5. Features
5.1 Wide application
The All DC Inverter Mini VRF system is a highly efficient solution for small commercial buildings requiring heating and
cooling of up to 9 zones with one outdoor unit. Such as villa, restaurant, school etc.
GCHV offers various indoor units, more than 100 models of 10 types. Capacity ranges are from 2.2kW to 16kW.It is all
compliance with residential and light commercial place. Our systems can be operated up to 130%of capacity which
allows any system to be designed to the customers’ and applications’ needs.

Compressor
(Twin Rotary)structure
5.3 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-grooved copper pipes optimizeheat
exchange efficiency.
5.5 Quick warm-up & cool-down design and less temperature fluctuation
Utilizing the inverter compressor benefits,
the system can reach All 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.
5.4 Low-operating sound design
Optimally design fan shape and new designed discharge air grille and air deflector, auxiliary withDC fan motor and
world-famous compressor, making higher air volume and lower operationsound.
5.2 High efficient DC inverter compressor
All DC inverter Mini VRF adopts highly intelligent inverter-driven compressor. This advanced technology enables the
output of the outdoor unit to be modulated by the real heat loaddemands.
This advanced system ensures precise temperature regulation and highly efficient energy usage, making a significant
contribution to the limiting the impact on the environment.
Highly Efficient DCMotor:
- Creative motor core design
- High density neodymiummagnet
- Concentrated type stator
- Wider operating frequencyrange
Better balance and Extremely LowVibration:
- Twin eccentric cams
-2 balance weights
Highly Stable Moving Parts:
- Optimal material matching rollers and vanes
- Optimize compressor drivetechnology
- Highly robust bearings
- Compactstructure

5.6 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 55°C, the Mini VRF system
will keep stable performance.

5.8 Auto address setting function
The addresses of indoor units can be set automatically by outdoor unit. It has capability to reduce artificial faults and
manual works.
Wireless or wired controller can enquire and modify the address of each indoor unit.

5.9 Smart electronic control design
The radiation fin is made of aluminum panels fitting together seamlessly. This helps to cool down the IPM, it has better
performance compared to air cooling for PCB.
With PFC(Power Factor Corrector) module, the power utilization rate is increased, the power factor is capable to be 98%,
lead to higher efficiency.

5.10 Easy installation
The Mini VRF can be transported by elevator which makes
installation dramatically easy, and effectively reduces time and
labor thanksto the small size.
The Mini VRF units are more compact, resulting in significant
savings in installation space. It is particularly suitable for small
offices, villas, shops,etc.
5.11 Easy maintenance
Forced cooling button makes outdoor unit run in cooling mode at any
condition, so it is very easy for you to charge refrigerant to the system
when it needs to be done. The self-diagnosis function detects
malfunctions in major locations in the system and displays the type of
malfunction and location. This allows service and maintenance to be
performed moreefficiently.

1. The cooling conditions: indoor side 27°C(80.6°F) DB, 19°C(60°F)WB outdoor side 35°C(95°F) DB.
2. The heating conditions: indoor side 20°C(68°F) DB, 15°C(44.6°F)WB outdoor side 7°C(42.8°F)DB.
3.Sound level: measured at a point 1 m in front of the unit at a height of 1.5 m. During actual operation, these values are normally somewhat higher
as a result of ambient conditions.

Oil separator: It is used to separate oil from high pressure & temperature gas refrigerant that is pumped out from
compressor. The separation efficiency is up to 99%, it makes the oil return back to each compressor very soon.
Gas-liquid separator: It is used to store the liquid refrigerant and oil, it can protect the compressor from liquid hammer.
4-way valve: Closed in cooling mode and open in heatingmode.
Electronic expansion valve: The opening is of the valve is regulated according to the discharge air temperature of
compressor, used to regulating refrigerantflow.
High Pressure Switch: When the discharge pressure of compressor is 4.5Mpa or higher, the protection
switch will be triggered, and if the discharge pressure is down to 3.5MPa, the protection switch will be recovered.
Low Pressure Switch: When the gas pressure back to compressor is 0.05Mpa or lower, the protection switch will be
triggered, and if the discharge pressure is down to 0.15MPa, the protection switch will be recovered.
