Throttling means that when the fluid passes through the shrinkage cavity or valve, the flow will be blocked, and vortex, collision or friction will occur at the shrinkage cavity. The pressure after shrinkage is much smaller than that before shrinkage. During throttling, the fluid neither does work externally nor has heat exchange, so the enthalpy value before and after throttling remains unchanged, but the pressure decreases after throttling, the distance between molecules increases, the potential energy of molecular interaction increases, and although the flow energy decreases, it generally does not change much, so the kinetic energy of some particles in the fluid must decrease, the thermal movement of molecules slows down, and the temperature naturally decreases.
