This paper describes hybrid heat pump air-conditioning system(GeoSIS HYBRID). GeoSIS HYBRID is hybrid heat pump system combining ground source heat pump (GSHP) and air source heat pump (ASHP) . GSHP air-conditining system use stable underground heat throughout the year and can be operated without being outside air temperature. But install costs of underground heat exchange is expensive. We reduce install costs of underground heat exchange and build the interlocking control in accordance with the outside air temperature and load change by GeoSIS HYBRID.
