Description
The present invention relates to a kind of solar cold pipe, relate in particular to a kind of integrated compact type low heat loss solar energy cooling pipe, belong to the new energy use technology field.
Solar energy is the abundantest, cleaning and the most promising future source of energy that a kind of mankind can utilize.Significant progress has been obtained in fields such as solar energy heat utilization systematic research, exploitation and productions in countries in the world in recent years.Solar adsorption-type refrigerating is a kind of environmental type Refrigeration Technique, and the research report from this respect is at home and abroad constantly arranged.In current research, the mode that adsorbent bed obtains solar energy mainly contains two kinds: the one, accept to transfer energy to adsorbent bed after the solar radiation by additional solar thermal collector; The 2nd, absorber is made flat box type, its outer metallic plate is as the baffle of plate solar collector.System architecture is comparatively complicated, the cost height, and leak easily.Utility model patent: ZL93243569.6 " monomer absorption refrigeration pipe " has proposed a kind of monomer absorption refrigeration pipe of being made up of adsorbent bed section, condenser section and evaporimeter section three parts, Liu Zhenyan, Lu Yunzhuang, Zhao Jiaxin, " Zeolite-active carboncompound adsorbent and its use in adsorption solar cooling tube " (Solar EnergyMaterials and Solar Cells, 1998, Vol.52:45-53) inquired into the application of this monomer absorption refrigeration pipe in solar refrigeration.But this monomer absorption refrigeration pipe is not high to the collecting efficiency of solar energy, and the thermal-arrest equilibrium temperature is low, and structure is compact inadequately, remains further to be improved.
The object of the present invention is to provide the cold pipe of high-efficiency solar of a kind of environmentally safe, movement-less part.This cold pipe self is finished to the efficient absorption of solar energy and to the external world cold is provided, and also can freeze under the lower situation at sunshine, and is simple in structure, easy to operate, is easy to industrialization.
For realizing such purpose, the solar cold pipe of the present invention's design is made up of adsorbent bed and condensation/vaporization device two parts, this two-part axis can have an angle, there is a steam channel at the center of adsorbent bed, the outside of adsorbent bed is a double-layer coaxial high-boron-silicon glass pipe, the inner cylindrical block adsorbent that loads the road of being made by adsorbent powder or particle with holes.Two interlayers are the vacuum heat-insulation interlayer, and inner tube outer surface scribbles solar selective coat, arrange cold-producing medium to be housed snakelike spiral coil in the condensation/vaporization device.
Operation principle of the present invention is: daytime, adsorbent bed absorbed solar energy and the temperature rising, and refrigerant vapour is come out by desorption from adsorbent bed, and system's internal pressure rises.Circulation cooling heat transferring fluid in this moment spiral coil, when system pressure reached the saturation pressure corresponding with condensation temperature, refrigerant vapour was condensed into liquid and is stored in the condensation/vaporization device at the spiral coil outer surface.This heating desorption process proceeded to about 3: 30 afternoon.At dusk, the adsorbent bed temperature begins to reduce, and the cold-producing medium in adsorption condensing/evaporimeter gradually, the cold that the cold-producing medium evaporation produces are transported to by the heat exchanging liquid in the spiral coil that regenerator is stored or direct external cooling.
The present invention is in conjunction with the solar vacuum heat-collecting pipe technology, improve the effective absorption of adsorbent bed to solar energy, the solar cold pipe that provides in summer when fine the heat-collecting temperature of adsorbent bed can reach more than 90 ℃, the gross energy conversion efficiency ratio of incident solar energy (cold of generation with) is about 0.13, has overcome the shortcoming that traditional solar powered adsorption refrigeration can not freeze at the lower weather of insolation.The present invention effectively utilizes clean solar, and process of refrigerastion is pollution-free fully, and is simple in structure, and the operation operation is convenient, is expected to make China's solar adsorption-type refrigerating to enter practicability, is producing good economic and social benefit aspect energy savings, the protection environment.
