Average Heat Transfer Coefficient in Air Conditioning Systems Formulas

Average Heat Transfer Coefficient is equal to the heat flow (Q) across the heat-transfer surface divided by the average temperature (Δt) and the area of the heat-transfer surface (A). And is denoted by h ̅. Average Heat Transfer Coefficient is usually measured using the Watt per Square Meter per Kelvin for Heat Transfer Coefficient. Note that the value of Average Heat Transfer Coefficient is always positive.
