Pressure always decreases for the positive or negative of the joule Thompson effect.
For real gas:
Dt/dp>0 cooling, temperature decrease Pressure decreases
Dt /dp<0 heating, temperature increases pressure decreases.
Dt/dp = 0 -ideal gas.
For ideal gas pressure decreases but temperature has no effect or change.

Why does temperature not decrease? Please explain.

During Throttling under adiabatic conditions, the pressure energy decreases because some of the pressure energy gets lost as frictional losses thereby increase in intermolecular energy.
Hence always there will be a loss in pressure energy thereby reducing the pressure.
