Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. "Roof natural ventilation selection and installation of the" national standard atlas 1. Scope: This portfolio is suitable for large-scale industrial plants and civil tall space economically rational use of natural ventilation in place, and should take full account of local outdoor weather conditions. 2, natural ventilation type: includes streamlined roof natural ventilation and natural ventilation roof cyclone type two kinds. Does not include all types of roof exhaust hood. Streamlined roof natural ventilation is installed on the roof rtc roof fan price, use hot action indoor and outdoor temperature reaches the formation of indoor air replacement device. In between the boiler, turbine and so have a lot of heat between the workshop used this device. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. The primary principle of natural ventilation windows ventilators choice is the choice of the selected model and the number of installed capacity to meet the requirements needed to ventilate the room rtc roof fan parameters that meet the needs of the people in the room for the amount of fresh air . Windows and doors, curtain walls as natural ventilation windows and doors, curtain wall of a companion product, its structure and material terms of demanding, its wind pressure, anti-rain and noise insulation, air tightness and thermal performance requirements for roof and doors match rtc fan, and you want to achieve with the doors and windows with life, choose the type of ventilation and the number of installations, to consider building their own combination of factors. First, we must consider the location of the climatic conditions of the building, such as the basic wind pressure and temperature conditions. Ventilation different pressure values ??on the same type and length of the obtained number of ventilators are different, to choose the type ventilators weatherproof performance indicators inform itself to meet the requirements. Temperature aspect to consider whether the cold regions, namely the type of ventilation through the K value and the possibility for the use of the U-value, in the cold season is not condensation. rtc roof fan specifications | Beijing rtc roof fan | Flextronics ventilation provided by Liaocheng Wei Chong ventilation equipment.
