Electrically Driven Compressor


Electrically Driven Compressor ESA34

Car airconditioners make cool inside of cars. Compressor is the heart of car airconditioner.

Generally, compressor is powered by engine and driven with belt.
It is necessary engine running for driving compressor even the time engine should stop such as idle stop. It means compressor leads energy consumption of car.
On the other hand, Electrically Driven Compressor has merits as follows.

  1. It can work by a motor at the time of idle stop, it is compatible in the improvement in fuel
    consumption of car, and comfortable nature.
  2. It is not concerned with an engine movable situation, but can always carry out movable efficiently.

Engine stop time

Electrically Driven Compressor "ESA34" has realized higher energy efficiency and smaller sizing than
our conventional model, and has carried out more environmental consideration.

Improvement of energy efficiency

"ESA34" has been developed aiming higher efficiency by applying new mechanism and carried out higher energy efficiency of 10%* than our conventional model. It has been successed better electricity consumption and better fuel consumption of car.

* In-house testing parameters

Energy efficiency comparison


"ESA34" has carried out more lightweight the main body about 10% than conventional model by downsizing of the inverter, changing the layout, reviewing constitution of the part and reducing conclusion points. It contributes raw material reduction to be used.
