A hybrid chiller is sort of a combination of an air-cooled chiller and a cooling tower. Hybrid chillers use the principle of evaporative cooling to help with heat rejection in addition to their own fans. Hybrid chiller are more efficient than air-cooled chiller but still, they are less efficient than water-cooled chillers. Most of the time, hybrid chillers have an efficiency of around 0.75 kW/ton.
ETCO Hybrid Cooling is more efficient and compact than conventional air-cooled or water-cooled systems. This is made possible because evaporative condensers operate based on the wet-bulb temperature, which is consistently 8–14°C lower than the dry-bulb temperature. This means that even in intense outdoor heat, an evaporative condenser can still operate at a lower condensing temperature
