Distributed cold-heat-power combined supply system

Abstract

The invention provides a distributed cold-heat-power combined supply system, wherein a hydrogen production and hydrogen storage system electrolyzes high-temperature water vapor to generate oxygen andhydrogen; a first fuel cell system utilizes oxygen or air and hydrogen to generate power, and transmits the electric energy generated by the power generation to a micro-grid; a second fuel cell systemutilizes hydrogen or natural gas and air to generate power, transmits electric energy to the micro-grid, and combusts the residual hydrogen or natural gas and air to generate flue gas; an absorptiontype refrigerator utilizes the flue gas and the high-temperature water vapor for refrigeration; a hydrothermal management system educes the heat generated when the first fuel cell system, the hydrogenproduction and storage system and the absorption refrigerator operate and supplies the heat to users in the form of hot water; a renewable energy energy-supply system generates high-temperature steam. The distributed cold-heat-power combined supply system can achieve multi-functional complementation, improve energy supply efficiency and energy safety, reduce fossil fuel consumption, has no defectof large CO2 emission, and can achieve combined supply of heat energy, electric energy and cold energy.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a distributed combined cooling, heating and power supply system. Background technique [0002] With the increasingly prominent contradictions in the current energy structure between the supply and demand ends and the power transmission and distribution links of the power grid, the demand for high-quality, personalized and interactive power supply on the user side is becoming more and more urgent, and the distributed power generation and energy storage of renewable energy to realize building The supply of multiple energy sources, on the one hand, can reduce the pressure on the expansion of the power grid, and realize the independent management of energy users including electricity, heat, and cooling, and on the other hand, it can also ensure the reliability requirements of power supply. [0003] It is also worth mentioning that hydrogen energy is considered to be the best energy m...
