A critical temperature below which a fluid that is expanding at constant enthalpy will experience a temperature decrease, and above which will experience a temperature increase
Fluid temperature

|
satisfying the following condition: | LaTeX Math Block |
|---|
|
T_{\rm inv} \cdot \alpha_V(T_{\rm inv}) = 1 |
where
The Fluid above Inversion Temperature
| LaTeX Math Inline |
|---|
| body | --uriencoded--T > T_%7B\rm inv%7D |
|---|
|
has negative Joule–Thomson coefficient | LaTeX Math Inline |
|---|
| body | --uriencoded--\epsilon_%7BJT%7D <0 |
|---|
|
and hence will be cooling under expansion ().The Fluid below Inversion Temperature
| LaTeX Math Inline |
|---|
| body | --uriencoded--T < T_%7B\rm inv%7D |
|---|
|
has positive Joule–Thomson coefficient | LaTeX Math Inline |
|---|
| body | --uriencoded--\epsilon_%7BJT%7D >0 |

|
and hence will be warming under expansion ().See also
