Experimental study on effective placement of PCM packets in cooling vest to improve performance in warm environment
(
American Society of Mechanical Engineers
, 2017 , Conference Paper)
Global warming has increased the risk of heat stress of outdoor workers and one measure against heat stress is wearing passive personal cooling clothing. Passive body cooling systems, including phase change material (PCM) ...
Experimental analysis of double and triple glazed facades with different shading devices in Qatar
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
The design of fully-glazed facades on buildings has become very popular, especially in hot regions where the use of natural ventilation is not recommended. The integration of shading devices to facade surfaces has been ...
Effect of PCM packet mass and melting temperature on cooling vest performance
(
ASHRAE
, 2016 , Conference Paper)
Workers in hot environment experience high heat stresses that affect their productivity and working intervals. A cooling vest containing phase change material packets (PCMs) is used as a passive body cooling method to ...
Mathematical modeling of PCM cooling vest for workers in hot climates
(
American Society of Heating, Refrigerating and Air-Conditioning Engineers, ASHRAE
, 2016 , Conference Paper)
A cooling vest containing phase change materials (PCM) made of salt mixtures that melts at a specific temperature helps in maintaining the skin temperature of the covered parts at a comfortable level. A dynamic thermal ...
The effect of PCM placement on torso cooling vest for an active human in hot environment
(
Elsevier Ltd
, 2016 , Article)
The distribution of phase change material (PCM) packets on a cooling vest worn by active human in hot environments is investigated using an integrated fabric-PCM and bio-heat model. The model considered the effect of added ...
Experimental study on using PCMs of different melting temperatures in one cooling vest to reduce its weight and improve comfort
(
Elsevier Ltd
, 2017 , Article)
This study aims at evaluating experimentally phase change material (PCM) cooling vest performance when incorporating two types of PCM with different melting temperatures with varied PCM placement on the lower, upper, front ...
Shading and day-lighting controls energy savings in offices with fully-Glazed façades in hot climates
(
Elsevier Ltd
, 2017 , Article)
Shading devices installed on windows are designed to reduce solar radiation transmission into the space by absorbing and reflecting radiation rays. This study investigates the effect of shading and day-lighting controls ...
Cooling vest with optimized PCM arrangement targeting torso sensitive areas that trigger comfort when cooled for improving human comfort in hot conditions
(
Elsevier Ltd
, 2017 , Article)
The objective of this work is to optimize the arrangement of Phase Change Material (PCM) packets in a cooling vest by targeting torso segments that can trigger comfort when cooled. An integrated fabric-PCM and bio-heat ...
PCM cooling vest for improving thermal comfort in hot environment
(
Elsevier Masson s.r.l.
, 2016 , Article)
A cooling vest containing phase change materials (PCM) can help in maintaining the skin temperature of the covered parts at a comfortable level. A transient mathematical model of heat and mass transfer through clothing ...
