For model : AV-G1248, AV-G1264, AV-G1296, AV-G33184#B, AV-G33206#B, AV-G01184#B, AV-G01208#B และ AV-G01206#B

1. Calculating the volume of the building

   Formula (put the size of the building)	Wide	x	Long	x	High
   	90	x	120	x	5
   Volume of the building =	54,000.00 m2

2. Calculating the volume of air must transplant out
   
   Select the deployment to determine the amount of air to flow out of the building by the AIRCHANGE / hour which is defined as operating conditions

   Style deployment (installation point)	Number AIRCHANGE / HR.
   Warehouse	5-7.5
   Repair plant / Factory	10-15
   Machinery room/ Plant	15-25
   Kitchen (with a lot of heat).	25 or more
   Spray Booth/ Dry Booth	30-100

   Formula	Volume of building	x	AIRCHANGE / HR.	÷	60 minutes
   	54,000.00	x	25	÷	60
   The air must transplant out =	22,500.00 CMM

3. To find the number of fans that will be installed
   
   The ability of ventilation fan of each model is

   AV-G1248			=			165 CMM.
   AV-G1246			=			180 CMM.
   AV-G1298			=			275 CMM.
   AV-G1296			=			325 CMM.
   AV-G33184#B			=			50 CMM.
   AV-G33208#B			=			90 CMM.
   AV-G33206#B			=			111 CMM.
   AV-G01181#B			=			50 CMM.
   AV-G01208#B			=			90 CMM.
   AV-G01206#B			=			111 CMM.

   
   The formula for fan (Select models fan to be installed from the top) MODEL: AV-G1298 (example)

   The air must transplant out	÷	The ability of the fan required	=	The number of fans that will be installed.
   22,500.00	÷	275.00	=	81.82 set

   
   *** Calculating may vary depending on operating conditions. Each building has different conditions. ***
   Note : An example of this calculation is the installation of a ventilation fan for Machinery room/ Plant
