1. The full liquid evaporator design adopts high-efficiency heat exchange steel pipes, and the evaporation pipes are completely immersed in boiling liquid refrigerant, enhancing the heat exchange effect on the water side and refrigerant side, effectively improving the refrigeration capacity and energy efficiency ratio of the unit;

2. The compressor adopts a slide valve to achieve stepless capacity adjustment, smoothly adapt to changes in air conditioning load, and improve the energy efficiency of partial load operation;

3. A uniquely designed oil return system with an external high-efficiency oil separator and a unique oil return device ensures complete oil return;

4. The uniquely designed throttling device can automatically adjust the flow rate with changes in load, establish a stable system pressure difference, and operate more economically and reliably;

Power: 67.1~780.8 kW
