Introduction of OlyAir VRF System air conditioner

VRF systemis well flexible designed for applicable for a variety of occasions. Offering a higher capacity up to 64HP,in 2HP as an increments, meeting to the needs of requirements. It also incorporates numerous outstanding features, a large capacity range of outdoor units and indoor units, longer level difference and actual piping and high external static pressure.
The VRF product provides a flexible design and easy installation in big-sized and high-rise building for wide application

Mainly Features:

1. HIGH EFFICIENCY

High efficiency VRF with high efficient DC compressor and DC motor, realized an EER up to 4.29 (8 HP) and achieved the world’s Top Class energy efficiency. Enhanced Rated Heat Capacity. Wide operation Range. No matter in extremely cold winter when outdoor temperature down to as low as -4°F(-20°C)or in hot summer when temperature is up to 118°F(48°C), the V4+ system will keep stable operation. Intelligent defrost improve the heat capacity.

2. ENHANCED COMFORT

Intelligent soft start technology

DC inverter compressor soft start function reduces strike to the electric network. This kind of high-performance and low sound scroll compressor operates at a faster rate when starting, reducing start-up time. It helps the unit to bring the room temperature up to the set level quickly.8, 10HP(7.2,8Ton)

Utilizing the scroll compressor benefits,VRF system can reach full load quickly and shorten warm-up or cool-down time for an immediately.Quick warm-up & cool-down design

Nighttime silent operation mode

OlyAir's Night Silent Mode feature which is easily set on the PCB board allows the unit to be set to varies time options during Non Peak and Peak operation time optimizing the units noise output. Extra silent operation mode can reduce sound level further, minimum 46.8dB (A). Nighttime silent operation will be activated X hours after the peak temperature during daytime, and it will go back to normal operation after Y hours.

3. High efficiency oil balance and oil return technology

Oil balance pipes among modules and individual oil balance by vector control ensure even oil distribution among the
modules which keeps compressor running nomally. High effciency centrifugal oil separator(up to 99%)
makes oil separate from discharge and go back to compressor. Auto oil return program by monitoring the running time and state of system ensures reliable oil return.

4. HIGHER RELIABILITY
In one combination, any of the outdoor unit can run as the master outdoor unit, to realize the equal lifespan among the outdoor units in the combination. Alternative Cycle Duty operation of outdoor units. Any single unit can be set as the master unit in a multiple system when the previous master unit failed and other units left will keep on operating. This can be set on PCB by DIP switches at site.Outdoor module Back up operation.

5.FLEXIBILITY DESIGN FOR BIG SIZED BUILDING
The outdoor units capacity range from 8HP up to 64HP (7.2~51.5 ton) in 2HP increment.Maximum 64 indoor units with capacity up to 130% of total outdoor units can be connected as one refrigeration system.Large capacity for big sized building.
