Refrigeration Governing Equations
Cooling Capacity (Q_evap)
Q_evap = m_dot * (h1 - h4)
Compressor Work (W_c)
W_c = m_dot * (h2 - h1)
Coefficient of Performance
COP = Q_evap / W_c
Mass flow rate is 0.10 kg/s.
Isentropic efficiency of the compressor is 80%.
Condenser saturation pressure is 1.20 MPa; evaporator saturation pressure is 0.20 MPa.
