How is SplitCool different from the high-SEER “DC Inverter” air conditioners that are becoming so popular?
The “DC Inverter” type air conditioner is the most efficient type of AC powered air conditioner system available today. It is also the basis of the SplitCool design, we just took it a few steps further to optimize it for DC power. In a normal “DC Inverter” air conditioner, AC power is the input, then an internal rectifier circuit converts the power to DC, and from there the power goes through an inverter circuit into the motor as variable frequency 3-Phase AC power. Therefore in order to run a normal “DC Inverter” air conditioner from solar, the solar DC would have to be inverted to AC, then converted back to DC, then inverted back to AC. In the SplitCool system there is no rectifier and no inverter. The DC power is fed directly into the digital frequency controller where the DC power is pulsed into the brushless motor.
