HVAC system corner duct design requirements to meet the functional needs of construction and control of investment costs, air conditioning pipe design and selection HVAC Engineering is an important part.
With the constant development of social science and technology, the height of building design, the environment comfort and the degree of intelligence will be higher and higher. Central air-conditioning system is one of the indispensable equipment and facilities in the building. Whether it is a star hotel, a shopping mall, Office buildings, hospital operating room, high-precision processing equipment, HVAC system corner duct design and selection, is directly related to the HVAC late operating results.
The function of the HVAC system is to deliver cold and hot water to a variety of air handling and air conditioning terminals. Therefore, HVAC system to have sufficient transport capacity to meet the air conditioning system on the cold and heat load requirements. The refrigerated circulating water is distributed according to the required flow rate, and the assumed flow velocity method is used to determine the pipe diameter and the resistance. First of all, to determine the way for water supply and return pipelines, in the building plan according to the technical parameters of the end air-conditioning equipment, reasonable layout of the pipe and pipe diameter, and draw the pipeline hydraulic plan. In the pipeline hydraulic plane marked the length of the pipeline at each stage and end of the air-conditioning equipment flow. Using the assumed velocity method and the pipe flow in each stage, the pipe diameter is accurately calculated and a reasonable hydraulic flow rate is selected.
Through the HVAC system corner duct design, hydraulic calculation and combined with investment costs, building types, a reasonable choice of matching HVAC pipe, HVAC operation stability to make an important step in ensuring the applicability of HVAC system design And economic, reliability, advanced and energy-saving.
