Instructions
STEP 1: Click on the main switch to turn on the supply.
STEP 2: Turn on the heater switch.
STEP 3: Now, Turn on the compressor by clicking the compressor switch.
Note – The timer will start and readings will be added to the table automatically until the timer stops.
1 second in a timer is equivalent to 1 min.
STEP 4: Click on the ‘PLOT’ button to plot the graph.
STEP 5: Now, Calculate the Actual COP and Theoretical COP based on the readings and graph.
STEP 6: Click on the ‘PRINT’ button to print the simulation.
STEP 7: Click on the ’RESET’ button to reset the simulation.
STEP 2: Turn on the heater switch.
STEP 3: Now, Turn on the compressor by clicking the compressor switch.
