A large refrigeration plant is to be maintained at -18 ∘C, and
it requires refrigeration at a rate of 210.0 kW . The condenser of
the plant is to be cooled by liquid water, which experiences a
temperature rise of 8 ∘C as it flows over the coils of the
condenser. Assume the plant operates on the ideal vapor-compression
cycle using R-134a as the working fluid between the pressure limits
of 120 kPa and 700 kPa
A)
Determine the mass flow rate (m˙) of the
refrigerant.
Express your answer to three significant figures.
B)
Determine the power input (W˙net) to the
compressor.
Express your answer to three significant figures and include the
appropriate units.
C)
Determine the mass flow rate (m˙) of cooling water.
Express your answer to three significant figures.
Write all units please.
