ET 910

Advanced Modular Refrigeration System

Technical Description

A condensing unit and a refrigeration chamber with integrated evaporator and an electric heater, a power supply and a frame to mount training panels form the basic module ET 910. The condensing unit is used to increase the pressure of the used working medium and to recool it.
Panels from the available set of training panels ET 910.10 are required to form a complete refrigeration unit. The selected components are connected with the accessories included in ET 910.12. The ET 150.01 Refrigerant Charging and Evacuation Station is recommended for charging the system.

Learning Objectives / Experiments

Together with ET 910.10 and ET 910.12:
- Layout of compression type refrigeration cycles
- Evacuating and charging of refrigeration systems
- Familiarisation and functioning of components of
refrigeration systems
- Cyclic process of refrigeration
- Fault finding
- Different operation modes of the collector:
with and without collector
pump down
charging of the refrigeration circuit

Features

* Design of a variety of refrigerant circuits possible
* Clearly arranged on training panels
