The human body will release excess heat into the environment, so the body can continue to operate. The heat transfer is proportional to temperature difference. In cold environments, the body loses more heat to the environment and in hot environments the body does not release enough heat.

Analysis of Indoor Thermal Comfort of Room Space in the International Standard Hotel Building

This study quantifies the influence of green spaces on microclimate and PM10 concentration in a typical residential district of Nanjing China by employing the CFD-based and microclimate model ENVI-met 4. Five green indices, related to quantity and structure of vegetation, are employed to investigate the impact of different types grass, shrub and tree and layouts of a green space located in the center of the residential district under an average Nanjing summer day.

Results show that the thermal comfort expressed by the mean radiant temperature MRT and the predicted mean vote PMV is slightly enhanced with increasing green quantity, especially trees, even though more trees may increase the wind blocking effect with a consequent slight increase of pollutant concentration.

In this regard, a single patch of trees located in the central part of the green space is preferable. The green indices are shown to be useful for studying the relationship between green space morphology, microclimate and air quality in cities. Download to read the full article text.

For this purpose, air temperature, air relative humidity, air flow rate and carbon dioxide concentration were measured and the mean radiant temperature was determined. Thermal sensations of the students occupying the rooms of the building were evaluated with the use of a questionnaire. The students used a seven-point scale of thermal comfort. The microclimate measurement results were used to determine the Predicted Mean Vote and the Predicted Percentage Dissatisfied indices.

Thermal comfort: analysis and applications in environmental engineering,

The objective of this study was to analyze the indoor thermal comfort of room space international standard hotel buildings. The sample of the study was guests staying at five international standard hotels. Primary data was collected through survey and questionnaires.

DOI : Objective: The main focus in the current work is to investigate how diverse heating systems and their locations influence the indoor thermal environment in an exhaust- ventilated room. Methods: Four systems for heating the room were used in the current study, in which, heat was transferred by convection and radiation. The four systems were: wall and floor heating at low temperatures, Medium Temperature Radiator M. Computational Fluid Dynamics CFD simulation was used to investigate indoor temperature, vertical air temperature gradient and thermal comfort for each case.

This study quantifies the influence of green spaces on microclimate and PM10 concentration in a typical residential district of Nanjing China by employing the CFD-based and microclimate model ENVI-met 4. Five green indices, related to quantity and structure of vegetation, are employed to investigate the impact of different types grass, shrub and tree and layouts of a green space located in the center of the residential district under an average Nanjing summer day. Results show that the thermal comfort expressed by the mean radiant temperature MRT and the predicted mean vote PMV is slightly enhanced with increasing green quantity, especially trees, even though more trees may increase the wind blocking effect with a consequent slight increase of pollutant concentration.

Два часа спустя был издан ставший знаковым приказ: СОТРУДНИК КАРЛ ОСТИН УВОЛЕН ЗА НЕДОСТОЙНЫЙ ПОСТУПОК С этого дня никто больше не доставлял ей неприятностей; всем стало ясно, что Сьюзан Флетчер - любимица коммандера Стратмора. Но не только молодые криптографы научились уважать Стратмора; еще в начале своей карьеры он был замечен начальством как человек, разработавший целый ряд неортодоксальных и в высшей степени успешных разведывательных операций. Продвигаясь по служебной лестнице, Тревор Стратмор прославился умением сжато и одновременно глубоко анализировать сложнейшие ситуации. Он обладал почти сверхъестественной способностью преодолевать моральные затруднения, с которыми нередко бывают связаны сложные решения агентства, и действовать без угрызений совести в интересах всеобщего блага. Ни у кого не вызывало сомнений, что Стратмор любит свою страну. Он был известен среди сотрудников, он пользовался репутацией патриота и идеалиста… честного человека в мире, сотканном из лжи. За годы, прошедшие после появления в АНБ Сьюзан, Стратмор поднялся с поста начальника Отдела развития криптографии до второй по важности позиции во всем агентстве.

Все, кто имел отношение к криптографии, знали, что о АНБ собраны лучшие криптографические умы нашей планеты. Каждую весну, когда частные фирмы начинают охоту за талантливой молодежью, соблазняя ее неприлично высокими окладами и фондовыми опционами в придачу, АНБ внимательно наблюдает за этим, выделяет наиболее подходящих и удваивает предлагаемую сумму. АНБ покупает все, что ему требуется. Дрожа от нетерпения, Сьюзан вылетела в Вашингтон. В международном аэропорту Далласа девушку встретил шофер АНБ, доставивший ее в Форт-Мид. В тот год аналогичное приглашение получили еще сорок кандидатов. Двадцативосьмилетняя Сьюзан оказалась среди них младшей и к тому же единственной женщиной.

Темнота коридора перетекла в просторное цементное помещение, пропитанное запахом пота и алкоголя, и Беккеру открылась абсолютно сюрреалистическая картина: в глубокой пещере двигались, слившись в сплошную массу, сотни человеческих тел. Они наклонялись и распрямлялись, прижав руки к бокам, а их головы при этом раскачивались, как безжизненные шары, едва прикрепленные к негнущимся спинам. Какие-то безумцы ныряли со сцены в это людское море, и его волны швыряли их вперед и назад, как волейбольные мячи на пляже. Откуда-то сверху падали пульсирующие стробоскопические вспышки света, придававшие всему этому сходство со старым немым кино. У дальней стены дрожали включенные на полную мощность динамики, и даже самые неистовые танцоры не могли подойти к ним ближе чем на десять метров. Беккер заткнул уши и оглядел толпу. Куда бы ни падал его взгляд, всюду мелькали красно-бело-синие прически.

Although thermal sensitivity varies from one person to another, according to age the very young and very old being particularly sensitive , gender, dress, activity, cultural habits, etc.

Human thermal comfort is the state of mind that expresses satisfaction with the surrounding environment, according to ASHRAE Standard
