A heat pump with COP of 2.0 is used to heat water to 90 oC for cleaning purpose. This heat
pump absorb heat from surrounding at 30 oC and received the entire power, ̇ from a
Carnot heat engine operating between 200 oC and 25 oC. The Carnot heat engine received
6.3 kW of heat from the high temperature source.
i) Draw the schematic diagram of the above system.
ii) Determine the power received by the heat pump, ̇ from Carnot heat engine, kW.
iii) Calculate the rate of heat supplied to the water by the heat pump, kW.
iv) Determine the COP of the heat pump if it operates on a reversed Carnot cycle.
