ABSTRACT:
A heat exchanger evaluation system (84) includes a refrigeration subsystem (126) and a platform (94) in communication with the subsystem (126) for attachment of a heat exchanger (32). The system, (84) further includes a thermal imaging camera (168) and a monitor (100). A method (180) entails routing a fluid (38) through the heat exchanger (32) via the refrigeration subsystem (126). The camera (168) detects the temperature variation across the heat exchanger (32) as the fluid (38) flows through the heat exchanger, and provides successive thermal images representing the temperature variation responsive to the flow of the fluid (38). The thermal images are utilized to determine an efficacy of the flow through the heat exchanger (32). In particular, a determination can be made as to whether the flow deviates from a pre-determined flow path (79) of the fluid (38) through the heat exchanger.
