Air Conditioning and Heat-related Mortality

Fully Fresh Air Air-conditioning System Equipped with Double Heat Pipe Based Heat Recovery Technology

The using of double heat pipe based heat exchanger (HPHX) in a conventional fully fresh air air-conditioning (AC) system was examined in the present study. The fabricated HPHXs were tested under the actual conditions and the measured data were used to study the performance of the existing AC system (System A) and AC system equipped with the double HPHX (System B) for a yearly operation through ...

Passive Energy Air-to-Water Heat Pipe Based Heat Exchanger and its Potential of Air Pre-cooling in Air Conditioning Systems for Iran Climate

Air pre-cooling equipment is normally being employed in air-conditioning systems for pre-cooling the ambient outdoor air to enhance the air-conditioning systems performance. In this study, the potential of a passive water-to-air heat pipe based heat exchanger (HPHEX) for air pre-cooling purpose in air-conditioning systems for the high cooling load demanding regions of Iran was investigated. To ...

[Perinatal mortality and traffic-related air pollution].

A saúde infantil, que tem como principal indicador o coeficiente de mortalidade infantil, constitui-se ainda em um importante problema de saúde pública em escala mundial. Uma das Metas de Desenvolvimento do Milênio (Millenium Development Goals – MDG), estabelecidas pelos países e organizações internacionais, é a redução da mortalidade em menores de cinco anos em dois terços no período de 1990 a...
