2) magnetic VFD oil-free centrifugal compressor

Unit cooling capacity range: 560KW-7800KW
Chilled water outlet temperature range: 5-20℃.

In addition to standard specifications, various types of non-standard units can also be customized according to user requirements.

Structure of magnetic centrifugal chiller with VFD:

Features of Water-cooled magnetic centrifugal chiller with VFD:

1) COP up to 6.7 (GB condition)
2) IPLV up to 11.6 (AHRI condition)
3) The operating noise of the unit is less than 74dB(A)
4) Patented high-efficiency falling film evaporator
5) Oil-free design of the system, more efficient and energy-saving
6) Adopt Hanbell two-stage maglev centrifugal compressor
7) High-efficiency liquid-cooled inverter cabinet, small size and high efficiency
8) M-Smart intelligent control system realizes quick start, stop and restart

Advantages of magnetic centrifugal chiller with VFD:

1) High-efficiency
It can save 350,000 yuan in one year of operation and 700,000 yuan in two years. Running for 2 years can save a Mercedes Benz, 2 years payback period.

2) Safe & reliable
Magnetic centrifugal compressor;
Active magnetic levitation bearing &intelligent judgment of surge area;
Timely adjustment of speed and IGV to avoid surge;

3) Environmentally-friendly
Using the world's mainstream environmentally friendly refrigerant R134a, it has good comprehensive performance, and the ozone depletion value (ODP) is 0.

4)Condensation heat energy recovery, free and practical (optional)
Has a patent for heat recovery. Using the patented heat recovery device, the waste heat generated in the refrigeration process is recovered. That is, while providing customers with cold water, a large amount of hot water can also be supplied free of charge.

5)High efficiency heat exchanger with excellent performance
The high-efficiency heat exchanger independently developed and produced is used, and the liquid level is controlled by the electronic expansion valve combined with the liquid level sensor to ensure that the evaporator is always in a high-efficiency heat exchange state.
IPLV reaches 10.7, part load energy efficiency value exceeds 13

6)Magnetic oil-free technology, energy saving and noise reduction
No mechanical friction, noise less than 74dB(A)
Magnetic bearing, reducing energy consumption by 10%
The system is oil-free, reducing the heat exchange loss of the heat exchanger, improving the performance of the heat exchanger, eliminating the complicated oil circuit system and simple maintenance.

What is the energy saving and cost saving cooling system for sand mill in printing ink factory

The development of Chinese ink industry can be traced back to the beginning of the 20th century. Since the reform and opening up, the domestic ink market has developed rapidly, and inks have been widely used in various media such as paper, metal, glass, and plastic. In recent years, affected by the further advancement of environmental protection work, the price of some chemical raw materials has risen, and the growth rate of Chinese ink industry has gradually slowed down. In the past three years, the growth rate has been about 3.5%. The profit margin has also shown a downward trend. Oversupply has appeared in some regions. Ink sales have become fiercely competitive. In order to meet the needs of market competition, energy saving and consumption reduction and product quality improvement will be a major rule for ink manufacturers to enhance their corporate competitiveness. However, the research process is a key process in the ink production process, which has a key impact on both yield

How to manufacture the shell and tube heat exchanger I

Shell and tube heat exchanger is a kind of heat transfer device, which is composed of shell, tube plate, tube bundle, baffle and cover; How is the manufacture to produce the shell and tube heat exchanger ? In the manufacturing of heat exchanger, the manufacturing process of cylinder, head and other parts is the same as that of general container manufacturing progress, but the requirements are different. The inspection of materials, drilling of tube plate and baffle hole, welding of cylinder and processing of flange are the key points to the quality. Throughout its manufacturing process, most of manufacturer still use traditional processes, in which the proportion of welding is relatively high, so it is necessary to weld in strict accordance with the welding process, and to detect the weld. The heat exchanger produced by H.Stars Group subsidiary company UAR, has gone through 18 processes. It has been meticulously processed in the heat exchanger process, providing two products with gua

The Role and Characteristics of Condenser in Refrigeration System

The four major components of the refrigeration system are compressor, evaporator, condenser and throttling device. The role of the condenser in the refrigeration system is mainly to cool and liquefy the gaseous refrigerant in the high temperature and high pressure state discharged from the compressor, so as to meet the requirements of the circulating use of the refrigerant in the system. The selection of the temperature difference between the condensing temperature and the coolant inlet and outlet involves economic issues in the refrigeration system. Increasing the condensation temperature and reducing the temperature difference between the coolant inlet and outlet can increase the heat transfer temperature difference, reduce the required heat transfer area, and reduce the investment cost of heat exchange equipment. However, lowering the condensing temperature can reduce the power consumption of the refrigeration compressor. The greater the temperature difference between the coolant
