3.1

Wide application

The Sinclair small outdoor unit is a highly efficient solution

for small commercial buildings requiring heating

and cooling of up to 7

zones

with one outdoor unit. Such as villa, restaurant, school

etc.

Sinclair offers a variety indoor unit, more than 40 models of 7 types. Capacity ranges are from 2.2kW

to 16

kW. It is full compliance with residential and light commercial place.

Our systems can operate up to 130% of

capacity which allows any system to be designed to the customers and applications needs.

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.

3.7

Flexible piping design

3.8

Flexible indoor unit’s connection

Small outdoor unit with intelligent control gives you independent zoning control with maximum flexibility.

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.
