Compared with the traditional air conditioning terminal, the cold beam system is a more economical and environmentally friendly choice. Air type cooling beam is suitable for large cooling load room, built-in high performance induced fan, combined with the advantages of water medium cooling and heating, has the advantages of large heat exchange, good energy saving effect, low noise, uniform air, high comfort. CDKU air model cold beam can operate under dry and wet conditions, internal condensate water tray, optional condensate water lifting pump, effectively solve the problem of condensate water generation and discharge during refrigeration.
