Solar heat pump system and work method thereof

Abstract

The invention discloses a solar heat pump system and a work method thereof. A water storing bag type photovoltaic assembly, a pump machine assembly, a water bag circulating pipeline, an indoor circulating pipeline, a middle pipeline and a temperature gauge are included, wherein the water storing bag type photovoltaic assembly is arranged on the surface of a roof, and comprises a photovoltaic assembly for converting solar energy into electric energy, a water storing bag arranged on the back side of the photovoltaic assembly and a water bag support used for supporting the water storing bag; thepump machine assembly comprises one or more heat pumps; part of the electric energy converted by the photovoltaic assembly is used for providing electric power supporting for the heat pumps, and the heat pumps are used for achieving water circulation; the water bag circulating pipeline is used for communicating an underground water source or an external connection water source with the water storing bag; the indoor circulating pipeline is arranged indoors and used for circulating the underground water source or the external connection water source; the middle pipeline communicates with the water bag circulating pipeline and the indoor circulating pipeline, and is provided with a temperature control valve; and the temperature gauge is arranged on the indoor environment. Double-circulation design is adopted for the solar heat pump system, so that the summer cooling and winter heating effect can be effectively achieved.

Description

technical field [0001] The invention belongs to the field of solar photovoltaics, and in particular relates to a solar heat pump system and a working method thereof. Background technique [0002] At present, solar energy has been effectively popularized as a new type of new energy. In particular, crystalline silicon photovoltaic modules account for a major proportion of the entire solar energy industry. When the photovoltaic module is used as a power generation unit to supply power to the system, the photovoltaic module itself will generate heat at the same time. Under normal circumstances, the temperature of the photovoltaic module even reaches 60°C. The temperature rise has an impact on the power generation efficiency, and the power temperature coefficient of crystalline silicon photovoltaic modules is 0.3-0.5% (the temperature rises by 1°C, and the power drops by 0.3-0.5%).
