History of ventilation: The world’s first large-scale mechanical ventilation system in 1854!

In 1854, a few years after ventilating the fiasco of the permanent parliament building Reid moved to the United States. Before that, he however developed and finalized a at the time a high-tech  complete ventilation system that worked in nearly 130 years, and that of many today is considered the first of its kind. In St. George’s Hall, a large exhibition hall with combined operations in Liverpool, were installed four steam engine driven by variable speed fans on each of three meters in diameter. These could support the building up to 5,000 visitors with variable air flow rate equivalent to 5 l/s per person, which is broadly in line with current recommendations. After filtration, heating/cooling and humidification even if desired, distributed air along the walls through thousands of small holes near the floor. The indoor climate was controlled and regulated continuously in every detail, which required a small army of employees.
