Psychrometry Calculator
Psychrometry is the science of studying moist air and its thermodynamic properties, which is fundamental to HVAC system design and analysis. It helps engineers understand how air behaves when it contains water vapor, affecting comfort, energy efficiency, and equipment performance.
Key psychrometric properties include dry bulb temperature, wet bulb temperature, dew point, relative humidity, humidity ratio, and enthalpy. These properties are used to calculate cooling loads, determine dehumidification requirements, size air conditioning equipment, and optimize system performance according to standards like ASHRAE guidelines.
Formula:
\[
\omega = 0.62198 \times \left(\frac{P_v}{P_{\text{atm}} - P_v}\right), \quad h = 1.006 \times T_{\text{db}} + \omega \times (2501.4 + 1.86 \times T_{\text{db}})
\]
