## Main Question or Discussion Point

hello everybody,

in fact,im asking for a help in a matter confused me alot,its about how can i select the right (split,mini split,portable,window,etc) air conditioner,which is not central air conditioner.

im working now in a company and they size the air conditioner for the customer according to the floor area,when i asked about it"how to size?",they told me the"3*3*3"m^3 is a size for 1hp air conditioner,that was the 1st confusion,when they said hp,as a unit i thought of it as its the conversion from the BTU to the hp,and when i calculated it it didnt give their hp they work with;),anyway thats not what im asking about for now.

so,i figured out that they divide the BTU by 8,for ex:the 12000btu=1.25hp,the 18000=2.25hp and so on,thats not my point now,my point when i googled how to size i got this table which if i know the floor area in feets i'd get the estimated size of the right air conditioner with the BTU then i'd convert it as they do to hp,thats the link of the table,please take a look, http://fedders.stores.yahoo.net/sizingguide2.html [Broken] .

i found that this table doesnt match at all to the values they working with,and the boss told me thats too much for their sizing for the split air conditioner,of course i converted from feets square to meter squares,as thats the metric units we work with here.

so my question is:

how from the floor area i find the right size for the split air conditioner?

in BTU and i'd estimate it to the hp as they convert it,and would like to find a table like that one but in meters square;),may it would be a bit different estimation?,just confused so please help from anyone here knows about that,or have worked in the air conditioning field before,and especially the small units,the splits,i know if it was central we calculate the cooling load and then we find the capacity as ive studied at school.

thanks alot for ur time,and waiting ur reply.
