Patent number: 6564864Abstract: A method of exchanging heat is disclosed. Process fluid is passed through a dry indirect contact heat exchange section while a main air stream is also passed through that section. The process fluid is passed through a second indirect contact heat exchange section while a second air stream is passed through that section. A third air stream is passed through a direct contact heat exchange section and mixed with the second air stream to define the main air stream. Evaporative liquid is selectively distributed over the second indirect contact heat exchange section and over the direct heat exchange section. The distribution of evaporative liquid over one section is independent of the distribution of evaporative liquid over the other section.Type: GrantFiled: January 12, 2001Date of Patent: May 20, 2003Assignee: Baltimore Aircoil Company, Inc.Inventors: Thomas P.

Patent number: 6213200Abstract: A system and method of exchanging heat are disclosed. Three heat exchange sections are used: a dry indirect contact heat exchange section, a second indirect contact heat exchange section that is operable in either a wet or dry mode, and a direct contact heat exchange section. The three sections are next to each other in an apparatus to reduce the overall height of the apparatus. The dry and second indirect contact heat exchange sections receive a process fluid in series or in parallel. Separate ambient air streams pass through the second indirect and direct contact heat exchange sections before mixing and entering the dry indirect contact heat exchange section. Another ambient air stream is mixed in upstream of the dry indirect contact heat exchange section when the system is operated in the dry mode. Two independent evaporative liquid distribution systems are included. One selectively distributes evaporative liquid over the second indirect contact heat exchange section.Type: GrantFiled: March 8, 1999Date of Patent: April 10, 2001Assignee: Baltimore Aircoil Company, Inc.Inventors: Thomas P. Carter, Branislav Korenic

Patent number: 6142219Abstract: A system and methods of extracting heat are disclosed. The system may be arranged as a fluid cooler or as a fluid condenser. Three heat exchange sections are provided: a dry indirect contact heat exchange section; a second indirect contact heat exchange section that is operable in either a wet or dry mode; and a direct contact heat exchange section. As a fluid cooler, a connecting flow path connects the dry indirect contact heat exchange section to the second indirect contact heat exchange section. A bypass flow path extends from the dry indirect contact heat exchange section to the process fluid outlet.Type: GrantFiled: March 8, 1999Date of Patent: November 7, 2000Assignee: Amstead Industries IncorporatedInventors: Branislav Korenic, Thomas P.

Patent number: 5724828Abstract: A heat exchange apparatus which can be used as an evaporative condenser, fluid cooler or wet-air cooler, is provided with a direct evaporative heat exchange section overlying an indirect evaporative heat exchange section. An air entry zone common to both heat exchange sections receives an air stream blown into this zone by at least one fan, thereby pressurizing the plenum such that the air stream is forced to split and enter each section while inside the apparatus. This eliminates the need for separate air entries, thus condensing the size and cost of the apparatus, while increasing heat exchange capacity. A countercurrent air flow pattern through the direct section provides a uniformly cooled evaporative liquid for use in the indirect section. The evaporative liquid flow is parallel to the air stream provided in the indirect section.Type: GrantFiled: April 21, 1995Date of Patent: March 10, 1998Assignee: Baltimore Aircoil Company, Inc.Inventor: Branislav Korenic
