Distributors & Nozzles

The refrigerant distributor equally distributes refrigerant flow from the outlet of the Thermal Expansion Valve to each evaporator coil circuit via distributor tubes.

The pressure drop across the distributor creates the high velocity necessary to distribute the refrigerant flow evenly. The pressure drop across the nozzle focuses the flow and provides the necessary liquid, vapor mixture. The pressure drop across the distributor tubes assists in balancing the flow as it enters the distributor passages. As a result, distributor tube and nozzle sizing is critical for proper distribution.
