3.3.1 Parameters and general considerations
Correct operation of the evaporative cooling tower is also dependent upon the observance of several rules of a
general nature but of fundamental importance, to which it is advisable to adhere already in the phase of choice
of the place for installation of the equipment.
In summary, these rules are the following:
-
The cooling tower must always be installed outside , so far as possible in a well-aerated position and
such as to respect a minimum distance (at least equivalent to the size of an air intake) from walls and
buildings. Whether or not it is placed in a very sunny spot has no influence upon the thermal performance of
the unit. Only in special cases and respecting very precise indications that can be provided by MITA’s
technical dept., can one consider the possibility of a different form of installation;
- avoid totally and absolutely making roofing, screening, ductwork or other impediment to the correct
and free circulation of air to, from and within the tower. Moreover be particularly careful about the possible
presence of prevailing winds and that eventual “down-wind” situations cannot give rise to air recirculation on
the tower [Fig. 06];

- The cooling tower must be installed as far as is possible away from zones usually occupied by
persons, from open windows or from air-intakes to buildings
;
- avoid siting the tower under a roof or covering: the resultant impedance to the free discharge of the
outlet air, which is thus created, may be cause of recirculation of that same air which, having a saturation
humidity, penalizes in a significant manner the tower’s thermal performance;
- avoid siting the tower under or near to trees: above all in the Autumn, the falling leaves might be drawn
in by the fans, finishing in the hydraulic circuit and creating serious problems for the pumps and in the
cooling circuit in general;
- In the case of installations in small courtyards or in restricted spaces , be particularly careful about the
orientation of the tower and about the remaining space available around it both for unrestricted airflow, and
for allowing installation of the piping and eventual maintenance operations.
