In new energy efficient houses, greater levels of air tightness lead to poor indoor air quality and other, more visible impacts such as condensation damage and mould growth.

Aeolus4 is the 3rd generation of Comefri fan selection software (1st release of Aeolus was in late 2014). The software allows the customer to obtain a large quantity of catalogue information, including fan curves, quotes, function fan ranges and application conditions. Centrifugal Fan Design software, free download It is important to ensure sufficient clearance on both the suction and exhaust sides of the fan. Insufficient clearance on the suction side of the fan will increase the inlet velocity which will lead to turbulence. Industrial Fan Software. Designed to meet the needs of the air moving industry, including HVAC, our industrial fan software is a dynamic tool that accurately performs sizing of centrifugal fans and blowers, and axial fans. For the sizing of fans, the programming logic is developed according to engineering concepts homologated by international standards and institutions.

MAJOR CENTRIFUGAL FAN PARTS
Centrifugal fan design is usually given when the conditions are: the volume flow rate, total pressure, the working medium and its density (or the working medium temperature), and sometimes there are structural requirements and special requirements.
Design requirements of a large centrifugal fan are: to meet the required flow and pressure conditions at the highest point of efficiency should be near; maximum efficiency value to be as large as some of the efficiency curve flat; pressure curve to a wide range of stability; fan of simple structure , technology is good; convenient choice of materials and accessories; have sufficient strength, stiffness, safe and reliable; running stable, low noise; adjusted performance, work adaptability; fan size as small as possible, light weight; operation and maintenance , disassemble easy transport.
However, while meeting all the requirements above, is generally not possible. In the aerodynamic performance and structural (strength, process) there are contradictions between the often, usually to seize the main contradiction solve the problem. This requires designers to choose the right design to address the principal contradiction. For example:
With the use of different fans, not the same requirement, such as public buildings used as a ventilation fan is generally used with, the most important requirement is that the general low-noise, multi-blade centrifugal fan with this feature; and require large flow The centrifugal fan is usually double-suction type; for some of the high-pressure centrifugal fan, low specific speed, the relative proportion of the leakage loss is generally larger
Fan Parts-Impeller Design
The centrifugal fans impeller have five basic blade shapes, and a number of impeller configurations (i.e) DWDI (Double width double inlet) or SWSI (Single width single inlet). The impeller design will depend on the aerodynamic duty and the operating conditions.
Blade Design
TYPES OF BLADE DESIGN

Backward inclined, backward curved blades

A highly efficient design of impeller. Its inherent strength means that in addition to handling air, it can be used with gases containing moderate amounts of erosive particles and at high temperatures. It can carry liners and hard surfacing, if required.
Backward inclined, flat plate blades
An efficient and strong shape, this design is a cost-effective alternative to the backward curved design but with flat plate blades instead of curved. This results in a slightly lower efficiency, compensated by the easier fitting of liners.

Backward inclined, forward curved blades
Also termed radial tipped blades, this design reduces the potential for dust build-up on the underside of the blades in applications with moderate amounts of gas-borne dust.
Aerofoil blades
3D MODEL OF AEROFOIL IMPELLER
Aerofoil bladed impellers are most commonly used in applications handling large volumes at low pressures. This highly efficient design of fan is used in clean air or with gases containing small amounts of erosive particles.
Radial blades

Centrifugal Fan Design Pdf

Forming a rotor which is essentially a large paddle wheel, this design results in a relatively inefficient fan with a power consumption higher than that using the much more common backward inclined blade. Its inherent mechanical strength and resistance to wear mean it is generally used when high quantities of abrasive dust are present in the gas stream, or when very high gas temperatures are expected.

Impeller configurations

Single or double inlet
A double inlet impeller consists of two single inlet impellers back to back on the shaft sharing a common backplate, providing almost double the flow of a single inlet fan. The selection of a double inlet fan results in a smaller diameter, faster (and perhaps cheaper) machine compared to the single inlet alternative. Single or multiple stage
A multi-stage fan consists of two or more impellers mounted on the same shaft. The air or gas flow passes through each one in turn, with a consequent increase in pressure
