Installation and Data Acquisition Study to Test Circuit Solver TRV DevicesAbstractA Circuit Solver Thermostatic Recirculation Valve (TRV) manufactured by Therm-Omega-Techcompany is a self-actuating thermostatic recirculation valve which automatically andcontinuously maintains the end of each domestic hot water supply line at the specified watertemperature. This simple inline valve completely eliminates the need for time consuming andexpensive manual balancing procedures and equipment. By allowing only water that actuallycools below the set-point to flow to the return, a circuit solver also eliminates the need foroversized recirculation pumps which cause pipeline erosion and waste energy.Therm-Omega-Tech is a major supporter for Sam Houston State University (SHSU) whose goalis to extend academic studies for future engineering technology students. A group of engineeringtechnology students have been challenged for a multi-year instrumentation project. The studystarted in May 2012 and still continues to challenge young minds after multiple phases of theproject have been completed. Students were given multiple tasks to install circuit solver TRVvalves in university dorms to test the valves. The first task was to work with an engineering firmto learn the required design work. After approval of the design work, students worked withplumbers to install circuit solver-TRV valves to university dorms. Following installation, dataacquisition devices were identified and purchased to determine the temperature of the water atseveral locations (bathtub, restroom, and kitchen) in the dorms. Wireless transceivers are used toreport this data to a main server computer for further data-mining. All the collected data analyzedand findings are reported to Therm-Omega-Tech for future investigation. Presently, students arechallenged to test the valves for any corrosion due to water. Students are now working with aplumber once more, this time to remove some of the valves for corrosion testing. All the phasesof the project and student involvement will be reported in the paper.
