Embodiment Construction

[0016] Provide specific embodiments in conjunction with the content of the material of the present invention:

[0017] For adsorption air conditioning conditions, examples of bulk mixed adsorbents are as follows:

[0018] (1) Calcium chloride 70%, expanded graphite 30%, the two are directly mixed and then dried. For pure calcium chloride, due to the phenomenon of expansion and agglomeration in the adsorption process, the necessary expansion space must be left. It has been verified by experiments that the maximum volume filling of calcium chloride is only 41.6% in the air-conditioning working condition. Using the above mixed adsorbent formula, since the expanded graphite can improve the mass transfer of the adsorbent, the volume filling capacity of calcium chloride can be increased by 29%, and the corresponding volume cooling capacity will also be increased by 29%.

[0019] (2) Calcium chloride 8% 0, expanded graphite 20%, the expanded graphite is impregnated in the aqueous s...

Abstract

A mixed adsorbent for the absorption bed of air conditioner is prepared from calcium chloride and expanded graphite in the weight ratio of (60-80%):(20-40%) for the bulk one or (55.1-67.7%):(17.2-32.7%) for the solid one. Its advantages are high gas osmosis, high heat conductivity and high refrigerating efficiency.

Description

technical field [0001] The invention relates to an adsorbent in an adsorption refrigeration / heat pump system, in particular to a calcium chloride-expanded graphite mixed adsorbent. Used in the field of adsorption refrigeration. Background technique [0002] As a green refrigeration technology driven by renewable energy or low-grade waste heat, adsorption refrigeration / heat pump technology has attracted more and more attention. The adsorbents currently used in adsorption refrigeration / heat pump systems mainly include physical adsorbents, chemical adsorbents, and physical-chemical mixed adsorbents. Compared with physical adsorbents, chemical adsorbents have the advantages of large adsorption and desorption capacity, high cooling and heating power, etc., but also have disadvantages such as poor heat transfer, poor gas permeability, and serious expansion. In order to solve the problem of chemical adsorbents Due to these shortcomings, the research on mixed adsorbents has become...
