Control Your Environment With Robust VRF System Design Services
Variable Refrigerant Flow System Design
Neville Engineering utilizes variable refrigerant flow (VRF) systems to provide precise temperature control with maximum energy efficiency. The core of a VRF system is the outdoor condenser unit. It contains a variable-speed compressor that modulates capacity to match cooling or heating needs. This condenser connects via refrigerant piping to multiple indoor fan coil units. The component enables different zones to be served by the same system.
Our state-of-the-art control system coordinates communication between outdoor and indoor units, monitoring zone requirements and varying refrigerant flow accordingly. By continually optimizing the refrigerant circuit to zone loads, our VRF systems achieve far greater efficiency than conventional HVAC equipment. We deliver premium comfort, flexible zoning, and reduced energy use for retrofit and new construction projects.
Here’s what you experience when you introduce our VRF HVAC systems to your commercial building:
- Exceptional energy efficiency
- Individual zone temperature control
- Quiet operation
Small outdoor unit footprint - Simultaneous heating and cooling
- Integrated ventilation options
