Placing Air Terminals

Transcription

1 Placing Air Terminals Before you begin The following files are needed for this Let Me Try exercise: For Imperial: For Metric: c05_office-space_tut1.rvt M_ c05_office-space_tut1.rvt To access the files from your dataset: If you haven t downloaded the dataset yet, open your course homepage. Click on the link: Click here to download the dataset for this course. Save the course dataset to the C:\ drive on your computer. Options for opening a Revit MEP project file(s): Begin by dragging it directly into the application or by using the Open command from the Application menu. Double click a Revit MEP file, but be aware that if you have more than one version of Revit MEP installed on your computer, the file will open in the last version of Revit MEP you used. Please ensure you save all your projects to your computer as directed by the Let Me Try instructions.

2 In this exercise, you will place the air terminals in the ceiling of the rooms. Also, you will create new views, modify air terminal parameters, and place air terminals into the ceiling plan. Opening a Project In this section, you will open the project. 1. Choose Open > Project from the Application Menu. On doing so, the Open dialog box is displayed. 2. In the Open dialog box, browse to C:\ Revit_MEP_2016_Essentials\Creating_a_Mechanical_System and select the c05_office-space_tut1.rvt. file. Now, choose the Open button; the selected file opens in the Revit MEP interface. Modifying the Ceiling Plan View In this section, you will modify the ceiling plan view using the View Range dialog box. 1. In the Project Browser, expand Views (Discipline) > Mechanical > HVAC > Ceiling Plans, and double-click on 1 - Ceiling Mech to make it an active view. 2. In the Properties Palette, choose the Edit button corresponding to the View Range parameter; the View Range dialog box is displayed. 3. In the Primary Range area of this dialog box, select the Associated Level (Level1) option from the Top drop-down list and then enter 8 4 (2540mm) in the Offset edit box corresponding to the Top drop-down list. 4. Enter 0 in the Offset edit box corresponding to the Cut plane drop-down list. 5. In the View Depth area of the View Range dialog box, select the Associated Level (Level 1) option from the Level drop-down list and enter 8 4 (2540mm) in the Offset edit box corresponding to the Level drop-down list. 6. Choose Apply and then OK; the specified settings will be applied to the current view and the View Range dialog box is closed. On modifying the ranges of the ceiling plan view, the various fixtures and fittings in the model will be visible.

3 Adding the Supply Air Terminal In this section, you will place the supply air terminals to the ceiling of the rooms. 1. Choose the Air Terminal tool from the HVAC panel of the Systems tab; the Modify Place Air Terminal contextual tab is displayed. 2. Choose the Load Family tool from the Mode panel of the contextual tab; the Load Family dialog box is displayed. 3. In the dialog box, browse to US Imperial > Mechanical > MEP > Air Side Components > Air Terminals folder (for Metric, browse to US Metric > Mechanical > MEP > Air Side Components > Air Terminals folder) and then select the Supply Diffuser - Hosted family from the list displayed. 4. Next, choose Open; the Load Family dialog box is closed and the selected family is loaded in the project file. 5. In the Properties Palette, select the Supply Diffuser - Hosted: Workplane-based Supply Diffuser option (for Metric M_Return Diffuser - Hosted: Worplane-based Return Diffuser) from the Type Selector drop-down list. 6. In the Placement panel of the Modify Place Air Terminal contextual tab, choose the Place on Face button. 7. In the drawing area, move the cursor toward the upper left corner of the plan into the CEO-Office area and click to place at the location, as shown in the image below. The ceiling will host the air terminal.

4 8. In the Properties Palette, enter 300 CFM (150 L/S) in the edit box corresponding to the Flow parameter. 9. Now, choose the Modify button from the Select panel, to exit the Air Terminal tool. 10. Select the added air terminal and place the cursor at the center grip of the air terminal; the center grip turns red and the Drag tooltip appears. Press the left mouse button and drag the air terminal to fit it inside the ceiling tile, as shown in the image below. 11. After placing the air terminal, release the left mouse button. 12. Next, ensure that the air terminal is selected and then choose the Copy tool from the Modify panel; a dashed box is displayed around the selected air terminal. 13. In the Options Bar, select the Multiple check box. 14. In the drawing area, place the cursor at the center of the air terminal and click when the Midpoint snap is displayed, as shown in the image below.

5 15. Move the cursor vertically down and click when the vertical dimension appears as 12 (3658mm), as shown in the image below. 16. Similarly, copy and place the other air terminals at required locations, as shown in the image below. The placement of the air terminals may not be exact.

6 17. Choose the Modify tool from the Select panel to exit the tool. Adding the Return and Exhaust Air Terminal In this section, you will add the return and exhaust air terminal to the plan. 1. Place Air Terminal contextual tab is displayed. 2. Choose the Load Family tool from the Mode panel of the contextual tab; the Load Family dialog box is displayed. 3. In the dialog box, browse to US Imperial > Mechanical > MEP > Air Side Components > Air Terminals folder (for Metric browse to US Metric > Mechanical > MEP > Air Side Components > Air Terminals folder) and then using the CTRL key, select the Exhaust Diffuser - Hosted and Supply Diffuser - Hosted families from the list displayed. 4. Choose Open; the selected families are loaded in the file and the Load Family dialog box is closed. 5. In the Properties Palette, select the Return Diffuser - Hosted: Workplane-based Return Diffuser option (for Metric, select the M_ Return Diffuser - Hosted: Workplane-based Return Diffuser option) from the Type Selector drop-down list. 6. In the Properties Palette, click in the value field corresponding to the Flow parameter and enter 300 CFM (for Metric, 150 L/S). 7. Choose the Place on Face button from the Placement panel in the Modify Place Air Terminal contextual tab. 8. Next, in the drawing area, move the cursor in the Lounge area next to the CEO-Office room and then click inside the ceiling tile, as shown in the image below.
