Conventional models can't fully return refrigerant to compressor when returning oil. However, LG's HiPORTM reduces compressor energy wastage by returning oil directly into the compressor, not from refrigerant pipe. Through this, it provides superior efficienct and a high level of reliability.
By extending the path length of the heat exchanger and decreasing the number of paths, the refrigerant is able to throw off more heat. Through a rise in the heat exchange rate, the heat exchanger contributes to increase cooling efficiency.
