Centrifugal water-cooled chiller unit

Superior load performance

Compact structure

Low operating costs

Compact structure

1. Use R134a refrigerant, which is an internationally recognized environmentally friendly refrigerant and an HFC working fluid.

2. R134a is a positive pressure refrigerant that does not require an exhaust system, and the ventilation design of the computer room is simple.

3. Use Hanzhong two-stage centrifugal compressor.

4. Use an efficient falling film (spray) evaporator.

5. The unit is equipped with an oil cooler, which is cooled by refrigerant and does not require maintenance.

6. Use an independent oil return system (injection pump oil return) to ensure timely oil return under any load conditions.

7. The oil pump is built into the oil tank of the compressor unit, so there is no risk of leakage.

8. The unit adopts a fixed orifice plate throttling device without moving parts, which can adjust the refrigerant flow in a timely manner under variable loads and working conditions without hysteresis, ensuring stable operation of the unit.

9. The dedicated microcomputer control system for the crew uses Chinese graphics to clearly display various operating data, making operation extremely convenient.
