Abstract:
1. A heating tower apparatus for heating a liquid having a vertical axis, comprising: a top wall having an air flow inlet disposed thereon that provides an inlet air flow stream; a base portion that opposes said top wall, wherein said top wall and said base portion extend generally parallel to one another; a heat exchange portion comprising coils through which a liquid to be heated flows; a first side wall that extends between said top wall and said base portion, wherein a first air flow outlet is disposed on said first side wall which first air flow outlet extends the entire distance between said heat exchange portion and said base portion and provides a first outlet air flow stream, wherein said first air flow outlet has a first outlet door that extends the entire length of the first air flow outlet between said heat exchange portion and said base portion wherein said first air flow outlet door moves between an open position and a closed position; a second side wall that opposes said first side wall, wherein said second side wall extends between said base portion and said top wall, generally parallel to said first side wall, wherein a second air flow outlet is disposed on said second side wall which second air flow outlet extends the entire distance between said heat exchange portion and said base portion and said second air flow outlet has a second outlet door that extends the entire length of the second air flow outlet between said heat exchange portion and said base portion wherein said second air flow outlet door moves between an open position and a closed position and wherein said first air flow outlet directly opposes said second air flow outlet, wherein the heating tower is operable in a first configuration in which said first outlet door is in the open position and said second outlet door is in the closed position, and wherein the heating tower is operable in a second configuration in which said first outlet door is in the closed position and said second outlet door is in the open position, and wherein the heating tower can be switched between the first configuration and the second configuration.
