Two-stage Subcooling

Two-stage Super-cooling Cycle Diagram Two-stage Super-cooling Pressure Enthalpy Diagram

A subcooling section is designed in the heat exchanger of outdoor unit to realize the first-stage subcooling. Furthermore, a high efficient double pipe is applied to achieve the second-stage subcooling. The total subcooling degree is up to 27℃ , which improves cooling capacity and increases the total piping length.

Hisense VRF adopts newest high-pressure-chamber compressor, which provides higher compression ratio, smoother oil supply and lower noise level.

Exclusive Asymmetric Scroll

Core TechnologiesSpecialty because of dedication, Leading technology casting high quality products.

The accumulator adopts porous oil return technology with a built-in fine strainer, which not only ensures oil balance between compressors within one module, but also plays an important role in the oil balance between modules.

Except for this, the system implements oil-return operation based on compressor frequency and corresponding operation time. The oil-return operation takes 60 seconds, and can return to previous operation state when it’s done.

In winter under heating mode, this operation is implemented without changing to cooling, which guarantees heating effect.

Oil Separation

First-stage oil separation is realized through efficient oil separation structure inside high-pressure-chamber compressor. Only a small amount of oil is brought out of the compressor.

During second-stage oil separation, the small amount of oil discharged from compressor is separated by a large-capacity, high-efficiency centrifugal oil separator, with efficiency over 99%.

High Quality User Experience

Outdoor Unit Noise Control

In accordance with application situation and structure, Hisense has been studying the technical and installation methods for noise reduction of indoor units from various aspects of fan motor, fan blade and air duct layout, which provides customers with the quietest air conditioned environment.

First-class scroll compressor ensuresminimum vibration and noise.

Aluminum-casted motor with nonresonant hanger structure provides stable motor performance and attenuates vibration noise.

The axial fan is made out of noise–absorbing material, which also has a shape that decreases turbulence around.
