Cooling Technology-Refrigerators

Multiple vents have replaced the conventional single vent, particularly in large refrigerators. One vent for each shelf allows uniform distribution of temperature in the refrigerator. This increases cooling efficiency as compared to the single vent airflow system. Various refrigerator brands give their multiple vents different terms and names like Cross Flow System, Intelflo, 3D Surround, Express, Super X, 3D Cooling , Green Ion Door Cooling etc.
