The outdoor air at 2 is drawn into the atomizing chamber (AC), cooled into the saturated air at 3 with
some fine water droplets, and then compressed by an axial compressor(c). A flow of compressed air at 4
with a higher temperature, T4, and a high pressure, P4, is obtained. Then the compressed air at 4 is firstly
cooled into the saturated air at 6 with a temperature of T6 by circulating water in a surface heat (SHE) after
the axial compressor outlet. The saturated air at 6 is then cooled into the saturated air at 7 with a
temperature of T7 in another surface heat exchanger (SHE) before the turbine inlet by the water that is
cooled by the return air at 9, which is discharged from air-conditioned rooms. Some water vapor is
condensed and the latent heat of the vapor is discharged from 4 to 7. Then the saturated air at 7 is expanded
and cooled into the cold air at 8 in the turbine (T). The cold air at 8 is then ducted to the air-conditioned
rooms (ACR).
