1. Adopt the flooded evaporator design, uniform distribution of refrigerant, and optimized temperature field to get higher heat transfer efficiency.

2. The advanced double compressors are designed in parallel with a single system, and the compressors are alternately operated during part load, so as to extend the service life of unit.

3. Through accurate detection of the liquid level in the evaporator, the microcomputer automatically calculates the optimal liquid supply amount; the electronic expansion valve is quickly and accurately adjusted to ensure that the liquid level in the evaporator is always at an optimal level, making the unit maintain the highest operating efficiency at every load point.

4. The unique evaporator oil extraction combined with ejector pump oil return technology ensures that the unit can reliably return oil at any load point.

5. The built-in efficient condenser of oil separator can realize middle diversion, bottom supercooling, low refrigerant pressure drop, and high heat transfer efficiency.

6. Large-size color image display touch screen ensures flexible and reliable unit control.
