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.

Chigo offers various indoor units, more than 100 models of 11 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 optimize heat

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 with DC fan motor and

world-famous compressor, making higher air volume and lower operation sound.

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 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.

Highly Efficient DC Motor:

-Creative motor core design

-High density neodymium magnet

-Concentrated type stator

-Wider operating frequency range

Better balance and Extremely Low Vibration:

-Twin eccentric cams

-2 balance weights

Highly Stable Moving Parts:

-Optimal material matching rollers and vanes

-Optimize compressor drive technology

-Highly robust bearings

-Compact structure
