ReSpire WP1200: Ontwerp Ventilatiesysteem

The objective of the National Technology project ReSpire is to develop a personal cooling system for soldiers. The aim is to enhance the soldiers sweat efficiency using a stream of air ventilating around the soldier’s torso. This document describes the design of the cooling system. Several attempts to develop cooling systems are discussed first....

How to measure thermal effects of personal cooling systems: Human, thermal manikin and human simulator study

Thermal effects, such as cooling power and thermophysiological responses initiated upon application of a personal cooling system, can be assessed with (i) humans, (ii) a thermal manikin and (iii) a thermophysiological human simulator. In order to compare these methods, a cooling shirt (mild cooling) and an ice vest (strong cooling) were measured...

Heat stress reduction of helicopter crew wearing a ventilated vest

Background: Helicopter pilots are often exposed to periods of high heat strain, especially when wearing survival suits. Therefore, a prototype of a ventilated vest was evaluated on its capability to reduce the heat strain of helicopter pilots during a 2-h simulated flight. Hypothesis: It was hypothesized that the ventilated vest would reduce...
