SL-Cell Intake Air Conditioning
Basic Performance
SL-CEIL Series VFC precise air conditioner is specially designed
for engine intake air conditioning engine test cell. The patent
technology and products are used, with the temperature control
accuracy of ±0.5℃, humidity control accuracy of ±3%RH and pressure
control accuracy of ±0.1kPa.
Control Principles
- Pressure:Pressure is controlled by frequency conversion of the
blower. The intake air conditions can be preset with usual setting
of air flow rate at 20-30%. By using complete follow-up device to
control the pressure, the control accuracy can be higher
(<0.05kPa), faster in response time, than without it. It is with
no lag, and suitable for the transcient control of intake air
pressure in the engine ETC test.
- Temperature:Controlled by an air heater which is either direct
electrical heating or indirect electrical heating controlled by PWM
or electric pulse control.
- Humidity:Humidified by wet film and controlled by dew point control
method.

Parameter Description
| No. | Item | Description |
| 1 | Section of Flow | The parameter selection of the intake air conditioner is based on
the max. flow of the tested engine on the testbed, which is about
5-7 times of the engine power for the reciprocating piston engine,
the upper boundary for diesel, the lower boundary for gasoline.
|
| 2 | Section of Pressure | The pressure regulating range is usually set according to standard
intake air condition normally 100kPa. Lower pressure is set only
for plateau simulating, and some other tests, for example, in 3000m
plateau, the atmospheric pressure may be 70kPa.
|
| 3 | Section of temperature and relative humidity | Temperature and R. humidity are correlated and have relatively
large influence with each other. They can be selected according to
test standards, e.g. 25℃,50%.
