Pressure-enthalpy diagram of a real refrigeration cycle Figure 3 shows the pressure-enthalpy diagram of a real refrigeration cycle. The key difference between the real cyclic process and the ideal cyclic process is that compression is not isentropic. Thus more work must be expended at the compressor to achieve the same final pressure.

WebConventional and magnetic refrigeration cycles use different physical effects to cool things off. When a gas is compressed (2), it heats up, but if it is cooled and then allowed to expand (3), its temperature drops much lower than it was originally (4); this principle keeps food in your home refrigerator cool.
