Cooling function process
•
The warm interior air of the switch cabinet is blown by the fan (2) over the air/ water heat exchanger (1) and
cools off.
•
In correspondence with the selected setpoint temperature, a solenoid valve (3) regulates the cooling water flow
(4)/(5), and thus the cooling capacity. The cooled air is then diverted back into the ambient air.
•
Condensing water must be diverted through the condensate drain (6) and is collected in a
bottle. This condensate collecting bottle is available as an accessory from Pfannenberg.
