Key Considerations in VRV System Installation
After system design, proper installation is critical. Key steps include:
-
Correct electrical connections to assign addresses to all indoor units.
-
Professional installation of copper piping and refnet distributors.
-
Pressure testing the system with nitrogen to ensure leak-tightness.
-
Using a drying filter on the liquid line to remove moisture.
Proper selection and installation of VRV systems using specialized software ensure optimal performance, energy efficiency, and long-term reliability.
