InRoom CW/DX – Operating Instructions24
4.1 Application limits
The InRoom precision air conditioning units operate
within the following ranges:
- Room Conditions:
Between 18°C (64°F), 40% Relative Humidity
(R.H.), and 27°C (81°F), 55% R.H.
- Outdoor ambient conditions:
Lower limit: -10°C (14°F)
Upper limit: Depending on selected condenser
- Voltage:
460V / 3ph / 60 Hz
208-230V / 3ph / 60 Hz
- Voltage tolerance: +/- 10%
- Voltage imbalance: <3%
- Frequency:60 Hz +/- 1%
- Chilled water-/cooling water pipes:
Maximum water head pressure: 10 bar (145 psi)
- Maximum equivalent length of piping between the
cooling unit and the air cooled condenser: 60 m
(200 ft)
- Maximum level difference between the condenser
and the cooling unit: 5 m (16 ft) when the condenser
is below the cooling unit.
- Storage conditions:
Temperature: -20 - +42°C (-4 - +107.6°F)
Humidity (% R. H.): 5 – 95
Atmospheric pressure: 70 - 110 kPa (10 - 16 psi)
The warranty is invalidated for any possible damage
or malfunction that may occur during or in conse-
quence of operation outside the application ranges.
Design conditions for technical data:
Return air conditions for evaporator capacity (DX): 24°C (75°F) 50% R. H.
Return air conditions for cooling capacity (CW): 24°C (75°F) 50% R.H.
Entering water temperature (EWT) for CW coil: 7°C (44.6°F)
Leaving water temperature (LWT) for CW coil: 12°C (53.6°F)
Condensing temperature: 45°C (113°F)
Maximum condensing temperature: 60°C (140°F)
Cooling fl uid (DX): 30% Glycol
Fluid inlet temperature (G): 30°C (86°F)
Fluid outlet temperature (G): 40°C (104°F)
Chilled water medium (CW): 0% Glycol
Data is valid for: 460V / 3ph /60 Hz
Downfl ow units with an external static pressure: 20 Pa (0.08 in w g)
Upfl ow units with an external static pressure: 50 Pa (0.20 in w g)
The sound pressure levels are valid at a height of 1m (3.3 ft) and distance of 2m (6.6 ft) in front of the unit
under free fi eld conditions and with no mi nal data. The values take into account the effects of all installation
and design parts contained in the standard unit.
