Installing ceiling fans

How do I connect with the duct fan ventilation installation – a few interesting
observations. Ceiling fans are a major element of supply and ventilation
exhaust air flow capacity of approximately 10 000 m³ / h. Of course, there
are ceiling fans with high airflow, but mostly great performance are achieved by air ventilation units.
Ventilation systems in residential, office, etc., with flow rate
air to about 5000 m³ / h are usually performed using the channel cross-section
circular with a maximum diameter of 500 mm on the main bus. Increased air capacity
require ventilation ducts with rectangular cross section, much less – a square.

Figure 1 (according to the book “Guide, Ventilation usable”, 1999) shows the dependence of the circuit and losses pressure on the shape of the channel for the air speed of 6 m / s. The diagram clearly shows that the lowest resistance movement and the smallest surface of the material used (usually steel) for
get a cross section through the use of channels of circular cross section -
most pipes Spiro ®. During the design and assembly of each fan
channel (no matter what is its cross-section: circular, rectangular or square)
should keep a few principles:
• it should be installed subject to the straight sections of the channel at the inlet and outlet
fan. This avoids the pressure loss and a decline in system efficiency,
turbulence caused by air flow. The length of these segments is shown in Figure 2;
• straight sections of channels can not contain filters, butterfly valves, etc. components;
• For rectangular or square channel hydraulic diameter is determined from the relationship:

Installing ceiling fans. When designing the ventilation systems, be sure to meet required
parameters of ventilation air. This is especially important in air intake systems.
In addition to the proper performance of the flow, the air should be heated (or
cooled) to the proper temperature and be of suitable purity required for
data space. With the above assumptions result in the use of appropriate equipment
ventilation systems. These include air filters, duct heaters (water or
Electric), silencers, dampers, and air diffusers and uptake ventilators.

In order to avoid transmission of vibrations from the fan in a ventilation duct system it is
recommended to use mounting brackets or flexible connections (Installing ceiling fans)
Ventilation systems should not carry any vibrations on the building structure or
facility where they are installed. For this purpose, the suspension systems and components
insulating (washers, spring). Please also note whether the site (exchange
filters) and cleaning of the ventilation system. It should allow access to filters and
through channels such as flap revision after installing ceiling fans.
