8. MECHANICAL DESIGN, OPERATING PRINCIPLES AND COMPONENTS.
(Recirculated water with stage control)
MECHANICAL DESIGN
The humidifier is composed of the following elements:
•
A stainless steel self-supporting chassis-water tank structure that houses the unit.
•
A set of evaporative panels of variable sizes and thicknesses, depending on the model and stainless steel
surround.
•
A stainless steel float valve automatic control mechanism for the network water supply, to maintain the
appropriate level in the water tank, so the unit works correctly. This valve can be regulated in order to set
it to the available water pressure in the network.
•
A stainless steel water tank to hold the water, which is designed so it can be completely emptied by gravity.
•
A pump for supplying water from the water tank to the evaporative panels (technical data on chapter 9.2.C).
•
A stainless steel mechanism integrated into the water tank acting as an overflow for the system in the
event of water level control faults.
•
The stages are controlled by opening the N.C. solenoid valve of each stage.
•
A distribution collector + regulation valves with flow meter set to supply the appropriate irrigation
individually to the evaporative panels.
•
A diversion from the water flow to the distribution collector regulates a constant flow of water, which is
eliminated from the system in order to maintain a uniform amount of mineral salts in the irrigation water,
which we will refer to as th
e “Constant bleed-off system”. (See page 36).
Remark: Each stage can include the irrigation of more than one cassette. The configuration of stages
is variable and defined by the client.
DROPLET SEPARATOR
Operating conditions giving rise to droplet carry-over, can be handled by adding a second PP profile panel to
the humidifiers to capture the droplets being detached from the evaporative panel.
