Knowledge about the compressor of the refrigeration system in high and low temperature laboratories
The refrigeration compressor is one of the important configurations in high and low temperature laboratories, mainly composed of power, machinery, lubrication, cooling, control and other parts. It plays a core role in the refrigeration system of high and low temperature laboratories. In recent years, related to the domestic instrument market, the research topic of refrigeration compressors has never lagged behind. In terms of related advanced technology, the trend of gradually catching up with the foreign technology level of the same period is becoming more and more obvious. The walk-in high and low temperature laboratory is used for heat and cold resistance testing of defense industry, aerospace industry, automation components, automotive parts, electronic and electrical components, plastics, chemical industry, pharmaceutical industry and related products. It provides a large temperature and humidity testing environment space for large parts, semi-finished products, and finished products in the industry, suitable for testing equipment with large quantities and volumes of products. The environmental control cabin of the automobile environment simulation laboratory is a reliable experimental environment in China that can achieve automobile cold start tests, automobile high and low temperature tests, frost and fog simulation tests, harmful gas simulation tests inside the vehicle, and vehicle emission tests. The high and low temperature environment laboratory can be used to assess and determine the storage of electrical, electronic products or materials under high or low temperature environmental conditions caused by temperature cycling changes on the product surface.
According to feedback from market users, many users choose compressor equipment with foreign configurations when choosing high and low temperature test chambers. Of course, domestic compressor enterprise users also have a lot of support: this is because the capacity and characteristics of the compressor determine the capacity and characteristics of the refrigeration system, as well as the performance of the test box. The performance of the compressor is mainly to improve its efficiency, while also being more energy-efficient and reducing material waste. In fact, currently, compressors have disadvantages such as friction, leakage, harmful heat transfer, motor damage, flow resistance, noise and vibration, and there is still a lot of room for progress:
Internationally, the main research and development directions of compressors mainly focus on the following important aspects: studying lubrication characteristics, friction characteristics of compressor bearing parts to reduce trade friction power consumption, and improving compressor efficiency; Reduce information leakage losses to improve compressor efficiency; The use of frequency conversion or variable capacity technology can achieve energy conservation in enterprises by optimizing the matching between the output of the refrigeration system and the user's load. The teaching content related to this aspect needs to be specially designed, as frequency conversion technology is relatively mature and well-known.
Finally, users are reminded to pay attention to the performance of the compressor when selecting intelligent system devices such as high and low temperature laboratories. At the same time, attention should be paid to the maintenance of the compressor during normal use to avoid various causes of compressor equipment failures.
