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.
