Publication number: 20160138869Abstract: A heat exchange apparatus is provided with an indirect evaporative heat exchange section. An evaporative liquid is passed downwardly onto the indirect heat exchange section. The evaporative liquid is collected in a sump and then pumped upwardly to be distributed again across the indirect heat exchange section. An improved heat exchange apparatus is provided with two indirect evaporative heat exchange sections separated by a vertical distance. A direct evaporative heat exchange section may be provided in the vertical spacing between the two indirect evaporative heat exchange sections.Type: ApplicationFiled: January 25, 2016Publication date: May 19, 2016Inventors: David Andrew Aaron, Zan Liu, Branislav Korenic, John Edward Rule, Preston P. Blay, Philip S. Hollander, Glenn David Comisac, Gregory Michael Lowman

Publication number: 20150204626Abstract: An adiabatic condenser or fluid cooler is provided. A condensing or fluid cooling coil is provided. An adiabatic pad is provided wherein water can be used to cool the ambient air before entering or impacting the condensing or fluid cooling coil. Controls are provided that can adjust or eliminate the amount of water flowing over the adiabatic pad. The adiabatic pad may also be physically moved to allow ambient air to directly impact the condensing or fluid cooling coil.Type: ApplicationFiled: January 20, 2014Publication date: July 23, 2015Applicant: Baltimore Aircoil Company, Inc.Inventors: Greg Martell, Adam Sheer, Philip Hollander, Preston Blay, David Andrew Aaron

Patent number: 9057564Abstract: A heat exchange apparatus is provided with an indirect evaporative heat exchange section and a direct evaporative heat exchange section. The indirect evaporative heat exchange section is usually located above the direct evaporative heat exchange section, and an evaporative liquid is passed downwardly onto the indirect heat exchange section. The evaporative liquid that exits the indirect evaporative heat exchange section then passes downwardly across and through the direct heat exchange section. The evaporative liquid is collected in a sump and then pumped upwardly to be distributed again across the indirect heat exchange section. The indirect heat exchange section is comprised of a plate type heat exchanger. An improved heat exchange apparatus is provided with indirect evaporative heat exchange section consisting of a plate type heat exchanger which provides more surface area per volume compared to other designs.Type: GrantFiled: December 17, 2012Date of Patent: June 16, 2015Assignee: Baltimore Aircoil Company, Inc.Inventors: Thomas Carter, Zan Liu, David Andrew Aaron, Philip Hollander

Publication number: 20140209279Abstract: A heat exchange apparatus is provided with an indirect evaporative heat exchange section. An evaporative liquid is downwardly distributed onto the indirect section to indirectly exchange sensible heat with a hot fluid stream flowing within a series of enclosed circuits which comprise the indirect evaporative heat exchange section. An ideal flow rate for such evaporative liquid is between 2.5 and 3.5 gallons per minute per square foot of top surface area of the indirect heat exchange section.Type: ApplicationFiled: December 3, 2013Publication date: July 31, 2014Applicant: Baltimore Aircoil Company, Inc.Inventors: David Andrew Aaron, Zan Liu, Philip Hollander
