Building distributed energy supply system based on hydrogen fuel cell and operation method

Abstract

The invention discloses a building distributed energy supply system based on a hydrogen fuel cell and an operation method. The building distributed energy supply system comprises a hydrogen fuel cell system, an air source heat pump system and a waste heat recovery system; the hydrogen fuel cell system generates electric power, and the electric power stored by a storage battery is used for driving a compressor and supplying power to a building; and when the air source heat pump system is in a refrigeration mode, a refrigerant prepares chilled water for refrigeration through a plate heat exchanger, when the air source heat pump system is in a heating mode, the refrigerant extracts heat from air through a finned heat exchanger and prepares hot water for heating through the plate heat exchanger, and the waste heat recovery system recovers waste heat of the hydrogen fuel cell for preparing domestic hot water and serves as an auxiliary heat source of the air source heat pump system when the temperature is low in winter. The electric power and waste heat of the hydrogen fuel cell are fully and reasonably utilized, the purposes of building power supply, refrigeration, heating and domestic hot water supply are achieved, the energy utilization rate is increased, the current energy policy requirements of energy conservation and emission reduction are met, and social benefits are remarkable.

AI Technical Summary

Benefits of technology

This new design allows for better integration between different systems like cooling/heating, electricity generation, or thermo-water collectors (thermal) while also allowing it to use waste heat from recovered hydrogen gas batteries during cold weather conditions. Additionally, this technology could help improve the overall performance of these devices through utilizing their waste heat sources such as hot water and outside air heat exchange with an external condenser.

Problems solved by technology

This patented describes how different types of renewable sources like wind power or solar panels could help reduce carbon emissions from existing fossil fuelling plants while also being more efficient than older methods such as coal gas firing. Additionally, it suggests that this method may use residual thermal energy generated by burning off excessive materials during combustion instead of disposing them separately after each usage period. Overall, these technical means aimed towards create a better way to produce electrical energy without causing significant negative impact upon our environment.
