–Hitachi VRF Case Study - Edgecliff, NSW
Choosing the flexibility of Hitachi Set Free Σ VRF & airCloud Pro IoT VRF remote management
In Sydney’s eastern suburbs, 179-191 New South Head Road, Edgecliff covers approximately 1650 square metres across three floors accommodating varied floor plan options, and has a 4-Star NABERS Energy Base Building rating.
The site recently went through an upgrade, with developer Anka Property Group appointing award-winning architects, Group GSA, for the design and delivery of the building renovations.
Techline Air Conditioning Services were the HVAC contractor for this renovation. The decision was made to upgrade the existing HVAC equipment to a Hitachi Set Free Σ Heat Recovery system utilising high static ducted units and Hitachi’s airCloud Pro IoT remote management VRF control system.
The overall system consisted of 285.5kW of Heat Recovery VRF, 18 high-static ducted units, 2 mid-static ducted units, and Hitachi’s airCloud Pro for remote VRF management with a Central Station Mini Centralised Controller on the switchboard.
Techline Air Conditioning Services used Hitachi VRF because it overcame the challenges presented by the upgrade.
There were limited space restrictions when it came to installing the pipework, Hitachi’s new branch boxes, which accommodate up to 16 ports, were the perfect solution as they are more compact and lighter compared to other products in the market. The compact design made it easier to find locations and position branch boxes to make the best use of limited space for installation.
