Adiabatic accumulator system

An accumulator system is regarded as adiabatic when the pressure change is fast enough that no significant heat is transferred between the outside environment and the system. Because the temperature can change in an adiabatic process due to internal system variations, the gas in the system may tend to cool down when expanding. In this connection, it would also mean that its pressure is significantly less than in an isothermal system at a given volume.
