SUPER PERFORMANCE THANKS
TO THE INVERTER PRINCIPLE
The coecient of performance (COP) of the Daikin Altherma
heat pump is also largely attributable to the Daikin inverter
principle. An integrated frequency-convertor adjusts the
rotational speed of the compressor to suit the heating
demand. Therefore, the system seldom operates at full
capacity and your customer only pays for the energy which
he actually needs.
HEAT EXCHANGER
ANTICORROSION TREATMENT
As a standard, the heat exchanger in the outdoor group is
provided with an anti-corrosion treatment. This treatment
guarantees a noticeable increase in resistance against acid
rain and salt corrosion.
Typical heat exchanger
Aluminium
Hydrophilic layer
Corrosion-resistant acrylate resin
HIGH EFFICIENCY COMPRESSORS
OUTDOOR UNIT:
STANDARD TO 20 OUTSIDE TEMPERATURE
The Daikin developed scroll-compressors
provided in the Daikin Altherma large capacity
models (11 to 16 kW) are designed as compact,
robust, low-noise devices to guarantee optimal
operational reliability (no valves and built-in
swing-link coupling) and eciency (through
a low initial ow and a constant compression
ratio). A technology already used in many
Daikin heat pumps.
Daikin Altherma small capacity models
(6 to 8 kW ) are equipped with a swing-
compressor. Swing-compressors have
been setting trends in the area of energy
ecient performance for the past 10 years
in thousands of outdoor units (leaks and
friction are basically non-existent).
