The Engineering Process
A successful VRF implementation requires meticulous mechanical precision. Here is how we build a leak-proof, highly efficient refrigerant network.
Load Analysis & Thermal Zoning
VRF systems shine through independent control. Our engineers calculate the distinct heat loads of various rooms and divide your facility into independent thermal zones. This ensures the system can provide deep cooling in a packed conference room while running on low power in an empty cabin.
- Calculating precise room-by-room heat loads
- Defining independent temperature zones
- Sizing outdoor and indoor unit combinations
- Planning shortest route for copper layouts
Copper Piping & Brazing
The integrity of a VRF system relies entirely on its piping. Our certified technicians lay out heavy-gauge copper pipes using nitrogen-purged brazing techniques to prevent internal oxidation. The network is then meticulously wrapped in high-density nitrile rubber insulation to prevent any condensation or thermal loss.
- Hard-drawn copper piping installation
- Precision installation of Refnet (Y-Joint) branches
- Nitrogen-purged, zero-oxidation brazing
- High-grade nitrile rubber thermal insulation
Testing, Addressing & Handover
Before activation, the entire copper network undergoes rigorous pressure testing using dry nitrogen. Following a deep vacuuming process, the precise amount of refrigerant is charged. We then electronically address each indoor unit to the central controller, ensuring seamless communication across the entire VRF network.
- High-pressure nitrogen holding tests
- Deep vacuuming and moisture removal
- Electronic addressing of indoor units
- Centralized controller setup and client handover
