In the coming decades, global warming and increase in temperature, in different regions of the world, may change indoor and outdoor thermal comfort conditions and human health. The aim of this research was to study the effects of global warming on thermal comfort conditions in indoor ambiences in Iran. To study the increase in temperature, model for assessment of greenhouse-gas induced climate ...

The study identifies the gap between actual thermal sensation and theoretical comfort calculated through simulated microclimate data in different urban configurations in a tropical, high-density, megacity: Dhaka. The methodology stated here could be applied for evaluating outdoor comfort conditions for future urban areas at an early design stage. To apply the concept of theoretical comfort it i...

this paper discusses the results of the full-scale field measurement study to investigate the most efficient application strategy of the hybrid turbine ventilator (htv) in improving the indoor thermal comfort in hot-humid tropics. the effects of three different htv application strategies performance on improving the levels of indoor air temperature, relative humidity (rh) and air velocity were ...

Thermal comfort of building occupants is a major criterion in evaluating the performance of building systems. It is also a dominant factor in designing and optimizing building’s operation. However, existing thermal comfort models, such as Finger’s model currently adopted by ASHRAE Standard 55, rely on factors that require bulky and expensive equipment to measure. This paper attempts to take a r...

Model Predictive control is an advanced control technique that has been used to optimize thermal comfort in buildings. Nowadays, the new buildings are characterized by an important inertia as well as low power heating systems. Since the thermal losses are very low, taking into account the intermittent occupancies in the control strategy is questionable. More precisely, in this paper, two model ...

The effect of vertical air temperature gradient on overall and local thermal comfort at different overall thermal sensations and room air temperatures (at 0.6m height) was investigated in a room served by displacement ventilation system. Sixty tropically acclimatized subjects performed sedentary office work for a period of 3 h during each session of the experiment. Nominal vertical air temperat...

Due to the current environmental situation, energy saving has become the leading drive in modern research. Although the residential houses in tropical climate do not use air conditioning to maintain thermal comfort in order to avoid use of electricity. As the thermal comfort is maintained by adequate envelope composition and natural ventilation, this paper shows that it is possible to determine...

The properties of gas mixture exert a large effect on thermal exchange from the human body and finally on the comfort temperature in the hyperbaric environment. Equations describing density, viscosity, specific heat capacity, thermal conductivity of real gas mixture as the function of helium contents, temperature and the total gas pressure were derived. It makes possible to improve the comfort ...
