Accumulator part
The evaporator has high heat transfer efficiency for evaporation and good cooling effect.
It can ensure long-distance liquid supply.
The system is simple and reliable to operate, convenient for centralized control and automation, and the operating conditions of the refrigeration compressor are improved;
defrosting operation is simple.
Centralized machine room.

- The liquid level sensor AKS4100U can monitor the liquid level height inside the container in real time and transmit the liquid level height signal to the liquid level controller EKE347.
- After the liquid level controller EKE347 (PLC) receives the actual liquid level signal, it compares it with the preset ideal liquid level height, and then sends a valve opening signal
recommendation to the actuator ICM electric expansion valve.
- The ICM electric expansion valve adjusts proportionally from 0- 100% opening and can display the real-time opening.
- In addition, this solution requires a float switch AKS38 to be configured as a high liquid level alarm signal.
- Using Venturi hot gas injection oil return technology, in the circulating tank, the oil-rich layer redirects refrigerant liquid containing abundant refrigeration oil back to the injection oil return device, and then back to the suction side of the refrigeration unit, which is simple, efficient, and achieves good oil return.
