Thermal / HVAC Workflow

Carry one humid-air state through humidity ratio, dew point, wet bulb, surface condensation risk, target conditioning state, sensible/latent cooling duty and condensate production.

PsychrometricsCondensation checkCooling load splitRuns locally

01 — INLET AIR

Define the humid-air state and airflow.

Use local conditions representative of the air entering the HVAC process or thermal zone.

Dry-bulb temperature°C Relative humidity% Absolute pressurekPa Volumetric airflowm³/sThe dry-air mass flow is derived from the inlet specific volume.

02 — TARGET CONDITION

Define the air state after conditioning.

The enthalpy and humidity-ratio difference provides a screening cooling/dehumidification duty.

Target dry-bulb°C Target relative humidity%This is a target air state, not an automatic coil apparatus-dew-point model.

03 — CONDENSATION SCREEN

Check a critical surface against dew point.

Use the coldest relevant surface temperature you know or expect.

CONNECTED THERMAL LOGIC

Humidity, condensation and cooling load are the same thermodynamic story.

The workflow keeps the inlet air state consistent while moving from psychrometrics into a target conditioning process and a local surface-temperature check.

It is intended for engineering screening and CFD/thermal setup—not as a replacement for a full building-load, coil-selection or transient thermal model.

State. Temperature, RH and pressure define vapor pressure, humidity ratio and enthalpy.

Dew point. Vapor pressure defines the saturation temperature where condensation becomes possible.

Conditioning. Enthalpy and humidity-ratio changes define sensible/latent duty and moisture removal.

Surface risk. Compare the critical surface temperature with dew point before interpreting local CFD temperature fields.
