Maximum allowed air volume flow
under "Standard conditions"
1 Air intake temperature entering the AHU DX coil heat exchanger
2 Special conditions A: Using an AHU unit with a higher maximum allowed air volume flow is subject to a restriction of the
"Air intake temperature" to 30 °C DB (instead of 32 °C WB under standard conditions).
3 Special conditions B: Using an AHU DX coil heat exchanger with a larger volume is subject to the following restrictions:
●
●
●
Note: The AHU DX coil must be designed according to Panasonic specification.
Calculation example for total additional refrigerant charge (R32)
Unit: U-60PZ2E5
Pipe length: 40 metres
AHU DX coil (supplied by AHU manufacturer): 1,7 dm
Refrigerant charge at shipment fitted for pipe length within 30 m
Pipes additional refrigerant charge: 0.035 kg/m
