| contents | We study the Joule-Thomson expansion and extended thermodynamics of a modified black hole characterised by the parameters $α$, $β$, and $σ$. Analysis of the Hawking temperature, Joule-Thomson coefficient, inversion curves, and isenthalpic trajectories shows that these parameters significantly modify the heating-cooling behaviour and thermal stability of the system. The deformation parameter $α$ and control parameter $β$ shift the temperature minimum, enlarge the cooling region, and raise the inversion temperature, while $σ$ produces a weaker but consistent influence. The heat-engine analysis reveals that $α$ enhances efficiency, whereas higher $β$ and $σ$ reduce it. Overall, the results demonstrate that geometric deformation and quintessence jointly govern the unified thermodynamic structure of the black hole. |
