VRF / VRV Systems

Variable Refrigerant Flow (VRF/VRV) systems connect multiple indoor units (wall splits, cassettes, ducted or ceiling-suspended) to one or a small number of outdoor condensing units, each modulating refrigerant flow independently to match the exact load of its zone. This makes VRF the standard choice for buildings that need many independently-controlled zones without a separate outdoor unit for every room, such as hotels, multi-tenant offices and mixed-use developments.

Key Features

Simultaneous Heating & Cooling

Heat-recovery systems can cool some zones while heating others from the same outdoor unit.

Up to 40+ Indoor Units per System

One or two outdoor condensing units can serve an entire floor or building.

Variable Refrigerant Volume

Compressors modulate precisely to real-time zone demand rather than running fixed-speed.

Centralised BMS Integration

BACnet/Modbus-compatible central controllers for building management integration.

Long Pipe Runs

Refrigerant piping runs up to 150–1000m depending on system, suited to tall or spread-out buildings.

Low Ambient Operation

Reliable heating performance in low outdoor temperatures on heat pump models.

Benefits

  • Far fewer outdoor units than one-per-room split systems: cleaner façade and roof
  • Each zone runs independently without affecting others' comfort or billing
  • Scales from a handful of rooms to hundreds of zones on one platform
  • Long-term efficiency advantage on buildings with varying zone loads

Typical Applications

  • Hotels & Hospitality
  • Multi-Tenant Offices
  • Mixed-Use Developments
  • Hospitals
  • Data Centres
  • Retail Centres
  • Educational Campuses

Available Capacities

  • 8 HP (22.4 kW)
  • 10 HP (28 kW)

  • Modular combinations for larger loads

Optional Accessories

  • Central touch-screen or web-based BMS controller
  • BC (branch selector) boxes for heat-recovery zoning
  • Refrigerant branch joints and headers
  • Energy metering per zone/tenant
  • Low-ambient outdoor unit wind baffles

Typical Installation Cost

Projects from KES 450,000

This reflects Frosten's entry point for VRF/VRV supply, installation, testing and commissioning — a full commercial system will cost more than this depending on scope. VRF/VRV projects range from small multi-split installs to large multi-building systems, so pricing is always project-specific. Cost is mainly driven by:

  • Outdoor unit capacity and count
  • Number and type of indoor units
  • Refrigerant piping and branch/refnet layout
  • Controls and zoning architecture
  • Electrical and structural requirements
  • Building type and number of floors
  • Site access
  • Commissioning and handover

Commercial VRF installations generally require a site survey and engineering assessment before we can confirm pricing. Request a free quotation and Frosten will assess your building and provide a project-specific price. See our full AC installation cost guide for a breakdown by system type.

Frequently Asked Questions

What's the difference between VRF and VRV?

VRV (Variable Refrigerant Volume) is Daikin's trademarked name for the same underlying technology that other manufacturers call VRF (Variable Refrigerant Flow). They are functionally the same system category.

How many rooms can one VRF system serve?

Depending on the outdoor unit and manufacturer, a single system can serve anywhere from a handful of rooms up to 40–60+ indoor units, with larger buildings using multiple systems.

Does VRF need a machine room?

No, outdoor condensing units are typically sited on the roof or at ground level in a ventilated plant area; no dedicated machine room is required, unlike water-cooled chiller plant.

Can heating and cooling run at the same time in different rooms?

Yes, on heat-recovery VRF systems with branch selector boxes, some zones can cool while others heat simultaneously from the same outdoor unit.
