The beneficial effects of the utility model: the mechanism of the utility model utilization vaporation-type refrigeration and absorption type refrigerating, utilize solar energy to realize refrigeration to refrigerating box whole day at night on daytime, material is easy to get simultaneously, and is simple in structure.Topmost characteristics are to need not electricity consumption in the use, only in night and a small amount of electricity consumption of rainy weather, can not discharge the material that environment structure is threatened, and have really accomplished few electric environmental protection.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a composition structural representation of the present utility model;
Fig. 2 is an adsorbent bed part-structure schematic diagram of the present utility model;
Fig. 3 is a sandwich portion structural representation of the present utility model.
The specific embodiment
Referring to figs. 1 through Fig. 3, a kind of solar adsorbing type refrigerator of the present utility model, comprise the outer case 1 that has some apertures 11 on the outer wall, be with the internal box 2 of band loam cake 21 in the described outer case 1, be filled with water imbibition filler 4 between the interlayer 3 that forms between described outer case 1 and the internal box 2, described filler 4 tops be provided with can water filling in it water filling port 5; Also be provided with a liquid reservoir 6 of being close to internal box 2 tank walls in the described outer case 1, described liquid reservoir 6 is by circulating line 61,62 are connected with and can place outdoor adsorbent bed 7, are coated with adsorbent on the described adsorbent bed 7, and described adsorbent bed 7 bottoms also are provided with electric boiling plate 8.Wherein, described liquid reservoir 6 can be regarded an evaporimeter as, is used to store the suction cryogen that comes out from the adsorbent bed desorption.
The refrigeration modes of the utility model adsorbing type refrigerator has two kinds, is respectively sweat cooling and absorption refrigeration.Its mechanism is respectively:
1, sweat cooling
Use the water filling port 11 that passes through outer case 1 toward interlayers 3 interior water-fillings, make to have absorptive filler 4 suctions and radially expansion.After filling with water, the article of in internal box 2, packing into and will refrigerate, under the hot weather, temperature raises, and the immersion interlayer 3 in the device heats up, and causes wherein moisture by outer, internal box 1, interlayer 3 and aperture 11 between 2 evaporate away, take away the heat in the internal box 2, make internal box 2 inner spaces maintain lower temperature, thereby reach the cryogenic temperature purpose that keeps adsorbent bed 1 to make.
2, absorption refrigeration
It is right that the adsorbent that the utility model preferably adopts is that active carbon-methyl alcohol or molecular sieve-water follow absorption refrigeration working medium.By day, adsorbent bed 7 is risen by the solar radiation temperature, cold-producing medium (methyl alcohol or water) steam desorption and going out from adsorbent (active carbon or molecular sieve), warp and extraneous air heat exchange, emit heat and be condensed into liquid refrigerant, flow into the liquid reservoir 6 that is close on internal box 2 tank walls by circulating line 61 or 62.To night, adsorbent bed 7 temperature descend, pressure also descends, and adsorbent (active carbon or molecular sieve) will absorb moisture, and the cold-producing medium in the liquid reservoir 6 (methyl alcohol or water) becomes the gas rising by liquid and is adsorbed bed 7 absorptions again through circulating line 62 or 61, in this process, the cold-producing medium evaporation has absorbed the heat in the internal box 1, and during second day daytime, said process is proceeded, so move in circles, thereby realize cooling purpose.The utility model refrigerating box need be used electrical heating when overcast and rainy work, all the other all not electricity consumptions of situation.
Beginning refrigeration by absorption type, mainly is evening refrigeration, daytime the vaporation-type auxiliary temperature-reducing, and the scattering and disappearing of the last late refrigerating capacity of absorption type that slows down finished a cyclic process daytime at night.
In conjunction with Fig. 2, wherein, described adsorbent bed bottom is provided with row's adsorbent bed fin 9, outwards emits heat when being used for adsorbent bed 7 desorptions.
Be provided with the pipeline fin 10 that is used to dispel the heat between the described circulating line 61,62, be beneficial to refrigerator steam and surrounding air and carry out heat exchange rapidly.
In addition, as preferably, described filler 4 has three layers, is respectively heat transfer layer, water storage layer and evaporation layer from inside to outside.By being respectively special polyester fiber (better contact and realize better heat transfer property), Lanseal fiber (preserving most water), ion exchange resin (control evaporation of water speed) outside the lining with inner pressurd vessel.In the weather of sweltering heat, temperature on every side heats up the material of this humidity, and the dividing potential drop of the steam of interlayer 3 impels steam to evaporate greater than the dividing potential drop of the steam of surrounding air.
As preferably, described aperture 11 is a circular hole, be convenient to make, and good looking appearance.
In addition, take into account the intensity and the heat transfer efficiency of casing, the thickness of described internal box 1 is preferably 0.3cm-0.5cm.
And whole solar adsorbing type refrigerator length and width height roughly is respectively 100cm, 65cm and 175cm.And the loam cake on the internal box 2 21 is elected a sliding door as, and is extremely easy to use.
The mechanism of the utility model utilization vaporation-type refrigeration and absorption type refrigerating utilizes solar energy to realize refrigeration to refrigerating box whole day at night on daytime, and material is easy to get simultaneously, and is simple in structure.Topmost characteristics are to need not electricity consumption in the use, only in night and a small amount of electricity consumption of rainy weather, can not discharge the material that environment structure is threatened, and have really accomplished few electric environmental protection.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
