Air Conditioning System with Climate Chamber

Technical Description

This trainer with a complete air conditioning system provides a comprehensive range of experiments on indoor ventilation engineering. It has a conditioning chamber in the control loop. The chamber is large enough for people to stand in, so it is possible for the students to investigate the effect of various climates based on their own perception. The system components (such as radial fan, electrical heater, steam air humidifier and refrigeration set) are all commonly used in commercial air conditioning and ventilation engineering. The system is operated using a DDC control processor that also has an RS232 interface. This facilitates automatic and manual operation.

Learning Objectives / Experiments

With the system it is possible to demonstrate all operating states that characterise a complete air conditioning system:
- Heating of the chamber
- Cooling of the chamber
- Humidification of the air
- Application of the mixing line
- Investigations on human comfort

Features

* Full air conditioning system with full-size chamber for
comfort testing, suitable for a person₁
* Multiple loop control processor with PLC₁
* External access via RS232₁
* System components widely used in air conditioning
and ventilation engineering₁

* PC data acquisition possible with ET 611.20
