Overview

The Leitz magnetic levitation chiller uses environmentally friendly refrigerant R134a and adopts two-stage compression to easily meet the high pressure ratio requirements of the compressor in ice storage conditions. More importantly, it uses high-speed permanent magnet variable frequency motor and its variable frequency speed regulation technology to ensure that the unit is more efficient in both cooling and ice making conditions, saving more than 40% energy compared to traditional fixed frequency ice storage units. It is widely used in large office buildings, hospitals, schools, shopping malls, and process flow.

Product Details

LeitzMagnetic levitation chiller unit6 core advantages

01 Long service life

The magnetic levitation compressor adopts new materials from aerospace technology, with a service life of up to 30 years.

02 No vibration

The magnetic levitation compressor operates without friction inside and has low operating noise.

03 Low starting current

The magnetic levitation compressor adopts a full DC variable frequency motor, with a starting current of only 2A, and has no impact on the power grid during startup.

04 Efficient and energy-saving

The magnetic levitation centrifugal chiller adopts an efficient heat exchanger design, which fully improves the efficiency of the magnetic levitation unit under partial load, and the comprehensive energy efficiency ratio can reach over 11.5.

05 oil-free system, high heat exchange efficiency

The magnetic levitation compressor adopts permanent magnet bearings, which suspend the bearings frictionlessly during operation, eliminating dependence on lubricating oil and improving heat transfer efficiency.

06 Sensitivity of load regulation

Magnetic levitation chiller unitThe load can be continuously adjusted between 10% and 100%. Adopting a full DC variable frequency compressor, the response to load is fast, ensuring timely output of cold station cooling capacity in case of sudden changes in usage conditions, and improving user experience.

1. Adaptive feedback load control technology

Automatically calculate the required cooling capacity of the cold water system based on the end load, simulate the combination of the main engine, water pump, cooling tower, and valves in advance, and compare them with the database in real time to optimize the operating data in advance, ensuring efficient and stable operation of the system.

2. Full frequency conversion efficient fusion control technology

The chiller unit adopts a fully variable frequency design, and the power curve of the selected chiller unit is pre programmed into the centralized control system. Based on temperature and pressure sensing signals, the frequency and energy consumption curves of each component combination under different loads are automatically found to achieve the desired energy state.

3. Automatic equalization conversion technology

When the equipment suddenly malfunctions during operation, it can automatically put the backup equipment into operation without stopping the machine. At the same time, it has the function of counting the running time of the equipment and balancing the operation scheduling, realizing automatic conversion, intermittent operation, and extending the service life of the equipment. Flexible combination of units, strong applicability in design and installation.

4. Association prediction

Establish a fault diagnosis model for the associated parameters of the chiller unit operation, predict the reliability of key components through the trend of data operation, avoid sudden shutdowns, and infer future energy consumption data based on user usage habits, establish corresponding databases, and provide safety guarantees for the long-term operation of the unit.

5. Big data visualization analysis

Based on the big data uploaded to the remote service platform, an analysis model is established to visually display the operation of the chiller unit in the form of charts, and energy-saving solutions and control strategies are provided to facilitate real-time optimization of the chiller unit operation.

6. Remote maintenance and unmanned operation

All operating parameters can be uploaded in real-time to the remote service platform through the MODBUS communication protocol, achieving a three in one platform of centralized control, host, and software and hardware. Operations and management personnel can modify core parameters and operating status, block control, and other terminal service modes at the remote service terminal without on-site operation, thus achieving efficient remote maintenance and unmanned operation.
