refrigerant is decreased with increasing of spray water rate,
and the condensing temperature is also decreased. So, the
cooling capacity and COP are increased with increasing water
spray rate.
On the other hand, the cooling capacity and COP of the air
conditioning system with dual independent evaporative
condenser are increased with air velocity increasing from
2.05 m s1 to 3.97 m s1. Under the condition of the water
spray rate is 0.04 kg m1 s, the cooling capacity and COP
increased from 47.23 to 53.43kW and 4.26 to 4.82, respectively.
This mainly due to the higher air velocity improved the heat
exchanger coefficient, and the condensation temperature and
the pressure decreased.
