Outdoor Units

This large-capacity, high-pressure chamber scroll compressor features a unique internal oil separation mechanism. The internal oil separator and internal oil return pipe design ensure that the majority of the lubricating oil remains in the compressor, effectively eliminating any capacity loss caused by excess refrigerant oil in the refrigeration cycle. Additionally, the anti-compression technology prevents excessive pressure, reducing power consumption and ensuring stable and efficient operation.

The operation range is from -5℃ DB to 52℃ DB in cooling mode and from -25℃ WB to 16.5℃ WB in heating mode, adap ting to diverse environments and extreme conditions.

The YORK Topflow series, featuring ART technology, is equipped with an automatic temperature adjustment system for evaporation (Et). The evaporation temperature will be set to a higher level when the indoor load is low and vice versa, thus optimising energy efficiency.

York VRF's innovative 2-stage subcooling technology offers a significant enhancement to cooling capacity compared to conventional systems, allowing the system to reach a subcooling temperature of up to 27℃.

The DC inverter motor incorporated into the outdoor unit allows for seamless and precise fan speed adjustment, ensuring optimal efficiency and stability. The optimised motor support structure allows for an increase of 10% in air volume at the same speed while significantly reducing noise output.

The refrigerant cooling technology ensures optimal performance of the electrical control box even in challenging environments with limited heat dissipation or elevated ambient temperatures. The temperature inside the electrical box can be reduced by up to 20%* in comparison to air-cooled technology. The refrigerant cooling kit is equipped with a temperature sensor, enabling precise temperature control and enhanced reliability.

When an IDU breaks down and under repair, the other units can operate normally without any disruption.

As the system expands, the number of indoor units will increase, and the addressing of IDUs will become more complex.The YORK Topflow series offers an automatic addressing function for indoor units, streamlining installation and commissioning.

One-touch refrigerant recycle is also available in YORK Topflow series. With a simple press on the button of PCB, the refrigerant can be recycled immediately.

YORK Topflow series are equipped with a service window on the protection panel of electrical box to check the parameters.

YORK Topflow series has separated mechanical and electrical compartments covered with independent panels to provide convenience on installation and maintenance. Service Engineers can take the panels apart to check and maintain every details conveniently.

High-efficiency DC inverter twin rotary compressor is featured with unique dual-pressure chamber design, effectively reducing vibration and noise and improving the compressor performance especially under low-speed operation. Moreover, it has a small lubricating oil injection volume, stable oil return, and a gas -liquid separator, which makes the whole system more reliable.

Longer and more flexible piping helps overcoming various piping obstacles.

Refrigerant cooling technology is used to cool the electrical control box, maintaining efficient operation even at harsh environment with poor heat dissipation or high ambient temperature.

Wider operation range creates greater application. The operation range is from -5℃ DB to 52℃ DB in cooling mode and from -21℃ WB to 17℃ WB in h eating mode, adapting to diverse environments and extreme conditions.

High external static pressure up to 30Pa ensures that the outdoor unit runs with a good ventilating condition.

The intelligent demand mode can adjust capacity output automatically based on peak-valley requirements of electricity. There are three levels setting, 80%, 70% and 60%. It achieves the balance between comfort and energy-saving while meeting the power demand for daily work.
