Absorption Chiller “Efficio”

Kawasaki had developed the highest efficient absorption chillerin the world in 2013

Note) COP is based on LHV


Steam Absorption Chiller “Efficio”

The Efficio delivers high annual operational efficiency by adopting a parallel-flow, solution invertercontrol and larger absorbent solution storage tank. These features ensure excellent efficiencyacross the full range of load conditions, contributing to greater energy savings.

The Efficio employs below items for highly efficient operation at partial load.

Parallel Flow

Solution Pump Inverter Control

Larger Absorbent Solution Storage Tank

Parallel flow can be operated with highefficiency at partial load.

Solution pump inverter control so that it canbe operated with high efficiency at partialload.

The larger absorbent solution storage tankprevents the heat transfer tubes in thesolution at low load. It can keep heat transferarea.

Partial Load Characteristics

Cooling water inlet temperature conditions are as specified by the JIS standards (32℃ at 100% load, 27℃ at 0% load, with the temperature varying proportionally at loads between 0% and 100%).
