Device for generating, refrigerating and heat supplying by solar energy and biomass energy

The invention provides a device for generating, refrigerating and heat supplying by solar energy and biomass energy, comprising a solar absorption device, a generating device and a biomass high-temperature heating furnace (7). The device is characterized in that an exhaust pipe of a high-energy heat accumulator (2) of the solar absorption device is communicated with the inlet of a first disc-shaped or spiral heating pipe (7.1) arranged in the biomass high-temperature heating furnace (7); and the outlet of the first disc-shaped or spiral heating pipe (7.1) is communicated with an air inlet pipe of a decompressor of a medium-temperature expansion-air motor (4) of the generating device. The device has the advantages that the system ensures that heat energy can be utilized efficiently to reduce exhaust of carbon dioxide; investment and electric energy consumption of refrigerating equipment can be saved simultaneously; the biomass high-temperature heating furnace is connected in parallel when sunlight is not sufficient so as to effectively complement heat energy to ensure that the unit can work continuously; and the device for generating, refrigerating and heat supplying by solar energy and biomass energy has high energy conversion efficiency, and is suitable for popularization.
