Effect of
fan selection on capacity and Noise level & Control Options
Since cooling groups are used in
super markets, cold storage facilities,
air conditioner, process cooling
systems etc. in residential centers, low noise level during the operation of
the groups is an important criterion.
Condenser fans and compressors are the
two components that are sources of noise in cooling groups. The noise level
which results primarily from the
fan motor and the design of the fan blades is
determined by evaluating manufacturer’s data and checked in terms of
conformance to the prescribed specifications. The sound level may be reduced by
decreasing motor rotation, if need be; in this case the heat transfer area of
the heat exchanger should be increased in order to provide the required cooling
capacity.
Another point
which requires consideration in
condenser selection is the necessity to assure
the adequacy of the design to provide the cooling capacity required in
conditions of high ambient
temperature. In periods where air temperatures are
low, operating all fans at maximum rotation to achieve the desired capacity
will be superfluous and costly. In systems monitored by
condenser pressure -
temperature, operating fans at low rotation or disabling them will provide an
air supply of sufficient flow to the system.
