Everything I have read says to size the accumulator to contain the entire charge. I can't tell you how to size the suction line HX only that the 42mbtu unit I am making now has one about 8" long. It is a 3/4" pipe inside a 7/8" pipe, IIRC. I got some of the parts from an old westinghouse unit which was working well after 30 years but the case rotted out.
