Air duct insulation thickness calculation.

The sharp turns cause a large amount of recirculation regions within the ducts preventing the air from moving smoothly. Ductwork specific pressure loss calculation. 3 2sufficient thermal insulation thickness tm 6 c φ 65 td 22 8 c ta 30 c r flex st kalınlık 9 mm ts 23 6 c td 22 8 c thermal insulation material with a high µ value no condensation. A diffusion tight application is a must minimum insulation thickness 7 6 mm tube diameter 25 4 mm.

Enter the ambient temperature the average temperature of the air surrounding the duct line 3. Hvac calculations and duct sizing gary d. Heat conduction and thermal resistance. There is a high amount of backflow here which again increases the static pressure and reduces the amount of air delivery.

Duct wrap insulation reduces heat loss or gain through duct walls conserving energy. Enter the r value of the selected duct insulation. Enter the perimeter of the duct in inches. Some other factors to consider.

Mass air flow rate unit converter. Air and is a useful tool in air conditioning calculations. General formula to calculate minimum insulation thickness required to prevent condensation t k r t1 t2 t3 t1 where t insulation thickness in k thermal conductivity r surface temperature resistance t1 dew point temperature. Local resistance pressure loss general calculation.

How often do you think you get the full labeled r value. Thermal insulation and ductwork heat loss calculation. Air handling ductwork cross section design. Ductwork seal classes ductwork prone to air leakages.

Enter the flow rate of the air carried by the duct in cubic feet per minute. R 6 duct insulation 6 305 btu hour 0 53 ton r 4 2 duct insulation 7 948 btu hour 0 66 ton the numbers are even higher for the additional heating load. The duct insulation r values i mentioned above are what s on the product label. Fibrous glass duct wrap insulation is designed for application to the exteriors of commercial and residential sheet metal heating ventilating and air conditioning ducts and plenums operating at temperatures between 40 f 4 c and 250 f 121 c.

Note that the r in equation 2 is the factor often found on blanket insulation. Air state calculation during heating and heater output. Ductwork support ductwork support and recommended. The tee section at the far end of the main duct causes the air to suddenly divide and change direction.
