@love2hvac: Frederick Mckinley Jones, the King of transport refrigeration. A self taught engineer invited the first successful transport refrigeration. Before that they used salt, Ice and brine in an effort to preserve food. Fredrick used any cylinder engine to power a robust self contained refrigeration system to handle the vibrations and was able to change transportation of foods forever.
