ARTICLE IN PRESS 428 R.Z. Wang, R.G. Oliveira / Progress in Energy and Combustion Science 32 (2006) 424–458 Fig. 3. Solar-powered icemaker without valves: (1) cover plate; (2) adsorbent bed; (3) insulation; (4) condenser; (5) evaporator; (6) water tank; (7) cold box [63]. Another adsorption icemaker with the pair activated carbon–methanol, was tested in Burkina Faso by Buchter et al. [65]. The results of this prototype were compared to those obtained by Boubakri et al. [66,67] in Morocco, with a similar system, which was commercially produced in the 1980s by the French company BLM. The main difference between those systems is the presence of ventilation dampers in the former (seen in Fig. 4), which were open during the night to improve the cooling of the adsorbent bed. The machine tested in Burkina Faso presented a cooling performance about 35% higher than the machine tested in Morocco. The COP of the former machine ranged from 0.09 to 0.13 when the insolation ranged from 22 to 25 MJ m2. In this system, ice produced during the adsorption time was not removed from the cold box, and it was used to maintain the box at about 5 1C during the daytime. Hildbrand et al. [68] developed an adsorption icemaker in which water was used as refrigerant and ice was produced within the evaporator. The adsorbent was silica gel and the total solar collector area was 2m2. The scheme of this machine is presented in Fig. 5. The experiments were carried out over a period of 68 days and showed the considerable influence of the environmental condi- tions (insolation and outdoor temperature) on the performance of the system. For insolation higher than 20 MJ m2, the COP was between 0.12 and 0.23; when the mean outdoor temperature was Fig. 4.

COPs higher than 0.15 were generally obtained with outdoor temperatures below 20 1C.PDF Image | Adsorption refrigeration

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
