The interior lighting of the refrigerators is provided by
incandescent lamps whose switches are actuated by the opening of the
refrigerator door. Consider a refrigerator whose 30-W lightbulb
remains on continuously as a result of a malfunction of the switch. If
the refrigerator has a COP of 1.4 and the cost of electricity is Rp
1200/kWh, determine the increase in the energy consumption of the
refrigerator and its cost per month (1 month = 30 days) if the switch
is not fixed. Assuming the refrigerator is opened 50 times a day for
an average of 30 s.
COP= QL/(QH-QL)
COP= Qin/Win
Please help me for this. thanks a lot!
