WEEK 15

OBJECTIVE:

• to prepare for engineer day presentation.

ACTIVITY:

• Analysed the last output for all type.
• Making poster for engineer days

            The result from  Figure 4.2, 4.3,4,4 has been combine at Figure 4.3. Form this result can be analysed the best output will generate between the type. Blue line is result for type 1, red line is result for type 2 and green line for type 3.  The maximum power in type 1 is 4.6W. The maximum power in type 2 is 4.37V and 5.6W in type 3. There is no much difference between type 1 and type 2 because the difference temperature cold side and hot side is not much between type 1 and 2.  Thermoelectric principle is when the difference temperature is increase, the higher output will generate. Type 3 has most large max power between other type because of the large difference temperature between inside and outside building temperature.

In this week need to do demonstration and presentation about development and performance analysis PV-TE energy harvester prototype on building wall by using labVIEW.

ENGINEER'S DAY

WEEK 14

OBJECTIVE:
To measure the value  of IV characteristic using labVIEW.

ACTIVITY:

• Continue to construct the labView block diagram.
• Continue solve the problem with the circuit and labVIEW and DAQcar
•  To measure and determine the value of voltage and current. 
• To measure the power output produce.
•  To generate IV graph using labVIEW

Figure above are shown how the constructions of the block diagram. From the figure show that there is a loop to place DAQ assist, multiplier, numeric and meter to measure voltage and current. At voltage part, the value must multiply by 2 because the voltage at the hardware has been dividing into two because of voltage divider.  It compulsory to multiply the voltage value. The result will be show at the graph and numeric indicator.

            At the current part, the value must multiply by 6 because of using 6 resistor in this project. The value of the resistor is 82Ω. . Connect all the output from solar panel and thermoelectric module to the circuit and connect the voltage and current wire to DAQ card. Run the labView software in order to get IV graft. Increase the value of variable resistor from 0Ω to 1kΩ.

The power produced by the cell in Watts can be easily calculated along the I-V sweep by the equation P=IV.   the value of power is 4.6W

The value  power of the type 2   is 4.37W

The value  power of the type 3   is 5.6W

From this project, the best max power generate is type 3 compare with other type due to the higher difference temperature between cold and hot side. All information and the result have been representing in the graph

WEEK 13

Objective:

• To measure the value  of IV characteristic using labView.

Activity:

• Continue to construct the labView block diagram.
• Continue solve the problem with the circuit and labVIEW and DAQcard

This project will be used variable resistor to make the load increase. The value of variable resistor used is 1kΩ. from the variable resistor, can see there is a change when the value is increase. All this change will be show and discuss below.

 labVIEW block diagram

           The specification of the DAQ card (SBC-68) are provide in the laboratory is The Maximum Voltage can support by DAQ card only 10V. Need Voltage divider (V_D) circuit to cut the value output value into half. The current part, DAQ card cannot measure the current directly. Also need external circuit (current divider, I_D) to measure the current. By using ohm law’s, the current can be calculated when there is a voltage and resistor (V=IR). 

In conclusion, the objective of this work didn't achieve because of the IV graph cannot meet the specification. the graph show that the output in inverse output. 

WEEK 12

Objective:

• To measure the value  of IV characteristic using labView.

Activity:

• construct the labView block diagram.
• connect the data acquisition( DAQ) card from Output Circuit to computer.

   In this week need to construct block diagram at labVIEW software. In the labVIEW has been place the DAQ assist, multiplier, numeric indicator and meter to measure voltage and current, and XY graph to plot XY characteristic.

      This part will testing  all the result with all type of place thermoelectric. Firstly, test and measure the output of photovoltaic and thermoelectric place inside the building with air conditioning temperature. Secondly, test and measure the output value of photovoltaic and thermoelectric place outside the building. Lastly, test and measure the output value of photovoltaic and thermoelectric place outside and inside the building. All the result (Current vs. Voltage) will display in the labVIEW using XY graph.

      The objective of this week not achieve because of the value of Voltage and current cannot be measure. the value at the labVIEW only shown the higher value of Voltage and current and didn't show the exact value in the variable resistor increase and decrease.
