1. Lucy PV chiller could be set use solar PV cooling or heating model and only electricity cooling or heating model.
2. Lucy PV chiller take advantage of solar PV for cooling first, when the solar radiation is not enough use electricity to be backup energy, cooling capacity change from 100% to 0%, and electricity power change from 100% to %.
3. Fouling factor for chiller water is 0.086 ºC/kw.
