Evaluation of the Combination of Hybrid Photovoltaic Solar Thermal Collectors with Air to Water Heat Pumps

摘要

Recently, hybrid photovoltaic solar thermal collectors (PVT) became a topic of many research projects because of the possibility to gain heat and electricity simultaneously. PVT represents the alternative to PV panels and solar thermal collectors in one device. The main goal of this study is to evaluate different possibilities to integrate PVT collectors in an air to water heat pump system and to compare the results with the combination of an air to water heat pump system together with a PV-system. Three different hydraulic systems for the heating system integrated with PVT have been simulated in this study. The possible increase of self-consumption and reduction of primary energy consumption by applying a special control to store electrical energy as heat has been investigated. The effect of this control on the performance of the PVT collectors has been determined. Full costs for the different heating systems were calculated.
