Mixed Air Temperature Calculator: Determine HVAC Blend Point

Calculate Your Mixed Air Temperature

CFM
°F

Quickly calculate the mixed air temperature from two distinct air streams, a critical task for HVAC system design, balancing, and energy efficiency. Our intuitive online tool helps engineers, technicians, and homeowners find the perfect blend ratio instantly for optimal comfort and performance.

Formula:

The Mixed Air Temperature (Tmixed) is calculated using the weighted average formula based on volumetric flow rates and temperatures of each air stream:

Tmixed = (V1 × T1 + V2 × T2) / (V1 + V2)

  • Tmixed: Mixed Air Temperature
  • V1: Volumetric Flow Rate of Air Stream 1
  • T1: Temperature of Air Stream 1
  • V2: Volumetric Flow Rate of Air Stream 2
  • T2: Temperature of Air Stream 2
