Pipe design methodologies…

Fluid piping systems Generally two types of fluid piping systems are considered: once-through and recirculating systems. The once-through system uses fluid once in the equipment and then discharges it. (This system has been used less in recent years due to environmental considerations.) The recirculating system recycles the liquid in an ongoing circuit through the piping.

There are two options within the recirculating system: the open system and the closed system. In the open system design, the fluid flows into a reservoir that’s open to the atmosphere. In a closed system design, the designated fluid isn’t open to the atmosphere at any point. Trane Pipe Designer can model both open and closed systems.

A variety of considerations such as pipe costs, pressure drops, noise levels, erosion levels, and energy costs can affect established minimum and maximum velocities for the system. Friction loss is dependent on four factors:

■ interior surface roughness

■ pipe diameter

2–1CDS-PRM005-EN • Trane Pipe Designer Getting Started Getting Started

■ pipe length

■ fluid velocity

As you lay out your system, keep these points in mind to create the most cost and energy efficient design.

Trane Pipe Designer terminology…

Let’s review some terminology before we begin. Remember, the program allows you to model each leg of piping in any order as long as all the nodes are entered correctly. You may want to visit Trane Pipe Designer’s online Help to review the Modeling rules for piping systems used when defining pipe systems.

The critical flow path is the flow path that incurs the greatest overall pressure loss in the system. Increasing the diameter of pipes in the flow path can reduce the total system pressure drop. This can be accomplished by lowering the maximum fluid velocity or the maximum pressure drop per 100 feet or by manually adjusting the pipe diameter entry.

A node is defined as any point in the system where there is a change in flow (for example, with the addition of tees). Trane Pipe Designer can lay out a system that includes up to 999 nodes.

Legs are any continuous section of pipes that carry the same volume of fluid. A leg is the section of pipe that falls between two nodes. Pipe sections in a given leg are the same diameter.

Specific gravity for a fluid is the ratio of its weight to the weight of an equal volume of water at standard conditions. Viscosity is the amount of resistance a fluid offers to shear forces. The program calculates both specific gravity and viscosity for the value of water, ethylene glycol, propylene glycol, and calcium chloride solutions. You can model other fluids with the program by manually adding specific gravity and viscosity data.

For more information about the terminology used in this manual or in the program itself, refer to the online Help or contact the C.D.S. Support Center.

Layout

Trane Pipe Designer’s main screen is shown below.

Figure 2-1 Trane Pipe Designer work area

Menus and toolbar

Menus across the top of the main window organize the commands that help you manage and work with your analysis projects. A toolbar directly below the menus provides one-click access to the most commonly used commands, as well as shortcut buttons for the three applications. For more information about specific commands, refer to online Help.

*menu bar*toolbar

project tabs

worksheet tabs

*See online Help to learn more about specific menu commands, toolbar buttons, or other elements in the work area


Design Conditions tab

After clicking New under the File menu, you will see the main screen of the program with the Design Conditions tab in the foreground. You will use this screen to define the design constraints for your system, such as pipe material, absolute roughness, total pressure drop, and whether the system is an open or closed loop. You’ll also describe the fluid characteristics, type, temperature, and concentration on this tab.

If you select Other for the fluid Type, you must enter viscosity and specific gravity values for the fluid used in the system you’re modeling.


Piping Systems tab

The Piping System tab walks you through the details of your piping system. You’ll define pipe lengths, coil locations, and valve and fitting counts. You will also determine any additional pressure-reducing devices that may be present in your system. The program determines appropriate pipe sizes for distributing fluid throughout a system based on your project specific data.

The first stage in this process is to visualize the system you are trying to model. Before you enter information about your system into the program, simplify the process with these four preliminary steps.

1 Study the building plans and perform load calculations to determine coil sizes and pressure drops.

2 Sketch out the piping network, starting with the system pump. Determine the location of elbows, junctions, coils, fittings, and valves, and establish pipe lengths.

3 Number the nodes in your piping system. Remember, a node is any point in the system with a change in flow (for example, tees).


4 Determine the required flow rates in each leg of the system. A leg is any continuous section of pipe that carries the same volume of fluid. The system nodes separate the legs.

System input Define the piping network by entering the legs that comprise the system. You also need to determine the fluid flow rates in your system. Use one of the following methods to establish these flow rates.

■ The first method determines a flow rate for each leg. The program allows you to enter flow rates through branches of a tee that do not equal the flow into the tee. Since the program uses the flow rates you enter, you must ensure your system is balanced. The program does not perform a mass balance with this method.

■ The second method automatically balances entering and leaving flow rates and is probably the easiest technique. You assign the flow values through the coils in the system and Trane Pipe Designer performs a mass balance to calculate the flow rates for the entire system.

■ The third method allows you to model system diversity. Define the flow through the pump and each of the coils. If the flow through the pump is less than the sum total of the flow through the coils, the program will apply a diversity factor to the entire system.

When all the pertinent data is entered for each leg, calculate the result and review the reports.


3 Tutorials

The best way to learn how to use Trane Pipe Designer is to try it yourself. These tutorials walk you through the creation of a simple piping network and a more complex system. You’ll construct a chilled-water piping system starting with the evaporator pump, following a typical layout.

The tutorials assume you have a working knowledge of your computer hardware and operating system and that you’ve successfully installed Trane Pipe Designer.

Tutorial set up...

Complete the following steps to set up your project for the tutorials.

Open a new file■ Click the New icon on the toolbar.

–or–

■ On the File menu, click New.

If you already have a file open, the program will simply open another file. The default file name will then be “Untitled2.wp.”

Save the project with the name Tutorial.

3–1CDS-PRM005-EN • Trane Pipe Designer Getting Started Tutorials

Enter project informationEntering project information is an optional task, but it can be helpful to use as a summary of the project.

1 On the Data menu, select Project Info.

2 Fill in the information as desired.

Project information is displayed on the Summary of Entries report.

Enter design conditionsThere are several factors in the analysis of a piping system that affect pipe size calculations. Some of these factors include pipe material and absolute roughness, the type of fluid flowing through the pipe, and the temperature and viscosity of that fluid.

Let’s set up the design conditions for the tutorial.

1 On the Design Conditions tab, leave the default values in the Pipe material and Absolute roughness, and Max total

pressure drop boxes. (Keep in mind that absolute roughness can be affected by the age and cleanliness of a system, and a different value may be entered if necessary.)

2 In the Type box, select Ethylene Glycol. This is a solution of ethylene glycol and water used to protect pipes from freezing.

3 In the Temperature box, type 50 deg F. This is the mean temperature of the fluid in your system.

4 In the Concentration box, type 30%.

Note: The Viscosity and Specific gravity boxes are unavailable unless the fluid type selected is Other.

This screen shot shows the entries you have made on the Design Conditions tab. You have finished entering the design conditions and are ready to begin the next step.


The tutorial project...

In this tutorial we’ll construct a typical chilled water piping system starting with the evaporator pump. We set up our design conditions earlier, so let’s enter information about the first leg of the piping network on the Piping System tab. Several rules determine how you define your system in Trane Pipe Designer. These constraints are outlined in the online help (see “Modeling rules and methods” for more information). Carefully review Figure 1 to gather the details you’ll need for the tutorial.

The first leg of this sample problem is defined as the length of pipe between Node 1 and Node 2.

1 Click the Piping System tab and click the New Leg button.

2 In the From: Node no. box, enter 1.

3 In the To: Node no. box, enter 2. This is a closed system, so the elevation is disabled.

4 In the Leg description box, enter a description for this leg such as First Leg. As you begin your projects, you decide how detailed the descriptions should be with customized information for each job.

5 Under Leg Characteristics, define the Pipe length between Node 1 and Node 2. According to the system sketch, this length is 130 feet (30 + 50 + 50).

The default Nominal diameter is AUTO; Fluid flow and Flow

coefficient default to 0.

6 Next, determine the pressure drop in this leg due to the chiller. In the Added pressure drop Other box, enter 25 ft wg.

Note: Anything that may cause a pressure drop in the leg should be included in this value. Examples of pressure reducing devices are orifice plates and nozzles. The maximum limits are based on ASHRAE standards; the program defaults to those settings. If desired, you can make adjustments on a leg-by-leg basis or for the entire system.

7 Finally, enter the quantity of valves and fittings for this leg in the corresponding boxes. The system sketch shows that one elbow and three gate valves are located in this leg of the system.

8 Save the file.


The program uses this information to calculate an equivalent length of pipe for each fitting, and factors this into the total system pressure drop.

Add the remaining legs of the systemClick New leg and repeat Steps 1 through 8, moving from node to node. Remember to save periodically.

To enter a coil leg1 In the Added pressure drop section, check the Coil check box.

2 In the unlabeled pressure drop box to the right of the Coil check box, enter the pressure drop for the coil.

3 In the Flow coeff. box (in the Leg characteristics section), enter the Cv value to describe the control valves for each coil.

Note: This value describes the pressure drop across the valve with 1 gpm flowing through it.


Calculate the fileAfter you enter all the leg information in your piping system (in this exercise there are seven), save the file, and calculate the results.

■ On the Design Conditions or Piping System tab, click Calculate.

–or–

■ On the Data menu, click Calculate.

–or–

■ Click the Calculate icon on the toolbar.

The calculation generally takes a few seconds. When the process is complete, the Print Reports selection screen displays. You have finished the first tutorial!


Advanced tutorial

Use this advanced tutorial to help understand the process when you apply Trane Pipe Designer to more complex piping systems.

1 Start a new file.

2 On the Design Conditions tab, change the fluid Temperature to 45 deg.

3 Click the Piping System tab.

It’s helpful to have a copy of the drawing available to write on or add notes. Use the extra drawing provided for modeling preparation with this tutorial. Let’s review Figure 2 and decide how to number the nodes in this system.

One method is to establish a potential “longest” run. Number the nodes, with Node 1 representing the pump discharge. Follow the main supply and consecutively number each change in flow along the way. Continue through the coil at the end of the suspected longest run. Trace the main return line (again, number changes in flow in consecutive order) until a leg ends at the pump.

Modeled in this fashion, the system is successfully closed. Any remaining paths must begin somewhere on the main supply and end somewhere on the main return. Group paths with a numbering technique that makes the entry and exit easy to follow. For example, number one main branch as “100s” and the next as “200s.”

Another numbering method uses a corresponding supply and return leg-numbering technique. Number the pump as the Node 1 and follow the main supply to the longest run coil, and back down the return to the pump. As you number, the main return numbering is reversed on the supply side with an added zero to the digit. For example, Node 2 to Node 3 on the supply side would correspond to return numbers of Node 30 to Node 20.

Note: If Node 1 is the pump and you are numbering from 1 to 2 on the supply side, the corresponding return leg would be Node 20 to 1, not 20 to 10.

This numbering technique can help find numbering errors quickly in the file, but is limited by the fact that nodes are restricted to three digits.

Let’s use the first option we discussed as we move through the tutorial.

Complete numbering the nodes on the drawing and compare them to the numbers on the second drawing. Refer to the drawing and its additional information often as you follow the design process. Let’s enter the information on the Piping System tab from top to bottom and from left to right.

1 In the From: Node no. box, enter 1 (to represent the pump).

2 In the To: Node no. box, enter 2.

3 In the Leg description box, type Pump Discharge.

4 In the Pipe length box, type 40 ft.


5 In the Other box (in the Added pressure drop section), enter the chiller loss of 25 ft. wg.

Now, let’s add a new leg.

1 Click New Leg.

2 In the To: Node no box, type 3.


4 Enter 2 for quantity of elbows as specified on the drawing.

5 Click New Leg, and continue this process through Leg 5 on the drawing.

Save the file with a new name so that the original tutorial file remains intact. Remember to save periodically!

1 Add a new leg, as you begin to model Leg 6.

2 In the To: Node no box, type 7.


4 In the Leg description box, type Coil # 3.

5 In the Fluid flow box, enter 380 gpm.

6 In the Added pressure drop section, check the Coil check box.

7 Enter the coil pressure drop as 10 ft. wg.

8 In the Other box, enter the piping package loss as 5 ft. wg.

9 Enter the quantity of gate valves as 2.

Save the file before we continue. Want to check your work on each floor before continuing? Run the file to refine it before proceeding to the second and third floors.

1 Add Leg 7, which is similar to Leg 6.

2 The Pipe length for Leg 7 is 15 ft, the Leg description is Coil

# 4.

Note: Trane Pipe Designer allows two different legs to have the same “From” and “To” nodes if each leg contains a coil.

3 Enter Legs 8 through 11 as above (check the drawing for elbow information).

4 Add Leg 12.


5 Connect Leg 12 to the pump intake. The From node is 11 and the To node is 1; enter the pipe length of 10 ft.

The piping system is now closed. All additional legs will begin somewhere on the main supply and end somewhere on the main return.

6 Continue to enter coil Legs 13, 14, and 15 in the same fashion as Legs 6 and 7.

Note: Nodes 2 and 11 allow modeling to the second floor but are not used in this tutorial to create tees. Leg 15 does not have nodes entered for the branching of the non-operating system. Add elbows to Leg 15 to approximate the losses through the tee in which all the flow is through the branch.

You can easily add or modify branches in the piping systems and check your work as you go along. When the file is completed, compare your results to Figure 3.

Frequently asked questions...

■ What if I want to use fluid that isn’t available in the Fluid

Type list? No problem! The program has the ability to calculate viscosity and specific gravity for the four fluids that are available. But, if you want to use a different fluid, simply select Other as your fluid type, and enter values for viscosity and specific gravity that reflect your actual fluid type.

■ How does the program calculate an open system?

The program actually closes your system with an imaginary pipe leg, but the leg won’t appear in the reports or affect the pressure drop calculation.

■ Can I use different values for the absolute roughness?

Yes, you can edit the absolute roughness of the pipe material to model different degrees of fouling.

■ I want to enter an existing piping system. What should I

do? As you enter existing pipe legs, just define the diameters to establish the pressure drop based on your current system. With an existing system, take into account fouling of the pipe material for the absolute roughness.

■ What if I know the size of my pump? Enter the maximum known pressure drop for your existing system, on the Total pressure drop information field on the Design conditions tab. If you are adding more pipe legs to your system, the Auto default allows the program to select the optimum pipe size while not exceeding the existing pump size.


Adjusting default pipe prices...

Trane Pipe Designer can determine how much pipe you need, and calculate an estimated cost for your system. These estimates are defined by the unit prices you enter. The unit prices can be based on material costs alone or on total installed cost. The program uses these costs to compile a bill of materials.

To revise these values to reflect customized pricing or market changes, select Data from the menu bar, and choose Adjust cost

Per Unit.

From the drop-down menu, select the pipe, valve, or fitting material you are modeling and update the fields as necessary. You can also select pipe insulation to define the cost per square foot.

■ To enter pipe unit prices, determine the piping material you want to update: Copper, PVC, or Steel.

■ Select the desired pipe diameter, and enter the unit cost for pipes, fittings, and valves in the system. Continue defining prices for each pipe size you want to update in the program.

■ To update pipe insulation pricing, select Pipe Insulation on the drop down menu and adjust the cost per square foot.

■ When your updates are complete, click OK to save and return to your project.

Note: The new prices are applied globally to the program and become the default costs for that material for all future projects, until you revise the prices.


4 Viewing and Printing Reports

The goal of Trane Pipe Designer is, of course, to determine required pipe sizes for your system, and to find the critical path in your system for sizing the pump. With the reports generated by the program, you can document your project, size your pipes, and create a bill of materials for construction. You can even estimate the cost to build this system.
