Study on a New Solid Absorption Refrigeration Pair: Active Carbon Fiber—Methanol

Abstract

Our experiments show that active carbon fiber (ACF) might be a good substitute for activated carbon (AC) as the refrigeration capacity Qf and adsorption time of ACF are three times more and 1/5 ∼ 1/10 of those of normal activated carbon (AC), respectively. The COP for ACF-methanol could be 10 percent ∼ 20 percent higher than that of AC-methanol. Thus ACF-methanol might be a good adsorption refrigeration pair for constructing adsorption refrigerators, especially those for household applications.

Performance analysis of a modified two-bed solar-adsorption air-conditioning system

“…The various initial values of parameters (basecase parameters) used in the simulation are mainly adopted from previous experimental results [6,18,19] and are summarized in Table I. The operational conditions in the simulation include condensation/adsorption temperature (301C), evaporation temperature (121C) and ambient temperature (251C).…”

Adsorption cooling cycles for alternative adsorbent/adsorbate pairs working at partial vacuum and pressurized conditions

“…Recently, extensive effort has been put in to investigate the possible adsorption working pairs [6][7][8][9]. The performance of zeolite/water [10], activated carbon/ammonia [11], activated carbon/ methanol [12], and silica gel/water [13][14][15] have been analyzed.…”

Experimental Investigation of Granular Activated Carbon/R-134a Pair for Adsorption Cooling System Applications

“…The adsorption cooling and refrigeration systems have many advantages of being compact, free moving parts, and free of toxic and environmentally harmful materials and need low temperature to work, and don't require synthetic lubrication [5,6]. It is a matter of regret that absorption data are unavailable from the manufactures of adsorbents [7,8].…”

“…It was observed that the coefficient of performance (COP) of icemaker is 0.15. Wang et al [8] studied the adsorption characteristics of ACF/methanol and activated carbon (AC)/methanol pairs. They showed that the coefficient of performance of ACF/methanol pair is about 10 -20 percent higher than that of AC/methanol pair.…”
