Define analytical pipe connections

00:01

In this lesson, we will cover what analytical pipe connections are and how to create analytical pipe connections.

00:10

In this project Water source heat pumps have been placed on the second floor and condenser water supply and return systems have been created.

00:21

The mains for these piping systems have also been run.

00:27

Currently, if I select one of the mains and scroll down in the properties palette to the mechanical flow section, you can see that the flow is zero.

00:38

In order to get the pipe to read the flow of the equipment. There needs to be a connection between the equipment and the piping.

00:47

Instead of placing physical pipe, you can place an analytical pipe connection.

00:53

This will allow the piping to see the equipment and be able to read and calculate the flow.

01:01

To place analytical pipe connections, you can first select the equipment that you want to connect to piping.

01:09

In this case, I'll select one of the water source heat pumps and then in the contextual ribbon in the create panel, click Analytical Connections.

01:21

This opens the select connectors dialogue because there are several pipe connectors on this equipment.

01:29

This dialog works a little bit differently than some of the other dialogues in Revit.

01:33

You can simply click to select and de-select the listings in the dialogue.

01:40

In this case will select the water supply in and then click Ok.

01:49

And then I'll select the condenser water supply pipe.

01:53

And what I do An analytical pipe connection is placed.

01:58

We'll do that one more time.

01:59

I'll select the water source heat pump, click Analytical Connections.

02:05

And this time we'll select water return out and click Ok.

02:09

And then select the condenser water return main pipe.

02:15

And another analytical pipe connection is placed.

02:19

Now when I select the piping and take a look at the flow,

02:24

you can see that it is now picking up the flow from the equipment and other values are also calculated.

02:33

If I switch to the Piping Systems contextual ribbon. Once again, you can see that the flow is there.

02:40

And other parameters are calculating.

02:46

Let's do this for another heat pump. And I'll show you one more thing.

02:51

When I click Analytical Connections This time I will select both the water supply in and water return out and then click. Ok.

03:01

And now when I select each pipe, an analytical connection is placed.

03:07

So you can do that. When you have only one connector that matches the system classification of one of the pipes you're connecting to.

03:17

You wouldn't want to select all four because then Revit wouldn't know which hydronic supply to connect to.

03:23

But in this case, since we have a hydronic supply and a hydronic return, we can do that and select both of them

03:29

and Revit will be able to match them up.

03:33

Once again, the analytical pipe connection allows us to make a connection to the piping without placing actual pipe components.

03:46

Lastly, you can select an analytical pipe connection,

03:50

and you can adjust any of the parameters that are available and then you can also click Edit Type and adjust the pressure drop.

03:58

If you need to adjust that as well to account for some type of connection kit or whatever else is being used to connect the equipment to the piping.

04:12

At this point, I've connected all the water source heat pumps that are on the system to the pipe mains.

04:19

And now when I take a look at the piping system, now the static pressure is calculated because everything is connected.

04:28

So in summary analytical pipe connections are a quicker way,

04:32

to get your piping systems to calculate all the parameters without having to place physical connections.
