WebAshrae Bangalore WebEarlier ASHRAE heating and cooling load methods include the total equivalent temperature differential/ time-averaging method (TETD/TA), the transfer function method (TFM) and the cooling load temperature differential (CLTD)/solar cooling load (SCL)/cooling load factor (CLF) method [4]. The transfer function method (TFM) is a two-step procedure. little andromeda christchurch
