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.

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.
