Photovoltaic and photo-thermal renewable energy multi-storage recycling system

Abstract

The invention discloses a photovoltaic and photo-thermal renewable energy multi-storage recycling system. The photovoltaic and photo-thermal renewable energy multi-storage recycling system comprises asolar water heater, a temperature supply pipe network, a power plant pipe network, a sewage pipe network, a waste gas network and an energy storage pipe network. The solar water heater is connected with the temperature supply pipe network, the temperature supply pipe network is connected with the sewage pipe network through a sewage heat pump, and the temperature supply pipe network is connectedwith the waste gas pipe network through a waste gas heat pump. Sun, sewage, waste gas and underground heat energy can be effectively utilized and effectively combined to supply heat and cold to cities, the photovoltaic and photo-thermal renewable energy multi-storage recycling system is installed at multiple underground places and independently controlled to supply cold and heat to each building,the pipeline arrangement cost during central heating is reduced, and the use of heating boilers and the power consumption during summer cooling are reduced; and urban energy configuration is integrated, the construction cost and the tail gas treatment cost of multiple heating plants are reduced, the heating plants are integrated into a large power plant, centralized consumption and centralized tail gas treatment are facilitated, and the urban energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of energy-saving buildings, in particular to a multi-storage and recycling system for photovoltaic and photothermal renewable energy. Background technique [0002] About 46% of the world's energy is consumed in the final form of thermal energy. Thermal energy storage is also an important branch of energy science and technology. In the process of energy conversion and utilization, there are often contradictions between supply and demand in time and space. The peak-to-valley difference of load, the intermittence and volatility of renewable energy such as solar energy and wind energy, etc. Energy storage methods include mechanical energy, electromagnetic energy, chemical energy and thermal energy storage. Thermal energy storage includes wet heat storage and latent heat (phase change heat) storage. Moist heat storage is carried out by using the inherent thermal fusion of materials. Latent heat storage, or phase...
