Background technology
Traditional refrigeration modes mainly is the freon steam compression type refrigeration that electric energy drives.But owing to destruction and the greenhouse effects of cold-producing medium to ozone layer, and the influence of electric power breach, the refrigeration system (as absorption refrigeration, spray type refrigerating etc.) that is driven by thermal source causes people's attention day by day.The refrigeration system that these thermals source drive can use used heat, solar energy, combustion gas as the energy, thereby can significantly reduce the consumption of electric energy.But the absorption system complex structure, volume ratio is huger, and along with the increase of running time, the systematic working medium performance descends, adsorption refrigeration system can't be freezed by day simultaneously, only could freeze at night, therefore can not satisfy people's requirement of high temperature period needs refrigeration by day; Compare with it, the injection refrigerating system moving component is few, and system is changeable, is suitable for various operating modes, so ejector refrigeration has worldwide caused the attention of people's height at present.In injection refrigerating system, injector has played the effect of compressed refrigerant vapor, and it is the core component of injection refrigerating system.Working fluid (high pressure refrigerant vapor) is accelerated into (supersonic speed) injection stream at a high speed through contraction and enlargement nozzle, produce low pressure at suction chamber, after driving fluid enters the suction chamber of injector, under the effect of carrying secretly of working fluid, quicken, two fluid streams form the single and uniform fluid-mixing gradually at mixer, slowing down through diffuser boosts to certain back pressure again, enters condenser condenses.By the operation principle of injector as can be seen, it needs electric energy drive compression machine Compressed Gas unlike traditional compression refrigeration, but by high steam as power.The single energy of general in the prior art use drives the heating and cooling agent as thermal source, as uses solar thermal collector, when solar radiation is sufficient, can save a large amount of energy, and reaches good refrigeration, but when solar radiation is not enough, refrigeration system can't be worked.Therefore reach continuously, the high efficiency refrigeration is the key of injection refrigerating system.
The utility model content
For overcoming above-mentioned shortcoming, the utility model proposes a kind of novel solar gas-injection refrigerating system.The utility model combines solar thermal collector, combustion gas and injection refrigerating system, and when solar radiation met the demands, the hot water that provides by solar thermal collector came the heating and cooling agent as thermal source; When solar radiation is not enough, can satisfy the requirement of generator again by the auxiliary heating of combustion gas.In this way, the electric energy that can only consume minute quantity just reaches the refrigeration identical with compression refrigeration.
A kind of novel solar gas-injection refrigerating system, comprise solar thermal collector, steam generator, water pump, injector, evaporimeter, condenser, choke valve, working medium pump, refrigerant water pipe, combustion heater, temperature controller and pipeline, be characterized in: the solar thermal collector outlet is connected with steam generator, water pump, solar thermal collector import successively through pipeline, forms to add hot water circulating device; The outlet of steam generator is connected with the working steam import of injector through pipeline, and evaporimeter is connected with the refrigerant water pipe, and the outlet of evaporimeter is connected with the jetting steam caused import of injector through pipeline, and the injector outlet is connected to condenser.The outlet of condenser then is connected on the choke valve.Working medium one tunnel after the throttling connects generator through the working medium delivery side of pump, and another road connects evaporimeter through pipeline.
Also connect a combustion heater on the steam generator, by the temperature controller control that is connected in the steam generator, heater outlet is connected with steam generator, water pump, heater import successively through pipeline, forms another and adds hot water circulating device.
Add hot water circulating device and be at least a cover, when overlapping more with can connect being connected of steam generator also can be in parallel.
The refrigeration system of the utility model design, simple in structure, easy to operate, economical and practical, adaptability extensively, good refrigeration effect, when solar radiation is sufficient, can save a large amount of energy, when solar radiation is not enough, can utilize combustion heater to replenish the energy, reach refrigeration effect of sustainable high efficiency.
