Split AC CAD Block – Free Download
A Split AC CAD block is a pre-designed AutoCAD drawing used in HVAC and MEP layouts to represent air conditioning units in architectural and mechanical drawings.
HVAC engineers and designers commonly use AC CAD blocks to speed up drafting and maintain drawing accuracy.
These CAD blocks help in:
- HVAC layout drawings
- Mechanical equipment layouts
- Ceiling plan drawings
- Air conditioning system designs
With ready-to-use AutoCAD blocks, engineers can quickly insert AC units into building drawings without creating them from scratch.
What is a CAD Block?
A CAD block is a reusable AutoCAD object that represents equipment, fixtures, or components in a drawing.
Examples include:
- HVAC equipment
- Electrical symbols
- Plumbing fixtures
- Mechanical equipment
Using CAD blocks helps engineers maintain standardized drawings and faster design workflows.
Types of Air Conditioner CAD Blocks
Different air conditioning systems require different CAD blocks.
1. Split AC CAD Block
A split AC system consists of:
- Indoor unit
- Outdoor condenser unit
These blocks are used in residential and small commercial HVAC layouts.
2. Cassette AC CAD Block
Cassette AC units are ceiling-mounted air conditioners commonly used in:
- Offices
- Shopping malls
- Commercial buildings
Cassette CAD blocks show the air diffuser pattern and installation layout.
3. Ducted AC CAD Block
Ducted systems distribute conditioned air through ducts and diffusers.
These blocks include:
- Air handling unit (AHU)
- Duct connections
- Diffusers
Split AC CAD Block Dimensions
Typical split AC indoor unit sizes:
| Capacity | Width |
|---|---|
| 1 Ton | 800–900 mm |
| 1.5 Ton | 900–1000 mm |
| 2 Ton | 1000–1100 mm |
Outdoor units are generally placed on balconies or rooftops.
How to Use AC CAD Blocks in AutoCAD
Follow these steps to insert an AC CAD block:
- Open your AutoCAD drawing
- Use the INSERT command
- Select the DWG CAD block file
- Place the block at the desired location
You can scale and rotate the block according to the layout.
