The air conditioning system's dual independent evaporators
and condensers employ a common shell, respectively.
The evaporative condenser includes a frequency convertible
water pump and two axial flow fans, and the evaporative
condenser water pump and fan are also frequency convertible,
and the frequency can be adjusted from 30 to 100 Hz. The
frequency convertible water pump conveys water from the
tank to the pressure spray system with downward directed
nozzles, and the frequency convertible fan conveys the
convertible air speed from the bottom grille to the top outlet.
Meanwhile, the dual independent evaporative condenser includes
two heating exchange coils: precooling coils and
condensing coils. In cooling mode, the superheat gas discharged
from compressor is cooled into saturated gas in precooling
coil, and then, it is further condensed into subcooled
liquid through the condensing coil. The schematic and main
parameters of the dual independent evaporative condenser
are shown in Fig. 3 and Table 1, respectively.
