deliverable 1.1. : Advanced cooling concepts

Authors: Manuel Bühler, Hein Daanen, Nicole Papen-Botterhuis, Ana-Maria Popa, Herman Reezigt

Rationale

In the Prospie project we aim to make a working prototype of a mobile, comfortable PPE which is effective in hot situations.  

Methods

We investigated and summarized the literature regarding cooling systems in and under garments. An example of environmental conditions for the ceramic and glass industry was defined that may be of use for the Prospie-project.

Results

Four existing cooling techniques are described in detail. PCMs will be integrated to absorb energy during the temperature peaks. Evaporative water cooling will be combined with ventilation to cool in a continuous manner in the periods between the peaks of high temperature. Hygroscopic salts will be integrated to avoid an excess of humidity on the user’s skin. Two designs for PPE are suggested. One is an overall with homogeneous structure, the other uses different designs depending on the body part. In both designs, evaporative cooling will be used to act against the steady high temperature between 40 and 60 °C and cooling with PCM is used to neutralize the short high temperature peaks of up to 150 °C.

Applicability

The literature review and proposed systems form a guideline for other deliverables in the Prospie project.
