Steam Absorption Chiller “Efficio”
The Efficio delivers high annual operational efficiency by adopting a parallel-flow, solution inverter
control and larger absorbent solution storage tank. These features ensure excellent efficiency
across the full range of load conditions, contributing to greater energy savings.

Partial Load Characteristics

The Efficio employs below items
for highly efficient operation at partial load.
Parallel Flow
Parallel flow can be operated
efficiency at partial load.

withhigh

Solution Pump Inverter Control
Solution pump inverter control so that it canbe operated with high efficiency at partialload.
Larger Absorbent Solution Storage Tank

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

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