SAVING ENERGY WITH ADVANCED
REFRIGERATION CIRCUIT DESIGN
R410A refrigerant
Effi cient systems such as FLEXAIR are designed around R410A
refrigerant to achieve the best performances.
• Energy effi cient refrigerant thanks with pressure drop in the
pipes: Higher evaporating pressure and lower condensing
pressure improve compressor EER & COP.
• R410A compressors have a better isentropic effi ciency.
• Environmentally friendly refrigerant:
It contains No Chlorine (ODP =0). Signifi cant refrigerant charge
reduction (-40%) that limits the global warming potential of the
system. R410A optimized heat exchangers use less material
(copper, aluminum …)
1- GENERAL DESCRIPTION
1.4. MULTISCROLL COMPRESSOR
TECHNOLOGY
FLEXAIR units are provided with tandem compressors, to profi t
from the multiscroll compressor technology and giving the highest
seasonal performance and the best SEER coeffi cients.
High effi ciency multiscroll technology
Air conditioning equipments are sized to cover the need for the
most critical weather conditions which most likely will occur only
a few days or even a few hours during the year.
Most of the time, in Europe, the external temperature drops below
the reference value and consequently systems usually run 96%
of the time at part load. It is therefore important to design system
around part load performance to achieve the lowest possible
annual energy consumption.
FLEXAIR provides high effi ciency and best possible part load
effi ciencies year round with high effi ciency multiscroll R410A
compressor technology.
