An air conditioning system is using R-32 as the refrigerant and the evaporator is cooled by air at a temperature of -15°C. The refrigerant is in the vapor state at the condenser outlet, and the pressure is 4 MPa. The refrigerant is in the liquid state at the evaporator outlet, and the pressure is 0.2 MPa. Determine the mass flow rate of the refrigerant and the coefficient of performance (COP) using the ideal gas equation of state.
