Power generation and refrigeration combined cycle system based on ocean temperature difference energy

Abstract

The invention belongs to the technical field of cogeneration of cold and power, and relates to a power generation and refrigeration combined cycle system based on ocean temperature difference energy.According to the power generation and refrigeration combined cycle system based on THE ocean temperature difference energy, sea surface layer temperature sea water is used as a main heat source to heat and vaporize a low-boiling-point working medium from a mixer, the vaporized working medium enters an expansion machine and pushes the expansion machine to do work, the expansion machine provides mechanical energy for a power generator and a compressor, dead gas discharged from the expansion machine is condensed into a liquid state in a condenser by deep layer cold sea water and flows into a shunt, the shunt divides the liquid state working medium into two paths, one path is pressurized by a working medium pump and then flows into the mixer, the other path of the working medium enters an evaporator to absorb heat after being depressurized by an expansion valve, so that a cold storage obtains cold energy, the working medium coming out of the evaporator enters the compressor to be compressed and then flows into the mixer to be mixed with the working medium flowing in from the working medium pump, and the working medium coming out of the mixer enters a generator to complete a primary circulation process. The system realizes full utilization of the ocean temperature difference energy and can simultaneously output electric energy and the cold energy.

Description

technical field [0001] The invention belongs to the technical field of cogeneration of cold and electricity, and relates to a combined cycle system for power generation and refrigeration based on ocean temperature difference energy, which is a cycle system for generating power and cooling by using ocean temperature difference energy. Background technique [0002] Traditional fossil fuels such as coal, oil and natural gas, as non-renewable energy sources, will eventually be exhausted with the continuous exploitation of human beings. With the continuous consumption of fossil energy, global temperature rise, air pollution and environmental changes, etc. The problem is not uncommon. There are extremely rich renewable energy resources in the ocean. Ocean energy has many advantages such as non-polluting and recyclable. Most of the solar radiation reaching the earth's surface is absorbed by the seawater on the earth's surface, so the inexhaustible solar energy is stored on the sur...

Problems solved by technology

Although the ocean temperature difference energy power generation cycle based on the organic Rankine cycle has the advantages of simple equipment and convenient maintenance, but its thermal efficiency is low, so the market competitiveness of this technology is not enough, and it has been difficult to achieve commercialization.
