Embodiment Construction

[0020] key reference figure 2 and combine figure 1 , a solid adsorption unit tube 24, which is divided into five parts: an adsorption generation section, a condensation section, an evaporation section and two heat insulation sections. A condensation section 37 is in the middle, and a thermal insulation section 39, 40 is provided between the adsorption generation section 36 and the condensation section 37 and between the condensation section and the evaporation section. The thermal insulation section 39, 40 can increase the heat transfer resistance by reducing the small wall thickness or increasing the length. The shell 28 is a circular metal tube. The adsorption generating section is surrounded by an upper sealing plate 34, a lower sealing plate 32, a casing 28 and a cylindrical metal mesh screen 30, and the adsorbent 33 is filled therein, and there are fins 29 in it to enhance heat transfer, and the fins 29 are circular, It is connected with the shell 28 by brazing proces...

Abstract

The invention disclosed solid adsorption unit tube and compound adsorption refrigerating apparatus thereof. The adsorption refrigerating apparatus is composed of adsorbent bed A, adsorbent bed B, condenser and evaporator. The whole adsorption refrigerating apparatus is combined with two adsorption -refrigerating units by heat tube evaporator. Every adsorption unit is composed of multi- solid adsorption unit tubes with independent function. Adsorption section, condensation section and evaporation section separately is in the adsorbent bed, the condenser and the evaporator of the whole adsorption refrigerating apparatus, a heat insulating section is set between the evaporator and the condenser and between the condenser and the adsorbent bed.

Description

technical field [0001] The invention relates to a composite adsorption refrigeration device composed of solid adsorption unit tubes, belonging to the technical field of solid adsorption refrigeration. Background technique [0002] Solid adsorption refrigeration is a refrigeration technology that can be directly driven by heat energy and uses natural refrigerants. Because it has the characteristics of environmental protection and energy saving, it has been generally recognized and accepted at present. [0003] The traditional continuous adsorption refrigeration system includes two adsorbers, one condenser, one evaporator, multiple vacuum valves and system circulating refrigerant, heat medium, and refrigerant connecting pipelines. The system is complex and bulky, and the operating system There are many moving parts, and the sealing and reliability are not ideal. The emergence of solid adsorption unit tube effectively solves the above problems. As a unitary, miniaturized ref...
