(Air Volume)
The efciency of the heat exchanger has been greatly
enhanced by adding an additional column to the hybrid heat
exchanger which increased the surface area.
The loss of heat has been reduced by using tubes of varying
diameter.
By reducing the second vortex which decreases airow within the air outlet and
enlarging the fan size, the amount of airow is increased from 420 cfm to 550 cfm.
How It Works
The number of suction ports have been reduced to
one to increase the efciency of refrigerant
compression at low compressor low speeds.
High efciency digitally controlled motor.
The advanced inverter drive
minimizes energy loss and
keeps the efciency level high
at 95%.
While energy loss is incurred in the process of switching voltage
between AC & DC, inverter drive keeps this loss minimal for
improved energy efciency.
