Technical information Refrigeration Metering device

Dispenser

Liquid, leaving the condenser enters the dispenser in basically the same state (point 4). He is now undergoing limited disclosure, which causes a pressure drop to the level of the evaporator. Pressure drops about 277.7 PSIA at the input of the metering device about 83.4 PSIA at evaporator inlet (paragraph 1). Pressure change occurs change the saturation temperature from 120F 40F. refrigerant has now become a low pressure and low temperature of the mixture of saturated liquid and vapour.

No change in enthalpy of the refrigerant as it passes through the dispenser. The distance it travels short and stream passes quickly.
