3.2
High efficient
DC inverter compressor
Sinclair small outdoor units adopt
highly intelligent inverter-driven compressor. This advanced technology enables the output of
the outdoor unit to be modulated by the real heat load demands. This advanced system ensures precise temperature
regulation and highly efficient energy usage, making a
significant contribution to the limiting the impact on
the
environment.
3.3 High performance heat exchanger
The new designed window fins enlarge the heat-exchanging area,
which decrease the air resistance, save more power and enhance heat
exchange performance.
Hydrophilic film fins and inner-threaded copper pipes optimize heat
exchange efficiency.
3.4 Low-operating sound design
Optimally design fan shape and new designed discharge air grille and air deflector, making higher air volume
and lower operation sound.
3.5 Quick warm-up & cool-down design and less temperature fluctuation
Utilizing the inverter compressor benefits,
the system can reach full load quickly and
shorten warm-up or cool-down time for an
immediate comfortable air solution.
Less temperature fluctuation will create a
better living environment. Used across entire range of models.
Efficiency improvement by up to 45% especially at low speed.

Wide operation temperature range
No matter in extremely cold winter when outdoor
temperature gets as low as -15°C or in hot summer
when
temperature is up to 48°C, the small outdoor
unit will keep stable performance.

Flexible indoor unit’s connection
Small outdoor unit with intelligent control gives you independent zoning control with maximum flexibility.
A
single outdoor unit supports up to
nine
indoor units, freeing up considerable space outside. Use your
backyard more wisely with much more space available created by less number of outdoor units.
Max. 9
indoor units for a 18kW outdoor unit installation
3.9
Simple signal line connection
Installation is much easier as the communication wiring between indoor & outdoor units can be shared.
It’s easy for the user to retrofit the existing system with a centralized control by simply connecting to
outdoor units.
3.10 Auto address setting function
The addresses of indoor units can be set automatically by outdoor unit.
Wired controller and wireless controller can enquire and modify the address of each indoor unit.
