Core Technologies Specialty because of dedication, Leading technology casting high quality products. 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%. First-stage Oil Separation Second-stage Oil Separation High-pressure-chamber DC Inverter Driven Scroll Compressor Hisense VRF adopts newest high-pressure-chamber compressor, which provides higher compression ratio, smoother oil supply and lower noise level. Asymmetric Scroll Disc Supply Oil According to Pressure Difference, More Stable Big Silencing Chamber, Lower Noise Inner Oil Separating Structure DC Variable Speed Motor Comperssor Suction Line Comperssor Discharge Line Refrigeration Oil Flow Line Oil Return 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. Accumulator 1 Outdoor Unit 1 Outdoor Unit 2 3 4 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. Compressor Frequency High Low t T t Oil Return Operation Time New Scroll Compressor Exclusive Asymmetric Scroll High Pressure Chamber Compressor Two-stage Subcooling 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.
