1. During the review of design specifications and air cooler design calculations, we analyze the parameters of similar products and believe that this equipment will have a larger heat exchange area, and occasionally, its return gas temperature may be relatively low, although this situation is not very common.

2. When used in conjunction with the equipment, it may leak after the pressure is increased, which will raise its temperature and blow it away. After the equipment is operational, the temperature difference at its hot end is slightly smaller, indicating that ice and dry ice are not the main reasons for the excessive temperature difference after clogging.

In the airflow channel of an air cooler, if no impurities are blown out when the pressure reaches 0.45 MPa, then there are no impurities in the airflow channel, or there are no impurities that can pass through.

After analyzing the data from the equipment control system, it may be discovered that the large temperature difference is caused by the bias current of the air cooler.
