(using 0°C reference): [ h = c_p,a \cdot T + W \cdot (h_g + c_p,v \cdot T) ] Typically: ( c_p,a \approx 1.006 \text kJ/kg·K ), ( c_p,v \approx 1.86 \text kJ/kg·K ), ( h_g \approx 2501 \text kJ/kg ) at 0°C.
Tec Tube 1m Show all Dry-Bulb Temperature (DBT): The air temperature measured by a standard thermometer. Wet-Bulb Temperature (WBT): Measured by a thermometer with a wet wick; it indicates how much moisture the air can absorb through evaporation. Relative Humidity (RH): Expressed as a percentage, showing how saturated the air is compared to its maximum capacity. Dew Point Temperature: The temperature at which water vapor begins to condense into liquid. Humidity Ratio (Specific Humidity): The actual weight of water vapor per unit weight of dry air. Enthalpy: The total heat energy (sensible and latent) contained in the air-water mixture. YouTube +6 Review of Applications The psychrometric table is highly regarded for its utility in several critical areas: HVAC Design: Engineers use it to plot "comfort zones" (typically between 22
In simple terms, air isn't just "air"—it’s a mixture of dry gases and water vapor. The amount of water vapor air can hold changes based on temperature and pressure. The psychrometric table maps these variables so you don't have to perform complex calculus every time you want to adjust a thermostat. Key Variables in a Psychrometric Table
The actual mass of water vapor per unit mass of dry air (vertical y-axis).
While it might look like a daunting wall of numbers, a psychrometric table is one of the most powerful tools in thermodynamics and HVAC (Heating, Ventilation, and Air Conditioning). What is a Psychrometric Table?
