Abstract

Изобретение относится к оборудованию, применяемому, например, в системах вентиляции и кондиционирования.Установка содержат теплообменник с каналами первичного и вторичного носителей и, по меньшей мере, один побудитель циркуляции для носителя. Теплооюменник выполнен в виде ящика параллелепипедной формы, содержащего параллельные стенки, ограничивающие два одинаковых канала с возможностью циркуляции в них противотоком первичного и вторичного носителей.Каналы в сечении выполнены волнистыми, что позволяет значительно обеспылить поступающий к комнату воздух.Стенки каналов выполнены легкосъемочными или установлены с возможностью поворота вокруг одной из своих сторон, что обеспечивает свободный доступ к каждой из них на всей их поверхности для очистки каналов от пыли, грязи и т.п., которые там накапливаются.Конструкция установки предусматривает возможноть установки средств подогрева и увлажнения.Фиг.: 11The invention relates to equipment used, for example, in ventilation and air conditioning systems. The installation includes a heat exchanger with channels of primary and secondary carriers and at least one inducer of circulation for the carrier. The heat exchanger is made in the form of a box of a parallelepiped shape containing parallel walls restricting two identical channels with the possibility of circulation in them by countercurrent primary and secondary carriers. turning around one of its sides, which provides free access to each of them on their entire surface to clean the channels of dust, dirt, etc. n., which accumulate there. The design of the installation provides for the possibility of installing heating and humidification means. Fig .: 11
