A mechanical and experimental study on the heat loss of solar evacuated tube

The experimental system of heat loss of all-glass evacuated solar collector tubes (evacuated tube) is firstly designed and constructed, which uses electric heater as thermal resource. The equilibrium temperatures are less than ±1℃ during the test, and the temperature differences of up/middle/low node in the tube are less than 1 ℃, 3 ℃, and 7℃ respectively. The heat loss of evacuated tube increases about 2.7% with vacuum state of 0.01-1 mPa, and it has the best performance at tube temperature of 20-280℃. The invalidation tube (> 200 mPa) has the biggest heat loss that increases linearly with the tube temperature. The evacuated tubes with the vacuum of 0.01-1 mPa are suitable for most solar adsorption refrigeration.

Adsorption models and structural characterization for activated carbon fibers

The nitrogen adsorption isotherms at 77.69 K were measured for two samples of activated carbon fibers and their microstructures were investigated. Among established isotherm equations, the Dubinin-Radushkevich equation showed the best agreement with the experimental data, while the Langmuir equation showed a large deviation when employed at low relative pressures. The MP method, t-method and αs-method were used to analyze the pore size distribution. The calculated average pore widths and BET (Brunauer-Emmett-Teller) surface areas for the sample A-13 were 0.86 nm and 1 286.60 m2/g, while for the sample A-16, they were 0.82 nm and 1 490.64 m2/g. The sample with larger pore width was more suitable to be used as additive in chemical heat pumps, while the other one could be used as adsorbent in adsorption refrigeration systems.

车与心愿--黄色小精灵LF50QT-2A

“如果用一种颜色来形容我，你会用下面哪种颜色：橙、蓝、白、红、绿、粉、紫、黄。”“黄色!”“为什么?”“因为我知道：橙色是值得交往的人，蓝色是你爱的人。白色是心灵深处的人．红色是你憎恨的人，绿色是偶尔想起的人，紫色是最可靠的人。黄色是不会忘记的人。”她说道。
