3-PIPE FSV-EX MF3 Series Enables Simultaneous Heating and Cooling Operation

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.

The FSV-EX Series

Excellent Energy Savings

The operation efficiency has been improved using highly efficient R410A refrigerant, new DC inverter compressor, and new heat exchanger 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.

Intelligent 3-Stage Oil Management System

The Panasonic System Efficiently Manages Oil Recovery in Three Stages

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

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.

STAGE-2

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

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

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.

Newly Designed Fan

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.

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 Operating Range

Cooling operation is possible even when 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 outdoor temperature as low as -20°C WB. The remote controller temperature can be set from 16°C up to 30°C*.

* Depending on the type of remote controller.

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

System example [Case1]

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.

Blue Fin Condenser Outdoor Unit

The anti-corrosion Blue Fin treatment of the heat exchanger provides greater resistance against corrosion. All models are equipped with Blue Fin condenser.

Blue Fin Condenser Outdoor Unit

Long Piping Design

Adaptable to various building types and sizes
Actual piping length : 200m
Max piping length : 500m

*Elevation difference of Max. 50m in case of ODU is higher than IDU may be allowed following certain conditions. Please consult with Panasonic sales engineers about the certain conditions in case of piping elevation of over 50m is required.
*1: 40 m if the outdoor unit is below the indoor unit.

Long Piping Design

Up to 40m Piping after First Branch

Up to 52 units can be connected to one system. Flexible piping layout makes it easier to design systems for locations such as train stations, airports, schools and hospitals.

Up to 40m Piping after First Branch

Increased Max. Number of Connectable Indoor Units

The 3-PIPE MF3 series has four DC inverter outdoor units from 8HP to 16HP as the basic models, and by combination of up to three units, an air-conditioning capacity of 8HP to 48HP can be set according to the user needs.

*Connectable indoor/outdoor unit capacity ratio up to 150%

High External Static Pressure on Condensers

With a newly designed fan, fan guard, motor, and casing, new models can be custom-installed on-site to provide up to 80 Pa of external static pressure. An air discharge duct prevents shortages of air circulation, allowing outdoor units to be installed on every floor of a building.

Fan and Fan Motor and Casing, High Static Pressure 80 Pa

Low-Noise Operation

Numerous technological innovations, including an improved compressor and a newly designed bell mouth and larger fan, have dramatically reduced the outdoor noise level. The result is an even more comfortable building environment.
