Task 4.1: Basic cycle
For a process with the refrigerant R290 the condensation temperature $\theta_c = 35 \degree C$ and the
evaporation temperature $\theta_v = -30 \degree C$ are given.
The requested refrigeration capacity is $\dot{Q}_0 = 10 kW$. The flow chart with the four points of state
depicts the simplest setup of a compression refrigeration machine.
Determine:
a) $p, \rho, h$ for all points of state as well as the specific volume
at the suction side of the compressor (List values in a table!)
b) refrigerant mass flow
c) refrigerant volume flow at the suction side of the compressor
d) theoretical compressor power
e) condensation capacity
f) specific volumetric refrigeration capacity
g) theoretical coefficient of performance
