ET 350 Vapour Compression Refrigeration Cycle Show data sheet (pdf file) Print page
Technical Description
A simple refrigeration circuit is demonstrated with this clearly laid out benchtop unit. The evaporation and condensation processes are easily observed through the glass components. The function of the expansion valve (in the form of a float valve) can be seen. The changes in the refrigerant state can also be followed by measuring pressures and temperatures. A special environmentally friendly refrigerant is used at low pressure.  
Learning Objectives / Experiments
- Evaporation and condensation
- Cyclic process on the p-h state diagram
- Calculation of the heat transfer rate at evaporator
  and condenser
- Determination of efficiency and coefficient of
  performance
Features
* Wide range of experiments in refrigeration
