Abstract

The invention aims to provide a solar assisted synergistic marine refrigeration system with an ejector and a vortex tube. A solar assisted supercharged refrigerating unit in the refrigeration system makes full use of offshore solar resources for auxiliary refrigeration, and saves the operation energy consumption of the marine refrigeration system; system expansion pressure is recovered by using the ejector, the compressor suction pressure is improved, and the compressor compression ratio is reduced; partial cooling capacity is produced directly by using the vortex tube, so that irreversible loss of a refrigerant in the vapor compression cycle is reduced; compared with the common vapor compression cycle, the system operation efficiency is improved, and the equipment energy consumption is reduced; and an auxiliary refrigerating unit is simple in structure, low in input cost, not easy to damage, stable in operation and good in application prospect.

Description

technical field [0001] The invention relates to a refrigerating cycle system, in particular to a refrigerating system for a solar-assisted efficiency-enhancing ship with an ejector and a vortex tube. Background technique [0002] With the rapid development of the global ocean shipping industry, the technical upgrade cycle of ship power equipment is also accelerating. However, the current marine refrigeration equipment still faces the problem of high energy consumption and low efficiency. According to relevant statistics, worldwide, marine diesel engine emissions account for about 5% to 10% of the air pollution. In the face of the current energy crisis that is gradually increasing and the pollution of the marine environment caused by ship emissions is becoming increasingly serious, how to reduce emissions and reduce environmental pollution from ocean-going ships has become a problem that needs to be further solved in the shipping industry. Therefore, analyzing the problems e...
