Australian Developments in Solar Cooling

Stephen WhiteCSIRO Energy TechnologyMarch 2011



Contents

• Technology Status

• Differentiation in Australia

• Specific Australian Developments



Australian activity

Australia in the top 10• Operational

• 3 large• 1 small

• Being commissioned• 2 large

Sparber et al, 2009, IEA Task38

• Tender• 3 large

• Not confirmed others• 3 small



Technology maturity



Developing the Australian Market

• Niche markets where “energy-only” economics are less important• Premium buildings requiring high star rating• Constrained electricity networks

• Reduce cost/ increase performance• High efficiency components• Volume production (off the shelf components)• Plug and play deployment (turn-key supply)• Plug and play deployment (turn-key supply)• Capture co-benefits/ dual function

Europian Photovoltaic Industry Association , 2005



The key components

Solar HeatCollection

Thermal Cooling Process

• Air collectors

• Flat plate collectors

• Absorption chillers• One stage• Two stage

Hot Cold

ManufacturingProduct development

• Evacuated tube collectors

• Tracking collectors

• Two stage

• Adsorption chillers

• Desiccant cooling• Solid• Liquid

• Ejectors

Noting: System integration with auxiliary equipment items (cooling towers, buffer tanks, heat exchangers etc) is very important



High efficiency roof mounted components #1Concentrating solar collectors enable higher temperatures which enables high efficiency two stage absorption chillers

PolyTrough 1200• Linear trough collectors

Invensor adsorption chillers - 9 kWSolarNext absorption chillers 12-18kW

World Energy absorption chillers – 105 – 1845 kW

Component suppliers/ system providers

Climatewell absorption chillers ~ 5 kW

Broad absorption chillers + collectors 16 to 3578 kW

Thermax absorption chillers + collectors(?) 35 and 7500 kW

Mayekawa adsorption chillers 105 to 430 kW

Shuangliang absorption chillers 350 – 6980 kW Sortech adsorption chillers 8 – 15 kW

Where too from here

• Level playing field access to Renewable industry support (credits, capital, grants etc)

• Roadmap & pro-active industry vision

• Packaged & standardised products

• Industry capacity building

• Quality assurance

This requires increased co-ordination & collaboratio n



Conclusion

• There are compelling reasons for Australia to consider solar airconditioning (compared with other countries)

• Australia has one of the most installations (and the largest interest group (ausSCIG)) of any country in the world

• Australia has a large number of companies developing unique products with strong potential

• Australia needs to at least ensure a level playing field against other renewable technologies to enable this industry to flourish

• Funding is required to co-ordinate roadmapping, standards development, capacity building and quality assurance
