Introduction to Low Temp Chillers

Low temp chiller is a kind of refrigeration equipment which can provide cold source below 0℃. It generally refers to the use temperature from 5 to 35℃. The refrigerant can be carried by ethylene glycol or calcium chloride aqueous solution, and the evaporator with higher concentration needs anticorrosive treatment. The compression ratio of low temp chiller to the compressor is higher, so most cryogenic fields adopt a more complex system than a single compressor. Cascade compression or two-stag...

How to Maintain Low Temp Chillers

Low temp chiller is a kind of refrigeration mechanical equipment which needs to be used in many industrial production operations. It can provide very good refrigeration technology for different production operations and ensure the smooth progress of various industrial production. Most low temp chillers are composed of two systems -- refrigeration system and frozen water system. The refrigeration system adopts imported refrigeration accessories with high reliability and automatic protection de...

Descrizione dell'alimentazione del chip driver nel sistema di controllo della temperatura del chip test

The chip test temperature control system is mainly for the cold heat source test equipment for various drive chips. Before the operation of the Wuxi Guanya chip test temperature control system, the user needs to know the power of the drive chip. In general, constant current drive and constant voltage drive are the two main choices in drive selection. In fact, in terms of the development status of LED power supply, these two modes are currently common drive modes on the market, LED drive power...

Cosa sapere sui refrigeratori criogenici centrifughi prima dell'uso?

There are some differences in the use of cryogenic chillers between different compressors, but not very much of it. Due to the different styles of different compressors, the points to pay attention to during operation are also different. For example, what should we know about centrifugal cryogenic chillers before the operation? Before we understand the centrifugal cryogenic chillers, we first learn to understand the structure of centrifugal cryogenic chiller which is mainly composed of centri...

Types of Environmental Tests

The environmental chamber is one of the many types of experiments used in scientific research, product development, production and evaluation. The fundamental difference between environmental tests and other tests is that there are specific requirements for the environmental conditions of the tests. Its purpose is to obtain the product material, the change of the structure, function, performance, information of products' physical response characteristics to the environmental stress and ultima...

Performance Test of Household Refrigerator Designed by Environmental Chamber Sales

Many performance items of household refrigerators are tested under a specific environmental condition. The thermal condition of the air distribution in the environmental chamber is more severe than that in the general artificial constant temperature and humidity climate chamber. Therefore, it is difficult to arrange the air supply system in accordance with the usual air conditioning design method to meet the needs of the refrigerator test environment. At present, there is no systematic and ma...
