engineering
Product Usage Instructions:
1. How VRF Systems Work:
Varix VRF Systems regulate variable refrigerant flow rates
between source and indoor units to match real-time demands. This
provides independent temperature control across multiple zones and
conserves energy by modulating overall output.
2. Components:
- Condensing Unit: A single unit can serve
multiple zones; multiple units can be connected for expanded
capacity. - Mode Selection Box (MSB): Routes refrigerant
phases to individual indoor units. - Indoor Units: Provide independent temperature
control in each area.
3. Advanced Control and Efficiency:
Varix VRF Systems optimize performance by capturing heat from
cooling zones and redirecting it where needed. This improves energy
savings and comfort simultaneously.
Key Benefits:
- Turn wasted energy into comfort
- Precise zone control and smart load matching
- AI-driven performance optimization
- Proprietary cooling technology eliminates cold drafts
- Maximizes usable space with compact design
- Fewer moving parts reduce maintenance needs
FAQ:
Q: How many zones can a single condensing unit serve?
A: A single air or water condensing unit can serve multiple
zones throughout the building. For expanded capacity, multiple
condensing units can be connected.
Q: What is the purpose of the Mode Selection Box (MSB)?
A: The MSB routes proper refrigerant phases to each individual
indoor unit, ensuring efficient operation.
Q: How do Varix systems optimize energy efficiency?
A: Varix systems featuring heat recovery capture heat from
cooling zones and redirect it where needed, improving energy
savings and comfort simultaneously.

VRF 101: HOW IT WORKS
By regulating variable refrigerant flow (VRF) rates between source and indoor units to match real-time demands, a single condensing unit provides independent temperature control across multiple zones. The system can also modulate overall output, conserving energy by scaling down from 100% capacity.
Seamlessly Deliver Zoned Comfort from a Single Source
Varix source units have a small footprint, easing installation where space is limited.

MODE SELECTION BOX
The mode selection box is key to the Varix system’s zoning and heat recovery. By routing either liquid or discharge gas to each indoor unit, it allows independent heating and cooling in each unit.
Liquid, suction and hot-gas refrigerant piping connects the mode control unit to the outdoor/source unit. The proper refrigerant phases are then routed to each individual set of indoor unit refrigerant ports, allowing each indoor unit to operate in heating or cooling mode independently.
Mode selection boxes are available in 1- to 12-port options, for connecting up to 64 indoor units to a single box.
