A 16" round flex duct will accommodate up to a 3.5 ton unit
Ducts not the right? Size would be the? 4 tons = 1600cfm = 18" round duct or 16"x16" rec. duct.
For a 3-ton HVAC unit, the recommended duct size typically ranges from 12 to 14 inches in diameter for round ducts, or about 8 to 10 inches in width for rectangular ducts, depending on the design and layout of the system. The exact size may vary based on factors such as the length of the duct runs, the number of bends, and the overall airflow requirements. It's essential to perform a proper load calculation and consult local building codes to ensure optimal performance and efficiency.
14" Round or 14" x 12" Rec. will work.
Yes replace the three ton and four ton unit with another three ton or or four ton unit. If you looking to combine the units it may need some re-engineering of the ducts, evaporators, and air handlers either to combine or zone the two ? duct system.
Bond's Work Index is typically expressed in kilowatt-hours per ton (kWh/ton). It represents the energy required to reduce a material from infinite size to 80% passing a specific screen size in a grinding circuit.
For a typical 5-ton package unit, the supply duct size is usually around 18 to 20 inches in diameter, while the return duct size is typically around 20 to 24 inches in diameter. However, these sizes can vary based on the specific design and airflow requirements of the system. It's important to refer to the manufacturer's specifications and local building codes for precise dimensions. Proper sizing ensures optimal airflow and efficiency for the HVAC system.
