Beschreibung
Zusammenfassung:	The utility model relates to the technical field of drying of solar agricultural products and materials, and in particular relates to a heat supply and drying system employing solar photovoltaic and heat pump combined energy. The system comprises a solar photovoltaic system, a solar heat collector, a heat pump system, a heat storing and supplying water tank, a heat exchange system, a drying system and a control system; the solar photovoltaic system, the heat collector and the heat pump are combined to use, and thus three mode functions can be performed for enabling the water temperature of the heat supplying water tank to reach the specified temperature, then the water is conveyed to the heat exchange system of a drying chamber, air pressurized by a centrifugal fan flows through a heat exchanger for exchanging the heat and finally enters the drying chamber to dry the material. The drying system employing the solar photovoltaic and solar heat pump combined energy has the advantages of being clean, efficient and energy-saving; the material drying efficiency is raised, and the production cost is decreased.
