@@ncengineeringtechnology3376 could you clarify what type of connections used for different sizes of CHW pipes? like threaded pipe for upto what dia? flange for upto what dia?, similarly for welded?
@@AnandKumar-yt9ml up to 2" threaded, 21/2" to 10" grooved coupling joint 12" & above welded joints, Flange are used with HVAC equipment/accessories having Flange connections. It is the normal practice for chilled water piping for standard projects, You can use any type of joint but condition is it must withstand with pressure inside the CHW piping.
@@reliableengineeringsolutio8890: i think he is asking why temperature difference is 10 F and not 15 F or else. Is that always the case for chilled water coils regardless of capacity?
Normally chilled water system is designed with temperature differences 10 F, as the temperature difference increases required chilled water flow decreases. As per standard practice followed by manufacturer,temperature difference up to 16 F can be selected, if required.
