Panasonic expands VRF range

Panasonic has expanded its range of low carbon VRF 3 way heating and cooling solutions, with claimed highest COP (Coefficient of Performance) of 4.77 at full load.

Panasonic’s new VRF 3 way range covers the full ECOi series, with two line-ups available:

- standard versions with COP up to 4,77 (at 100 per cent load)
- high cop version on key combination

The improvements include increased piping length which can be adapted to a variety of building types and sizes to a maximum of 180m from the outdoor unit to the furthest indoor unit.

The operating range has also been extended for both cooling and heating functions. By changing the outdoor fan to an inverter the cooling range has been extended by -10 deg c and using a compressor with a high pressure vessel, has seen an increase in the heating range even with an outside temperature of -20 deg c.

OPTIMISED EFFICIENCY
Efficiency across the range has been improved. For example, the 8HP unit offers an excellent COP (Coefficient of Performance) of 4.77 and an ERR (Energy Efficiency Ratio) of 4.5.

IMPROVED PERFORMANCE
Key product features of the new range include:
• Works with a maximum capacity ratio of 150 per cent.
• Can connect up to 52 indoor units.
• It has a static pressure of 80 Pa.

Other key features of the new three pipe series include selective defrost across multiple outdoor units (without adversely affecting indoor unit performance. In addition it’s claimed they require significantly lower quantities of refrigerant than other manufacturers.

The new heat recovery boxes are more compact and easier to install and help to support a comprehensive line up. The noise level is also reduce allowing it to be installed almost everywhere.
