Individual fan systems with a design supply air capacity of 5000 cfm or greater and minimum outside air supply of 70%or greater of the supply air capacity must have an energy recovery system with at least a 50%effectiveness.Exceptions:- Systems serving spaces that are not cooled and heated to<60 degrees F.-Commercial kitchen hoods(grease)classified as Type 1 by NFPA 96-Systems exhausting toxic,flammable,paint,or corrosive fumes or dust If an air economizer is also required,heat recovery must be bypassed or controlled to permit air economizer operation. 16. Individual kitchen exhaust hoods larger than 5000 cfm must be provided with make-up air sized for at least 50%of exhaust air volume that is uncooled and either unheated or heated to no more than 60 degrees F Exceptions:-Where hoods are used to exhaust ventilation air that would otherwise exfiltrate or be exhausted by other fan systems.-Certified grease extractor hoods that require a face velocity no>60 fpm. 17. Buildings with fume hood systems having a total exhaust rate>15,000 cfm must either have variable air volume hood design, exhaust air heat recovery,or separate make up air supply meeting the following makeup air requirements:-at least 75%of exhaust flow rate-heated to no more than 2 degrees F below room setpoint temperature-cooled to no lower than 2 degrees F above room setpoint temperature-no humidification added-no simultaneous heating and cooling College Station Fire Station#3 Page 10 of 10 COLLEGE STATION FIRE STATION NO. 3 PRESSURE LOSS CALCULATIONS ZONE 1 - CRITICAL ITEM S G L L U TK COPPER 2 1/2" 50.00 1 .80 1 .25 1 .80 x 1 .25 = 2.25 METER 2" 50.00 M 2.70 PVC-CLASS 200 2 1/2" 50.00 55' 0.80 .55 x .80 = .44 DOUBLE CHECK VALVE 2 1/2" 50.00 CV 3.00 PVC-CLASS 200 2 1/2" 50.00 55' 0.80 .55 x .80 = .44 PRESSURE REDUCER RK-CLASS 200 2 1/2" 50.00 60' 0.57 .60 x .80 = .48 VALUE 2" 50.00 V 3.00 PVC-CLASS 200 2 1/2" 50.00 20' 0.57 .20 x .80 = .16 PVC 1 1/2" 24.38 18' 1 .09 .18 x 1 .09 = .1962 PVC 1 " 12.72 5' 1 .83 .05 x 1 .83 = .0915 PVC 1" 11 .66 22' 1 .83 .22 x 1 .83 = .402 PVC 1" 10.60 22' 1 .56 .22 x 1 .56 = .343 PVC 1" 9.54 22' 1 .30 .22 x 1 .30 = .286 PVC 3/4" 8.48 22' 3.55 .22 x 3.55 = .781 PVC 3/4" 7.42 22' 2.85 .22 x 2.85 = .627 PVC 3/4" 6.36 22' 2.23 .22 x 2.23 = .4906 PVC 3/4" 5.30 22' 1 .68 .22 x 1 .68 = .3696 PVC 1/2" 4.24 22' 3.23 .22 x 3.23 = .7106 PVC 1/2" 3.18 22' 1 .90 .22 x 1 .90 = .418 PVC 1/2" 2.12 22' 0.90 .22 x .90 = .198 PVC 1/2" 1 .06 22' 0.25 .22 x .25 = .055 TOTAL = 17.4453 ACTUAL HEAD PRESSURE: 70 PSI - 17.4453 = 52.5 DESIGN HEAD PRESSURE: 25 PSI + 1 7.44 = 42.44 170 > 42.44
