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

This paper reports the development of a distributed heat pump system that can utilize several renewable energy sources to meet building heating and cooling demands. We called this a multiple source and multiple use heat pump (MMHP) system. A water circulating loop is used to connect ground heat exchangers, a unique sky-source heat pump, and various heat pumps for heating and cooling purposes within a building. This increases the flexibility of the system and allows improved matching of supply and demand. An experimental house was constructed, winter and summer field experiment were conducted to investigate performance of this system.
