6 Appendix Temperature measurements T IN, T OUT and T R of the solar collector under different operating conditions I. Taking measurements with the water temperature at the collector inlet T IN 10 0 C and in the absence of lighting. 1. Reduce and stabilise the water temperature at the collector inlet to T IN 10 0 C. To achieve this, fill the reservoir with an integrated heat exchanger (8 in Picture 1) with ice cubes and chilled water. Stir thoroughly. The contents of the reservoir should be stirred, throughout the course of the measurements, approximately every 2 minutes. Maintain a constant temperature of the reservoir by adding ice cubes as necessary. 2. Turn on the water pump power (5 in Picture 1), and set the voltage knob to 4 V and the current limiter control knob to 1 A. 3. Open the circulation pump valve to maximum (Picture 2). Picture 2. Circulation pump: 1 - flow rate control valve; 2 - flow rate indicator. 4. Using the water pump valve, set the flow rate to 100 cm 3 /min. When making measurements, continuously monitor the rate of water flow circulating through the collector. Instytut Fizyki Doświadczalnej 5.

7 5. Use a digital temperature meter (Picture 3) to note the temperatures at the inflow T IN and outflow T OUT of the collector and in the heat exchanger reservoir T R every minute for 30 minutes. After completing each measurement, stir the water with ice cubes in the reservoir. Picture 3. Digital thermometer: 1 - displays indicating the temperature of the selected input channel; 2 - input channels, red light measured temperature is displayed on the upper display, green light - on the lower display; 3 - channel control buttons, from the left: change the channel input, change the temperature scale, change mode, zero reset; 4 shows selected temperature scale. 6. Repeat measurements in points I in the Appendix for the collector without windows and rear panels. II. Taking temperature measurements with the water temperature of the collector inlet T IN 20 0 C and with lighting. 1. Place the heater in the heat exchanger reservoir (8 in Picture 1). While stirring, heat the water to a temperature of about 20 0 C, then turn off the heater power. During subsequent stages of the experiment, one should regularly stir the water in the reservoir to maintain a constant water temperature at the collector inlet. Instytut Fizyki Doświadczalnej 6.

8 2. Set the halogen lamp at a distance of 70 cm from the collector, and set the collector perpendicular to the direction of the incident light. Turn on the lamp. The lamp housing can become extremely hot! It is forbidden to touch it as well as the ventilation grills. The lamp should be turned off immediately after completing the measurements. 3. Take measurements as in of part I of the Appendix and perform calculations as in of Experimental Tasks. 4. Repeat step II.3. of the Appendix for the collector without glass and rear panels. III. Taking temperature measurements with the water temperature of the collector inlet T IN 40 0 C and with lighting. 1. Turn on the lamp. 2. Increase the rate of water flow to 200 cm 3 /min. 3. Place the heater in the heat exchanger reservoir and heat the water to about 40 0 C. Monitor the water temperature carefully during the experiment. Take a series of measurements as in point 3. Of part II in the Appendix. 4. Repeat the steps from 3. in part II of the Appendix for the collector without glass. 5. Set the hairdryer at a distance of 30 cm from the glass of the collector. Set it to blow cold air. Carry out the steps in point 3. in part II of the Appendix. 6. Turn off the lamp and hairdryer. 7. Turn the power supply voltage knob to the minimum and then turn off the water pump. 8. Drain the water tank with the drain tap. Instytut Fizyki Doświadczalnej 7.
