Heat Flux Cooling Mode

Overview

Engineering reference data for Heat Flux Cooling Mode in thermodynamics.

Key Formulas

First Law

$\Delta U = Q - W$

Energy is conserved — heat added minus work done.

Ideal Gas Law

$PV = nRT$

Relates pressure, volume, and temperature of an ideal gas.

Heat Transfer

$Q = mc\Delta T$

Sensible heat transfer.

Carnot Efficiency

$\eta = 1 - T_C/T_H$

Maximum efficiency between two temperatures.

Variables

Symbol	Description	Unit
$U$	Internal energy	J
$Q$	Heat	J
$W$	Work	J
$P$	Pressure	Pa

Data Notes

• Conversion factor: $1 \, \text{Btu/ft}^2\text{h} = 3.1525 \, \text{W/m}^2$
• Heat flux values are based on a surface temperature of $85^\circ \text{C}$ and an ambient temperature of $20^\circ \text{C}$.
