RP-185 -- Line Sizing With Refrigerants 717, 12, 22 and 502 PDF

This publication contains information for sizing R-12, R-22, R-502and R-717 refrigerant piping in single-phase flow. It is not intended to be an application standard. The user is referred to the ASHRAE HANDBOOK &Product Directory for such information. The pressure loss charts incorporate a new format developed for ease of use with minimum chance for errors. The input-output relation follows a horizontal straight line printed in grey. Thus, errors due to oblique turning points on closely spaced diagonal lines (common to many previous charts) are avoided. Additional convenience is provided in the suction and discharge line loss charts by read-out in both pressure and temperature loss.
