First, the use and characteristics of the jet induced fan (YDF)
The induced fan is a part of the ducted jet induced ventilation system. It is composed of an air supply fan and an exhaust fan. The use of a pipe free jet to induce ventilation system can save the cost of designing, manufacturing, installing the wind pipes and other supporting projects. This part is much more expensive than the inducible fan set used, and the wind pressure required for the ventilation duct, air blower and exhaust fan at the whole level is much smaller than that of the pipe. The wind turbines with high wind volume and lower wind pressure can be used to reduce the required power and greatly reduce operation costs and investment costs. When the exhaust fan stops running, the induced fan can still work and play the role of partial ventilation and ventilation.
The induction fan has a built-in high efficiency centrifugal fan with low noise, small size, light weight and convenient hoisting (vertical and horizontal installation). It is easy to maintain and is widely used in underground parking, gymnasium, workshop, warehouse, supermarket, supermarket, recreation ground and other large areas of ventilation.
Two, the performance parameter table of the jet induced fan (YDF) Three, the calculation of the number of jet induced fan (YDF)
The number of inducible fans, in consideration of the ventilation mode (mechanical ventilation, natural discharge, natural air ventilation), with no partition wall, space shape, according to the area required for each induction fan, can refer to the following table:
Four, installation layout of jet induced fan (YDF)
The inducement fan unit is an important intermediate ventilation link in the whole air supply and exhaust system. The position of inlet and exhaust air outlet is very important to induce the installation position of the fan, which is directly related to the formation of reasonable air flow. The ideal layout is to let the exhaust fan form the main air flow in the space, and to induce the fan's induced air supply to complete the whole space's sending and exhausting wind.
