Energy Transfer - Solar Model No. ET-8593 Introduction The Energy Transfer-Solar box (ET-8593) can be used for demonstrating the concept of solar heating, including the greenhouse effect. Equipment Description a) Plastic Cover The clear, plastic cover snaps onto the Solar box and acts as insulator to isolate and trap air inside, reduce convection currents, and demonstrate the greenhouse effect. The cover is very transparent to visible light but not infrared light.
Model No. ET-8593 Energy Transfer - Solar Equipment Setup Note: A rod stand is required for adjusting the Solar Box to the sun’s angle. 1. Remove the thumbscrew on the aluminum plate. Place the thermistor lug underneath the center hole on the aluminum side of the plate. Insert the thumbscrew through the hole. On the black side, put the shadow indicator over the screw and tighten (See Figure 1). thumbscrew thermistor cable thermistor lug Figure 1: Thermistor position 2.
Energy Transfer - Solar Model No. ET-8593 Note: If there is no shadow on the plate, the sun’s rays are perpendicular to the plate. 7. Plug the Temperature Sensor into a PASPORT Xplorer. To take a temperature reading, click the Start button on Xplorer. (Note: The Xplorer data can later be uploaded into DataStudio and viewed in a DataStudio graph display.) OR If you are using an ohmmeter (instead of a Temperature Sensor), turn on the meter and take a resistance measurement.
Model No. ET-8593 Energy Transfer - Solar Suggested Experiments Experiment 1: Solar Heating and the Greenhouse Effect Equipment Required Energy Transfer - Solar (ET-8593) Temperature Sensor (PS-2125) or Thermistor Sensor (CI-6527A) or an Ohmmeter/Multimeter Rod Stand (ME-9355) PASPORT Xplorer (PS-2000) or laptop computer Piece of cardboard Temperature vs. Resistance Chart (See Appendix A) DataStudio Software Part I: Solar Heating 1.
Energy Transfer - Solar Model No. ET-8593 Note: Watch the angle of the sun. The angle of the sun must be 90 degrees to the box while you are collecting data. You might have to adjust the angle of the box during the run. 6. Repeat step 5 with the plastic cover off. Analysis 1. Look carefully at both curves at the start of the run. The slope (rate of heating) for the uncovered box should be larger than for the covered box. Why? 2.
Model No. ET-8593 Energy Transfer - Solar Experiment 2: Solar Constant Equipment Required Energy Transfer - Solar (ET-8593) Temperature Sensor (PS-2125) or Thermistor Sensor (CI-6527A) Rod Stand (ME-9355) PASPORT Xplorer (PS-2000) or laptop computer Piece of cardboard Measuring tape and scale DataStudio Software *Note: This is a more advanced lab. Two Temperature Sensors or one temperature sensor and a thermometer are required.
Energy Transfer - Solar Model No. ET-8593 Analysis a) Find the slope of the line tangent to the curve at outside ambient air temperature. Do not use the Slope Tool. Highlight a small section at outside ambient temperature. At ambient temperature, the heating is only being caused by the sunlight. Below the ambient temperature, the surrounding air is cooling the container. Above the ambient temperature, the surrounding air is heating the container.
Model No. ET-8593 Energy Transfer - Solar Sample Data/Results Experiment 1: Solar Heating The covered box has the final higher temperature. With the covered box, the greenhouse effect occurs. Light enters the transparent cover, but the infrared light is not re-radiated back out. The infrared light heats the plate. Also, the cover traps the hot air inside the box, isolating and insulating the air. Experiment 2: Solar Constant Note: This data was taken late in the afternoon.
