An indirect evaporative cooling system combining with thermoelectric technology (i.e., TIEC system) is proposed, in which a counter-flow plate-fin cooler inserted TEC) modules. In hot and humid climate, condensation may occur on the dry channel surface of cooler. For system, aid TEC technology, temperature can be much lower than that traditional cooler, thus, from primary air more likely to tak...

We have developed a technique for the printing of fine copper lines using solutions of a metal organic precursor, copper hexanoate (CuHex). Liquid ribbons 500 μm wide, deposited on a glass substrate either by ink-jetting or capillary writing, are observed to split into two or four finer lines depending on the solution concentration. Surface profiles indicate that the thickness, width and number...

Table 1. Standard air density as a function of elevation above sea level (at 70F and 50% relative humidity). M echanical ventilation can be divided into three types: negative-, positive-, and neutral-pressure ventilation. Negativepressure systems use fans to exhaust air, thereby creating a slight partial vacuum that draws fresh air in from outdoors. Negative-pressure ventilation systems are use...
