Patent number: 11859924Abstract: In one aspect, a cooling tower system is provided that includes an evaporative heat exchanger, a sensor configured to detect a parameter of evaporative liquid distributed onto the evaporative heat exchanger, and an evaporative liquid treatment system. The cooling tower system further includes a controller having a normal operating mode wherein the controller operates the evaporative liquid treatment system to treat the evaporative liquid upon a determination of inadequate evaporative liquid quality based at least in part on the parameter of the evaporative liquid. The controller has a failsafe operating mode wherein the controller changes operation of the cooling tower upon a determination that the operation of the evaporative liquid treatment system is unable to remedy the inadequate evaporative liquid quality.Type: GrantFiled: May 12, 2021Date of Patent: January 2, 2024Assignee: Baltimore Aircoil Company, Inc.Inventors: Preston Blay, Frank T.

Publication number: 20220228817Abstract: In one aspect of the present disclosure, an indirect heat exchanger pressure vessel is provided that includes an inlet header to receive a pressurized working fluid, such as water, glycol, ammonia, and/or CO2. The indirect heat exchanger pressure vessel includes an outlet header to collect the pressurized working fluid and a serpentine circuit tube connecting the inlet and outlet headers. The serpentine circuit tube permits the pressurized working fluid to flow from the inlet header to the outlet header. The serpentine circuit tube includes runs and a return bend connecting the runs. The return bend has a controlled wrinkled portion comprising alternating ridges and grooves. The alternating ridges and grooves strengthen the return bend and permit the indirect heat exchanger pressure vessel to facilitate working fluid heat transfer at a high internal operating pressure.Type: ApplicationFiled: January 14, 2022Publication date: July 21, 2022Inventors: Daniel E.

Patent number: 11092394Abstract: An indirect heat exchanger has two airflow paths and an airflow generator to draw air through the airflow paths. A fluid conduit passes through the heat exchanger such that a cooling region is positioned within each of the flow paths. A dispenser is positioned to dispense evaporative liquid on one of the cooling regions. The dispenser operates in a wet mode and a dry mode. A controller regulates airflow through the first flow path and the second flow path, and also controls the operation of the dispenser. In this way, the controller may operate the airflow paths independently such that the airflow through a flow path operating in the dry mode is greater than that of the flow path operating in the wet mode.Type: GrantFiled: March 13, 2020Date of Patent: August 17, 2021Assignee: BALTIMORE AIRCOIL COMPANY, INC.Inventors: Preston Blay, Ravindra Singh, Frank T.

Patent number: 8931158Abstract: A liner and method of application for use on a metal surface to protect metal structures such as cooling towers, evaporative condensers, and other liquid containing vessels such as tanks from corrosion, leaks, and wear. The liner is an inexpensive apparatus and process comprising a coated metal having a second sealing and bonding layer and a third protective sealing layer. The liner method comprises applying an organic bonding layer onto the galvanized substrate, and applying an elastomeric barrier coating to the bonding layer. The barrier coating material is applied to preseal the seams between adjoining panels assembled to form the basin. The barrier coating is applied to the entire inside of the basin to form a homogenous barrier coating extending out of the basin. The liner edge is isolated from the basin by extending the liner to a point between the basin and an upper section.Type: GrantFiled: January 25, 2011Date of Patent: January 13, 2015Assignee: Baltimore Aircoil Company, Inc.Inventors: Frank T.

Patent number: 6820685Abstract: A heat exchanger coil assembly is made up of arrays of substantially equally spaced apart serpentine circuits located in the coil assembly region of the conduit, with adjacent circuits being arranged in a parallel offset fashion in which adjacent return bends are overlapping. The tubes have an effective diameter of D. Depression areas are provided at the points of overlap to locally reduce the diameter at the overlap. This provides a circuit-to-circuit with a density D/S>1.0, preferably greater than 1.02, where S is the spacing between adjacent circuits and D is the effective diameter of the tubes.Type: GrantFiled: February 26, 2004Date of Patent: November 23, 2004Assignee: Baltimore Aircoil Company, Inc.Inventors: Thomas P.
