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 ...
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) ...
Transit-oriented Development from the View of Traditional City Model
(
Qatar University Press
, 2023 , Conference Paper)
Several communities have adopted the transit-oriented development (TOD) model to improve the urban form of the city. Through the TOD model, citizens are enabled and encouraged to travel by public transit and live near it, ...
Modeling and optimization of poultry house passive cooling strategies in semiarid climates
(
Elsevier Ltd
, 2021 , Article)
Meeting hygrothermal and air quality requirements in livestock dwellings is crucial for upholding production quality standards. However, ventilation and air-conditioning in such enclosures is very energy-intensive, especially ...
A comprehensive optimization study of personal cooling radiant desks integrated to HVAC system for energy efficiency and thermal comfort in office buildings
(
Elsevier
, 2023 , Article)
Personal comfort systems (PCS) maintain the occupant's preferred thermal environment and expand his thermal comfort experience under varying environmental conditions. Among PCSs, radiant-based systems are popular due to ...
Life cycle assessment of desiccant – Dew point evaporative cooling systems with water reclamation for poultry houses in hot and humid climate
(
Elsevier
, 2022 , Article)
Desiccant – dew point evaporative based cooling systems is known to be an effective system for the ventilation and cooling of poultry houses in hot and humid climates. However, they suffer from high water consumption that ...
A sustainable localised air distribution system for enhancing thermal environment and indoor air quality of poultry house for semiarid region
(
Academic Press
, 2021 , Article)
This work compares the performance of three passive cooling systems in meeting thermal and indoor air quality requirements in a poultry house located in semi-arid climate. The first two systems are a direct evaporative ...
Performance assessment of evaporatively-cooled window driven by solar chimney in hot and humid climates
(
Elsevier Ltd
, 2018 , Article)
This study investigates the application of the evaporatively-cooled window system in hot and humid climates and assesses its seasonal performance and benefits in terms of energy savings. The validated system is a hybrid ...
Quantifying savings in spaces energy demands and CO2 emissions by shading and lighting controls in the Arabian Gulf
(
Elsevier
, 2018 , Article)
Despite the deceleration in worldwide annual energy consumption and CO2 emissions, many countries, such as in the Arabian Gulf, are still unarguably far from following this international trend. This study investigates the ...
Comparative analysis of sustainable desiccant – Evaporative based ventilation systems for a typical Qatari poultry house
(
Elsevier Ltd
, 2021 , Article)
Direct evaporative cooling is the typically adopted ventilation system in poultry houses in hot climates. This type of cooling is inefficient during period of relatively high humidity resulting in degraded thermal comfort ...
