Poor Distribution Through Evaporator Circuits

Probable Cause:

Incorrect size of distributor and/or orifice.

Liquid short-circuits thru unequally loaded passes and throttles the valve before all passes receive sufficient refrigerant.



Distributor tubes must be of equal dimension and length.

Liquid traps should be avoided when mounting the distributor tubes.


NOTE: at proper load there should be no more than SOF difference between any two circuits as they enter the header.
