Experimental thermoelectric heat pump units, heat pumps laboratory equipment

Experimental thermoelectric heat pump units, heat pumps laboratory equipment Equipment: 1, the device is a refrigeration / heat pump experimental device using a semiconductor material produced by the thermoelectric effect. 2, the device via the DC converter, both ends of the external power supply load thermoelectric modules (nickel-chromium alloy element), measured at both ends of the module surface temperature changes, thus verifying the Peltier effect. 3, to provide a low-voltage electric heater by high temperature heat source to heat one end of the thermoelectric modules, while a small series light bulb as a load, verify the Seebeck effect and Thomson effect in the system loop while researching thermoelectric modules in a stable load power generation capacity. Experiment: 1. Thermoelectric cooling module, the temperature of hot surfaces with changes in voltage (Peltier effect Peltier Effect). 2. The open circuit voltage Thermoelectric modules with cold, changes in temperature difference between the hot surface (the Seebeck effect Seeback Effect). 3. Thermoelectric module heat transfer effect (Thomson effect Thomson Effect) when the voltage polarity exchange demo adiabatic throttling process. 4. Survey thermoelectric modules under steady load conditions, changes in the power generation performance and surface temperature difference. 5. Equipment as a refrigerator used to assess their cooling efficiency.
