A
geothermal heat pump is used in winter for space heating by getting
heat from the ground at 15 °C. The working fluid in the heat pump
is R134a. The compressor inlet is at 400 kPa and the compressor
exit is at 2 MPa and 60 C. The mass flow rate of the refrigerant is
0.1 kg / s and the temperature difference in the air flow in the
condenser section is 12 C. The refrigerant is subcooled to 15 C at
the throttling valve inlet. The specific heat of water is 4200 /kgk
and the specific heat of air is 1000 kJ /kg. Calculate
a . The compressor power
b . The refrigerant temperature at the hot water tank
exit
