Compressor vs Condenser - what's the difference?

  • #1

Main Question or Discussion Point

I read about refrigerators and often a fridge has two components:
1. compressor
2. condenser

The compressor compresses the vapor - what does it actually do? does it increase the temperature of the vapor?
The condenser condenses the vapor into liquid
and then the liquid is expanded, resulting liquid and vapor in low pressure providing coolness

If you compresses something, don't you just make it denser hence it has more pressure?
How can you compress something without making it denser?

Thank you

Yes, the compressor compresses, resulting in higher temperature and density/pressure. You got that image from wikipedia - the next image down on that page gives you detail of what happens in each process.
