  In this paper, we investigate the Joule Thomson effects for AdS black holes
with a global monopole. We study the effect of the global monopole parameter
{\eta} on the inversion temperature and isenthalpic curves. The obtained result
is compared with Joule Thomson expansion of van der Waals fluid and the
equivalence were noted. Phase transition occuring in the extended phase space
of this black hole is analogous to van der Waals gas. Our study shows that
global monopole parameter {\eta} plays a very important role in Joule Thomson
expansion.
