A Mixed Air Calculator is a computational tool (either software-based or manual) that determines the properties of air resulting from mixing two or more air streams with different temperatures, humidity levels, or flow rates. The calculator uses fundamental thermodynamic principles to provide accurate results, ensuring optimal HVAC system performance.
Key Parameters Calculated:
Dry-Bulb Temperature ? The sensible heat component of the mixed air.
Humidity Ratio (or Specific Humidity) ? The moisture content in the mixed air.
Enthalpy ? The total energy (sensible + latent heat) of the mixed air.
Relative Humidity ? The percentage of moisture in the air compared to its maximum capacity at a given temperature.
Why is Mixed Air Calculation Important?
Energy Efficiency
Properly mixed air reduces the load on heating and cooling systems, saving energy.
Helps in optimizing economizer cycles in HVAC systems by determining when outdoor air can be used for free cooling.
Indoor Air Quality (IAQ)
Ensures the right balance of fresh outdoor air and recirculated air, maintaining healthy ventilation rates.
System Performance & Comfort
Prevents issues like uneven temperatures or excessive humidity by ensuring proper air mixing before conditioning.
Cost Savings
Reduces unnecessary heating/cooling by accurately predicting mixed air conditions, lowering operational costs.
