Technical Parameter
High-Efficiency Compressor
Featuring a world-class high-efficiency semi-hermetic twin-screw compressor with German technology, the rotors are manufactured with precision to the micron level, offering optimal airflow channels and clearances, which significantly enhance the compression efficiency.
Infinite Adjustment
Standard equipped with a slide valve for infinite adjustment, which can precisely match the changes in air conditioning load, effectively avoiding the frequent starting and stopping of the compressor during partial load, providing more accurate control and maximizing operational cost savings.
High-Efficiency External Oil Separator
High-efficiency centrifugal cyclone oil separator reduces the oil content in the refrigerant entering the evaporator, ensuring efficient heat transfer in the heat exchanger.
Ultra-High Efficiency Heat Transfer Technology
Utilizing ultra-high efficiency evaporation tubes, designed with special heat transfer surfaces tailored to different heat transfer mechanisms and fluid media, achieving optimal heat transfer efficiency while reducing pressure losses in the flow path, thus decreasing the energy consumption for users.
Electronic Expansion Valve
The world's advanced electronic expansion valve offers high control precision and performs excellently under both full and partial load conditions.
High-Efficiency Shell and Tube Condenser
Equipped with the latest imported high-efficiency condensing tubes and specially designed fin shapes on the outside surface of the tubes, which effectively disrupt the formation of condensate films, significantly increasing the heat transfer area and thus enhancing the condensation heat transfer effect.
