Referring the illustrated psychrometric chart, suppose during the heating season that air passes over a heating coil, and this results in sensible heat gain with no change in moisture content. What statement represents the direction of the air conditioning process line? GS-RA-22

Accepted Answer

Option A: The air conditioning process line is horizontal with the coil outlet to the right of the coil inlet.. Sensible heating involves adding heat without changing moisture content. On a psychrometric chart, this is represented by a horizontal line moving to the right. Since the moisture content remains constant, the process line follows a constant humidity ratio line, with the outlet state to the right of the inlet.
