Knowledge topic about refrigeration compressors for high and low temperature test chambers

Refrigeration compressor is one of the important configurations of high and low temperature test chamber. It is mainly composed of power, machinery, lubrication, cooling, control, etc. It plays a role in the heart of high and low temperature test chamber refrigeration system. In recent years, it is related to domestic In the instrument and meter market, the research topic of refrigeration compressors has never fallen. In terms of relevant advanced technology, the trend of gradually overtaking the technical level of foreign countries has become more and more obvious.
From the feedback information of market users, many users choose equipment with foreign compressors when they choose high and low temperature test chambers. Of course, there are also many users who support domestic compressor companies; why are refrigeration compressors for high and low temperature? Is the quality of the test chamber critical? This is because the capacity and characteristics of the compressor determine the capacity and characteristics of the refrigeration system, which in turn determines the performance of the test chamber. The performance improvement of the compressor is mainly to improve the efficiency of the compressor, and at the same time to save energy and reduce material waste. In fact, current compressors have many disadvantages due to friction, leakage, harmful heat transfer, motor loss, flow resistance, noise vibration, etc.
Internationally, the main research direction of compressors mainly focuses on several aspects: lubrication characteristics, friction characteristics of compressor bearing parts to reduce frictional power consumption, improve compressor efficiency, reduce leakage loss to improve compressor efficiency; The variable frequency or variable capacity technology achieves energy saving through the best match between the output of the refrigeration system and the user load. In this regard, the frequency conversion technology is relatively mature and well known.
Finally, the user is prompted to pay attention to the performance of the compressor when selecting intelligent system equipment such as high and low temperature test chambers. At the same time, pay attention to the maintenance of the compressor during normal use to avoid various causes caused by the compressor. Equipment failure.
