Solar energy-wind energy coupled cold-electricity co-production energy system

Abstract

The invention provides a solar energy-wind energy coupled cold-electricity co-production energy system, which comprises three subsystems, namely a wind energy storage and power supply system, a solar organic Rankine cycle system and a cold supply system, and is characterized in that the wind energy storage and power supply system is formed by connecting a wind driven generator, power storage equipment and three working medium pumps; the solar organic Rankine cycle system is formed by sequentially connecting a solar heat collector, a working medium pump, a heat tank, an expansion machine, a generator, a condenser and a heat exchanger; the cold supply system is formed by sequentially connecting an evaporator, a refrigeration house, a compressor, a condenser, an expansion valve, a working medium pump and a cold tank. By means of the mode, the energy utilization efficiency can be effectively improved, solar energy and wind energy are mutually coupled, power is provided for the generator, and meanwhile the refrigeration house can be refrigerated. Therefore, the device has a wide application prospect.

Description

Technical field [0001] The present invention relates to the field of new energy sources, in particular refers to a solar - wind energy coupled cold - combined power energy system. Background [0002] In China, the power industry is the most important source of current carbon emissions, and its carbon emissions account for more than 1 / 3 of all carbon emissions. Therefore, the core of China's realization of the "double carbon" goal is to build a new power system with new energy power generation as the main body, promote the construction of low-carbon, low-energy power system facilities, strengthen the promotion and application of low-carbon, energy-saving and clean production technologies, and support the corresponding policy measures and market-oriented mechanisms to achieve the optimization and adjustment of energy structure and the technological progress of energy supply. [0003] At this stage, in the context of "double carbon", the replacement of traditional energy by a singl...
