Abstract:
Apparatus for delivering treated cooling air for cooling molds of a glass manufacturing machine, said apparatus comprising:a manifold for distributing treated cooling air to molds of a glass manufacturing machine; a blower for delivering treated cooling air to said manifold; an indirect heat exchanger for receiving untreated cooling air and for delivering treated cooling air to said blower, said indirect heat exchanger having a coil therein, said coil having an inlet and an outlet; a water cooling tower for cooling water used in a plant for manufacturing glass articles, said water cooling tower having a first water outlet for delivering water at a first temperature and a second outlet for delivering water at a second temperature, the second temperature being higher than the first temperature; a pump for receiving water from at least one of the first outlet and the second outlet of said water cooling tower and for delivering water to said inlet of said indirect heat exchanger to flow through said coil of said indirect heat exchanger from said inlet to said outlet in indirect heat transfer relationship with untreated air flowing into said indirect heat exchanger; a temperature controlled three-way mixing valve upstream of said coil of said indirect heat exchanger for receiving water from the first water outlet and the second water outlet and for controlling the treating effect of water delivered to said inlet of said indirect heat exchanger; and a return line for returning water from said outlet of said indirect heat exchanger to said water cooling tower.
