ABD SS6 - Hydraulic calculations

Tomasz Magiera — Wed, 09 Nov 2016 09:21:53 GMT

Hello,

I have an issue with hydraulic calculation which are made for ventilation installation.

What I need is to calculate a pressure loss on a ductwork to fit a correct fan or ahu. For those who are not a sanitary engineers i explain that for that calculation I have to total linear loss which depands on duct's roughness and lenght and local losses which are couses by changing duct direcion, dimensions etc.

ABD has a tool called Duct System Sizing Dialogs but what I find is that it calculate only a linear losses and not even for duct's size which I drawn in a model but for duct's size which is set on settings>limit duct velocity. And here my question:

- can ABD callculate also local losses causes by elbows, transitions etc?

- can I set Duct System Sizing tool to make a calculation for a duct's size which I drawn on a model?

- can I export that calculation to an exel file?

It seems that without program's abilty to make that simple calculations I will have to find out another program to make it. Does anyone know a program which is working with aecosim and can make those calculations?

HVAC library for aecosim

Hello

We are starting using a mechanical part in our office and we have found a few problems with HVAC cells because some of them looks quite different than in a real life f.g. round dampers, some equipment etc. and it takes a lot of time to modify them. Does anybody know a hvac/plumbing manufacturer who have a library for aecosim? I haven't found any on internet.

I am using SS6

ABD SS6; Problems with device hookup tool

Tomasz Magiera — Thu, 03 Nov 2016 14:14:48 GMT

Hello

I have found a problem with device hookup tool during creating a ventilation model. When I want to connect (regid type connection) two ducts drawn on a different hight with 30 or 45deg elbow program is creating connections using only a 90deg elbow. I have chacked almost evey possible value in an autofitting and other options and nothing works. Does anyone know what can be a reason of it?

ABD SS6 - mechanical annotations

Tomasz Magiera — Wed, 09 Nov 2016 11:13:47 GMT

Hello,

I find a problem with annotations for mechanical part and for ventillation ductwork. I have checked almost every topic on this forum but I couldn't find an aswer. What I need to have in a drawing is dimension and top of a duct. I set it in drawing rules and it appears in a form which is not acceptable for me and I want to change it (see pic). I want to change dimension from "10cm" to "100" and top from "0m-5.0cm" to "TOB=0,50". Does anyone know how I can do it?

Another issue is how program knows "top of duct" value?Is there any path or file which is accountable for this. When I modify ducts there is no such information in a data. I can check it in a model only by measuring distance from top of duct and level set in floor master. Of course I can use duct offset and check this value but I have also found that even when I draw without it program "knows" a top of duct value

And the last issue is that I don't know how to change annotation type when I use "Add/Move HVAC label" tool. I want it to show me a top of a duct but now it shows me only a dimensions. Where I can change it?
