commissioning DX air cooled
hi guys, quick question, when commissioning a DX system (TEV) with evap in air handling unit, what load isit best to use?
ie, the air handler can either blow full fresh air over the coil or it can exchange some heat with the internal air?
on a summers day it may be 28'C ambiant external which would be alot of load on the evap, isit best to start with full fresh air when commissioning to allow for worst case load situations.

Just try and acheive the design conditions for the coil, that's all you can do really.

Use the force Luke
If not have you got pre-heat or use re-heat on recirc you can use to supplement the load?
As Brian says you just got to try get as close to the coil spec as poss.Quidvis Recte Factum Quamvis Humile Praeclarum.
