SR2040 Introduction to Refrigeration
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
