Daily fresh water production from Malaysia’s urban atmosphere using 6 thermoelectric cooling units

Abstract Extracting fresh water from Malaysia’s atmosphere which stores a wealth of can be conducted via the air condensation. In this study, miniature atmospheric generator (AWG) system named Mini-AWG was designed and constructed using 6 thermoelectric cooler (TEC) units, mesh-shaped filter ventilation fan. Subsequently, experimented for several days under outdoor climate at River Engineering Urban Drainage Research Centre (REDAC) in Universiti Sains Malaysia (USM) is located urban area Nibong Tebal. The objectives work are to develop AWG TEC units generate by vacuuming into system, determine impacts humidity rates ambient temperatures values on quantity production analyze quality generated system. daily percentages relative humidity, volume produced were measured resulted that hourly amount proportional though they had inverse relationship with temperatures. maximum 0.355 litres experimentally 12 hour-period day. According various ranged between least 46% peak 75% morning night, an equation y= 1.3136x + 16.936 R 2 0.8901 attained project Mini-AWG, where Y X designated as percentage production, respectively. examined parameters compliance World Health Organization (WHO) class I drinking standards.
