Minimum condensate drain pipe sizing chart.
Condensate drain pipe size chart. See more related questions demand is characterised as predictable high flow rates. Slope to be at least 1 8 per foot or 1 percent that is for every 12 horizontally there must be at least an 1 8 drop vertically. A rule of thumb the condensate load used to design condensate pipe lines should be twice the maximum production load. Imc 307 2 2 tells us that an a c condensate drain inside diameter should not be smaller than 3 4 and should not be smaller than the drain pan outlet diameter.
When it comes to having a condensate pipe installed there are certain restrictions in terms of size and position that must be considered. Lines consisting of two phase flow such as trap discharge lines which are selected according to the pressures either side of the trap. Three quarters of an inch is sufficient for up to 20 tons according to the imc unless the drain outlet size is larger than in ch use t able 307 2 2 for condensate pipe sizing. The minimum size for the overflow pipe is 21 5mm and needs to be made from a non metallic material for allowing a reasonable flow of water waste.
Drain lines containing no flash steam. Internal diameter and shall not decrease in size from the drain pan connection to the place of condensate disposal. Drain s 2015 imc 307 2 2 requires that an air conditioning condensate drain inside diameter should not be smaller than in ch and should not be smaller than the drain pan outlet diameter. When sizing condensate return lines in steam distribution system remember that the maximum condensate flow is achieved during plant start up when pipes and equipment are heated up.
The chart figure 14 3 5. Condensate waste and drain line size shall be not less than 3 4 in. Condensate drain piping to slope a minimum of 1 8 per every 12 horizontal attics or furred spaces. 3 4 is sufficient for up to 20 tons according to the imc unless the drain outlet size is larger than 3 4.
