  • Page 65 1. Product Features Both indoor units can be operated either simultaneously or separately through the utilization of the advanced converter technique and microcomputer control. The flowing volume of refrigerant is adjustable through the electronic expansion valve. High Cooling and Heating capacity is facilitated through the famous-brand frequency converter compressor. Indoor noise is minimized through the optimization of the air flow system design, a four-folded evaporator and a big diameter Cross Flow Fan.
