Ground screws must be #32 thread pitch or finer and must be threaded into the metal box. #10-32 is the "conventional" size. Most metal boxes have a hole that is tapped for a #10-32 screw. This is visible as a hole slightly smaller than the normal mounting holes.
To avoid possible nuisance tripping of the thermal cutouts due to insufficient airflow, a minimum airflow of 70 cfm (33L/s) per kilowatt must be maintained. For Single Duct Terminal Units, A minimum of .1” w.g. (25 Pa) of downstream static pressure is required to ensure proper .If electric heat was chosen, based on the calculation above you would choose a 1 .Terminal units reduce energy costs and minimize carbon footprint. Daikin’s single duct VAV boxes, from 80 to 8000 CFM, provide high performance and set the standard in the industry for construction, performance, and quality. The heating airflow is recalculated using the sensible heat equation to determine the actual heating airflow that is required to satisfy the heating load. Q_heating = k*cfm_heating*(T_heating_room - T_heating_supply)
Pressure Independent VAV with Heater(Variable Air Volume Terminals) • Pressure Independent VAV Unit has one primary air inlet, one rectangular discharge outlet to the room and one rectangular bypass discharge outlet. • . Sizing a VAV box seems simple but often the scheduled boxes on plans have not considered pressure drop and noise. Using a max of NC-30 and specific pressure drops as . The minimum of the vav box should be sized to meet the ventilation requirements of ASHRAE standard 62. If this overcools the space you need to reset your supply . If electric heat was chosen, based on the calculation above you would choose a 1 kw heater. Nailor offers electric heaters in .1 kw increments starting at .5 kw, allowing you to choose the exact amount needed for your .
Superior FlowStar air measuring probe provides for lower minimum cubic feet per minute (CFM) values, which reduces energy costs and noise while maintaining comfort in the zone. An .A popular option for heating and cooling perimeter zones. 100–4100 CFM; PSC or EC motor options; AHRI 880 and ETL certified What is the heat loss to the space? What is the minimum air flow to the space based on OA%? Then use the 1.08*(CFM)*(dT) to determine how much heat you are getting from the .

Pressure Independent VAV with Heater(Variable Air Volume Terminals) • Pressure Independent VAV Unit has one primary air inlet, one rectangular discharge outlet to the room and one rectangular bypass discharge outlet. • VAV box Capacities range from 40– 4000 CFM in 7 sizes. Sizing a VAV box seems simple but often the scheduled boxes on plans have not considered pressure drop and noise. Using a max of NC-30 and specific pressure drops as limits, the table below attempts to compile a realistic cfm range for each given box size. The minimum of the vav box should be sized to meet the ventilation requirements of ASHRAE standard 62. If this overcools the space you need to reset your supply temperature or add reheat. 30% is a rule of thumb but definitely not code. If electric heat was chosen, based on the calculation above you would choose a 1 kw heater. Nailor offers electric heaters in .1 kw increments starting at .5 kw, allowing you to choose the exact amount needed for your application.

The manufacturers want 70 CFM per KW for electric heat in the FPB'S. You can get by with a little less but if you have 30 and 50 CFM the heater has to be smaller than 1 KW. If not the heat will not energize.Superior FlowStar air measuring probe provides for lower minimum cubic feet per minute (CFM) values, which reduces energy costs and noise while maintaining comfort in the zone. An integrated VAV box with direct digital controls allows for a bundled offering with lower total installation costs.A popular option for heating and cooling perimeter zones. 100–4100 CFM; PSC or EC motor options; AHRI 880 and ETL certifiedTo avoid possible nuisance tripping of the thermal cutouts due to insufficient airflow, a minimum airflow of 70 cfm (33L/s) per kilowatt must be maintained.
