ACS Climatic Dyno Chambers

Climatic & Thermostatic, Environmental Chambers

Product Overview

Climatic chambers coupled with rolling road dynamometers are manufactured by ACS in partnership with companies that are leaders in the technology of chassis dynamometers. This kind of climatic chambers allows testing of the efficiency of the engine compartment under climatic stress during typical cycles of a vehicle’s working life according to international automotive standards. If an appropriate gas collection and analysis system is installed, the equipment can be used to perform emission tests according to standardized worldwide guidelines.

Dry air is blown into the chamber for the engine combustion. An air pressure regulation system provides the pressure balance of the exhaust gas in order to ensure the correct working of the engine. A wind simulation system following international standards for emission tests can be installed by ACS. Also a Sun Simulation system can be installed should combined tests have to be performed.

Technical Specifications
The thermo climatic chamber responds to the typical characteristics of equipment suitable for automotive testing (as defined in Directive 70/156/EEC with a reference mass not exceeding 2610 kg); it guarantees cooling gradients consistent with the need for rapid changes in temperature and maintenance of the set point for testing at low temperatures; at the same time it guarantees the environmental conditions, in terms of temperature and humidity, according to Directive 70/220/EEC and subsequent amendments. The chamber is suitable to be used for regulated emission tests.
Key Features
Example of a chamber built according to customer specifications.
- Temperature range: -35°C/+40°C
- Rate of temperature change (average value, with and without thermal load):
  
  0.2K/min during heating from -35°C to +40°C.
  
  0.2K/min during cooling from +40°C to –35°C.
  
  0.5K/min during heating from -20°C to +40°C.
  
  00.5K/min during cooling from +40°C to –20°C.
- Nominal inertial thermal load: 2 cars weighing about 1800 kg
- 4×4 roller bench with a mass of about 15,000 kg. It is partially considered as an inertial thermal load
- Humidity control range: 20% to 95% R.H. (max R.H. at 40°C: 60%)
