Air Con Mini Split Air Conditioner Heat Pump Ductless 12000 BTU 21 SEER 1 Ton AC. AU $1,161.99. ... round duct size, weight per linear foot of round duct, surface ... A = Duct Cross Sectional Area X = Duct height in feet Y = Duct width in feet. The equation for a round duct is: A = π x r² A = Duct Cross Sectional Area π= 3.14159 r = radius of duct in feet. Example: An 18” diameter round duct has a Duct Cross Sectional Area of 1.77 Ft². A = π x r² or A = 3.14158 x .5625 These are units of measure that determine an A/C system's size: BTU (British Thermal Unit) - Used to describe how much cooling capacity a home needs. Ton - A measure of the size or cooling capacity of an air conditioner. One ton is equal to 12,000 BTUs. In my book 400 cfm per Ton is the rule. If you can get by with less air, you may be able to cut your TSP in half or more, & still deliver the conditioning required. Even in high velocity, Space-Pak type systems, the airflow is lower (prx 250 cfm per ton I'm thinking) These system will run upward of 2" TSP & care less about velocity, static, & noise. 10 Duct Sizing Duct sizing is determined by the air volume to be delivered. Air volume depends on the amount of heat that the air must deliver and remove. To determine the cooling load for a 1500 ft2 house: 1500/400 X 12,000 Btu = 45,000 Btu/hr (4 ton). There should be six to ten air changes per hour.#3 Ducting. Importance of Choosing the Right Size Unit. What is a BTU? For this example, we would select a 4-ton unit because air conditioner capacities increase in steps of 0.5 ton. If your region is zone 3, requiring only 24BTU per square foot, our example would require an air conditioner capacity...House air leakage* 8 air changes per hour at 6 air changes per hour at 50 pascals pressure 50 pascals pressure Manual J design heating load 46,100 Btu/hr 21,300 Btu/hr Manual J design cooling load 52,100 Btu/hr 23,300 Btu/hr Electric heat pump size 4.0 to 4.5 ton 2 ton (24,000 Btu/hr) (48 to 54,000 Btu/hr) Price and other details may vary based on size and color. ... 4 Ton Goodman 14 SEER R410A 96% AFUE 120,000 BTU Vertical Gas Furnace Split System. 5.0 out of 5 stars 3. • Referring to the Sizing Table, read across the row labeled Sizing Group 50 and down the column containing 1,568 square feet (1,441 to 1,680). • Read down the left-hand (blue) column for an ENERGY STAR qualified home. • This home requires a 3 Ton heat pump. 1Some counties are divided into more than one sizing group.
