A vapor-compression refrigeration cycle operates by circulating a refrigerant (such as isobutane) through repeated cycles of compression (raising boiling point), condensation (releasing latent heat to ambient air), expansion (lowering boiling point), and evaporation (absorbing latent heat from the refrigerated space), with the compressor as the only component doing mechanical work.

Evidence Quote

if you pressurize isobutane to about 80 PSI, its boiling point shoots up to 110 degrees Fahrenheit... if you feed that high pressure gas through some tubes that are exposed to ambient air, the air will cool it down to the point that it can't be a gas anymore and it will spontaneously condense into a liquid. Then, that liquid refrigerant gets sent through a restriction... in the evaporator where the pressure is very low... the boiling point of isobutane plummets to something like -20 degrees Fahrenheit... it absorbs latent heat energy which means it gets very, very cold.
