Create piping systems with analytical connections

00:04

Creating physical piping networks has many advantages including quantification

00:09

coordination and of course being able to retrieve

00:13

and interrogate system information including flow rate,

00:16

velocity and pressure.

00:19

However,

00:19

modeling to this level can be time consuming and could be

00:22

unnecessary if your interest lies only in the system properties,

00:28

ensure the current view is set to H VAC floor plans. One mac,

00:34

the radiators shown in each of the rooms will be connected to

00:37

the existing supply and return pipes to create a heating system.

00:41

In this example,

00:43

we will add some of the radiators to the system using physical connections

00:47

and the remaining radiators using analytical connections,

00:50

reviewing the workflow and associated properties of each approach.

00:56

One radiator is already connected to the system and a review

00:60

of the mechanical flow properties in the pipe shows the corresponding values

01:07

start by using standard modeling methods to connect the float and return pipes.

01:12

For the first radiator in the system

01:14

note the connection height is at 18 inches.

01:18

In this example,

01:20

because of the layout, the connections are not too challenging,

01:23

but typically allowances have to be made for the size of the pipe,

01:27

the elevation

01:29

coordination with other pipes.

01:31

And the fittings that will be included in the arrangement,

01:35

select the heating flow pipe at the boiler and note

01:39

the values in the mechanical flow area of the properties.

01:42

Here we see values have altered with the addition of a second radiator to the system.

01:49

Analytical connections for pipe in networks provide a quick

01:53

and easy way to create the final connection to equipment

01:56

without having to consider the potential complexities of routing pipework.

02:00

But they still provide the same information as a physically connected network.

02:06

Start by selecting the heating flow pipe at the second radiator

02:11

from the ribbon, select analytical connections

02:14

and then select the second radiator in the system

02:17

and note the changing color for the radiator.

02:20

And the analytical connection displayed here as a single line,

02:25

selecting the analytical connection

02:27

displays its instance properties

02:30

and choosing edit time allows the pressure drop to be set.

02:36

The heating return pipe can be connected to

02:38

the same radiator also using analytical connections.

02:44

A review of the mechanical flow properties in the pipe shows the values have again

02:49

altered with the additional radiator which this

02:52

time has been connected using analytical connections,

02:55

select the boiler

02:57

and see the total water flow value for the system

03:01

to complete the system.

03:03

Select the heating flow pipe,

03:06

choose analytical connections from the ribbon

03:09

and pick each of the remaining radiators

03:15

once complete,

03:17

the analytical heating return connections can be made in the same way.

03:25

Analytical connections provide a quick and

03:28

efficient method for creating mechanical piping networks

03:32

can be used with the pipe sizing tools in rev.

03:35

And they provide all of the relevant engineering data

03:38

used to validate design decisions and drive change.
