There are many factors that may affect the equivalent COPE of this ORBCR using moist air for air
conditioning cooled by circulating water. These include the pressure ratio of the axial compressor, P4/P3,
the efficiencies of the axial compressor and turbine, the wet bulb temperature of the atmosphere Twet and
the wet air temperature of turbine inlet, T7.
During simulation, the pressure ratio of the axial compressor varied from 1.6 to 2.5, the wet bulb
temperature of the outdoor air from 20 to 30 °C and the temperature at 6 is 7-12 °C higher than the wet
bulb temperature of the outdoor air. The temperature of the air-conditioned room is 24 °C at 50% relative
humidity. The temperature of the circulating water from the cooling tower, which is cooled by the outdoor
air, is 3-4 °C higher than wet bulb temperature of the outdoor air. The temperature of the water from the
cooling tower, which is cooled by the air discharged from air conditioned room, is about 20-22 °C and
the mass flow rate of the cooling water is 0.75kg/s.kg(da). The wet air temperature at 7 is 20-30 °C .
