Size of the HVAC system (1.5 to 5.0 tons) Rating of the blower in CFM (Most are 350-400 CFM per ton) Square foot of the space served by the HVAC system The equation is: Tonnage x CFM of the blower / Number of s
He holds an HVAC associate degree and EPA & R-410A Certifications.2 thoughts on “How to Find Tonnage Size & SEER from Trane Model Number” Dan Hmmm, I have an older 1999 Trane Dual Compressor 2 stage Heat pump, 5 Ton unit and the numbers don’t match up. I have a variable ...
A kilopascal (kPa) is metric unit used to calculate the force that an object exerts on another stationary object for every square meter of contact. This unit is commonly used in measuring atmospheric pressure and water pressure in metric countries. A Kilo-newton per meter squared (kN/m^2) ...
Since tonnage describes the cooling capacity of your AC unit, it’s important to right-size your system. A unit that’s too small won’t be able to keep up with mid-summer temperatures. An HVAC system that’s too big may turn on and off more frequently than necessary, resulting in unn...
Note:If you would like for us to calculate the kWh usage and running cost of your heat pump, you can give us some numbers (tonnage, SEER, HSPF, cost of electricity or location) in thecomment sectionbelow, and we can help you with the calculations. ...
(CFM) for each room and the house overall and factor in the output of the HVAC system, which you do by dividing 400 (the average HVAC output in CFM/ton) by the square footage to provide a multiplier. The airflow required in each room is then [(HVAC system tonnage x 400) / area ...
There is a limit to the temperature difference across the cooling coil that air-cooled equipment can produce because of the refrigeration cycle. These types of units can typically produce a 20°F to 25°F delta T in the cooling condition. An engineer should always calculate the entering air ...
According to The U.S. Department Of Energy recommendation for the size of room air conditioners: “…an air conditioner generally needs 20 BTU for each square foot of living space.” Based on room size, ceiling height, and other conditions, you can calculate how many BTU air conditioner you...
