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.

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