YORK ® AIR-CONDITIONING PRODUCTS
Indirect free cooling with adiabatic cooling Available accessories
The indirect FREE COOLING system with adiabatic cooling
includes both the technology of air-to-air heat recovery and that of
adiabatic cooling, in which some water is evaporated to cool down
outside air. Direct expansion:
• Direct expansion, supplementary post cooling circuit with DC inverter
compressors
• Power supply line for remote condenser
• Power supply line with speed regulator for remote condenser
• Condensing regulation with 0-10V signal for remote condenser with
EC fans
• “LT Kit” for operation with low temperature outside air with remote
condenser
• Oversize liquid receiver
• Check valves on the supply and liquid pipes
• Water-cooled condenser
• Water-cooled condenser with a condensing temperature adjustment
valve
• “HT Kit” for operation at high condensing temperatures
Being able to exploit the FREE COOLING system even at
temperatures of 30°C/35%Rh, these units achieve very high
energy efficiency, offering energy savings of up to 80%
compared to a comparative to a mechanical cooling system.
An innovative evaporative panel
In order to maximise the system efficiency, an innovative evaporative
panel is used that allows saturation efficiency greater than 90%
using more than 60% less water.
Thanks to the OXYVAP ® system, formed by special formed and
treated aluminium fins, it is possible to:
Chilled water:
• Chilled water, supplementary post cooling circuit with adjustment
two-way valve
• Three-way control valves
• Inlet and outlet water temperature sensors
• “Power valve” kit
• Use drinkable water. No expensive water demineralisation systems
are required.
• Cut down on water consumption. Over 60% water reduction with
respect to conventional evaporative panels and spraying systems.
• Eliminate the risk of mould, algae and pathogenic organism
formation. The surface treatment of aluminium fins and the absence
of a collection and water circulation tank eliminates the risk of
pathogenic organism formation.
