Extraordinary Energy-Saving Performance

The FSV-EX marks a revolutionary step forward in VRF efficiency. A look at the incredible EER value clearly indicates that. What’s more, this high EER value is achieved even during part load operation. This shows the extraordinary energy-saving performance the FSV-EX is capable of providing.

1. Multiple large-capacity all inverter compressors (more than 14HP)
Two independently controlled inverter compressors achieve high efficiency. Redesigned components in the body provide performance improvement especially in the rated cooling condition and EER performance.

2. Enlarged heat exchanger surface area with triple surface*
The new heat exchanger features a triple-surface construction. Compared to the divided dualsurface construction in current models, there is no division of space and the area for heat exchange is larger. Also, highly efficient piping pattern increases heat exchange performance by 5%

* For 8 & 10HP unit, the heat exchanger is 2 row design.

Intelligent 3-Stage Oil Management System

In a VRF system, where lengthy piping and a large number of indoor units need to be controlled collectively, the key to maintaining the system’s reliability is to ensure an appropriate amount of oil is secured in the compressors. In order to avoid oil shortage in the compressor, maximum operation is normally forcibly conducted at regular intervals to recover oil from indoor units. This method, typically employed in a standard VRF, causes the system to overheat or overcool and thus waste energy. In Panasonic VRF systems, a sensor for detecting oil levels is mounted in each compressor. In installations with multiple outdoor units, a shortage of oil in one compressor can be compensated for by recovering oil either from another compressor in the same unit, from a compressor in an adjacent outdoor unit, or from a connected indoor unit. Panasonic VRF systems provide users with a comfortable environment whilst saving energy.

The Panasonic System Efficiently Manages Oil Recovery in Three Stages

Minimising the frequency of forced oil recovery while reducing energy cost and maintaining comfort.

Image: STAGE-1

Panasonic compressors are equipped with sensors which monitor oil levels precisely at all times. If oil levels fall, oil can be transferred from other compressors within the same outdoor unit.

Image: STAGE-2

If oil levels in all compressors within the outdoor unit fall, oil can be replenished from adjacent outdoor units.

Image: STAGE-3

Forced oil recovery is implemented only if oil levels become insufficient in spite of above measures. The Panasonic system’s design concept is radically different from conventional oil systems.

Features of 3-Stage Oil Recovery Design

Image: Features of 3-Stage Oil Recovery Design

1. Oil sensors installed in each compressor
Oil sensors installed in each Panasonic compressor precisely monitor oil levels, eliminating unnecessary oil recovery.

2. Highly functional oil separator
Thanks to extended separate piping, oil recovery efficiency reaches 90%, minimising the oil to be discharged from the compressor.

A : Minimum oil level (Surface of rotary cylinder)
B : In Panasonic VRF systems, a sensor for detecting oil levels is installed in each compressor.

Redesigned for Smooth and Better Air Discharge

1. Newly designed curved air discharge bell mouth for better aerodynamics
The new curved shape with integrated top and bottom assure smooth exhaust flow. This gives more air-volume with same sound level, less power input at same air-volume.

2. Large air discharge area with new flush surface top panel
To reduce air resistance, instead of a tubular fan design, a new large flat fan guard design, flush with the top panel, is employed. This design lead to the improvements in air resistance, but also contributed to better appearance designing.

Newly Designed Fan

Image: Optimised air flow

Optimised air flow

Newly designed fan and bell-mouth reduces stress on the fan by dispersing air quickly. Thus, lower air resistance results in lower energy consumption.

Image: Noise reduction

Noise reduction

Turbulence (blue) can be suppressed and the unwanted noise can be reduced. Even though a high speed fan is utilised, the noise level is still very low.

Extended Operation Range Up to 52°C

The FSV-EX can provide cooling even when the outside temperature reaches a maximum of about 52°C. And amazingly, it can still operate at 100% capacity when the outside temperature is as high as 43°C. This high power capability enables reliable operation even under extremely high temperature conditions.

Image: Extended Operation Range Up to 52°C

Extended Operating Range

Cooling operation is possible even when outdoor tempature is as low as -10°C DB or as high as 52°C DB. As for heating operation, it is possible even when outdoor temperature 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.

Image: Extended Operating Range

Extended Compressor Life by Uniform Compressor Operation Time

The total run-time of compressors are monitored by a built-in microcomputer, which ensures that 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 extended the working life of the system.

* Depend on accumulated operation time of each compressors.
* Compressor priority has possibility to be changed.
(e.g) Case1: AgCgBgD, Case2: CgAgDgB, Case3: AgCgDgB, Case4: CgAgBgD

Automatic Backup Operation

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.
Except for 8, 10 & 12 HP single unit installation

*Backup operation allows uninterrupted cooling or heating to continue whilst waiting for service. Users should contact their authorised service centre as soon as fault occurs.
