Development of Air Ventilation Garments with Small Fan Panels to Improve Thermal Comfort

Thermal Comfort in Offices – Natural Ventilation vs. Air Conditioning

Based on both subjective and objective data, a study was carried out in order to identify differences in the perception of thermal comfort of office workers in naturally ventilated and air-conditioned buildings. The analysis of the interviews shows that occupants of naturally ventilated office buildings are significantly more satisfied with their thermal environment than occupants in air-condit...

Energy Efficient Laboratory Design: A Novel Approach to Improve Indoor Air Quality and Thermal Comfort

Nanotechnology promises to improve the quality of human life, but it has also provoked concerns about potential adverse health effects on workers, the environment and consumers. Effective risk assessment and risk management of nanotechnology requires: 1) knowing how engineered nanoscale particles (NPs) can gain entry into the human body (routes of exposure); 2) knowing whether engineered NPs ca...

Thermal comfort enhancement by using a ceiling fan

A parametric analysis on the effect of using a ceiling fan in an air-conditioned room is performed by twodimensional (2D) numerical simulation of steady state airflow and heat transfer. Thermal comfort analysis is done for a person standing in a room with an inlet and an outlet for air conditioning and a ceiling fan. Representative three-dimensional (3D) simulation is also performed for the com...

Thermal comfort performance of sports garments with objective and subjective measurements

Subjective wear trials have been carried out to determine thermal comfort performance of knitted sports garments whose objective thermal comfort parameters are determined in a preceding study in fabric form. Physiological measurements (skin and microclimate temperature, microclimate relative humidity, heart rate and sweat amount) and psychological rating results (coolness, dampness and comfort)...
