Refrigeration System Onboard of M.V. SEAFDEC 2


The history of artificial refrigeration began when Scottish professor William Cullen designed a small refrigerating machine in 1755. Cullen used a pump to create a partial vacuum over a container of diethyl ether, which then boiled, absorbing heat from the surrounding air. The experiment even created a small amount of ice but had no practical application at that time.

In 1758, Benjamin Franklin and John Hadley, both are professors of Chemistry, confirmed that the evaporation of highly volatile liquids, such as alcohol and ether, could be used to drive down the temperature of an object past the freezing point of water.

In 1805, American inventor Oliver Evans described a closed vapor-compression refrigeration cycle for the production of ice by ether under vacuum.

In 1820, the English scientist Michael Faraday liquefied ammonia and other gases by using high pressures and low temperatures, and in 1834, an American expatriate to Great Britain, Jacob Perkins, built the first working vapor-compression refrigeration system in the world.

Nowadays all over the world, every family had the refrigerator for used in routines like preparation of a cool beverage, and storage of fresh vegetables and meat for daily consumption. The refrigerating machine onboard of M.V. SEAFDEC 2 which is high speed multi-cylinder and open type. This machine is operated automatically by using thermostat in each part such as fish hold, freezing room and provision storage.
