O4, SO2, CO, CO2 and residual hydrocarbons. Considering the health hazards that these can cause it is necessary to identify and quantify these emissions. Engine Testing Rooms are designed to cater to this segment.
However assuaging the exact figures of these emissions becomes a difficult task when external agents like temperature and humidity come into play. These hinder the operation of the sensors installed for measurement of discharges.
Under such conditions the figures observed are often not accurate.
The dew point of the chambers where the testing is done is maintained at -30ºC.
RH to be maintained
Dew point to be maintained is -30ºC.
In the present day circumstances when emissions from vehicles running on petrol and diesel are to a great extent held accountable for the spiraling global temperatures, it is imperative for correctly assuaging the amount of gaseous emissions released from automobiles.
However, the accuracy of test results is often hindered because of temperature and humidity. In order to minimize this it is necessary to control or eliminate these external factors whenever possible.
Bry-Air's recommendation is to install a Bry-Air desiccant dehumidifier as they are capable of maintaining dew point as low as -60ºC regardless of ambient conditions.
Desiccant Dehumidification in combination with Air-Conditioning provide the required humidity and temperature parameters necessary for Engine Testing Rooms. In a Desiccant System, the process airstream passes through a desiccant medium. The desiccant adsorbs moisture directly from the airstream.
