In this article, we’ll explore 10 key tips to ensure efficient and functional piping installation in a split-type air conditioning system:
1. Use a Tube Bender
- Utilize a tube bender to prevent improper bends in the refrigerant lines.
- Ensure that bends have a wide radius to maintain proper flow and reduce pressure drops.
- Avoid sharp bends, as they can cause significant efficiency losses.
2. Minimize Pipe Bends
- Reduce the number of bends in the piping to decrease friction losses and improve refrigerant flow.
- Each additional bend increases the equivalent pipe length, which can affect system performance.
- Wherever possible, install piping in a direct path between the indoor and outdoor units.
3. Follow the Recommended Maximum Length
- Adhere to the maximum pipe length specified by the manufacturer according to the system’s capacity.
- Exceeding this length can reduce performance and lead to operational issues.
4. Adjust Refrigerant Charge for Longer Pipes
- If the pipes need to be extended, ensure the refrigerant charge is adjusted to account for the additional volume.
- Refer to an appropriate chart to determine the exact amount of refrigerant to add.
5. Ensure Smooth Directional Changes
- For transitions from vertical to horizontal piping, implement smooth directional changes with proper inclination.
- This facilitates the return of oil accompanying the refrigerant from the compressor discharge.
6. Install Oil Traps in Vertical Risers
- For systems with significant vertical pipe lengths, add oil traps to prevent oil accumulation in undesirable areas.
- Proper oil circulation protects the compressor from damage caused by insufficient lubrication.
7. Optimize Unit Placement
- Position the indoor and outdoor units as close as possible to minimize pipe separation.
- Shorter distances improve heat exchange, reduce pressure losses, and enhance system efficiency.
8. Provide Proper Pipe Support
- Install sturdy supports at regular intervals to prevent pipes from sagging or vibrating.
- Proper support protects the lines from potential damage or leaks, maintaining the system’s integrity.
9. Maintain Original Pipe Diameters
- Retain the original pipe diameters specified for the system and eliminate any unnecessary excess length.
- This reduces pressure drops and improves overall system performance.
10. Ensure Proper Insulation
- Insulate each pipe correctly and separately to prevent condensation and maintain thermal efficiency.
- Proper insulation minimizes energy losses and prevents unwanted moisture formation.
