The eco-visionCentral Air Conditioning Energy ConservationSystem
offerscustomers
1) a high rate of reduction in energy usage using our patentedtechnology
2) reliable verification
3) remote operation (safetysupport).
Our technology reduces energy use by approximately65-95%.
The systemachieves both decreased CO2 levels and lowersyour electric bills
without altering the normal operation method ofthe airconditioner.

Control panelincludes an inverter, PLC(programmable logic controller),
electriccontrol circuits, and acommunications router.
Principles ofelectric power reduction:
The pump''selectricity consumption is equal to the flowcontrol rate cubed.
As the graph shows, a flow rate of 1/2 corresponds to 1/8 (12.5%)electricity usage;
a flow rate of 1/4 corresponds to 1/64 (1.5%) electricityusage.
When the air conditioner''s system load is low, the hot/cold waterflow rate is
tightly controlled, yieldingan astonishing 80–90% reduction in energy usage.
Operation control when working under heavy systemload:
The system loads of building-wide air conditioning systems arealways fluctuating.
Ordinary pumps operate at 100% regardless of system load, with afixed rate
of electricity consumption.
eco-vision''s pump flow control regulates power use according tothe system load,
allocating as little power as necessary to meet changing systemrequirements.
This results in decreased electricity consumption, as shown in theimage.
(The electricity consumption of the pumps decreases inproportion to the flow rate cubed.)
eco-vision system:
eco-vision uses an inverter to regulate the primary hot/cold waterpump,
the secondary pump, and the coolant pump.
Computerized sensors installed throughout the system analyze datasuch as flow rate,
temperature, and pressure to ensure the most precise power controlpossible, achieving
a high rate of electricity conservation.
After acquiring a patent in Japan, we acquired apatent
in the United States.
Monitorscreen:
The eco-visionsystem constantly monitors the pump operating statusand
electricityusage, storing thedata and displaying it on this dedicated screen.
Graph verifying reduction in electricityuse:
This overview graph displays operation data collected daily,monthly,
and yearly, showing at a glance the results of using the eco-visionsystem.
Return oninvestment:
Electric bills begin to fall the day our equipment isinstalled.
Although equipment and operating conditions vary, your investmentwill pay
for itself in about 2.5 to 5 years.
Aneco-vision installation at a 26, 000m² shoppingcenter
resulted in a74.5% annualdecrease in electricityconsumption.
Largereductions in power usage can beexpected even forlarge-scale equipment,
such as for amusement parks.
An eco-vision installation at a 203-roomhotel reduced CO2emissions
by 206 tons in oneyear.eco-vision is veryenvironmentally-friendly.
An eco-visioninstallation at a 415-bedhospital reducedannual costs
by 7, 800, 000 yen. Hospitals that must operate their airconditioning
24 hours a day can expectsimilar savings.
An eco-visioninstallation at a 238-bedhospital decreased
monthlyelectricity consumption rates by92.1%.
