سیستم VRF

برگه‌ها

Variable Refrigerant Flow (VRF) technology represents one of the most efficient and flexible HVAC solutions available today. By varying the flow of refrigerant to multiple indoor units, VRF systems optimize energy consumption, provide precise temperature control, and enable simultaneous heating and cooling in different zones.

Clivet, a leader in HVAC innovation, offers state-of-the-art VRF systems designed for commercial, residential, and industrial applications, combining European engineering excellence with adaptability to diverse climates.

What is a VRF System?

A VRF system consists of:

  • One or more outdoor units with variable-speed compressors that adjust refrigerant flow based on demand.

  • Multiple indoor units (ducted or ductless) that receive varying amounts of refrigerant, allowing independent zone control.

  • Advanced control systems for precise temperature management and energy optimization.

How VRF Works

  1. The outdoor unit’s inverter-driven compressor modulates refrigerant flow dynamically.

  2. Refrigerant is distributed via piping to indoor units according to real-time demand in each zone.

  3. Indoor units can operate in cooling or heating modes, often simultaneously (heat recovery systems).

  4. The system’s control logic balances performance and energy use efficiently.

Types of VRF Systems

Heat Pump VRF

  • Provides either heating or cooling at any time (not both simultaneously).

  • Ideal for buildings with uniform heating or cooling demand.

Heat Recovery VRF

  • Allows simultaneous heating and cooling in different zones.

  • Transfers heat from zones requiring cooling to zones requiring heating.

  • Maximizes energy efficiency and comfort.

Advantages of VRF Systems

Feature Benefit
