History of ventilation: Heated supply air in winter, cool supply air in the summer in 1810!

In 1810 in the ultramodern hospital Derbyshire General Infirmary in England  a fuel-powered ventilation system was installed that could provide the building with warm air in winter and cool air in summer. Ventilation towers were provided with wind pledged “dancer” for increased driving force. The supply air is taken in through the 70 m long tunnel whose temperature was relatively constant year round, but in winter could air even after preheated in furnaces on each floor when necessary. It may be added that the hospital’s ventilation system was not the only cutting edge of technology installed. Also there were installed automatic water toilets, adjustable beds with foot warmers, washing machines and a transport system where wet laundry was driven to the drying room with drying racks on rails.
