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.

b)Aluminum Plate

The aluminum plate is painted a non-reflective flat black that absorbs light very well. The hot aluminum plate re-radiates in the far infrared region, and thus the heat energy is trapped under the cover.

The reverse side of the aluminum plate is not painted. The plate can be flipped inside the box to study differences in solar heating and/or cooling between the aluminum and black surfaces. The aluminum plate can be removed to measure its mass. The white, plastic knob also serves as an indicator for the sun’s angle. When the sun is perpendicular to the aluminum plate, no indicator shadow appears on the plate.

c) Solar Box

The Solar Box holds the aluminum plate and plastic cover. On the side of the box is a rod clamp for mounting the box to a rod stand. When mounted to a rod stand, the box can be adjusted to the sun’s angle.

d) Thermistor

Inside the Solar Box is a 10K thermistor for measuring temperature. The thermistor cables are not removable from the box. The thermistor contact (metal lug) is fastened in the center, on the underside of the aluminum plate. The side jacks on the Solar Box allow you to connect a Temperature Sensor or ohmmeter to the thermistor.

Note: The thermistor’s

temperature range is -35

to +135 ohms).
