Panasonic Mini ECOi LZ2 Heat Pump Systems R32

For small-scale commercial and residential use

2-Pipe Mini-VRF LZ Series

The Mini-VRF LZ Series is designed for light commercial and residential use with extraordinary energy-saving performance and a high external static pressure of 35 Pa.

The most flexible VRF system ever. Meeting the needs of light commercial applications. Industry 1st: 8 and 10HP Mini VRF units with R32.

Key features

Low GWP and less refrigerant

Low GWP and less refrigerant

The new Mini ECOi LZ2 Series utilises environmentally friendly R32 refrigerant, reducing the total amount of refrigerant by 20% and more, resulting in lower GWP, reduced by 75%*.

* As a result of applying R32 while at the same time reducing the total refrigerant amount.

Outstanding efficiency at most challenging ambient conditions

Outstanding efficiency at most challenging ambient conditions

Re-engineered for better performance, the LZ2 series produces extraordinary savings with SEER levels up to 8,5 and SCOP levels up to 5,05 (for the 4HP model). The large range of outdoor units from 12kW to 28kW can also work at extreme ambient temperatures, down to -20°C in heating and up to 52°C in cooling, providing a very wide range of operating ability.

More flexibility for your project

More flexibility for your project

The ECOi LZ2 series provides ease of installation with long piping lengths and small footprints in a lightweight body. A variety of indoor units, supporting Panasonic’s optional refrigerant leak detector, increases the flexibility for installers. A wide range of individual and central controllers, the new generation Smart and Service Cloud as well as apps for end users and installers provide a fully customisable monitoring and controlling solution.

Extraordinary Energy-Saving Performance

The operation efficiency has been improved using a highly efficient R32 refrigerant, a DC Inverter compressor, a DC motor, and a heat exchanger design.

Energy Savings Design

  1. Panasonic’s inverter compressor to improve partial-load capacity.
  2. 2 pieces of the printed circuit board for easy maintenance.
  3. Large-size accumulator to maintain compressor reliability for extended max piping length.
  4. DC fan motor for optimum air volume.
  5. Newly designed fan blades to inhibit air turbulence and increase efficiency.
  6. Redesigned heat exchanger & copper tubes to increase efficiency.
  7. Centrifugal oil separator improves oil separation efficiency and reduces refrigerant pressure loss.

Highly Flexible Installation and Design

  • Maximum total piping length 180 m (12.1/14.0/15.5 kW) / 300 m (22.4/28.0 kW)
  • Actual piping length 90 m (12.1/14.0/15.5 kW) / 100 m (22.4/28.0 kW)
  • Elevation difference of maximum 50 m in case of outdoor unit is higher than indoor unit.
  • Maximum 15 meters height difference between indoor units.
  • Up to 13 indoor units connectable in case of 22.4/28.0 kW.
  • High external static pressure of 35 Pa.
  • Demand response is capable with additional demand terminal kit CZ-CAPDC3.

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.

Wide 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 -20°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

The anti-corrosion Blue Fin treatment of the heat exchanger provides greater resistance against corrosion. Panasonic also uses a copper tube condenser, which makes it easy to repair and maintain. All models are equipped with Blue Fin condenser.

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.
