  • Method to recover heat from treatment premises and apparatus for achieving the method
    Patent number: 4422370
    Abstract: A method and apparatus to recover thermal energy from the exhaust air from a paint spray booth for painting of automobile chasses, whereby heat from the relatively warm exhaust air is transferred to the relatively cold supply air to the booth. The outgoing air is mixed with water or other heat-exchange liquid, and the liquid is then separated in a separation-chamber (7) adjacent the ventilation outlet (6) of the booth (5), and is circulated between the chamber and a heat exchanger (2'), through which the supply air flows.
