The invention discloses a ground source
heat pump coupling system based on photovoltaic photo-thermal effects. The ground source
heat pump coupling system comprises a grid-connected
photovoltaic power generation system, a solar photo-thermal system and a ground source
heat pump system. On one hand, a PV / T heat collector 1 converts
solar energy into
electric energy, the
electric energy is supplied to a
machine room water pump and a ground source heat pump unit through a photovoltaic controller 2, an
inverter 4 and an alternating-current power distribution cabinet 5,
electricity can be stored in a storage battery 3 or sold in a public
power grid when the
electricity is rich, and the
electricity can be supplemented by the storage battery 3 and the public
power grid when the electricity is insufficient; and on the other hand, after the heat converted by the PV / T heat collector 1 is transmitted to a heat storage water tank 6, the heat is used for supplying hot water through a first
heat exchanger 7, when the heat is rich, the heat can be stored in an underground heat storage
pipe 15 through a second
heat exchanger 16 and used for heating of the ground source heat pump in winter, and when the heat is insufficient, the ground source heat pump can supplement the heat. Compared with a traditional water chilling unit,
coal power generation and other
modes, the operation cost is reduced, and
economic benefits are remarkable,
energy consumption and CO<2> emission are reduced, and the national policies of peak
carbon dioxide emissions and
carbon neutrality are actively responded.
