- Cooling cycles are used for ECS.An ECS systems have 4 main equipments which are expansion valve, evaporator, compressor and condenser. All of these equipments constitute the system. The system performance limit is defined according to the equipment performance limits. Each equipment is tested sperately to define limitations of them. The performance of each equipment that makes up the system is tested separately. System performance limitations are determined at the end of the equipment level test.
- Under the guidence of stadards Equipment Level Test are conducted to ensure that the equipment in question meets its design and eligible for system integration. With ETS, testers aim to single out equipments that can cause errors and unsatisfactory performance.
- TASECS tests to what extent the equipment to be used on the basis of the system meets the requirements.
