Description
Technical field
The utility model relates to a kind of device of technical field of solar utilization technique, specifically is a kind of Adsorption Cold Storage refrigerator based on industrial exhaust heat or Driven by Solar Energy.
Background technology
Along with energy crisis globalization, development cold-storage or heat storage technology are adjusted the imbalance between supply and demand of the energy on time and space, alleviate power supply pressure, and the efficient and rational low-grade heat source that utilizes will be a main direction of refrigeration air-conditioner and heat pump industry development from now on.Nowadays, refrigerator has been one of requisite electrical equipment in the life, still " free-floride " refrigerator, reduce running noises, reduce power consumption or the like, remain the professional and endeavour the problem that will solve.According to statistics, a large amount of electric power of refrigeration plant consumption such as refrigerator and air conditioner account for 10～20% of national total electricity consumption, add inconvenience that summer, peak of power consumption was brought and electricity price and raise, and all make using electricity wisely become one of focal issue that ordinary people pays close attention to the most.On the other hand, present in-depth along with China market economic construction, China's food production has had great development, yet the food transport particularly year amount of loss of the Refrigerated Transport of quick-frozen food reaches hundred billion yuan, and about according to statistics 90% meat, 80% aquatic products, a large amount of milk and bean product still transport under the situation that does not have Refrigerated Transport to guarantee basically.Still be in the bigger market pressure of China's refrigerator car industry faces of initial stage developing stage.
Mechanical refrigeration formula refrigerator car is China deepfreeze car owner stream, although mechanical refrigeration unit technology maturation, reliable, off design performance is stable, but still there are many defectives, as: (or individual motor drives to need power drive, or drive by automobile engine), easily freon leakage etc. takes place, and mostly adopt the import refrigeration unit therefore to cut apart huge profit.Cold drawing refrigerator car, liquid nitrogen spraying refrigerator car, liquid CO
2All comply with country to environmental protection requirement with dry ice refrigerator car technology, but because factors such as operating cost and recondition expense, remarkable effect is not seen in these technological achievement transformations, cold drawing refrigerator car vehicle's center of gravity height not only wherein, refrigeration system shock resistance, vibration ability are poor, and are subjected to the restriction of ground freezing station or charging station and power supply mode.Now also existing documents and materials have been reported the result of study that absorption, the physical absorption that can utilize that waste heat drives and chemisorbed formula cold accumulation system that some are traditional are carried out, but because the existence of liquid refrigerant all can be arranged in these cold-storage devices, so if device is toppled over crooked or high vibration jolts, often have the phenomenon generation that liquid flows backwards, thereby influenced the system works performance greatly, reduce refrigerating efficiency, sometimes even have to a certain degree a potential safety hazard.
Find through retrieval prior art, existing absorption refrigeration or cold-storage apparatus majority concentrate in the application of physical absorption, promptly utilize silica gel-water or zeolite-water etc. as the right aircondition of working medium, can not reach the requirement of subzero refrigeration with water as the system of cold-producing medium.Ammonia is a kind of environmental protection cold-producing medium that cryogenic temperature is lower than 0 ℃ that can be used for, and has and studies have shown that the absorption property of physical absorption ammonia is far below chemisorbed ammonia.Lee etc. research and develop calcium chloride-ammonification absorbing refrigeration system, but because the existence of liquid ammonia is arranged in the condensation/vaporization device, make its refrigeration system be restricted in application.
The utility model content
The utility model is at the prior art above shortcomings, a kind of Adsorption Cold Storage refrigerator based on industrial exhaust heat or Driven by Solar Energy is provided, the heat of desorption absorption refrigeration technology that adopts the no liquid cold-producing medium to exist, and connect by the adsorbent beds of two groups of different absorption salt and to combine, not only improved the theoretical refrigerating capacity of system, but also improved its anti-vibration ability of jolting, thereby enlarged the device range of application, wherein one group of adsorbent bed is put and ways of connecting, make cold-storage device reach two warm areas, promptly 5-6 ℃ and-refrigeration of 15-0 ℃.Simultaneously, the outer member of the adsorbent bed of another group is optimized design, it is incubated or the effect of ventilation heat exchange preferably at different working stages, thereby improved the service behaviour of system greatly.

Fit tightly the metallic plate that is provided with a horizontal positioned on the low thermohaline adsorbent bed of described freeze space;
The outside of described high temp. salt adsorbent bed is provided with a sleeve, is the insulation air between sleeve and the high temp. salt adsorbent bed.
The outer wall of described high temp. salt adsorbent bed is evenly equipped with the straight rib of rectangle to improve the heat exchange effect that free convection is vertically ventilated;
Described high temp. salt adsorbent bed and low thermohaline adsorbent bed are cylindrical structural and inner high temp. salt adsorbent or the low thermohaline adsorbent that is filled with corresponding high temp. salt or low thermohaline and the generation of expanded graphite composite curing respectively; The manufacture craft of this adsorbent is the expanded graphite that earlier the expansible graphite high-temperature process is become myrmekitic texture, again expanded graphite and high temp. salt or low thermohaline are fully mixed according to the certain mass ratio, at last with the mixture oven dry afterwards briquetting make compound adsorbent.
Following reversible chemical reaction can take place with ammonia respectively in described high temp. salt adsorbent and low thermohaline adsorbent, because under identical pressure condition, the equilibrium temperature that high temp. salt and ammonia carry out chemical reaction is higher than the equilibrium temperature of hanging down thermohaline and ammonia react, therefore be referred to as high temp. salt and low thermohaline respectively, specifically comprise: different types of alkaline earth salt, transition metal salt, halide, sulfate, nitrate or phosphate.
