Abstract

The invention discloses a hydrogen energy and solar energy complementary type heat and power combined supply system. The system comprises a proton exchange membrane fuel battery power generation system, a steam compression type heat pump system, a solar photovoltaic power generation system, a direct-current bus and a storage battery pack. The proton exchange membrane fuel battery power generationsystem, the steam compression type heat pump system, the solar photovoltaic power generation system and the storage battery pack are connected with the direct-current bus. The current generated by theproton exchange membrane fuel battery power generation system and the current generated by the solar photovoltaic power generation system are stored in the storage battery pack through the direct-current bus or are used for driving the steam compression type heat pump system to heat. Meanwhile, the waste heat of the proton exchange membrane fuel battery power generation system is recycled for heat supply. The system can run in the off-grid mode, and can be used in places without a power grid. Moreover, the supply of electric energy and the supply of heat energy can be taken into considerationat the same time. The system is good in flexibility, high in heating efficiency and high in comprehensive energy utilization rate. The electric energy and the waste heat of fuel batteries are fully utilized. The temperature of the prepared hot water is high (above 60 DEG C).

Description

technical field [0001] The invention relates to the technical field of thermal energy power, in particular to a hydrogen energy and solar energy combined heat and power system and its working method. Background technique [0002] Compared with direct electric heating, heat pumps have higher heating efficiency (the energy efficiency ratio can generally reach more than 3), and have the characteristics of power saving, energy saving and environmental protection. However, since the heat pump still needs to consume high-grade electric energy, its application in places far away from the grid is limited. [0003] Solar photovoltaic cells can make full use of the inexhaustible, inexhaustible and cheap sunlight to generate electricity. It is a clean and pollution-free power generation method. However, due to the intermittent nature of solar energy, there are sunny days and cloudy days. There are no nights during the day, so it is not convenient to use in places where a stable energy...
