AUGUST 2012

What is a heat exchange

system?

It is a heat transfer system

Heat is transferred from one fluid to another

In the case of The Rocks (closed loop) heat exchange system will

allow multiple buildings air conditioning and refrigeration plant to

transfer heat to and from Sydney Harbour

Sydney Harbour heat exchange

systems

Sydney Harbour has been utilised for heat exchange systems for

more than a century predominantly for electricity power generation

Power stations included: Ultimo (1902), Balmain (1903), Pyrmont

(1904) and White Bay (1912)

The Rocks power station constructed (1907) – never commissioned

Emergence of commercial air conditioning in the 1960’s introduced

additional smaller open seawater systems

Open sea water cooled air

conditioned buildings

Sydney Opera House – Circular Quay

AMP Building – Alfred Street – Circular Quay

Park Hyatt Hotel – Circular Quay

Museum of Contemporary Art – Circular Quay

Sydney Convention & Exhibition Centre – Darling

Harbour

Power House Museum – Darling Harbour

King Street Wharf – Darling Harbour

Star Casino – Pyrmont Bay

Workplace 6 – Pyrmont Bay

Barangaroo (under construction) – Darling

Harbour

Closed sea water cooled air

conditioned buildings

Closed loop / hydrothermal seawater systems are rare in Australia

and around the world.

Sydney sites include Balmain Water Police (200kW) and Wharf 11

Woolloomooloo (500kW)

The proposed Rocks Heat Exchange will have a capacity of (7MW)

and is likely to be the largest of its type in the world.
