The working principle of chiller

The refrigerating working medium absorbs the heat of the cooled substance in the evaporator and vaporize into steam. The compressor constantly extracts the generated steam from the evaporator and compacts it. After compression, the high temperature and high pressure steam is sent to the condenser to release heat and condense into high pressure liquid to… Read more The working principle of chiller

The difference between air-cooled chiller and water-cooled chiller

The functions and refrigeration methods of air-cooled chiller and water-cooled chiller are the same. The overall structure and operation curcult are the same except for the condenser. The air cooled chiller adopts fin type condenser, which takes away the heat of refrigerant by forced air flow directly from the fan. Water-cooled chiller adopts shell and… Read more The difference between air-cooled chiller and water-cooled chiller

The advantages and disadvantages of the different types of chiller

Screw chiller Screw chiller is a unit that uses various types of screw compressors as the main engine. It is a combined refrigeration device composed of screw compressor, condenser, evaporator, thermal expansion valve, oil separator, automatic control components and instruments. The typical cooling capacity is from 700KW to 1000KW. Advantages: Simple structure, less parts, less… Read more The advantages and disadvantages of the different types of chiller

The cooling circulation system is used to collect the non-condensable tail gas in the distillation system

Most rectification towers are two-stage condensation. The first stage uses cooling water, mainly condensing the top steam, and the second stage uses chilled water or ethylene glycol, which is mainly used to treat tail gas and remove a small amount of light components. The exhaust gas is condensed. Therefore, the secondary condensation is very small.… Read more The cooling circulation system is used to collect the non-condensable tail gas in the distillation system

Refrigeration unit for the circulating cooling water of the quench tank

The quenching tank is a container filled with quenching medium. When the workpiece is immersed in the tank for cooling, it must be able to ensure that the workpiece is uniformly quenched at a reasonable cooling rate. It is a container that provides sufficient cooling capacity for the quenching of the workpiece to meet the… Read more Refrigeration unit for the circulating cooling water of the quench tank

Method for controlling shutdown of water cooled chiller of single reaction kettle

In order to maintain the stable performance of the refrigerator during long-term operation, it is necessary for the user to master the method of stopping the operation according to… Read more Method for controlling shutdown of water cooled chiller of single reaction kettle

The use efficiency of the ultra-low temperature chiller can be more efficient

The structure of the ultra-low temperature chiller is more complicated. Its main function is to provide cold air to the product, which is the refrigeration function. If you want to improve the efficiency of the freezer, you must pay attention to the following issues. First note: it must be cleaned and maintained regularly. Clean-up is the most… Read more The use efficiency of the ultra-low temperature chiller can be more efficient

Precautions for maintenance of cooling systems for laboratory instruments

Industrial refrigeration units dedicated to laboratory instruments are used more in the pharmaceutical and chemical industries, and care must be taken when using them. The daily maintenance of refrigeration units for laboratory instruments is mainly reflected in the following aspects: 1. Condenser The high-temperature and high-pressure Freon of the refrigeration system of the industrial refrigeration… Read more Precautions for maintenance of cooling systems for laboratory instruments
