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 ...
On top of that, when you usethis calculator for how many BTU air conditioners you need, you will also have to understand what AC tonnage that is. Conversely, when you use theAC tonnage calculator here, it might be useful to convert those tons into BTU to give you a better understanding ...
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) ...
Lucky for you, we already taught you that math! Simply divide the BTUs by 12,000 to calculate the tonnage of your unit. For example, if your air conditioner is 36,000 BTUs, you have a 3-ton unit. Some manufacturers bury tonnage or BTU information in their model numbers. Look for an...
(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 ...
knowntonnage(or BTUs), theSEER rating, and theHSPF rating, we can calculate almost exactly how much electricity a heat pump use (watts, kWh usage)per hour,per day, and evenper month. Based on that, we can calculate how much it costs to run a heat pump per hour, per day, and per...
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...
