Estimated savings
-
£92k
in annual energy costs in 2 +
years
15% increase in
HVAC efficiency
Cut back from
four 300-ton chillers to two |

The
pressure drop across the coil
decreased by over 30%
The
airflow increased from 16,000
CFM to 17,400 CFM
30% increase in cooling capacity
from 548,502 BTU to 797,094 BTU
The
devices ability to increase
system performance to almost “as
new”levels and is expected to
prolong the life on mechanical
equipment
Potential Horse power savings
should not be ignored especially
for those who utilise VAV drives |

The Florida
Hospital Group
|
Within
weeks of installing the UVC the
air velocity across the coil
more than doubled from 230 fpm
to 520 fpm
The wet bulb temperature
decreased from 57°F-53°F
We
calculated the increase in
capacity to 95,245 BTU saving
£3,300
on an investment of
£2,000.00
The hospital is
conservatively saving 15% in
HVAC system energy costs |

Rio Grande
Hospital
|
Before UVC
The
chillers serving the hospital
were running at 99% capacity
Chilled water “in” measured at
43°, while chilled water “out”
measured at 64°
After UVC
The same
chillers were running at only
62% capacity
Chilled water “in” remained at
43°, but chilled water “out”
temperature had decreased to
53°, an 11 degree drop
Electrical
usage (in kilowatt hours)
declined by 20.64%
This essentially cancelled out
an equivalent rise in utility
rates from $.06 per kWh to $.08
per kWh
