Characterization of diethyl ether adsorption on activated carbon using a novel adsorption refrigerator

Adsorption working pairs for adsorption cooling chillers: A review based on adsorption capacity and environmental impact

“…For a higher chilled water outlet temperature of about 16 1C, the cooling power was about 11.0 kW, while the COP increased to 0.43. Compared with that of the former chiller of [26], the COP of this chiller increased by 20%. San et al [29] investigated the performance of a multi-bed adsorption heat pump using SWS-1L which was a selective water sorbent based on calcium chloride (silica gel þ CaCl 2 ) composite adsorbent and water as the working pair, substituted a regular-density silica gel in the adsorbers.…”

“…From the work of [24] it should be remarked that NH 3 is a very toxic gas. From the work of [26] it should be noticed that, diethyl ether is highly flammable gas. It should be noticed from the work of [31] that, ethanol is flammable and has bad effects on nervous system in case of high concentration leakage.…”

“…Their results showed that the maximum adsorption amount of the diethyl ether onto the activated carbon was 2.0028 mg/g at 35 1C and 0.305 atm. From the work of [26] it is pointed out that, diethyl ether is highly flammable gas. Liu et al [27] presented an experimental study on a design for a continuous silica gel-water adsorption chiller (with no refrigerant valves), using low temperature heat source ranging from 70 to 85 1C.…”

“…Their experimental results showed that the maximum adsorption capacity at 25 1C was found to be 0:065 kg H 2 =kg SWCNT at 1.92 MPa, 0:021 kg CH 4 =kg SWCNT at 2.1 MPa, 0:019 kg N 2 =kg SWCNT at 1.92 MPa, 0:042 kg CO =kg SWCNT at 2 MPa and 0:1042 kg CO 2 =kg SWCNT at 1.98 MPa. Al-Ghouti et al [26] built a diethyl ether-activated carbon adsorption refrigerator, which is shown in Fig. 7.…”

Modelling and performance assessment of a two-bed adsorption chiller at different operating conditions

“…[13][14][15][16] Extensive studies are also conducted on the characteristics of new adsorbent/adsorbate pairs. [17][18][19][20][21][22][23] The most used adsorbent in the literature is silica gel, zeolites and activated carbons. Activated carbons are the most effective adsorbent due to large surface area and porosity.…”
