Refrigeration Cycle Demonstration Unit

Andy Smith developed a small working refrigeration unit for Star Refrigeration Roadshow 2013. Here, Andy uses the refrigeration unit to demonstrate the principles of cooling and heating.


We’ve got here a small refrigeration unit, which will demonstrate the principles of what we do in refrigeration – either cooling or heating. The compressor is moving the heat from one side of the unit to the other.

So, what we're doing now is, by turning the compressor, we're moving heat from one side of the system to the other. As we can see by the temperature difference – which is increasing – the faster, the more work we do, the more heat we move from one side of the system to the other.
