Feature of Outdoor Units

1. High Efficiency

2. Convenient Installation

3. Quiet Operation

4. Precise Control

5. Protection & Reliable

1. High Efficiency

Equipped with high efficiency DC Inverter compressor and DC fan motor,advanced 180?sine wave vector driver, the system can be higher than 4.0 in SCOP so as to meet the European new energy efficiency standards.

0.5W Standby

Intelligent technology enables Ecostar products to cut energy consumption from normal 5W to 0.5W per hour when standby, which counts 90% ofsaving.

180? Sine Wave Control

Ecostar has the most advanced 180?sine wave DC inverter compressor drive? technology and active PFC technology make quieter and more economical? operation.

Optimized Pipeline Design

The refrigerant inlet and outlet are separated, to ensure the sub-cooling,? enhance the cooling capacity.

2. Convenient Installation

Long Piping

? Long piping design, the maximum pipe length can be up to 50m.

? If the connection pipe is too long, the cooling capacity would be decreased.

3. Quiet Operation

Quiet Motor and Fan

The advanced DC brushless motor for both indoor and outdoor unit, adjust
fan speed according to the system pressure and decrease the noise.

Muffler

The system using muffler to eliminate system noise.

4. Precise Control

Fast Cooling & Heating

According to the heating effect of condenser (dirty, blocked, aging, poor
ventilation), the compressor can automatically calculate an appropriate rate
to the target frequency, ensure that the output capacity can achieve fast
cooling and Significantly improved the stability and comfort.

EXV Adjustment

According to the suction superheat and discharge superheat, the EXV is adjusting
the refrigerant volume accurately to ensure the capacity and reliability.
Supply stable room temperature and provide customer comfort feelings.

Reliable Oil Return

Unique oil separator, ensure the effect of oil return under the long pipe, and
low frequency.

Intelligent Defrost

? The defrosting times and time can be adjusted automatically according to the environment temperature, the defrosting time decrease 25%.
? The intelligent defrost function enhances heating efficiency by 10%.

5. Protection and Reliable

Wide Operation Range

No matter when it is as high as 52? in hot summer or -15? in cold winter, the? unit could operate perfectly, making you feel like spring all year around.

Cooling range: -10~52?

Heating range:-15~24?

Double anti-corrosion

The housing of outdoor unit is made of galvanized metal, then enhance its corrosion resistance through the powder spraying technology, which can? improve its anti-corrosion ability 3 times in coastal regions.

Stress Analysis

Analysis piping stress distribution in transportation and running process,
improve the reliability of the structure.

The amplitude Analysis

Analysis piping amplitude and displacement in transportation and running process, to find piping vibration patterns and come to solutions.
