ET 915.06

Domestic Air Conditioner Module

Technical Description

The ET 915.06 experimental set-up is arranged on a clearly laid out board, which is mounted on the basic unit ET 915. The pipe connection between the basic unit and the additional module is via self-locking Schrader valves. Individual components of the system, in this case the compressor, fan and solenoid valves are actuated using the software included with the basic unit. The ET 915.06 represents a model of a simple air conditioning unit for room cooling. The refrigerating capacity is generated by an evaporator. A fan transports the air to be cooled through a ventilation duct. Solenoid valves allow to operate the unit with a capillary tube or an expansion valve as expansion element. Temperature sensors record the temperature before and after the evaporator. The airflow rate is determined indirectly by measuring the static and dynamic pressure.

Learning Objectives / Experiments

- Familiarisation with an air conditioning system for
room cooling and its main components
