Abstract

The invention belongs to the technical field of efficient conversion of low-grade heat sources, and provides a solar-assisted ocean temperature difference energy based cooling, heating, power and fresh water poly-generation system. By means of the system, ocean surface warm seawater subjected to solar heat collection is used as a heat source to heat and vaporize a low-boiling-point working medium discharged from a working medium pump, and meanwhile the seawater subjected to heat exchange enters a single-pole flash tank to be subjected to flash evaporation to generate fresh water. The vaporized working medium enters an expansion machine to do work, dead steam exhausted from the expansion machine enters a flow divider, the flow divider divides the dead steam into two paths, and one path provides heat for working fluid of an ejector in an ejection refrigeration sub-cycle; and the other path provides heat for a working medium in a steam compression heat pump sub-cycle, so that after the working medium is vaporized and enters a compressor, the temperature rises to supply heat to the outside. The two paths of working media subjected to heat exchange enter a mixer to be mixed and enter a generator again after being pressurized by the working medium pump to achieve reciprocating circulation. Recycling of low-grade heat energy based on solar-assisted ocean temperature difference energy is achieved, and electric energy, cold energy, heat and fresh water can be output at the same time.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency conversion of low-grade heat sources, and specifically relates to a solar energy-assisted ocean temperature difference energy cooling, heating and power generation system and a freshwater polygeneration system, which is a system that utilizes solar energy and ocean temperature difference energy for power generation, refrigeration, heating and seawater Diluted circulatory system. Background technique [0002] With the rapid development of the economy, the demand for energy is becoming more and more urgent. I consume a lot of energy every year, of which fossil energy accounts for 92% of the total. Among these fossil energy sources, coal accounts for more than 70% of the total. With the mineral energy reserves on the verge of depletion and the serious environmental hazards caused by their utilization, we urgently need to develop renewable energy sources such as solar energy and ocean tempera...
