MI - 126-Apr-06 SUCTION & LIQUID LINE SIZINGTYLER SPEC GUIDESUCTION & LIQUID LINE SIZING CHARTSUSING LINE SIZING CHARTSB asisThese line SIZING CHARTS are based on a SUCTION pressure drop equivalent to a 2 F change in saturationpressure and LIQUID line pressure drop of 5 psi. For R-404A Low Temperature 1 psi; for R-404A and R-22 Medium Temperature 2 psi is used. This is the maximum allowable pressure drop for the entirepiping run regardless if it is 50' or 250'. The advantage of the graphic representation of this information is to show just how close to full capacity a particular selection is. This is true for both thecondensing unit capacities on the individual specification sheets or the separate SUCTION line sizingcharts. When the SUCTION line graphs are arranged according to temperature the relationship of temperature and line SIZING become readily apparent. The lower the temperature, the larger the linerequired for the same heat FeetNotice the phrase "Equivalent Feet" (applies to meters as well).
