BACKGROUND Fanger's PMV equation is the result of the combined quantitative effects of the air temperature, mean radiant temperature, relative air velocity, humidity, activity level and clothing insulation. METHODS This paper contains a comparison of suit dresses and summer clothes in terms of thermal comfort, Fanger's PMV equation. Studies were processed in the winter for an office, which lo...

Subjects exposed to uniform environments were polled for their local and overall (whole-body) thermal sensation and comfort. Sensation and comfort for local body parts vary greatly. In cool environments, hands and feet feel colder than other body parts. The head, insensitive to cold but sensitive to warm, feels warmer than the rest of the body in warm environments. Overall sensation and comfort...

The present work is focused on the control of indoor thermal comfort in buildings equipped with HVAC (Heating, Ventilation and Air Conditioning) systems. The occupants’ thermal comfort sensation is addressed here by the well-known comfort index (PMV Predicted Mean Vote). In this context, different strategies for the control algorithms are proposed by using only-one-actuator system that can be a...

Ensuring thermal comfort is an important goal in the operation of any office building. Often these buildings are therefore controlled according to the predicted mean vote (PMV) model which is also adopted as the ISO 7730 norm. This model predicts the mean thermal preferences of an average group of people that would satisfy the thermal comfort needs of about 80% of the occupants. It is derived f...

despite the similar performance of bazaar1 in different cities of iran, there are some the skeletal differences between markets in different climates. the bazaar roof protects customers against natural events in any climate. the ceiling height and the sitting down of the bazaar`s floor are determined based on the need for air circulation and movement in various climates. hence, combination of a...

accumulation of unmanaged industrial solid waste, especially in developing countries has resulted in an increased environmental concern. in view of utilization of industrial solid waste the recycled paper mill waste (rpmw) – cement composite bricks were designed and developed. in order to investigate the environmental performance of sustainable construction materials two small scale model house...

The thermal environment outdoors affects human comfort and health. Mental and physical performance is reduced at high levels of air temperature being a problem especially in tropical climates. This paper deals with human comfort in the warm-humid city of Guayaquil, Ecuador. The main aim was to examine the influence of urban micrometeorological conditions on people's subjective thermal perceptio...

The purpose of this study was to investigate the effects of a floor heating and air conditioning system on thermal responses of the elderly. Eight elderly men and eight university students sat for 90 minutes in a chair under the following 3 conditions: air conditioning system (A), floor heating system (F) and no heating system (C). The air temperature of sitting head height for condition A was ...
