A. Condenser humidifier—On inspiration, air cools the condenser element. On exhalation, water from the warm air condenses onto the cool element. On the next inspiration, the air is warmed and humidified by the element. B. Hygroscopic condenser humidifier—A low thermal conductivity element is impregnated with hygroscopic salt (calcium or lithium chloride). The salt plus the element capture heat and moisture. During inspiration, the moisture is returned to the gas without cooling. C. Hydrophobic condenser humidifier—Uses a water-repellent element...
