Passive Cooling Technologies

Active versus passive cooling during neonatal transport.

BACKGROUND AND OBJECTIVE Therapeutic hypothermia is now the standard of care for hypoxic-ischemic encephalopathy. Treatment should be started early, and it is often necessary to transfer the infant to a regional NICU for ongoing care. There are no large studies reporting outcomes from infants cooled passively compared with active (servo-controlled) cooling during transfer. Our goal was to revie...

Induction of Cooling With a Passive Head and Neck Cooling Device

Therapeutic hypothermia improves clinical outcome in patients with global cerebral ischemia after cardiac arrest and in newborns with hypoxic ischemic encephalopathy. Hypothermia also seems promising in other cerebrovascular diseases, for example, ischemic and hemorrhagic stroke. In experimental models, the sooner hypothermia was initiated, the more distinctive neuroprotection was. Although cli...

Modelling Buoyancy Induced Flows of Passive Cooling Systems

The main objective of this study is to develop and validate a systematic methodology to model a system of buried pipes, assisted by a solar chimney to promote the natural ventilation, in the whole building simulation software ESP-r (Clarke 2001), from a software user perspective. This development was supported by monitored data collected at an experimental site in Évora, Portugal. A multi-zone ...

Green Material Prospects for Passive Evaporative Cooling Systems: Geopolymers

Passive cooling techniques have been used mostly in countries with hot and arid climates such as Iran, Egypt, and India. However, the use of this important technology has not been seriously considered until a time of energy crisis, and consequently, environmental crisis scenarios, emerge. Scholars have renewed their interest in investigating passive cooling technology, particularly the aspects ...
