Inventor of air conditioning and founder of the Sirocco Engineering Works in Belfast Sir Samuel Cleland Davidson , KBE (18 November 1846 – 18 August 1921) was a British inventor and engineer. Through his career in the tea import business he invented and patented a number of industrial machines and developed the earliest air conditioning systems.
The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER), which is defined by the Air Conditioning, Heating and Refrigeration Institute in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment. [61]
Margaret Ingels was born on 25 October 1892. She attended school in her home town of Paris, Kentucky and was fascinated by scientific and engineering subjects, her interest having been sparked at a young age when she noticed moisture collecting on cold glass and learned about condensation.
