Return air duct size chart. Installation standards and demands are adhered to in order to produce a standard of performance across the career field and ensure the professional installation of hvac systems. Duct system sizes and airflow quick chart created date: Furnace filters come in a range of sizes, and different brands and types of furnaces use different filters.

This is the required airflow through the return grille. “for the same 2.5 ton system with a filter grille, the grille size would need to be what size?” asked rick “we usually use a 20 x 20 for 2.5 ton.” said the tech 20 x 20 x 2 = 800 “800 cfm…well that’s big enough for a 2 ton, but a 20 x 25 may be a better choice.” Wxh wxh wxh wxh wxh wxh wxh wxh 80 6x6 7x5 9x4 90 7x6 8x5 10x4 100 7 8x6 9x5 11x4 125 7x7 9x6 11x5 13x4 150 8x7 9x6 12x5 15x4 175 8 8x8 9x7 10x6 13x5 17x4.

A furnace return system must collect all the air being put out by that system. The last step is to size the return grille and duct to match the total of the supply registers. • to insure proper distribution of air, volume dampers must be used for all branch runs.

You can obtain these from ductwork manufacturers or from industry bodies such as cibse and ashrae. Select duct size using friction chart or duct calculator how: Never locate ducts at the end of the trunk line run.

Proper sizing and orientation of grilles, registers, and diffusers may seem like such a simple thing, but it’s an area where confusion and mistakes are commonly made. Your 14 x 20 return air inlet = 280 sq. The size of a grill, the mechanical movement of air, and the mathematics that govern the establishment of correct return air vents are determined by these organizations.

Psychrometric chart a psychrometric chart is a graphical representation of the properties of moist air and is a useful tool in air conditioning calculations. If the furnace is putting out 1,000 cubic feet per minute of air flow, the return system must collect 1,000 cubic feet and take it back to the unit. Calculate the return duct size based on the air conditioner's size and the type of duct you are using.
