CW CHILLED WATER UNITS
The CW uses the availability of chilled water to control the room conditions.
This version of LEONARDO has a relatively simple construction and
gives outstanding reliability.
The microprocessor controls the modulating action of the 3 way (or op-
tional 2 way) chilled water valve to give accurate control.
Careful sizing of the heat exchanger coils allows a high sensible to total
cooling ratio under most operating conditions.
Operating description
(*) Based on 24°C@50% air temperature, ESP=20Pa, chilled water 7/12°C, ethylene glycol 0%
(**) Based on 24°C@50% air temperature, ESP=20Pa, chilled water 10/15°C, ethylene glycol 0%
