Division 5 DETERMINATION OF THE AMBIENT CORRECTION TERM Qcor

The ambient correction term is calculated as follows:

1. (a)

   for conventional water heaters using electricity:

   $$Q_{\mathrm{cor}}=-k\times \left(\mathrm{CC}\times \left(Q_{\mathrm{elec}}\times \left(1-\mathrm{SCF}\times \mathrm{smart}\right)-Q_{\mathrm{ref}}\right)\right)$$
2. (b)

   for conventional water heaters using fuels:

   $$Q_{\mathrm{cor}}=-k\times \left(Q_{\mathrm{fuel}}\times \left(1-\mathrm{SCF}\times \mathrm{smart}\right)-Q_{\mathrm{ref}}\right)$$
3. (c)

   for heat pump water heaters:

   $$Q_{\mathrm{cor}}=-k\times \mathrm{24h}\times P_{\mathrm{stby}}$$

Where:

the k-values are given in Table 6 for each load profile.
