  • How do Choose the right size air cooler for our room?
    Nov 13, 2018

    Now more and more people choose to use portable evaporative air coolers which are built to maximize energy efficiency and keep costs low.Evaporative cooling system without compressor cools naturally, efficiently and inexpensively.

     

    What is best size for my place?The key to choosing the right size air cooler is  choosing one with the right rating for your space.This amount of air that passes through the cooler per unit time can be measured in CFM (Cubic Feet Per Meters) ,or CMH (Cubic Metre Per Hour. As a rule of thumb, the higher a air cooler's air flow, the faster it cools the air and better coverage in your space.

     

    Calculating Air flow volume

    Calculating CFM

    The CFM (Cubic Feet per Minute) is the amount of fresh air cycled through your environment each minute. To find the CFM, follow this formula:

    Formula for Evaporative Cooler Sizing

    Room Length x Room Width x Ceiling Height = Cubic Footage

    Cubic Feet / 2 = Cubic Feet Per Minute (CFM)

    For example, if your room is 250square feet(Room Height 25 foot, Room Width 10 foot)with 8-foot ceilings:
    25 X10X 8 /2 = 1000CFM

    According to the equation, you would need a air cooler with a CFM of at least 1000.

    251 to 500 sq.ft

    1001 to 2000 CFM

    501 to 1000 sq.ft

    2001 to 4000 CFM

    1001 to 2000 sq.ft

    4001 to 8000 CFM

     

    Calculating CMH

    The CMH(Cubic meters per hour) is the amount of fresh air cycled through your environment each hour. To find the CMH, follow this formula:

     

    Formula for Evaporative Cooler Sizing

    Room Length x Room Width x Ceiling Height = Cubic Meters

    Cubic Meters x30 = Cubic Meter Per Hour (CMH)

    For example, if your room is 20 square meters (Room Height 5 meters, Room Width 4 meters) with 2.4 meters ceilings:
    5X4X2.4X30 = 1440 CMH

    According to the equation, you would need a air cooler with a CMH of at least 1440.

    Recommended CMH

    41 to 60 sq.m

    2881 to 4320 CMH

    61 to 80 sq.m

    4321 to 5760 CMH
