Extended Operating Range

High Reliability Even Under High Temperature Conditions

Extended Operation Range Image Visual

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.

Extended Operation Up to 52℃

Designed to be durable enough to withstand extreme heat, FSV EX ensures reliable cooling operation over an extended operation range up to 52˚C.

Panasonic builds air conditioning systems not only with a high EER for rated operation, but also with Seasonal-EER appropriate to the customer’s actual environment of use. For instance, with rated operation, outdoor temperature is constant at 35℃, but in reality the outdoor temperature is continuously changing. Consequently, required air conditioning performance also changes. That’s why Panasonic implements the following kind of proprietary control.

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.
