Mechanical

(1)

Entering air 24°C/45% RH ambient 35°C.

(2)

Fan Gain / Fan power input based upon fan operating with design airflow at 25Pa ESP, these values may change with different ESP.

(3)

With Standard forward curved fan motors; Machine weight includes a refrigerant charge.

(4)

Backward curved EC fan options quote electrical power. All other options quote shaft power.

(5)

For refrigerant charges, refer to

Unit Refrigerant Charge (kg/Circuit)

.

(6)

Based on air temperature of 15.5°C leaving the evaporator coil.

(7)

Based upon low pressure hot water 82°C inlet / 71°C outlet. Air on 20°C. Refer to

Low Pressure Hot Water

.

Electrical

(1)

Values given for full function units (incl. electric heating, humidification and matched condenser) at 7°C evaporating and 54.4°C condensing with standard

forward curved fan motors, for optional data, please contact Airedale.

(2)

Values given for Cooling only units (incl. Compressor, evaporator fan and matched condenser) at 7°C evaporating and 54.4°C condensing, for optional

data, please contact Airedale.

(3)

Electrical input power relates to the maximum absorbed electrical power. Actual operating fan power input is shown in the mechanical data tables.
