The invention relates to the technical field of combined cooling, heating and power systems, and discloses a combined cooling, heating and power system based on thermoacoustic effects and pyroelectric effects, including a thermoacoustic engine, a thermoacoustic refrigerator, and a pyroelectric power generation unit. The acoustic engine, the thermoacoustic refrigerator, and the pyroelectric power generation unit are connected through a resonance tube; the pyroelectric power generation unit includes a first high-temperature heat exchanger and a first room temperature heat exchanger respectively located at both ends of the first high-temperature heat exchanger and the second room temperature heat exchanger, the first high temperature heat exchanger and the first room temperature heat exchanger are connected by a set of pyroelectric material plate stacks, and the first high temperature heat exchanger and the second room temperature heat exchanger are connected by The first heat buffer tube is connected or connected through another group of pyroelectric material plate stacks; the pyroelectric material plate stacks are used for connecting external circuit loads. The combined cooling, heating and power system has no moving parts, which can effectively solve the problem of low reliability of mechanical moving parts. At the same time, the system can collect and utilize solar energy and waste heat.
Description
technical field [0001] The invention relates to the technical field of combined cooling, heating and power systems, in particular to a combined cooling, heating and power system based on thermoacoustic effects and pyroelectric effects. Background technique [0002] Energy is one of the key factors affecting human survival, development and progress. The excessive exploitation and use of fossil fuels at this stage has made energy and environmental problems increasingly serious. Exploring green and energy-saving technologies has gradually become an important development trend of the global energy environment. The combined cooling, heating and power supply system uses cascaded energy to provide users with electric energy, heat energy, cooling energy and domestic water at the same time, which can effectively improve energy utilization efficiency and is a high-efficiency energy comprehensive utilization method that has attracted much attention. [0003] The combined cooling, hea...
