| For Chillers
[(DTPOST – DTPRE)*QBLDG / 5.5] * 1/COP_CH
Where COP_CH = 0.605*COP_CHSM + 0.395*COP_CHWN
COP_CHSM = (COPaSM + COPbSM)/2; COP_CHWN = (COPaWN + COPbWN)/2
QBLDG = 0.605*[0.77*(0.88*NCHSM*QCHSM + 0.12*NCHWN*QCHWN)] + 0.395*[0.596*(0.184*NCHSM*QCHSM + 0.816*NCHSM*QCHSM)]
For VSD CHWP circuit
(SkW_CHWPPRE – SkW_CHWPPOST) *OPHR,yr
Where SkW_CHWPPRE = 0.605*LFSM,PRE*(0.88*NCHWPSM*kW_CHWPSM + 0.12*NCHWPWN* kW_CHWPWN) + 0.395* LFWN,PRE *(0.184*NCHWPSM*kW_CHWPSM + 0.816*NCHWPWN*kW_CHWPWN)
SkW_CHWPPOST = (DTPRE/DTPOST)^1.35*S kW_CHWPPRE
For VSD: LFSM = 0.795, LFWN = 0.562;
For EC or DC-motor: LFSM = 0.71, LFWN = 0.38
OPHR,yr = hr/day*day/wk*52
