Air conditioning and temperature control
systems are developed to generate the condition of comfort within the work and
home premises. They control humidity, temperature and flow of air within Air conditioning systems are integrated with three various controls-humidistats,
temperature control, and air stats. In this blog, we are discussing the
importance of Centrifugal and Axial fans.
What Are Axial
Flow Fans?
The name axial is given to these category
fans owing to the air direction generated by creating them. The first
electronically driven powered fans came in the market in the year 1880. Blades
moving around axis flow air parallel to the axis and move air with force in a
similar direction. The typical mode of axial fans is utilized to exhaust air from
the process used for supplying fresh air and major spot cooling of the room,
people and machinery.
Axial flow fans having four or six blades and diameters of 6-18 feet are commonly
employed in air-cooled heat exchangers, however larger and smaller fans are
used occasionally. The plastic fan blades are helpful for air temperatures upto
175-degree Fahrenheit, and metal blades are used for higher air temperatures.
Most frequently electric motors are used
as fan drivers, however, at some frequencies turbines are also used. Speed
reduction is usually accomplished with the use of V belts, high torque drive
belts, reduction gearboxes.
Variable pitch fans are specially used
for facilitating process side temperature control in air-cooked exchangers. The
pitch of the blade is automatically adjusted for providing the required airflow
for maintaining the desired outlet temperature of the process fluid.
Industrial
Extractor Fans
The heavy-duty design and performance of
Axial Flow fans make it suitable for every environment. They are perfectly
suited as an effective means for circulating huge amount of air across the
premises.
Air
Flow Direction-Air that moves from motor to impeller is said as
standard. And the air moving from impeller to motor is moved on request.
Static
Pressure- up to 100 mm weight
Comprehensive
choice of diameters- Range from 250 mm to 1600 mm
Introduction
To Centrifugal Fans
Typically centrifugal fans have eight
types that draw air into the inlet of housing blower via the wheel and
discharges it at 90 degrees. There are two major types of blowers-Pressure
blowers and volume blowers. Pressure blowers are specially designed to drive or
push air at high pressures. Fans are made of SS, fabricated steel or cast
aluminum.
