Create a new system classification within a family?

I was wondering if it is possible to create a new system classification within a family.

 

For example I would like to add a duct connector to my model and assign it to a fresh air system classifaction but  there is only

Supply Air, Return Air, Exhaust Air, Other Air, Fitting & Global available to choose from and I cant find where I can add a custom system.

 

Any help on this would be greatly recieved

 

Cheers

You can creat a new duct system under the families/ductsystems. right click on a system click on duplicate then click on new system you created then edit the type properties of the new system you created.

Why would you want to create a new classification in the family as you can't do that in a model??

I think you are getting confused between system classification and system type.

The classifications are core to the piping and ducting system and are a set list.

You can however have different types of system based on the core classifications.

For example - check your Fresh air duct system - it is classification Supply air. That's because no matter what type of supply air system you have it still just supplies air and doesn't exhaust, etc.

So for your AHU you just need the correct core classifications set with the right parameters then when you load into your model you can then conenct any type of supply air system to it.

Hi, thank you for you reply.

 

I have added new systems in the way you explained before while creating a project but I require the new system to be available in the family editor but i am not able to add it in the same way as in a project. I would like to add a fresh air sytem to where is shown on the image attached.  Hope the image explains a bit clearer

 

Thanks

You can't create a new system with in a family model. My previous post was confused my apologies.

Thanks for the image.

Perhaps my previous explanation was not clear. You don't need to add a duct system type to the connector other than the preset list (even though you can't anyway).

A fresh air duct system is the same as a lobby pressurisation system which is the same as a general supply air system - they are all classified as supply air and hence work in the same manner.

All you need to do is decide which connectors are supply air, whihc is a return air and which is an exhaust. Then set the flow direction, configuration etc. as required to get the information to flow in the right direction in your duct system.

When you load the family in the model, you can then duct it up using the Fresh Air duct type and hopefully you will get you flow rate to populate from the equipment to the fresh air intake louvre.

Thanks thats a great help. As you said i was getting confused between systems & there classifications but make sense now that you expained it.  

 

Thanks again for all replies. Great forum !

 

Cheers

I am having a similar problem with the plumbing families. I am using floor drains to feed into the storm drain system but there is no system classification for storm drains. I can accept (reluctantly) that all waste water can be classed as "Sanitary', but this isn't really my problem.

 

I want to set the system type to the Storm Drain type that I created under Piping Systems but I can't change this setting in either the system model nor in the family editor. The parts are set to "Other" and greyed out and unchangeable in both cases. Is there some way this can be unlocked? What am I missing?

"Other" is the connector type you should be using. This will inherit the system of anything connected to the family. No need to re-create the system types within the family itself.

Other is not the right one to use unless it matches the connectors in the families, which it probably won't. Other is generally used for gas, medical gas, compressed air, etc.
People seem to be getting too hung up on the basic system groups. Although sanitary may make you think of dirty water drainage, it is just a name used to cover drainage. Therefore it is the most suitable for rainwater drainage. It only does basic discharge unit calcs so no good for rainwater. However when scheduling the drainage systems, you will get all the types in your project in one schedule rather than using two types of schedule.
So, with regards to adding to your families - no need to worry about it as you just need to make sure that the basic system group type is applied correctly. I.e HVAC piping use Hydronic supply or return, SVP or RWP use sanitary, Vent pipes use vent, etc.
You also need to make sure that you set up the various system types with the correct basic system groups in your project & template.

Hi Friend,

                   Thank for your guide line but we know ready about this duct system creation,Actually, we want to know that system classification is inside the family.That mean for duct connector system classification.Please Look below picture.Capture.PNG

Not quite sure what you are asking but the overall thread explains the difference between system classifications and system types. Fmailies only contain system classifications and the models contain the system types based on the system classifcations.

I am making a family for a balancing valve.  On the inlet side of the valve I have "Domestic Hot Water" system classification.  I would like to make the outlet "Domestic Hot Water Return".  Are you saying there is no way to make a system classification in the family in order to do this?  This is how I made a connector element family to change piping from "Sanitary" to "Vent", which are both included as system classifications in the family.

That is what is being said. There is no need to make the system sub type in the family. That is all done when you uae the famiky in the model. You need to set the connector properties correctly based on the engineering requirements and the position of the element in relation to the system. I.e for your valve -
dhw flow typically in & preset and return typically out and preset.
Connectors aren't just for changing piping properties, they are primarily there for creating systems and secondary use for calculations.
