City Hospital Kitchen
to � Modification
The present kitchen hood and its present operational procedure
accounts for the consumption of 7,000 gallons of fuel being exhausted
as heat loss per year. This figure was supplied by calculation of
the building air temperature, the fans C.F.H. capacity and the degree
day temperature for the year. This was done by Dick Hartford of
Carpenter Associates.
After a review of the present equipment and taking the kitchen
operations into consideration the following recommendations are being
made.
1. Change the badly deteriorated hood fan to a more economical
design. The present hood is a single speed motor rated at 3
H.P. exhausting at 12,500 C.F.M. The new fan will be 2
speed with a rating of 6,000 C.F.M., using a 1 1/2 H.P.
motor. The design of the new fan will eliminate the huge
exhaust vent on the roof. Thin will help eliminate much of
the down draft when the unit is turned off.
2. We also propose to install a back draft damper in the dish
washer vent duct work, which at the present time has none.
3. Also we propose to install a removable stainless steel blank
over the grill vent hood located in the dining area.
6. We propose to install removable stainless steel blanks over
half of the kitchen hood to cut the air flow in half during
the heating season.
With the new equipment and change in the fan operation procedures
it is possible to cut the waste in fuel by better than two thirds the
amount being presently exhausted from the kitchen area.
Thank you

The application of Sound filings to various tan innanabons
produces different sound rating requirements. Also, Soma

CENTRIMASTER PERFORMANCE CHART
The charts on the following pages 8 had 18 show the
complete performance range of each exhauster for Se-
lection of the model having the characteristics best
suited for the ventilation system.
The static pressures are plotted as curved diagonal lines
shown on adlacenl page. Each Cenlrimasler exhauster
s represented onthe charts byavertical rectangle con-
taining its model number. The space between the lop
and bottom dashed lines attached to the rectangle
shows that model's complete range of RPM and lip
speed with the corresponding CFM and static pressure.
HOW TO USE THE CHARTS
From the capacity fibers on pages 4.5.8 and 7, Select
the exhauster models or sizes that most nearly meet the
design requirements. It more specific performance re-
quirements are desired, then refer to the appropriate
charts to make the Final selections.
Example:
Suppose your ventilating system requires 1200 CFM at
.250" static pressure, The capacity table On page 8
shows this performance is available with the Model PU
145E 1. PU 141 or PU I45E. To select the one model
having the parmrmance range desVed, refer to the NN
145 chart.
1. Locale the 1200 CFM line and follow It up to the
diagonal .250 SP curve. This is your design point.
2. Horizontally to the left read 387010th tip Speed
3. Horizontally to the right read 1040 RPM, Select the
model offering the performance range preferred.
4, Read sound rating at 8 7 Sones and 87 LwIAI.
5. In general. any design paint will be Covered by two or
more sizes of exhausters. It different performance
characteristics are desired from those lust deter-
mined. refer to performance charts on other pages.
VENTILATION SYSTEM RESISTANCE CURVES
In any Given Ventilating system, the statlo pressure
once for the system. This is particularly Imo when using
experiment equipped with variable pi+Oh bell drives
which make changes in airflow possible.
A system resistance curve accurately determines the
w static pressure for any change in the airflow of a
ventilatina system. It is easily constructed on any at the
