The series chillers used the famous twin-screw compressor for full fluid dedicated compressor ,efficient flooded evaporator design , evaporator inlet refrigerant flow plate and imports are high-quality electronic expansion valve, refrigerant boiling in the evaporation process of the formation of flexible optimization of temperature, so a perfect match, so that unit energy efficiency as high as 5.8 or more.  (Standard conditions for the evaporation temperature machine  5 °C  )
   Acid liquid energy efficient units dedicated full water temperature can reach  15 °C  (The highest evaporation temperature is set  12 °C  ).  It reached the limit of the compressor's operating range. The EER is as high as 6.42 or above.
