Many people who purchase the constant temperature and humidity test chamber will have such a question. The person who sends the constant temperature and humidity test chamber will remind that "it is best not to turn on the constant temperature and humidity test chamber within two hours." The relevant engineer.
The engineer explained that the main reason is that the compressor of the constant temperature and humidity test chamber refrigeration system needs lubricant protection. The manufacturer of the constant temperature and humidity chamber will put a certain amount of lubricating oil in the refrigeration system and seal it inside. . During the transportation of the constant temperature and humidity test chamber, after a period of bumps, the lubricating oil of the constant temperature and humidity test chamber is likely to flow into the middle of the coil of the heat exchanger.
If the bump is severe and tilting occurs, the lubricant may also enter the cylinder of the compressor. Once used immediately after delivery to the laboratory, the lubricant in the pipeline will hinder the flow of the refrigerant to a certain extent, and if there is oil in the cylinder, it will affect the compressor operation.
If the problem is serious, then the lubricating oil will cause the liquid to hit the broken cylinder, making the operation of the constant temperature and humidity test chamber paralyzed. Therefore, after placing the constant temperature and humidity test chamber, wait for two or three hours to allow the lubricating oil in the constant temperature and humidity chamber to sink and use.
