High Energy Efficiency to Save Power Consumption

High Energy Efficiency to Save Power Consumption
For PAC Heatpump Inverter models, the coefficient of performance has been especially improved to reduce power consumption.
Note: Compare with 4-way cassette at same range capacity COP (2.5/3.0/4.0/5.0/6.0 HP).

Eco-Friendly R32 Refrigerant

Panasonic air conditioners are increasingly using the eco-friendly R32 refrigerant, an excellent energy- and cost-efficient heat transfer medium. With lower global warming potential, the R32 refrigerant is much more environmentally friendly.

High Durable Outdoor Unit

Stable Operation Even in Difficult Ambient Conditions

The operating range has been expanded to an outdoor air temperature of 43°C (cooling) / -15°C (heating). Hot air is discharged from the outdoor unit during cooling operation, and cold air is discharged from the outdoor unit during heating operation. Needless to say, if outdoor units are close together, the temperature at the place where the outdoor units have been installed will be harsher than the outside temperature. The PAC Heat Pump models continue to operate reliably even in the most difficult ambient conditions.
Stable Operation Even in Difficult Ambient Conditions

Prevents Unit Stoppages Due to Short Circuits Caused by Geckos

One of the common causes of failures of the outdoor unit is electrical short circuits caused by geckos entering the unit. The unit eliminates gaps that prevent geckos from entering the internal PCB and thus prevent operation stoppages.

Rust-resistant and Easy to Maintain

Panasonic heat exchangers feature Blue Fin technology to prevent corrosion and ensure long-lasting performance. Panasonic uses a copper tube condenser, which makes it easy to repair and maintain.
Note: Selecting this unit does not completely eliminate the possibility of rust developing. For details concerning unit installation and maintenance, please consult an authorised dealer.

Long Piping Allows Flexible Installation

Piping can be extended up to 30 m without additional gas charging, and up to 50 m with additional gas charging. Even in stores and offices where space is limited, outdoor units can be installed on rooftops and other places.
Note: Additional gas is required when the piping length is extended.
