Harrison's first mechanical ice-making machine began operation in 1851[5] on the banks of the Barwon River at Rocky Point in Geelong.[3] His first commercial ice-making machine followed in 1854, and his patent for an ether vapor-compression refrigeration system was granted in 1855. This novel system used a compressor to force the refrigeration gas to pass through a condenser, where it cooled down and liquefied. The liquefied gas then circulated through the refrigeration coils and vaporised again, cooling down the surrounding system. The machine employed a 5 m (16 ft.) flywheel and produced 3,000 kilograms (6,600 lb) of ice per day. In 1856 Harrison went to London where he patented both his process (747 of 1856) and his apparatus (2362 of 1857).[3]
Also in 1856, James Harrison, was commissioned by a brewery to build a machine that could cool beer. His system was almost immediately taken up by the brewing industry and was also widely used by meatpacking factories.[6]
Though Harrison had commercial success establishing a second ice company back in Sydney in 1860, he later entered the debate of how to compete against the American advantage of unrefrigerated beef sales to the United Kingdom. He wrote Fresh Meat frozen and packed as if for a voyage, so that the refrigerating process may be continued for any required period, and in 1873 prepared the sailing ship Norfolk for an experimental beef shipment to the United Kingdom. His choice of a cold room system instead of installing a refrigeration system upon the ship itself proved disastrous when the ice was consumed faster than expected. The experiment failed, ruining public confidence in refrigerated meat at that time. He returned to journalism, becoming editor of the Melbourne Age in 1867.
Harrison returned to Geelong in 1892 and died at his Point Henry home in 1893.
