after doing some research for refrigeration equipement the higher the evap temp drop is the more humidity its capable of removing! not sure if that's true. I think of it this way. the higher the temp drop the faster it will cool in turn running less and removing less humidity from the air. if I picture a basic ac system that's running with a 15 degree split will need to run longer than a unit operating with a 20 degree split to satisfy the thermostat setpoint, in turn removing more humidity. maybe for ac its backwards one guy told me I cant compare it to an ac system. anyways im trying to grasp it better on the refrigeration side of things if it makes a difference.
