Extraordinary Energy-Saving Performance
The operation efficiency has been improved using highly efficient R410A refrigerant, a new DC inverter compressor, and a new heat exchanger design.
Key Technologies for Excellent Energy Savings
Multiple Large-capacity All-Inverter Twin Compressors
Redesigned components in the body provide improved performance, especially in the rated cooling condition and COP performance. First, two independently controlled compressors achieve high efficiency (for more than 14 HP). Then, twin rotary compressors offer both low vibration and high COP.
Enlarged Heat Exchanger Surface Area
The new heat exchanger features a triple-surface construction. Compared to the divided dual-surface construction in current models, there is no division of space and the area for heat exchange is larger. Also, a highly efficient piping pattern increases heat exchange performance by 5%*. The condenser’s 3-row design improves the heat exchange efficiency by increasing the surface area.**
Note: For 8/10 HP units, the heat exchanger is 2-row design. *Based on Panasonic in-house report. **For 12/14/16/18/20 HP units.
Energy Saving and Comfortable Air Conditioning
Oil Management System for Energy Saving and Comfortable Air Conditioning
If it takes time to recover the oil moved to the IDU side, the cooling capability will be reduced. Panasonic VRF systems minimize the time and frequency of oil recovery by managing oil recovery in three stages, equipping units with sensors to detect oil levels, and using accumulators. This reduces energy consumption and maintains comfort without sacrificing cooling capability.
Variable Evaporation Temperature (VET) for Energy Saving and Comfortable Air conditioning
The indoor and outdoor units work in tandem to control evaporation temperature, refrigerant volume, and airflow. This enables optimal air conditioning according to the number of people in the room and the indoor temperature, as well as energy savings and comfort.
Note: When fan speed is set to Auto.
Demand Response Ready
Simple Demand Response
Featuring inverter control technology, ME2 series systems are Demand Response Management (DRM) ready. With this control, power consumption at times of peak load can be set in three steps to deliver optimum performance. This helps to correspond with the local power management for reducing peak power consumption, and to reduce annual power consumption with minimal loss in comfort.
*Demand controller. Relay contact point: No voltage relay.
**Current input is DC 24V 10mA Use a very small electric current contact point for the relay.
**Current input is DC 24V 10mA Use a very small electric current contact point for the relay.
Flexible Demand Response
It is possible to limit the operating current of ME2 series system to 3 stages (75%/50%/0%) according to the demand control signal sent from the building.
High Durability
Extended Operating Range
Cooling operation is possible even when the outdoor temperature is as low as -10°C DB or as high as 52°C DB. As for heating operation, it is possible even when the outdoor temperature is as low as -25°C WB. The remote controller temperature can be set from 18°C up to 30°C (cooling), 16°C up to 30°C (heating)*.
*Depending on the type of remote controller.
Note: Cooling/heating capacity depend on indoor/outdoor temperature. Please refer technical databook.

Rust-resistant and Easy to Maintain
Corrosion-resistance treated for exposure to rust to assure long-lasting performance. The anti-corrosion Blue Fin treatment of the heat exchanger provides greater resistance against corrosion. Specific models with suffix “E” have this treatment. (Blue Fin treatment is applied to the condenser of the heat exchanger on all models.) Panasonic also 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.
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.
Note: This construction does not completely eliminate the possibility of short-circuit faults in the circuit board.
Reliable Operation
Extended Compressor Life by Uniform Compressor Operation Time
The total run-time of compressors is monitored by a built-in microcomputer, which ensures that the operation times of all compressors within the same refrigerant circuit are balanced.* Compressors with histories showing shorter run times are selected first, ensuring equal wear and tear across all units and extending the working life of the system.**
*Depend on the accumulated operation time of each compressor. **Compressor priority can be changed. (e.g.) Case1: A->C->B->D, Case2: C->A->D->B, Case3: A->C->D->B, Case4: C->A->B->D
Automatic Backup Operation in the Case of Compressor Failure or Outdoor Unit Malfunction
Automatic backup operation works in the case of compressor failure or outdoor unit malfunction. Even if a whole outdoor unit fails, the other outdoor unit keeps running, and even if a compressor in a single system fails, the other compressor keeps running.
Note: Except for 8, 10 & 12 HP single unit installation. The backup operation allows uninterrupted cooling or heating to continue whilst waiting for service. Users should contact their authorised service centre as soon as a fault occurs.
