The embodiment of the invention provides a dual-mode
energy supply system, and belongs to the technical field of
heat supply. The
system comprise a wind heat unit, a photovoltaic unit and an
energy storage assembly, wherein the wind heat unit comprises a wind
turbine, a compressor, a
throttle valve, an
evaporator and a condenser, the wind
turbine is in transmission connection with a driving shaftof the compressor, the compressor communicates with the
evaporator and the condenser through
refrigerant pipelines, and the condenser communicates with the
evaporator through the
refrigerant pipelinesvia the
throttle valve; the photovoltaic unit comprises a solar photovoltaic panel and a first
inverter, and the power supply end of the solar photovoltaic panel is electrically connected with the input end of the first
inverter; and the
energy storage assembly comprises a heat storage water tank and a storage battery, a water inlet of the heat storage water tank communicates with the condenser through a
water pipe, a water outlet of the heat storage water tank communicates with a heat
water supply end of a user end, an input end of the storage battery is electrically connected with an outputend of the first
inverter, and an output end of the storage battery is electrically connected with a power supply end of the user end. According to the
system, the
clean energy application of solar
photovoltaic power generation is realized and the power generation efficiency is improved.
