Magnetic suspension cooling water (heat pump) unit

Product introduction

The magnetic levitation chiller independently developed by Tianrui heavy industry adopts the five degree of freedom full active magnetic levitation bearing technology, which realizes the non-contact suspension support of the high-speed moving parts of the refrigeration compressor, eliminates the mechanical friction and wear and the multi-stage speed increasing device, and does not need lubrication. It overcomes the industrial problem that the lubricating oil in the traditional chiller penetrates into the refrigerant medium to participate in the system circulation and adheres to the surface of the heat exchange tube bundle to reduce the heat exchange efficiency. At the same time, the internal screw tube bundle is used for heat exchange of the chiller, which enhances the flow surge of the refrigerant medium, enhances the heat exchange effect and improves the heat exchange efficiency of the system. In addition, the refrigerant compressor is connected with the adjustable

The diffuser structure is matched, and the aerodynamic efficiency and working range of the compressor are further improved by adjusting the incident angle of the outlet medium. Compared with the screw type chiller, this product has a higher energy efficiency ratio, achieves energy saving of 30% - 50%, and the noise is less than 80 dB. It has the advantages of small volume, light weight and large energy density, and can provide a stable and long-term power for the refrigeration system, energy saving and environmental protection. Therefore, maglev chiller is an iterative upgrading product of the refrigeration industry towards green and intelligent development. It is a green energy-saving equipment that promotes the transformation and upgrading of traditional industries and the conversion of new and old kinetic energy. It provides important technical support for achieving the goals of "carbon peak" and "carbon neutralization".
