The temperature change of the fluid (liquid or gas) before and after adiabatic throttling is known as the temperature effect of throttling. The temperature of the fluid decreases after throttling (T2 < T1), a phenomenon known as the throttling heat effect; when the temperature of the fluid remains unchanged before and after throttling (T2 = T1), it is called the throttling zero effect. The temperature effect of throttling is related to the type of fluid, its state before throttling, and the magnitude of the pressure drop before and after throttling.
