Dynamometer climatisation

in dynamometer rooms

To control the temperature in dynamometer rooms LEW Automotive individually designs appropriate concepts depending on the building construction. Based on our experience we also can use nearly modular design according to the performance requirements. The units can operate in circulation air mode or in outdoor air mode according to weather and outdoor air conditions. The arrangement of the equipment normally takes place in a control room above the test bench. If the test bench height is sufficient and there are unfavorable space conditions in the control room, the system can be installed directly below the ceiling.
The design and dimensioning is realized based on the air temperature and humidity specifications of the customer. The intake air is sucked and led to the ventilation appliances via an external air ventilation grille in the front or an outdoor air intake bend above the roof. If necessary, the air in the mixing chamber is mixed with the outlet air / room air (energy-saving setting) and led to the room by a filter, cooling coil and a fan. The air distribution is realized by for example pipes of galvanized steel plate, grilles, louver dampers and injection nozzles.
The air outlet is realized by an exhaust gas fan which is located in the control room or below the ceiling as previously described. This fan sucks the air through a ventilation grille and a canal system and pushes it through protective gratings in the front and deflector hoods on the roof to the outside.

It is important to clear the exact requirements with the customer in advance to avoid an oversizing of the installation and higher operating costs.
