Calcium chloride-active carbon mixed adsorbent

Abstract

The invention is a calcium chloride-active carbon compound sorbent. The sorbent can be divided into bulk and solid. The component and weight percentage of the sorbent with bulk type is: calcium chloride 60%-78%, active carbon 22%-40, the solid sorbent: calcium chloride 49%-60.2%, active carbon 17.2-32.7%, water 12.2%-15.1%, cement 6.1%-7.5%. The invention uses active carbon as base material, it upgrades the gas penetration performance and its volume filling quantity greatly. At the same time, because the filling density is large, it improves the heat conducting performance of the sorbent.

Description

technical field

[0001] The invention relates to an adsorbent used in an adsorption refrigeration / heat pump system, in particular to a calcium chloride-activated carbon 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 be...
