Development of distributed multiple‐source and multiple‐use heat pump system using renewable energy: Outline of test building and experimental evaluation of cooling and heating performance

Abstract

AbstractThe development of a distributed heat pump system that utilizes several renewable energy sources to meet building heating and cooling demands was reported in this paper. We refer to this system as the multiple‐source and multiple‐use heat pump (MMHP) system. A unique sky source heat pump, ground heat exchangers, and various heat pumps are connected through closed‐loop piping system within a building. This kind of configuration enables improved matching of supply and demand which offers a high flexibility. The winter and summer field testing are conducted to investigate the system performance using a testing building.
