Abstract

The embodiment of the invention provides a dual-mode energy supply system, and belongs to the technical field of heat supply. The system comprise a wind heat unit, a photovoltaic unit and an energy storage assembly, wherein the wind heat unit comprises a wind turbine, a compressor, a throttle valve, an evaporator and a condenser, the wind turbine is in transmission connection with a driving shaftof the compressor, the compressor communicates with the evaporator and the condenser through refrigerant pipelines, and the condenser communicates with the evaporator through the refrigerant pipelinesvia the throttle valve; the photovoltaic unit comprises a solar photovoltaic panel and a first inverter, and the power supply end of the solar photovoltaic panel is electrically connected with the input end of the first inverter; and the energy storage assembly comprises a heat storage water tank and a storage battery, a water inlet of the heat storage water tank communicates with the condenser through a water pipe, a water outlet of the heat storage water tank communicates with a heat water supply end of a user end, an input end of the storage battery is electrically connected with an outputend of the first inverter, and an output end of the storage battery is electrically connected with a power supply end of the user end. According to the system, the clean energy application of solar photovoltaic power generation is realized and the power generation efficiency is improved.

Description

technical field [0001] The present disclosure relates to the technical field of heat supply, and in particular to a dual-mode energy supply system. Background technique [0002] With the increase of urbanization rate, the dismantling of small regional boilers and the transformation of pipe networks in old urban areas, there is a huge gap in my country's urban centralized heating. The heat coverage rate is still at a low level. At present, only the main towns in the northern provinces have central heating systems, and the average coverage rate is less than 50%. Rely on independent heating methods such as natural gas furnaces, air conditioners, electric furnaces and honeycomb coal for heating, while the coverage rate of central heating in cities in developed countries such as Finland and Denmark reaches 90%, and the national average level is also above 60%. [0003] my country's urban heating industry still uses coal as the main fuel, and its annual coal consumption exceeds 150...
