11.4.14 _TC1 (Thermal Constant 1)<br />

This object evaluates to the constant _TC1 for use in the Passive cooling formula:<br />

Performance [%]= _TC1 * ( Tn - Tn-1 ) + _TC2 * (Tn. - Tt)<br />

Arguments:<br />

None<br />

Return Value:<br />

An Integer containing Thermal Constant #1<br />

11.4.15 _TC2 (Thermal Constant 2)<br />

This object evaluates to the constant _TC2 for use in the Passive cooling formula:<br />

Performance [%]= _TC1 * ( Tn - Tn-1 ) + _TC2 *(Tn - Tt)<br />

Arguments:<br />

None<br />

Return Value:<br />

An Integer containing Thermal Constant #2<br />
