Description
Technical field
The present invention relates to a kind of fin tube type adsorption-type solar ice-making system, belong to solar energy heat utilization field.
Background technology
Energy problem is the significant problem that human development faces.Along with the raising of global warming and people's living standard, the demand of the air conditioner refrigerating of comfortableness is constantly increased, this will bring acid test to supply of electric power.And the solar refrigeration technology can effectively be alleviated peak of power consumption power load in period in summer, meets the principle of energy and environment coordinated development.The solar refrigeration technology can be divided into active refrigeration and two aspects of passive type refrigeration, in the world the solar refrigeration Study on Technology is all concentrated active solar energy refrigeration aspect.The active solar energy Refrigeration Technique can be divided into following several kinds again: solar electrical energy generation-electric refrigeration system; The solar steam compression refrigerating system, solar energy absorption type refrigeration, solar adsorption-type refrigerating; Solar steam spray type refrigerating, solar energy evaporation cooling technique and solar energy drying cooling technology.At present, the solar adsorption-type refrigerating technology is also not overripened, and the heat conductivility that is mainly reflected in adsorbent self is lower, and the refrigerating capacity of unit mass adsorbent is less, and the COP of system is lower.
Since the 20 real seventies in century; China just begins to carry out the solar refrigeration Study on Technology; Successively succeeded in developing the solar refrigerating device of various ways; Mainly contain ammonia absorption type refrigeration system, refrigeration system with lithium bromide absorption, calcium chloride-ammonia adsorbent refrigerator, active carbon-methyl alcohol adsorbent refrigerator etc.At present the refrigerating capacity of the every square meter collector area of batch (-type) adsorption refrigeration system every day is between 5-10kg, and COP generally is lower than 0.18, and efficient is lower, has the very big potentiality of improving.Improving aspect the refrigerating efficiency of adsorbent refrigerator, the domestic and international research direction mainly concentrates on the heat and mass transfer performance of improving adsorbent bed, raising system to the collecting efficiency of solar energy, self sensible heat that reduces adsorbent bed, two or many adsorption type continuous refrigeration system and these several respects that reduce cost.Wherein, most critical be exactly optimization to adsorbent bed, Chinese scholars has also proposed a lot of novel adsorbent bed structures: the plate type solar adsorbent refrigerator of the band condensing fin that proposes like people such as A.Boubakri; Liu Zhenyan proposes de cold-tube type solar adsorption-type refrigerating system; The employing transparent honeycomb material that people such as Leiti propose is as the copper pipe adsorption refrigeration system of cover; Vacuum tube adsorption refrigeration system that Xu Yuxiong, Wang Ruzhu etc. propose or the like.
Summary of the invention
The present invention is intended to propose the solar adsorption-type refrigerating technology of a kind of employing active carbon-methyl alcohol that improves the heat and mass transfer performance of adsorbent bed, the vacuum performance that improves system, raising solar energy heating efficient and reduce cost, increase the service life as working medium.
Achievement in research and design experiences with reference to before domestic and international active carbon-methyl alcohol adsorptive refrigeration technology; From the heat transfer property that improves adsorbent bed, the mass-transfer performance that improves adsorbent bed, improve the vacuum anti-pressure ability of adsorbent bed and several respects such as reduce cost are taken all factors into consideration, a kind of brand new solar energy adsorption refrigeration system has been proposed.
The composition of this novel finned tube formula solar adsorption-type refrigerating system: adsorbent bed, Pressure gauge, valve, condenser, evaporimeter, ice build-up tank etc.; Adsorbent bed, condenser, evaporimeter are coupled together, adopt the integrated concentric circles tubular construction of finned inner and outer pipes to adorn active carbon.Whole adsorption tube inner and outer pipes draws through integral type and forms, through being connected as a single entity of fin structure.In adsorption tube, be provided with mass transfer channel.
The operation principle of this novel finned tube formula solar adsorption-type refrigerating system: sunshine incides on the coating for selective absorption on adsorption tube surface, heating adsorption tube surface, and temperature rises, again through the active carbon in fin and the heating tube of tube wall own; Temperature rises, and the methyl alcohol desorption that adsorbs in the active carbon is come out, and through condenser, cooling is condensed into liquid, is stored in evaporimeter at last; Temperature reduces in adsorption tube, and active carbon is strengthened the suction-operated of methyl alcohol, makes the liquid methanol vaporization in the evaporimeter, absorbs a large amount of heat simultaneously, realizes the purpose of refrigeration.
The present invention and existing solar adsorption-type refrigerating compared with techniques have following advantage
1, increased the heat transfer area of adsorbent bed, not only improved absorption efficiency, also improved adsorbent bed self heat transfer property sunshine.
2, be provided with mass transfer channel at the adsorption tube center, improved the mass-transfer efficiency in the adsorbent bed greatly.
3, because adsorption tube adopts tubular structure, improved the vacuum compressive property of adsorbent bed.
