the diagram looks very nice but if I remember right there is no heat transverd to the cycle within the expansion valve, the state change here is only a preasure drop with the associated temperature drop.

Heat is only supplied within the evaporator (Horizontal bottom line)

Thanks, Benbehr. After reviewing the literature, you've convinced me to remove "Heat in" during throttling. I've updated the graphic. cmglee (talk) 12:40, 22 September 2015 (UTC)[reply]
