6-Point VRV System Engineering Protocol
1
Daikin Service Checker Software Connection
Reading real-time operating parameters across all connected indoor address nodes.
2
Dry Nitrogen Pressure Holding Test
Testing multi-branch Refnet piping networks at 450 PSI for 24 hours prior to gas charging.
3
Inverter PCB Heat Sink & Fan Audit
Clearing dust from main inverter power modules to prevent thermal safety shut-offs.
4
Individual Zone Thermal Delta Audit
Measuring return air vs discharge air temperatures across all indoor cassette and ductable units.
5
Drainage Lift Pump & Condensate Decontamination
Flushing internal lift pump lines on ceiling cassettes to eliminate bio-slime build-up.
6
Commissioning Sign-Off & 90-Day Warranty
Handing over diagnostic printouts and issuing official 90-day service warranty documentation.
Each indoor unit in a VRV system contains its own Electronic Expansion Valve (EEV) connected to a central communication network. When a specific room requests cooling, its EEV opens incrementally to allow exact refrigerant mass flow while unused rooms close their valves.
Yes, 3-pipe VRV Heat Recovery systems can transfer waste heat rejected from cooled rooms to provide hot water or space heating in other areas, making them ideal for hotels and luxury residences.
