A heat pump is used to heat water by extracting heat from ambient air. This system is turned to be used to cool a room by extracting heat from the air and reject it to water. The

heat pump has a COP of as a heating system The room receives heat energy from

outside at kJh The work done by the compressor is kW The system uses an

idealvapour compression cycle. i just need letter e please

a Draw the schematic of the setup clearing labelling the components and the relevant

energy exchanges.

b What is the rate of heat rejection? Is this enough to meet the cooling requirements and

maintain a constant temperature.

c If the ambient temperature in the room was to decrease, what does this mean for the

COP. How would the work input of the compressor be affected.

d Draw a Ts diagram of the system, clearly label the states at relevant sections.

It is Given that the coefficient for heat conduction between the working fluid and ambient air

is given to be INm K what is the area required for the evaporator. You can

assume an average temperature of degrees C between the evaporator and
