Authoritative Data Source

Tutti i calcoli si basano rigorosamente sulle formule e sui dati forniti da ASHRAE Handbook - Fundamentals. For further details, visit ASHRAE.

The Formula Explained

Dew Point: \( T_{dew} = T_{dry} - \frac{(100 - RH)}{5} \)

Specific Humidity: \( SH = 0.622 \times \frac{e}{P - e} \)

Glossary of Terms

How It Works: A Step-by-Step Example

For a dry bulb temperature of 25°C and a relative humidity of 60%, the dew point is calculated as 19°C, and the specific humidity is 0.0102 kg/kg.

Frequently Asked Questions (FAQ)

What is a psychrometric chart?

A psychrometric chart is a graphical representation of the physical and thermal properties of moist air.

How do I use the psychrometric calculator?

Input the dry bulb temperature and relative humidity, then click 'Calculate' to see the dew point and specific humidity.

Why is psychrometry important in HVAC?

Psychrometry is crucial for designing HVAC systems as it helps in understanding air properties and behavior under different conditions.

What is relative humidity?

Relative humidity is the amount of moisture in the air compared to what the air can hold at that temperature.

Can this tool be used for educational purposes?

Yes, this tool is designed to assist both students and professionals in understanding and applying psychrometric principles.
