Problems solved by technology

However, in practice, the rapid heat collection in the desorption stage and the rapid heat dissipation in the adsorption stage, good heat conduction and mass transfer are often two pairs of contradictions that are difficult to coordinate well, especially the former, so far there is no adsorption heat collection bed structure that can well meet the requirements
Judging from the structures of adsorption heat-collecting beds currently used by researchers in various countries, the flat plate-type adsorption heat-collecting bed is the most used and is an ideal structure. Higher
The problems that need to be solved in this high-performance heat collection method are mainly the difficulty of heat dissipation during the adsorption of the adsorption heat collection bed and the inhomogeneity of heating and cooling of the adsorbent.

Embodiment Construction

[0016] The structure of the vacuum tube adsorption heat collecting bed of the present invention will be further described below in conjunction with FIG. 1 . The adsorption heat collection bed is a double-layer vacuum glass casing 4, the casing interlayer is vacuum, and the solid adsorbent is filled in the inner tube. The mass transfer channel 5 is installed in the middle of the adsorbent, and the micropores on the mass transfer channel are used to strengthen the mass transfer. , the natural pore space of the adsorbent can also function as a mass transfer channel. A cooling water pipe 1 is installed in the inner tube of the vacuum tube, and the water pipe is provided with a heat absorbing belt 3, and a strip support 2 is arranged in the inner pipe to fix the cooling water pipe 1 and the heat absorbing belt 3. A special metal cover seals the vacuum tube, and the mass transfer channel and the cooling water pipe pass through the cover and are welded and sealed with the cover. Thi...

Description

Technical field [0001] The invention relates to a daytime continuous solar adsorption refrigeration system, which belongs to the technical field of solar adsorption refrigeration Background technique [0002] The solar adsorption refrigerator is mainly composed of an adsorber / generator, a condenser, an evaporator, a throttle valve, a solenoid valve, and a liquid receiver. During the day, the solar energy heats the adsorption heat-collecting bed to desorb the adsorption heat-collecting bed. The desorbed refrigerant is cooled in the condenser and stored in the liquid receiver; at night, the adsorption heat-collecting bed is cooled and has adsorption capacity. At this time, open Throttle valve, the refrigerant evaporates and cools in the evaporator, turns into steam and is adsorbed by the adsorption heat-collecting bed until the adsorption heat-collecting bed reaches adsorption saturation. The cycle refrigeration process is completed repeatedly in this way. Therefore, the cur...
