Thermoelectric Module Testing
SEL’s thermoelectric generator work has focused on developing models at the module and system level, experimentally validating the models, and developing design tools utilizing the models for future power generation applications. SEL has a fully instrumented thermoelectric module test stand for characterizing individual modules up to 12cm x 12cm with temperature control on cold side of 10-80°C and hot side of 30-450°C with up to 800 W of heating. Temperatures, voltage, current, and heat fluxes can be logged.
Waste Heat Recovery Testing
SEL also has a waste heat exhaust rig for system testing with extensive data acquisition capabilities. The rig can provide up to 10 kW of heating, temperatures up to 600°C, and flow rates up to 0.05 kg/s. The test stand is ideal for testing waste heat recovery technologies including heat exchangers and thermoelectric power units. Simulated electrical load can be applied to maintain thermoelectric systems and peak power while monitoring transient and steady state system performance. The test stand allows for either water cooling or air cooling options.
Cook Stove Testing
SEL has developed a mobile cook stove test stand to conduct water boiling tests. The test stand allows for testing of a range of biomass-based stoves to determine stove efficiency quickly for optimization of stove design and comparison between different stove options. Fuel usage rate and water boiling rates are monitored using a high precision scale. Temperature and CO emission are also collected for stove characterization.
