SR2040 Introduction to Refrigeration Teaching Equipment Refrigerator Training Equipment

Learning Objectives / Experiments

Fundamentals of a simple refrigeration circuit

– Detect and understand the cyclic process

– Changes of state of the refrigerant

– Represent the refrigeration circuit in the process schematic

– Representation of the cyclic process in the log p-h diagram

– Estimate key figures, refrigeration capacity and heat flows

Different operating modes

– Cool air

– Generate cold water

– Heat pump (generate hot water)

Practical exercises

– Drain and fill refrigeration system

– Fault finding
