1-1-1 Feature (cont.)

Application of wide fin

High efficient heat exchanger has been applied, therefore it delays the onset of frost formation and increased heat transfer efficiency.
Optimized cooling/heating and increased system efficiency! Liquid EEV & Turbo Inter-cooler
• Liquid EEV for increased efficiency of the system
Through Liquid EEV, controlling of valve opening has become more efficient and it achieved optimized system efficssiency and
minimized noise from the refrigerant in the indoor unit.
• Turbo Inter-cooler
High performing shell & tube type heat exchanger has been applied to secure cooling/heating efficiency. It has secured enough
subcooling to acquire reliability on long piping and it also increased cooling/heating efficiency.
