Inside a test room there is an engine, usually and in most cases, an endothermic engine whose efficiency is approximately 0.3. This means that of the calorific value of the fuel supplied to the engine during its operation:
- A third is converted into mechanical energy aimed at the movement of the vehicle
Of the third contained in the exhaust gases:
- Half is dissipated inside the room by radiation from the incandescent surfaces of the mufflers
Analyzing the case of a dynamometer, in which the complete vehicle is placed, all the calorific value of the burnt fuel, except for the part expelled with the exhaust gases (therefore equivalent to one sixth of the total) and in the hypothesis of dynamometric brakes air-cooled eddy currents, remains in the rehearsal room in the form of heat.
Assuming therefore that we have a vehicle under test that develops (only) 147 kW at the wheel (200 hp), considering the fractions set out above, 408 kW (555 "thermal horsepower"!) are generated (and must be disposed of) in the test room.
...domestic stoves, wood-burning or pellet-burning, develop between 6 and 12 kW depending on the size!
Maintaining the environmental conditions inside an engine test room is essential both for the safety of the operators and for carrying out the measurements deriving from the tests.
Afonica, thanks to its fifteen years of experience, today makes available a range of fans (which are the same ones that carry out the air exchange in the test rooms of our design and production) capable of fulfilling the arduous task of keeping the conditions inside the test rooms, thus guaranteeing safety, correct operation, correct measurements, repeatability of the tests.
