Project Spotlight: Tamahere Eventide Home and Retirement Village
Tasked with the HVAC design and build for this project directly, All Seasons Air Conditioning was able to start on the front foot by downloading the architectural models onto their CAD software with the Mitsubishi Electric CAD models.
Pre-planning with CAD drawings helped overcome key design challenges
Due to each plant room housing multiple hydronic branch controllers, full fresh air ducted, and water fill sets, fitting these would have been difficult without prior modelling. Plastic composite piping was required to be run down significant lengths of corridors before connecting to a bulkhead supplying each care room. This was an obstacle when the piping’s internal diameter is 20mm with 13mm of insulation. As such, fitting the flow and return, which is much larger than standard copper refrigeration, would have proved a challenge on-site without pre-design and planning.
CAD drawings allowed full visualisation of the system for easy installation
Each of the two plant rooms was located above supply cupboards servicing their own floor’s care suites and supply fresh air ducting around the facility. Up to 850m of indoor plastic, composite piping was required for each hybrid branch controller. These distances are used to calculate the expansion tank sizing per box. As a result, full-sized drawings included CAD models of the R32 HVRF outdoor units for installation arrangement and piping layout.
