internal exchanger water = 12/7°C
difference between inlet / outlet water temperature = 5°C
Warning: the still air condition is meant as absence of air flow to
the unit. Any wind condition
can let air pass through the condenser coil thus worsening the
operating limits of the unit
(see limits with air speed at 0,5 m/s & 1 m/s).
Note: the Standard unit shall never be exposed, at temperatures
below -10°C while
supplied. On request it’s possible to take countermeasures for
the operation also in more
critical environmental conditions. For special conditions contact
our Sales Office.
ATTENTION: IN CASE OF PREDOMINANT WINDS,
WINDBREAK BARRIERS ARE NECESSARY.
(1) unit at full load
(2) Max inlet air temperature - capacity-controlled unit with standard limit device
(3) Min inlet air temperature - unit at full load and motionless ambient air
(4) Min inlet air temperature - unit at partial load and motionless ambient air
(5) Min inlet air temperature - unit at partial load and air speed of 0.5 m/s.
(6) Min inlet air temperature - unit at partial load and air speed of 1 m/s.
(7) standard unit
(8) B = Low Temperature.
