Features

Easy Installation

Compact and lightweight outside unit

Weight of 149 kg and height of 1,000 mm make installation possible in buildings with limited space, or where no space is available for outside un

Stacked-configuration

Stacked-configuration in indoor installation is possible.

Enhanced Usability

  • A variety of functions that realizes easy installation and improve reliability: Pump interlock, DIII-NET employment, Auto address setting
  • Centralized interlocking function
  • 2 types of BS units for heat recovery can improve design flexibility.

Design flexibility and Simplified installation

  • Enhanced design flexibility: uses water as heat source, therefore optimal for large buildings, including tall, multi-story buildings, the system can tolerate water pressure of up to 1.96 Mpa.
  • Long refrigerant piping length:
    • Actual piping length: 120 m
    • Total piping length: 300 m
    • Equivalent piping length: 140 m
    • Level difference between theVRV WIII and indoor units: 50 m

Design Flexibility

2-stage heat recovery operation substantially improves energy efficiency and makes the system the ideal solution to the requirements of modern office buildings, where some areas may require cooling even in winter, depending on solar heat gain received and the number of people in the room.
