Infinity heat pump system only comes in 1 ton steps.
Would it be better to be a little under or little over in size.
Looks like 23% under or 15% over going by Dash's calculations between 3 ton or 4 ton unit
Load calc. by Flajoker's ac man came up to 33000.. spec used 95 degrees outside and 73 degrees inside.
I do like to keep it at 70-72 in summer..maybe with the dehumidfy Flajoker won't need to go so low.
relative hunidity is 84 day, 61 night on gulf coast
Dash's words of wisdom in quotes (Flajoker copied from another post)
"Take a typical ton,26,800 sensible and 7,200 btus latent,total 34,000 btus."
"Read the fine print of mfrs rating,rated at 80°F indoor(return) air,deduct 835 btus ,per 1000 cfms ,for every degree below 80."
Flajoker asks(Is there a web page with the mfrs fine print on it? Why do they only rate unit to cool to 80 degrees? Why does it loose capacity below 80 degrees?)
Do they have a high number for heat as well?
"So 1200 cfms,equals 1.2 X835 btus X 8° below 80°=8016 btus to deduct ,from rated capacity."
Flajoker says(I have no idea what the above means or how you got it. Could you please explain where cfms number comes from"
"So deduct 8016 sensible btus,and a 3 ton is too small."
"Check detailed cooling charts,most will have a nominal 3 ton that will handle it,but not if you want 72° in cooling,75° maybe"
Flajoker could not find chart on web.
This is amazingly interesting and informative.
I have a new found respect for Hvac trade and work involved in getting it right.
Thanks everyone for their comments and help
