Breathe Easy With Energy-Efficient Air Treatment Solutions
Air Treatment Solution for Rolleston Library & Community Centre
An anchor project of Selwyn District Council’s Long-Term Plan, Te Ara Ātea is a new 2600 sq mt library and community centre in Rolleston Town Centre.
A place for learning, gathering, connecting and exploring the new $22.2 million centre was designed by Christchurch architecture firm Warren and Mahoney. Inovo Projects Ltd were the project managers and TMCo was the engineering team.
The two-story Te Ara Ātea centre features a mixed media library, performance and art exhibition space, a museum display, studio and workshop space, and a community lounge with a fireplace and cafe.
Action Taken
Project HVAC supplied central ventilation and air conditioning plants to the project and was required to ensure they were highly energy-efficient and compact enough for a limited space plant room.
The optimal solution was two Clivet thermal wheel heat recovery Air Handling Units (AHU's) each with the matching Clivet inverter compressor condensing unit.
This ensured low-cost demand-driven space ventilation, heating, air conditioning and room humidity control using the central ventilation and air conditioning plant.
- These ventilation plants are designed to recover heat from the exhaust air and to transfer the recovered heat via a thermal wheel heat recovery device. Thus saving the energy required to temper the fresh air supplied to the building.
- The total volume of the air delivered and processed by 2 Project HVAC Clivet Air Handling Units (AHUs) supplied to the Rolleston Library is above 50,000 m3/hr.
- Total heating and cooling capacity delivered to the building is above 300 kW.
- Heat recovery efficiency of the supplied AHUs is more than 80% thus ensuring that the large part of the energy required for heating of the building fresh air is recovered from the waste heat.
Results
The challenge for Project HVAC was limited plant room space and achieving superior efficiency while keeping the price per unit attractive. The Clivet built-to-order AHU with DX coils and inverter condensers proved just the ticket.
Offering superior performance and reliability without a huge outlay and operational costs. All backed up by the expertise of Clivet trained Project HVAC technical team.
