Meet refrigeration adopts the third Generation shape-c arc-eveporator, which utilizes the air-driving flow theory. Smooth outer and inner faces of the Evaporator can guarantee a well-proportioned distance and fluent airflow between indoor crossflow fan and heat exchanger, thus avoids the whirl of airflow and reduces the working structure, the C model increases the heat exchanging area by 15-30% and raises the heating and cooling speed by 12-25% in the same efficient space.
