3. Translate the following text into English in written form.
Для отопления зданий и сооружений в настоящее время преимущественно используют воду или атмосферный воздух, гораздо реже водяной пар или нагретые газы. В зависимости от вида используемого в системе отопления теплоносителя, их принято называть «системами водяного, парового, воздушного или газового отопления».
Variant 1. Сопоставим характерные свойства указанных видов теплоносителя при использовании их в системах отопления.
Газы, образующиеся при сжигании твёрдого, жидкого или газообразного органического топлива, имеют сравнительно высокую температуру и применимы в тех случаях, когда в соответствии с санитарно-гигиеническими требованиями удаётся ограничить температуру теплоотдающей поверхности отопительных приборов. Высокотемпературные продукты сгорания топлива могут выпускаться непосредственно в помещения или сооружения, но при этом ухудшается состояние их воздушной среды, что в большинстве случаев недопустимо. Удаление же продуктов сгорания наружу по каналам усложняет конструкцию и понижает КПД отопительной установки. При этом возникает необходимость решения экологических проблем, связанных с возможным загрязнением атмосферного воздуха продуктами сгорания вблизи отапливаемых объектов.
В отличие от горячих газов вода, воздух и пар используются многократно в режиме циркуляции и без загрязнения окружающей здание среды.
Вода представляет собой жидкую, практически несжимаемую среду со значительной плотностью и теплоёмкостью. Вода изменяет плотность, объём и вязкость в зависимости от температуры, а температуру кипения - в зависимости от давления, способна поглощать (абсорбировать) или выделять растворимые в ней газы при изменении температуры и давления.
Пар является легкоподвижной средой со сравнительно малой плотностью. Температура и плотность пара зависят от давления. Пар значительно изменяет объём и теплосодержание (энтальпию) при фазовом превращении.
Воздух также является легкоподвижной средой со сравнительно малыми вязкостью, плотностью и теплоёмкостью, изменяющей плотность и объём в зависимости от температуры.
Variant 2. Перечислим преимущества и недостатки основных теплоносителей для отопления.
При использовании воды обеспечивается достаточно равномерная температура помещений, можно ограничить температуру поверхности отопительных приборов, достигается бесшумность движения в теплопроводах. Недостатком является большое гидростатическое давление в системах. Тепловая инерция воды замедляет регулирование теплопередачи отопительных приборов.
При использовании пара достигается быстрое прогревание приборов и отапливаемых помещений. Гидростатическое давление пара в вертикальных трубах по сравнению с водой минимально. Однако пар как теплоноситель не отвечает санитарно-гигиеническим требованиям, движение его в трубах сопровождается шумом.
При использовании воздуха можно обеспечить быстрое изменение или равномерность температуры помещений, избежать установки отопительных приборов, совмещать отопление с вентиляцией помещений, достигать бесшумности его движения в воздуховодах и каналах. Недостатками являются его малая теплоаккумулирующая способность, значительные площадь поперечного сечения и расход металла на воздуховоды, относительно большое понижение температуры по их длине.
В настоящее время в Беларуси применяют центральные системы в основном водяного и, значительно реже, парового отопления, местные и центральные системы воздушного отопления, а также печное отопление в сельской местности.
