Coefficient of Heat Transfer in Air Conditioning Systems Formulas

The Coefficient of Heat Transfer is the heat transferred per unit area per kelvin. Thus area is included in the equation as it represents the area over which the transfer of heat takes place. And is denoted by h. Coefficient of Heat Transfer is usually measured using the Watt per Square Meter per Kelvin for Heat Transfer Coefficient. Note that the value of Coefficient of Heat Transfer is always negative.
