Features
High External Static Pressure 35Pa
When unit is installed on a narrow balcony and exposed to the sun, the fence at the front side would restrict hot air from being discharged. Heat accumulated in an enclosure can cause over-heating. This could potentially result in damage or shorten the product’s life span. A high external static pressure sends the air further away from the outdoor unit and through the fence. This provides better air circulation and distribution.
Pressure is higher than previous model
When the pressure is low, hot air will accumulate in the unit thus affecting its work performance and of the unit above it as well.
But with a high pressure of 35Pa, hot air is sent further away preventing overheating inside the outdoor unit enclosure.
The new fan can discharge the hot air efficiently
High electrostatic pressure disrupted the airflow of the previous fan, lowering the air pressure and preventing hot air from being discharged far enough.
The new LE Series fan has ribs extending near the blade tips, in a structure that resists deformation. During high electrostatic pressure, this blade shape suppresses disruptions in the airflow, and a high air pressure of 35 Pa discharges the hot air a sufficient distance.
Variable Evaporation Temperature for Energy Saving and
Comfortable Air Conditioning
Since 2006, all Panasonic VRF systems have included special VET technology, with variable refrigerant temperature, as standard.
Our ‘smart logic’ system checks the temperature every 30 seconds, automatically adjusting the refrigerant temperature according to actual demand and outdoor conditions.
1) Feedback room temperature and set temperature every 30 seconds
2) Determine system refrigerant temperature and control compressor speed.
3) Calculate indoor refrigerant temperature and control the airflow automatically based on the difference between the setting temperature and actual indoor temperature.
* When fan speed is Auto.
Room-by-room Comfort and Overall System Energy Savings
1) Outdoor control
The evaporation temperature information required for all indoor units in the system is consolidated for optimal refrigerant temperature control.
2) Indoor control
Based on the suction temperature, the amount of circulation refrigerant volume required for the cooling load is controlled by the expansion valve of each indoor unit.
Low Cooling Load Area : Energy Savings
1) Refrigerant evaporation temp. : High
2) Circulation refrigerant volume : Less
3) Indoor unit discharge temp. : High
4) Indoor unit air flow : Low
High Cooling Load Area : Comfortable Cooling
1) Refrigerant evaporation temp. : Low
2) Circulation refrigerant volume : Many
3) Indoor unit discharge temp. : Low
4) Indoor unit air flow : Powerful
Combination of VET technology and inverter compressor for both energy savings and comfort
Long Piping Design Length for Greater Design Flexibility
Adaptable to various building types and sizes
Max. total piping length:300m
LE1-1 Actual piping length 150m (equivalent piping length 175m)
LE1-2 Height difference 50m*¹
LE1-3 Level difference between indoor units 15m
*1 40m if the outdoor unit is below the indoor unit.
Max. total piping length:180m
LE2-1 Actual piping length 150m (equivalent piping length 175m)
LE2-2 Height difference 50m*¹
LE2-3 Level difference between indoor units 15m
*1 40m if the outdoor unit is below the indoor unit.
Refrigerant Chargeless Up to 50m (LE2 only)
Up to 50m* of piping without additional gas charging makes installation flexible, easy and hassle-free.
* A 50m pipe length is sufficient for most residential and small business buildings. When total piping length exceeds 50m, additional refrigerant charge is required.
Chargeless (Max. total piping length: 50m)
Charge (Max. total piping length: 180m*)
* Actual length: 150m
Compact Design
Since Mini VRF LE Series is a single unit, it is possible to install the unit in more various places compared to the Single Split system.
Short Height of 996mm (LE2 only)
In addition to raising efficiency, we have made the outdoor unit more compact. It can now be installed in places that were previously too small.
Up to 13 Indoor Units Connectable
An expansion from Panasonic VRF line up, the Mini FSV is compatible with the same indoor units and controls as the rest of the FSV range.
* Use any of the 22 type indoor models. Depending on the size or type of indoor unit, tubing size shall be changed. Please refer manuals for details.
* Diversity ratio 50-130%
* 6 HP only; 4 HP for 7 units, 5 HP for 8 units.
High Efficiency
The operation efficiency has been improved using highly efficient R410A refrigerant, a DC Inverter compressor, DC motor and a heat exchanger design.
Energy Savings Design
1. Panasonic’s Inverter Compressor to improve partial-load capacity.
2. 2 pieces 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 to increase efficiency.
6. Redesigned Heat Exchanger &Copper Tubes to increase efficiency.
7. Centrifugal Oil Separator improve oil separation efficiency and reduce refrigerant pressure loss.
Flexible Demand Response with the Optional Terminal Block (CZ-CAPDC2)
Featuring inverter control technology, all Panasonic Mini FSV 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 reduce annual power consumption with minimal loss in comfort.
*Terminal block parts to be supplied separately. Please ask your dealer
Setting is possible as 0% or in the range from 40 to 100% (in steps of 5%). At the time of shipping, setting has been done to the three steps of 0%, 70% and 100%.
* Demand timer setting for high spec remote controller is available.
Wide Operating Range
Cooling operation is possible even when outdoor tempature is as low as -10°C DB or as high as 46°C DB. As for heating operation, it is possible even when 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)*¹.
*1 Depending on the type of remote controller.
* For further information please refer to the capacity tables in the Technical Data Book.
Blue Fin Condenser
The anti-corrosion Blue Fin treatment of the heat exchanger provides greater resistance against corrosion. All models are equipped with Blue Fin condenser.
High Durability Outdoor Unit
Corrosion-resistance treated for high resistance to rust and salty air to assure long-lasting performance.
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.
* Specific model with suffix “E” has this treatment.
Quiet Operation Mode
• Quiet operation mode reduces outdoor unit operating sound down to 7dB than rating.
• 3-step set point is available.
• External input signal is also available.
*Note: Quiet Operation Mode timer setting is available with high-spec Remote Controller (CZ-RTC5B).
