Solar breakthrough drives air-con efficiency.

Operating during Stockland Wendouree Shopping Centre in Ballarat, Victoria, a complement uses concentrating solar thermal record to furnish feverishness appetite used to appetite a atmosphere conditioning system.

The Australian Renewable Energy Agency (ARENA) supposing $520,000 to support a $1.2 million project, jointly managed by CSIRO with Stockland Group and NEP Solar.

The complement addresses a high appetite expenditure of vast blurb spaces such as selling centres and hotels due to their heating and cooling appetite mandate – around 60 per cent of sum appetite use.

The closed-loop complement uses dual ‘desiccant’ wheels to mislay dampness from a air, behaving as a dehumidifier.

A high-temperature circle uses solar feverishness for metamorphosis while a low feverishness circle functions but any outmost feverishness to broach larger potency on a blurb scale.

CSIRO Energy Director Peter Mayfield is intensely gratified with a early results.

“CSIRO’s appetite investigate is pushing down costs of renewable technologies, accelerating a transition to a lower-emissions future,” Dr Mayfield said.

“We are pioneering new technologies and this plan is a world-first proof of a desiccant air-conditioning complement regulating roof mounted concentrating solar thermal collectors.”

ARENA CEO Ivor Frischknecht pronounced ARENA is happy to have partnered with CSIRO on this technology.

“It has a intensity to serve urge a potency of solar thermal appetite systems and storage to yield purify and arguable heating and cooling in blurb buildings,” Mr Frischknecht said.

“ARENA is committed to ancillary innovative projects like this and assisting to share lessons schooled among a wider RDD sector, powering Australian renewable appetite creation good into a future.”

The atmosphere conditioning complement is powered by NEP Solar’s tray collectors with feverishness stored in a thermal oil tank.

The roof space compulsory for a solar air-conditioning record can be 40 per cent reduction than a normal single-stage desiccant system.

Solar heat-driven desiccant atmosphere conditioning systems can yield steam tranquil uninformed atmosphere into a buildings and is approaching to significantly revoke HVAC electricity use for blurb buildings.

CSIRO will continue to consider and guard a record for a subsequent 12 months to settle long-term blurb operations and serve investment as partial of CSIRO’s joining to formulating a low emissions destiny for Australia.
