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