VRV (Variable Refrigerant Volume), also referred to as VRF (Variable Refrigerant Flow), is an advanced HVAC system capable of providing either heating or cooling as needed. Its modular design allows for precise climate control with high energy efficiency.
How It Works
- A single outdoor unit connects to multiple indoor units, offering flexible zoning for different areas.
- The system adjusts compressor speed based on real-time demand, scaling from a single indoor unit up to full capacity.
- Each indoor unit has an electronic metering device, regulating refrigerant flow for optimal performance.
Key Features
- Customizable Indoor Units – Wide selection of styles (wall-mounted, ceiling cassettes, ducted, etc.) to suit any space.
- Smart Zoning Control – One master indoor unit sets the mode (heating/cooling), while slave units follow accordingly.
- Centralized Management – Easily integrates with Building Management Systems (BMS) for seamless automation.
Originally popular in commercial buildings, VRV/VRF systems are now a preferred choice for modern homes due to their compact design, energy efficiency, and adaptability to low-profile architecture.
VRV Heat Recovery: Simultaneous Heating & Cooling
Unlike standard VRV systems, a VRV Heat Recovery system can deliver heating and cooling at the same time—ideal for buildings with varying climate needs.
How It Achieves Dual Operation
- Three-Pipe Refrigerant System (liquid, discharge, suction) enables independent temperature control.
- Branch Selection Box – Directs refrigerant flow to each indoor unit, allowing some zones to heat while others cool.
- No Master Controller Needed – Each indoor unit operates independently for maximum flexibility.
This advanced setup ensures year-round comfort with minimal energy waste, making it perfect for offices, hotels, and multi-use residential spaces.
