Auto Cooling System in the Outdoor Unit
A tightly sealed electrical part box fends fine sand particles from getting in to protect high-accuracy inverter circuit. And a genuine Auto-Cooling System fends the temperature inside the box from rising owing to heat generated by the base.
Fine sand blow in from the desert is vastly fine and can result in damage if it enters electronic circuit in the inverter. However, shielding the base of the inverter inhibits heat from escaping, causing the internal temperature to grow too high and damage the inverter control system. This problem was solved with the growth of the innovative auto cooling system.
The new outdoor unit design utilizes cool refrigerant and a fan to fends the temperature of the electronic circuitry rising.
