ET 600

Open Duct Air Conditioning Trainer

Technical Description

The system contains components that are actually used in building services engineering.

The core of the system is a refrigeration system for cooling air. Air cooler, steam humidifier, fan, primary and secondary heater are arranged in a ventilation duct where the air is conditioned. Electronic sensors measure values such as temperature and humidity after each stage and pressures and temperatures in the refrigeration circuit. The data can be displayed and further processed on a PC with the supplied data acquisition card and software.

A three-phase mains connection is required for operation.
