Heat Pump System Performance with PV System Adapted Control

摘要

Combination of heat pumps with PV systems could significantly reduce the use of grid electricity from external supplier for space heating and hot water application. The paper presents an analysis of using PV adapted control for heat pump operation in two different alternatives and compares such advanced approach with conventional static approach. Both alternatives of the adapted control for the heat pump system achieve high solar fraction about 39% compared to conventional approach (16%) and more than 30% higher seasonal performance factors.
