DESCRIPTION OF THE MACHINE
3.1 Main components and operating principle
The PAD-V adiabatic cooler is designed to exploit, in warmer seasons, the process of forced humidification of
ambient air, which allows temperatures to drop to values close to the "wet bulb" temperature.
The adiabatically cooled air strikes the finned tube heat exchange batteries, increasing efficiency, compared to
use with dry air.
Thanks to a submersible pump, fed by two equalisation tanks, the water reaches the wetting circuit, at the end
of which, once it has passed through the humidifier pack, it returns to the collection tanks.
This allows for short wetting cycles, at long intervals from each other.
When the minimum level sensor indicates that the water level in the tanks is insufficient for a new wetting cycle,
more water is drawn in through the make-up pipe.
Periodically the tanks are emptied and the water in the wetting circuit is almost completely changed.
The machine is also equipped with an electrical panel for complete and automated management of operation
both in DRY and WET (adiabatic) mode.
The operating conditions of the PAD-V, based on the characteristics of the individual model, must always comply
with the technical operating data shown on the CE data plate on board the individual machine. This CE data
plate also indicates the PAD-V model; the meaning of the relative code is shown in the following figure.
