Abstract
The utility model relates to a concentric cylinder. A cooling water pipe is positioned on the shaft center line of the cylinder. The outermost layer of the concentric cylinder is provided with a glass pipe, and a second layer is an inner cylinder layer. An adsorbent layer is arranged between the inner cylinder layer and the cooling water pipe. Both ends are respectively provided with an upper cover plate with a refrigerant inlet and a lower cover plate with a refrigerant outlet which are in sintering or other sealing connection with the inner cylinder layer. The inner part of the adsorbent layer is provided with an adsorbent layer and gaps used as a mass transferring path.
Description
The utility model relates to a kind of solar adsorber, especially a kind of solar airconditioning glass tube with vacuum solar adsorber belongs to heliotechnics and refrigeration technology field in the mechanical engineering.
Adsorption refrigeration system of the prior art is mainly by absorber, formations such as condenser, heat collector and evaporimeter.Wherein absorber is the core component of this system, the stacking bed formula structure of the many employings of solar energy absorber, mainly the adsorbent bed of being piled into by the adsorbent with high porosity, glass cover, thermal protection structure etc. constitute, and the micropore gap in the adsorbent has constituted mass transfer channel.Adsorbent bed receives solar radiation daytime, and temperature raises, and resolves cold-producing medium, and evening, environment temperature reduced, and adsorbent bed reduces by radiating mode temperature such as radiation and convections, and the agent of beginning absorption refrigeration produces refrigeration.Produce heat of adsorption in the adsorption process.The generation of heat of adsorption raises adsorbent temperature, is unfavorable for the carrying out of adsorption process.The absorber of prior art relies on the nature type of cooling, owing to can not fully take away heat of adsorption, thereby adsorbent temperature is higher when causing absorption, in addition, although adopt the glass cover to reduce the radiation loss of adsorbent bed, because the heat convection effect between adsorption plane and the glass surface, the heat loss of adsorbent bed is still considerable, thereby has limited the resolution temperature raising greatly.
The purpose of this utility model is to overcome deficiency of the prior art, utilizes the high characteristics of glass tube with vacuum heat-collecting temperature, and a kind of solar airconditioning glass tube with vacuum solar adsorber is provided.
The technical solution of the utility model is as follows: can fully absorb solar energy when adsorbent is resolved, prevent the heat loss through convection loss by vacuum structure; When absorption, take away heat of adsorption by logical cooling water in the water pipe that passes through from the adsorption layer center, produce refrigeration, cooling water heating rear-service department can provide warm water to the user.The utility model is the concentric circles tubular, cooling water pipe is positioned on the cylinder axial line, outermost layer is a glass tube, second layer inner drum layer, be adsorbent layer between inner drum layer and the cooling water pipe, two ends are respectively upper cover plate that has refrigerant inlet and the lower cover that has refrigerant outlet, and upper cover plate and lower cover and inner drum layer sintering or other sealed attachment form, establish absorbent particles in the adsorbent layer, and to leave the gap be mass transfer channel.It between glass tube and inner drum layer vacuum layer.The inner drum layer surface can be coated with the selective coating that increases absorptivity, and perhaps inner drum layer adopts glass to make.Good by the inner drum layer thermal conductivity like this, specific heat is materials with smaller also, has increased the effect of absorptivity.Heat of adsorption is taken away in the cooling water pipe water flowing, becomes warm water and uses for the user.When adsorbent was resolved, emptying (not water flowing) in the pipeline was if the solar radiation deficiency then helps to resolve toward the interior logical hot water by the auxiliary thermal source heating of pipeline; Logical cooling water is taken away heat of adsorption during absorption becomes warm water for using.During practical application, whole absorbing cylinder is installed in one to have above the support of parabolic type reflecting surface.Some absorbing cylinders link by the collection case can form absorber.Many glass tube with vacuums are formed solar adsorber, join together by water manifold, cold-producing medium header etc., linking with parts such as condenser, evaporimeters constitutes solar energy solid absorption refrigeration/air-conditioning system again.
The utlity model has very strong practical value; help protecting environment; adopt the solar air-conditioner system of glass tube with vacuum solar adsorber; under day, irradiation intensity was 600 watts, the condition at 8 hours sunshine; unit square rice heat collector surface heat-collecting temperature can reach about 150 ℃; realize about 150 watts of refrigeration work consumption, obvious improvement has been arranged than conventional solar energy solid absorbing refrigeration system performance.
Further describe below in conjunction with accompanying drawing:
