Research on commissioning and performance tests of double cold source air conditioning units in a large airport

The double cold source air conditioning unit is an important equipment in the temperature and humidity independent control system for heat and humidity treatment of the outdoor air and maintenance of the indoor humidity. This paper takes several double cold source units of different types and equipment manufacturers in the temperature and humidity independent control system of a large airport terminal building in cold zone of China as the object, and conducts field tests and analysis of their actual operation performance. The solutions are proposed for the problems existing in equipment performance and system regulation.
