Sponge city building photovoltaic integrated utilization system

Abstract

The invention relates to a sponge city building photovoltaic integrated utilization system. The sponge city building photovoltaic integrated utilization system comprises a roof green ecological system, an automation rainwater irrigation device, a solar PV / T system and an underground rainwater refrigeration and heating device, wherein the roof green ecological system, the automation rainwater irrigation device, the solar PV / T system and the underground rainwater refrigeration and heating device are connected with a building. The sponge city building photovoltaic integrated utilization system has the advantages that the green ecological system is built on a roof, so that the cyclic utilization of the rainwater is achieved and the rainwater utilization rate is increased; the electric energy obtained by the solar PV / T system is stored to an accumulator and is supplied for an axial flow draught fan and an centrifugal water pump to use, and thus the automation of rainwater irrigation and underground rainwater refrigeration and heating can be achieved; a heater which is arranged at the lower side of a photovoltaic panel in the solar PV / T system uses photovoltaic heat to conduct heating on the rainwater in a water feeding pipeline, so that the rainwater is used for a user and the reutilization of the rainwater is achieved; the stored rainwater in an underground impounding reservoir can be maintained at a constant temperature, the rainwater is subjected to full heat exchanging with air in a pipe through a heat exchanging pipe section, and the stored underground rainwater can be used as a cooling medium to conduct refrigeration in summer and can be used as a heating medium to conduct heating in winter.

Description

Technical field [0001] The invention relates to a sponge city photovoltaic building integrated utilization system. Background technique [0002] With the expansion of the scale of cities, the green area of ​​the earth has gradually decreased, the greenhouse effect has intensified, and the heat island effect within the city has also intensified, resulting in the result of the high summer temperature in the city, and the urban precipitation is caused by the lack of water storage by vegetation roots. Draining along the urban sewage drainage channels will form a waste of water resources. In addition, urban precipitation has certain requirements on the urban drainage system. If the drainage is improper, the formation of stagnant water will affect the beauty of the city and the comfort of residents. [0003] The existing sponge city system (such as patent CN 105830774 A) can only collect and utilize a small amount of rainwater, has a low rainwater utilization rate, and fails to well solv...

AI Technical Summary

Problems solved by technology

[0002] With the expansion of the city, the green area of ​​the earth is gradually reduced, the greenhouse effect is intensified, and the heat island effect in the city is also intensified, resulting in the high temperature in the city in summer, and the urban precipitation is due to the lack of water storage by the roots of the vegetation. Drainage with urban sewage drains will result in waste of water resources. In addition, urban precipitation has certain requirements on urban drainage systems. If drainage is not done properly, water accumulation will be formed, which will affect the appearance of the city and the comfort of residents.

[0003] The existing sponge city system (such as patent CN 105830774 A) can only realize the collection and utilization of a small amount of rainwater, and the utilization rate of rainwater is low, and it cannot solve the problems of urban flooding and waterlogging well.
