Problem 21.35
In winter, you like to keep your house interior at
21.0 °C. Your geothermal heating system, which
was advertised as being reversible, draws thermal
energy from an underground reservoir at 348 K. In
a cold winter, with the average outdoor
temperature being 0.0 °C thermal energy escapes
from the house at a rate of 1000 W±5%.
Distributing the thermal energy supplied by the
heating system throughout the house requires
174 W (provided by the heating system). Ignore
any inefficiency in converting electrical energy to
mechanical energy.
