Core technology of magnetic levitation centrifugal unit:

Energy saving, efficient, and low operating costs

1. Magnetic levitation compressor technology

The unit adopts advanced technologies such as magnetic levitation compressor technology, DC variable frequency control technology, and oil-free lubrication, which greatly improves the energy efficiency ratio of the product. The highest energy efficiency ratio for partial load of the unit is 26, and the highest comprehensive energy efficiency ratio can reach 12.18.

2. Freestyle Capacity Adjustment

The unit adopts DC frequency conversion technology, and the speed of the compressor can be infinitely adjusted within 2-100% of the load, optimizing the energy consumption of the unit.
3. High heat exchange efficiency

The missing column layout ensures even distribution of refrigerant in each flow path of the unit, and each group of heat exchangers is arranged at a reasonable angle, while equipped with high-performance heat exchange tubes, effectively improving heat transfer efficiency.

4. Suitable for systems with large temperature differences and small flow rates

The larger temperature difference improves the overall efficiency of the cooling water system. Increasing the temperature difference from the conventional 5 ℃ to 7 ℃ or 8 ℃ will improve the heat transfer efficiency of the cooling water and reduce the initial investment of the cooling water system.

5. High temperature effluent, suitable for independent temperature and humidity control system

The variable frequency magnetic levitation centrifugal unit does not use any lubricating oil, so it does not require a return oil pressure difference and can produce high-temperature water (up to 20 ℃). However, ordinary screw units are difficult to achieve high-temperature water production due to the need to establish a return oil pressure difference.

Stable, reliable, and low maintenance costs

1. Aviation alloy materials

The moving parts of the compressor unit are made of aviation alloy materials, with a leading aviation engine turbine design. Its intelligent multi-stage reliability control ensures that the unit can automatically handle unexpected problems in any situation (including power outages, etc.), making operation safer and more stable.

2. Efficient and frictionless

Using advanced magnetic bearing technology to achieve oil-free operation of the unit, completely avoiding the high friction loss of conventional compressor bearings. The management and control of lubricating oil ensure excellent energy efficiency and reliable, long-term wear free operation.

3. Anti surge

The compressor control module provides a control curve for the safe operation of the compressor, which monitors the operating status of the compressor in real time, calculates and judges the speed, and adjusts it in a timely manner to ensure that the compressor always operates within a safe area.
4. Ultra long lifespan

The compressor is made of aviation grade aluminum castings and high-strength thermoplastic electronic casings, which can operate efficiently for a long time and have a lifespan 10 years longer than ordinary units.

5. Magnetic levitation multi head product with high operational reliability

The magnetic levitation multi head product adopts intelligent backup operation technology. When one head malfunctions and stops or undergoes maintenance, the other non operating heads start running. It can achieve non-stop maintenance (providing 80% of the cooling capacity).

Suitable for places such as data centers that have special requirements for unit stability.

Easy installation and low construction cost

1. No impact on the power grid

The starting current is low, with only 2A flexible starting current for a single compressor, eliminating the need for a soft starter. This not only saves tens of thousands of yuan in investment costs for transformer equipment, but also has no impact on the power grid.

2. 380V universal power supply

When starting up, only a low starting current of 2A is required, with a 380V universal power supply. There is no need to apply for a high-voltage power supply separately, eliminating the cumbersome approval process and saving installation costs; Magnetic levitation units have no oil system, maintenance free, and save operating costs.

■ Excellent performance and high comfort

1. Accurate temperature control

By using a magnetic levitation variable frequency compressor, the unit can achieve continuous intelligent adjustment of 2% to 100% load, with an accuracy of ± 0.1 ℃ in water temperature control, small temperature fluctuations, and high comfort.
2. Silent and vibration free

Magnetic levitation bearings allow the moving parts to be completely suspended, and the compressor operates without friction inside. The structural vibration is close to zero, and the operating noise is low, without the need for expensive shock absorption accessories.

3. Green and environmentally friendly

The unit uses environmentally friendly refrigerant R134a, which has an ozone depletion value (ODP) of 0 and is a positive pressure refrigerant, avoiding the danger of air mixing into the system.
