Motor test rooms used in the automotive industry are specially designed spaces for analyzing the performance, durability, and emission values of engines. Tests conducted in these rooms are performed to examine how engines perform under different operating conditions, including polar regions and high altitude levels.
During tests conducted in motor test rooms, environmental factors must be kept under control, and humidity control is a prominent parameter among these factors. Dehumidifiers ensure that the room maintains the specified relative humidity level to provide ideal test conditions in motor test rooms, thus enabling required tests to be conducted under stable conditions.
Since humidity can affect the chemical composition of exhaust gases, maintaining a constant humidity level is essential for accurate measurement of engine emissions. Stable humidity levels ensure the repeatability and accuracy of emission tests. Automobile engines emit NO, NO2, N2O4, SO2, CO, CO2, and residual hydrocarbons. Considering the health hazards these gases can cause, the identification and measurement of emissions is of great importance.
Dehumidifiers ensure that environmental conditions remain constant throughout the test period. This ensures data consistency and reliability of the relevant tests. If industrial dehumidifiers are not used, inconsistencies may occur in sensor data positioned for measurement due to rising relative humidity levels in the indoor environment. High relative humidity can accelerate corrosion formation on sensor surfaces.
Furthermore, modern engines contain numerous electronic components. High humidity can increase the risk of short circuits in these components, while low humidity can lead to static electricity buildup. Maintaining ideal humidity levels is essential for the healthy operation of electronic components. High humidity can affect the engine's fuel-air mixture, which can reduce the accuracy of performance tests. Low humidity levels can prevent measurement instruments on engine components from taking accurate readings.
Dehumidifiers are integrated into the central HVAC system to measure the actual performance of engines within the target temperature and humidity range in test rooms. A signaling system must be established between the central automation of the test room and the dehumidifier.
